Sesshōmaru

was a powerful dog daiyōkai, feared throughout the Feudal Era. He was the half-brother of the hanyō Inuyasha and the first son of the Inu no Taishō, their father. Unlike many other yōkai, he had no interest in possessing even a single shard of the Sacred Jewel to enhance his powers. On his journey, he was accompanied by a two-headed dragon named A–Un, a demon imp named Jaken, an orphaned human girl named Rin, and eventually Sango's brother Kohaku.

His father
Sesshōmaru was the son of the Inu no Taishō and another dog daiyōkai. He saw his father as the ultimate opponent, wishing to defeat him in combat and take his two legendary swords, Tessaiga and Sō'unga. He talked with his father following the battle with Ryūkotsusei, demanding the two swords be handed over to him. However, when questioned if he had anyone to protect, Sesshōmaru told his father that he did not. After his father died to protect his new hanyō half-brother, Inuyasha, and his human mother, Sesshōmaru began to hate them. He was given Tenseiga instead of the other two swords to eventually teach him compassion.

Search for Tessaiga
Sesshōmaru began his quest for Tessaiga by searching for the place described by a short riddle: "Seen, yet never seen, protected, but never known to its protector". This was the only known clue as to Tessaiga's location. His imp servant, Jaken, suggested they go to his younger brother, Inuyasha, to ask where his father's grave was located. Sesshōmaru and Jaken were then next seen riding on a huge oni-looking demon, attacking a shackled woman in a flying carriage. Inuyasha tried to save the woman, but Jaken attacked Inuyasha with the Nintōjō, getting his attention. Sesshōmaru taunted him for being a half-demon, and asked him where their father's grave was, only to be told that Inuyasha didn't know. Sesshōmaru proceeded to tell Inuyasha that if he didn't answer, he would kill the woman in the carriage, Inuyasha's mother. At first, Inuyasha didn't believe that the woman was his mother. However, Sesshōmaru told him that he had resurrected her and gave her a new body, which later, was shown to have been quite possible due to the power of Sesshōmaru's Tenseiga. After hearing from the woman that she was truly his mother brought back from the dead, Inuyasha attempted to attack the demon and save her. Sesshōmaru ordered the demon to attack them, but before they could get hurt, Inuyasha's mother transported them to a different place. Sesshōmaru was annoyed by Jaken's bothersome plan, and told him that if it should fail, he would kill him.

Jaken went to where Inuyasha was located, where it was revealed that the woman was not Inuyasha's mother, but a demon called the 'Unmother'. The Unmother was a spirit of women who had their children killed by war. To lure Inuyasha into revealing the secret to the whereabouts of Tessaiga, Sesshōmaru then appeared and gloated that he knew where their father's tomb was. He grabbed Inuyasha and pulled a black pearl from Inuyasha's eye. He then used the Nintōjō Jaken carried to open a portal from the black pearl. He and the others jumped in, traveling to the world between the living and the netherworld.

Sesshōmaru entered the skeleton of his late father, and attempted to pull out Tessaiga, but was unable to do so due to a spell on the sword which prevented full demons from touching it. Inuyasha arrived, and tried (but failed) to pull it out. Sesshōmaru then attacked Inuyasha. Kagome, who was knocked back by Jaken, with the sword in her hand, pulled it out by accident. Sesshōmaru, enraged by the fact that a lowly human could pull out Tessaiga, demanded Kagome to submit the sword to him. However, Kagome refused, and threatened that she would cut him with the sword. Inuyasha warned Sesshōmaru to stay away from Kagome for good. Sesshōmaru, who hated humans and half-demons alike, then sprayed toxic sludge upon Kagome, covering her. He also remarked to Inuyasha that Inuyasha's love for humans was what made him weak, just like his mother. Inuyasha was furious, and attacked Sesshōmaru not only because of what he did to Kagome, but also because he insulted the memory of Inuyasha's human mother by claiming she had "dirty blood". Kagome then rose out of the sludge, unharmed because Tessaiga had protected her. She gave the sword to Inuyasha, and Sesshōmaru tested him and the sword by transforming into his demon form, a giant white dog with all his distinguished markings.

Sesshōmaru and Inuyasha started to battle. Inuyasha used Tessaiga, which looked like a useless scrap of metal, to no avail. Sesshōmaru began to fill the inside of his father's skeleton with poison gas, forcing Inuyasha and Kagome to escape outside. Inuyasha told Kagome that she was crazy to think that he needed to believe in the sword to make it work. Kagome started crying, asking if she should give up hope, only to be told by Inuyasha to shut up and let him protect her. As Inuyasha approaches Sesshōmaru to land the finishing blow, the sword started to pulse, and suddenly transformed into a huge fang-like sword. Inuyasha then sliced off one of Sesshōmaru's arms, so he was forced to flee.

Naraku's assistance
A band of outlaws, who had just raided a poor village, were riding through a land where demons supposedly came out at night. They saw someone ahead, and assuming that it was merely a human, started to attack. The "human", actually Sesshōmaru, killed them all with one stroke of his arm. Jaken walked up to him through the grass, and congratulated his master on defeating the men so quickly. Sesshōmaru threw the arm, which he had stolen from a demon he had defeated, on the ground, not able to find a permanent arm to use after Inuyasha had cut off his arm. A man, Naraku in disguise, suddenly appeared behind Sesshōmaru, and offered him a human arm in which was embedded a shard of the Sacred Jewel. He said that Sesshōmaru could not touch Tessaiga because he was a demon, but if he used a human arm, he could. He also gave him a hive that could be used to block the hole in Miroku's hand. Naraku asked Sesshōmaru to use his gifts to defeat Inuyasha for him, an offer which Sesshōmaru accepted.

A huge shadowy claw then zoomed across the sky and started wreaking havoc on a town. It turned out to be another of Sesshōmaru's shadow beasts, and the villagers fled in fear. Sesshōmaru released poison from his hand, and Inuyasha covered his nose with his sleeve and coughed while Kagome, Miroku, and Shippō backed away. Sesshōmaru said that he had come to claim Tessaiga. Inuyasha and Sesshōmaru fought for a while, and Sesshōmaru used his human arm to take hold of Tessaiga. He showed Inuyasha how to slay a hundred demons with one stroke of the blade. They fought for a while before Miroku stepped in and used his Kazaana. Sesshōmaru released the hive given to him by Naraku, and Saimyōshō flew into Miroku's hand. Miroku was poisoned and rendered unable to fight. Kagome ran to get him an antidote, while Inuyasha continued to fight with Sesshōmaru. Miroku and Shippō fought Jaken, who used his Nintōjō, tossing fire at them.

Sesshōmaru was about to kill Inuyasha with Tessaiga when an arrow came flying at it, reverting its transformation. Kagome was seen standing on a hill with her bow and arrow out. She said the next arrow would go in Sesshōmaru's heart, and warned Inuyasha to move away. Sesshōmaru charged at Kagome, but Inuyasha jumped in front of him and took the blow for her. Later on in the battle, Inuyasha managed to tear off Sesshōmaru's new arm, but was stabbed by Sesshōmaru's poison claws in the process. Sesshōmaru and Jaken left, and the insects retrieved the Jewel shard in Sesshōmaru's arm.

Tessaiga and Tenseiga
Sesshōmaru, dissatisfied with his sword, Tenseiga, wished to have the old, absent-minded swordsmith Tōtōsai make him a new one. The unwilling Tōtōsai had Inuyasha defend him, causing the brothers to fight. Tōtōsai revealed the heritage of Sesshōmaru's sword before creating a diversion to allow Inuyasha and the rest of his companions to escape. Soon after leaving Inuyasha and his companions, Tōtōsai was attacked by Sesshōmaru. Once again, Inuyasha battled his brother as Tōtōsai's protector, but had to face Sesshōmaru's newest defense, a dragon's arm. As Inuyasha and Sesshōmaru continued to duel for possession of Tessaiga, both brothers discovered the unexpected power of their respective inheritances, as Inuyasha discovered the true power of his sword, and Sesshōmaru, who called his sword useless, was saved by his father's heirloom.

After the fight, an orphaned human child, Rin, attempted to nurse the injured Sesshōmaru back to health. Though he initially tried to scare her off, she returned to him, heartened at the smallest show of interest. She was mauled to death by some of Kōga's wolves while trying to return to him; Sesshōmaru was initially going to ignore her, but moved by curiosity and prompted by Tenseiga's pulsing, tested the blade on her, cutting down the minions of hell that had come to collect her soul and restoring her to life. He walked off, and Rin followed him, becoming his traveling companion.

Kaijinbō's evil sword
Finding the corpse of the fallen Goshinki and detecting Inuyasha's scent on it, Sesshōmaru took the demon's head to Kaijinbō, the rogue swordsmith and former disciple of Tōtōsai, in order to commission a sword made from Goshinki's head. On the same day Kaijinbō arrived, possessed and wielding his newest creation Tōkijin, Inuyasha had transformed into his human form, and was defenseless. Then, luckily, Tōtōsai appeared and gave Inuyasha his repaired sword, which was too heavy for him to lift. Kaijinbō was then destroyed by his own creation because it was too evil for its maker to wield. Kagura directed Sesshōmaru to Tōkijin, and watched as the demon claimed his sword and wielded it against his brother. While Inuyasha and his friends escaped before they felt the full brunt of Sesshōmaru's new weapon, Kagura decided that Sesshōmaru could be strong enough to destroy Naraku.

The Demon's True Nature
Inuyasha's demonic transformation gave him great power, but no sense of control over his actions, as he killed indiscriminately, which Sesshōmaru discovered when he arrived to gauge his younger brother's power after listening to the wisdom of Bokusenō, a demon-tree and friend of the Inu no Taishō.

The Panther Demons
A group of panther demons came after Kagome for her Sacred Jewel shards, but seemed more interested in attacking Inuyasha and Sesshōmaru. Seeking revenge for the defeat of their master at the hands of Inuyasha and Sesshōmaru's father, they kidnapped Kagome.

Inuyasha broke into the panther demon's barrier using Tessaiga's new ability. After Myōga revealed why the demons were seeking revenge, everyone split up to confront the panthers separately.

To resurrect their master, the panther demons captured entire villages to sacrifice. However, when the master was revived, he unexpectedly killed three of them to return to life, and Inuyasha and Sesshōmaru ended up cooperating to defeat the panther demon leader.

To defeat the panther demon's master, Sesshōmaru used the Tenseiga to bring the rest of the panther demons back to life. Sesshōmaru understood that the other three panther demons lives were taken by the master in order for the master to heal, and thus the master died when they were resurrected.

Naraku's plan
Kagura kidnapped Rin, and threatened Lord Sesshōmaru with her life unless he killed Inuyasha, an ultimatum Sesshōmaru ignored. Inuyasha broke through Naraku's barrier with Tessaiga's newly gained power. Meanwhile, Kagome and the others pursued the lone Jewel shard Kagome sensed, which was Kohaku, who had been charged with guarding Rin.

Naraku was forced to fight both Sesshōmaru and Inuyasha, who worked together to seriously wound Naraku until their sibling rivalry got the better of them. The fight was stopped when Naraku remotely ordered Kohaku to kill Rin before vanishing, which forced Sesshōmaru to leave and save the girl's life.

Kōga and Sesshōmaru: a dangerous encounter
Sesshōmaru and Kōga were both still looking for Naraku. Ginta & Hakkaku were fishing in a stream when Rin and Jaken ran across them. Rin was scared because she was originally killed by Kōga's wolf clan. The wolf demons were scared off by Sesshōmaru, and fled to find Kōga, to find him and Inuyasha fighting. After finding out about Sesshōmaru from Kagome, Ginta and Hakkaku decided to keep Kōga away from Sesshōmaru, thinking he would want to defeat Inuyasha's brother. Of course, this plan failed, and Sesshōmaru and Kōga met but did not fight. Instead, they each helped each other out by saving the other's respective party and went their separate ways.

Mount Hakurei
When Sesshōmaru arrived on Mount Hakurei, he saved Kagome Higurashi, Miroku, and Sango from the poison user Mukotsu, one of the Shichinintai; however, when confronted with the fact that he saved Kagome and the others, he merely said, "I only killed him because he wouldn't answer my questions".

Later on, Shippō told Inuyasha that Kagome, Miroku, and Sango stopped breathing due to the poison. Inuyasha was shocked and started to cry, for he was unable to protect them. Inuyasha went off to be alone, and started cutting down trees and yelling in frustration, seeking vengeance on the Shichinintai and on Naraku. In his daze of anger, Sesshōmaru appeared, and asked him why he was so inconsolable. Inuyasha explained, and Sesshōmaru told him that a half-demon could barely protect themselves, let alone others. Inuyasha, tired of being mocked, said that if he killed Sesshōmaru, he would have the Tenseiga and could revive his friends, to which his brother says a half-demon could never master the sword. Inuyasha started to strike Sesshōmaru, but the illusion disappeared, suggesting it was all in Inuyasha's head to begin with.

After Mukotsu's death, Naraku ordered the five remaining Shichinintai to kill Sesshōmaru as well. Jakotsu and Suikotsu went after him, the former noting that protecting Rin was Sesshōmaru's weakness. Later on, Suikotsu and Jakotsu had Sesshōmaru cornered, threatening to kill Rin if Sesshōmaru made a move. Sesshōmaru pulled an impressive maneuver, tossing away his sword behind him and impaling Suikotsu with it, then dashing ahead into the path of Jakotsu's Jakotsutō and plunging his claws into Jakotsu's heart. However, Sesshōmaru, thinking that was enough to kill them, let his guard down, and as Rin ran away from her captors, Suikotsu grabbed her and aimed to kill her. Jakotsu told Sesshōmaru he would be too late to save her, but suddenly Kikyō arrived, managing to stop Suikotsu with her sacred arrow.

He later watched as Naraku's miasma destroyed the vegetation on Mount Hakurei and many demons escaped from the destroyed barrier. Possibly watching Naraku's attempt to kill Kikyō, Sesshōmaru appeared before Naraku; he believed that since he had emerged from hiding, he had grown stronger. Testing his theory, Sesshōmaru destroyed Naraku's body, but the force of Tōkijin was sent back by Naraku's barrier. He made one final slash that ripped Naraku's head in half. However, he had no success in destroying him for good, watching as he fled once more. When Inuyasha arrived to see Kikyō's broken bow, Sesshōmaru berated his brother for not being able to save her, telling him to chase Naraku instead of yelling at him.

The woman who loved Sesshōmaru
Sesshōmaru came across Sara Asano, a woman who had been watching him recover following his first attempt to take Tessaiga. She offered to grant his wish (to possess Tessaiga), not knowing that his main desire now was to find and slay Naraku for using him. Sesshōmaru told her to do as she wished, believing she might be useful. When Jaken questioned him as to who she was, Sesshōmaru told him that Sara was human once, but never fully became a demon. He later appears when Sara successfully stole Tessaiga, destroying the crow demon she used for transport. Sesshōmaru refused to accept Tessaiga from Sara, claiming he did not need help in defeating Inuyasha, especially from her, and fled into the forest. Sara followed him, and found him at the same tree where he she had first come upon him, when he had lain injured from his first battle from Inuyasha. Listening to her tale of how she came to know him, Sesshōmaru noticed her demonic side had emerged. Inuyasha arrived to reclaim Tessaiga. Sara attempted to restrain and kill him, but Sesshōmaru stepped in the way and struck her, revealing that the demons she made a pact with were using her spiritual powers as a bridge so they could absorb him. Learning Tōkijin's hatred feeds the demons, he temporarily managed to wield Tessaiga and destroy her. As Sara faded into golden dust, he listened to her declare love for him. Once she passed, Sesshōmaru placed Sara's flute in her remains, saying "Go play your flute in the netherworld".

Battle in the Borderland
Sesshōmaru followed the scent of a flood of blood to the decapitated Tekkei, and wondered what had happened. Kagura appeared, and informed him Naraku had gone to the Border between the Living and the Dead to retrieve the final Jewel shard. She led him to the Gate in the Land of Fire; there, he drew Tenseiga, pacifying Gozu and Mezu, and allowing him to enter the gate without being turned to stone. He flew to his father's grave once more, and tried repeatedly to break Naraku's barrier; Naraku taunted him by allowing his superfluous limbs to be destroyed. However, once Inuyasha gained and used the Kongōsōha that broke Naraku's barrier, Sesshōmaru's attack tore him to pieces. Seeing Naraku had fled back to the World of the Living, Sesshōmaru headed back to the gate with Inuyasha's group.

Forever with Lord Sesshōmaru
While searching for Naraku, Sesshōmaru came across a village under attack by bandits, slaying them once they attacked him. Monks arrived shortly after, and questioned if he was responsible for attacking the village; Sesshōmaru created a distraction and left. During his absence, Rin was kidnapped by Ongokuki. Sesshōmaru tracked him down, but found the very same monks he encountered earlier had rescued her and several other children. Knowing that Rin should live with humans, Sesshōmaru was willing to allow her to leave, but intervened when the monks refused to let her decide for herself. Holding back, Sesshōmaru destroyed their charms and told Rin to follow him if she chose to do so, and she did. Sesshōmaru was later taken off guard by a question from Rin: "When I die, will you always remember me?" Though masking his true feelings, Sesshōmaru simply said "Don't say such silly things".

Kagura's death
Kagura, one of Naraku's incarnations, later betrayed Naraku to obtain her freedom. She believed that only Sesshōmaru could defeat him; she also seemed to have romantic feelings for him, just like Sara had. After trying to attack Goryōmaru's temple and getting injured, she fell into a river near Sesshōmaru's group. Recovering, she explained that Naraku was using an orb known as the Fuyōheki to hide his heart, and gave Sesshōmaru crystal shards of demonic energy to help him find Naraku's heart. Sesshōmaru entrusted Jaken to look after the crystals.

During a battle with Mōryōmaru, Sesshōmaru caught the scent of Kagura's blood and Naraku's miasma. Mōryōmaru insulted her, infuriating Sesshōmaru, who quickly concluded the quarrel, breaking Tōkijin in the process. He left the sword behind, choosing to obtain a new one instead of reforging Tōkijin.

Just as Kagura thought she would die alone in the field of flowers, Sesshōmaru appeared before her, much to the wind sorceress's surprise. Sesshōmaru told Kagura that he picked up the scent of blood and miasma. Kagura replied, "I see, you thought I was Naraku. Are you disappointed that I'm not Naraku?" Sesshōmaru replied to her by saying "I knew it was you". He reached for Tenseiga, but then realized that she couldn't be saved. Kagura was happy she got to see Sesshōmaru one last time. She looked up at him and smiled as she died before him, dissolving into the wind. When Inuyasha came right after Kagura died, he asks Sesshōmaru if she suffered. Sesshōmaru simply looked toward the sky and said "She was smiling", and then walked away.

Meidō Zangetsuha
Tenseiga called out to Tōtōsai, and he later stated that the sword told him that Sesshōmaru's heart had felt something it had not before: rage and sorrow on behalf of another, not just himself. Because a technique that sent one's foes directly to the Netherworld was so potent and dangerous in the wrong hands, Sesshōmaru's heart had to be mature enough to wield it responsibly. In this way, Kagura's death helped Sesshōmaru to mature and become a more powerful, responsible individual.



When Sesshōmaru learned how to perform Meidō Zangetsuha, he reflected on Kagura's death, and how Mōryōmaru told him that she had died for nothing. He then thought "I, Sesshōmaru, will be the one to decide if she died for nothing". The wind then blew, which Rin pointed out, and the group of three left Tōtōsai. The wind was meant to represent Kagura's spirit.

Rin's second death
In an effort to strengthen and enhance Tenseiga's powers even further, Sesshōmaru visited his mother in search of a way to make a complete Meidō. He ventured into Hell after a demon from the underworld grabbed Rin and Kohaku; the latter was sill alive, due to the Jewel shard in his back, but Rin did not regain consciousness. Sesshōmaru felt regret, believing he should never have brought her along and should had left her in a human village; he felt frustration and blamed himself for her death. Sesshōmaru's mother offered him a way out of the underworld, which he declined, offending her. Sesshōmaru found Rin in the grasp of the master of Hell. After he slayed the demon, he realized Rin wasn't reviving, and stated that enhancing and strengthening his sword was not worth the price of Rin's life. Dead bodies in Hell surrounded them, and with his grief for Rin, he used Tenseiga to purify them. When he returned to the living world with Rin's body, his mother scolded him for thinking he was a god who could control life and death, and told him Tenseiga can only revive the same person once, and that when his heart wished to save his "loved one", he must also at that moment feel both sadness and fear, this being what it means for him to have "a compassionate heart." Sesshōmaru could only learn to understand the worth of a life and gain a truly compassionate heart when the life that was worth the most to him was lost, and "a compassionate heart" was what was necessary for the one who wields a destructive Tenseiga, which could dispatch enemies to the Netherworld.

His mother told him not to expect her to do this twice, placing the Meidō Stone around Rin's neck. Much to his relief and happiness, Rin was revived once more. His mother asked Jaken if Sesshōmaru was happy when she revived Rin, and Jaken responded that he was "extremely so".

Bakusaiga and the final battle with Naraku
Sesshōmaru realized his true potential as a greater demon after Tenseiga's fighting technique, Meidō Zangetsuha, was given to Inuyasha. Sesshōmaru let go of his obsession with Tessaiga in a battle with Magatsuhi, and regained not only his left arm, but also his own sword, Bakusaiga.

He later used this sword to fight Naraku along with Inuyasha's group in the final battle, aiding in the final destruction of the evil hanyō by destroying large amounts of Naraku's body.

The Epilogue
Three years after the defeat of Naraku, Sesshōmaru visited Rin who was under the care of Kaede with gifts, and was annoyed when Kagome called him "big brother."

Physical description
Sesshōmaru appeared handsome and frail-looking at the same time, appearing as a tall and slender young man. He had fair skin with pointy ears, golden eyes with slit pupils, and waist-length white hair with short bangs. He had a crescent moon on his forehead that could be seen beneath his bangs, two stripes on each cheek, and a magenta stripe on each eyelid. When he used his Dakkoso, three stripes appeared on his wrists. Sesshōmaru's true form was a giant white dog with markings similar to the ones he had in his human form. His eyes became red with blue irises, the yōkai marks on his body widened and became more apparent, the stripes on his cheeks which were usually smooth became jagged and changed into a somewhat fiercer color, and his mokomoko wrapped around his body and extended into his tail. He only fully transformed to his yōkai form three times: once during a battle with Inuyasha, resulting in the loss of his left arm, again when he met his mother, and during the battle against Magatsuhi.
 * Humanoid form
 * Yōkai form

Outfit
Sesshōmaru's armor included a spiked pauldron that covered his left shoulder attached to the upper section of his cuirass and "lotus petal" faulds. When damaged, the armor automatically regenerated itself using yōki. Both his armor and his long flowing sash had a decided Chinese influence, as opposed to the customary Japanese armor and obi. His kimono was mostly white with a red and white cherry blossom flower crest at the collar and sleeves, showing that he was of royal birth. He wore sashinuki hakama which were gathered at the ankles, producing a "ballooning" effect. His footwear consisted of black ankle-high boots, also reminiscent of Chinese influence. On his right shoulder was his mokomoko-sama, the fur and tail of his true form which he retained in his humanoid form.

In the third movie, it was seen in his younger years, Sesshōmaru wore a slightly different outfit. His kimono was cream colored and had leaf patterns, and he wore a blue sash belt.

Personality
Sesshōmaru, born of a great demon bloodline, possessed the perfect power that many demons desired. Because of this, he was always composed and confident in his power.

His air of aloofness and indifference was a product of dignity that only one of such rare demonic power could possess. Sesshōmaru was more or less emotionless, with only anger, annoyance, and dissatisfaction showing on his face. Because both his heart and body were so strong, he had no desire whatsoever to own the Sacred Jewel, nor to conspire with allies. Sesshōmaru even responded sarcastically towards Naraku, who had assumed an air of impudence due to his increased demonic power. In battle, he judged his enemy's power level and attacked with the minimum power necessary. He dealt with his enemies after determining their power. Once he had realized their weak point, their attacks were futile.

Sesshōmaru was obsessively proud of his father, the Inu no Taishō, of whom the whole demon world was in awe. Because he respected his bloodline so much, he despised Inuyasha as well as Inuyasha's human mother Izayoi. He insulted Naraku, who tried to take advantage of Sesshōmaru's power. Anger welled up in his heart for not being able to use Tenseiga, the dull sword that wouldn't cut anything which was left by his father, whom he highly respected. Sesshōmaru held resentment towards his father for having left Tessaiga to Inuyasha, whose power was weaker than his own. However, over time, Sesshōmaru came to grasp why his father gave him Tenseiga, and let go of his disgust towards his half-brother, even showing concern for him in rare moments. He was also secretly angry that Naraku, who was assembled by demons far lower in level than himself, used abusive language and disrespect towards him. Sesshōmaru had stated that he seeked to only fight the strongest beings alive and how he had wanted to fight his father and defeat him. Sesshōmaru's love for his father was so great that even though he inherited the (at the time) worthless Tenseiga, he kept it around him for sentimental value. During the brief period Tenseiga was stolen from him in the third movie, he stated Tenseiga was not a sword he would miss if he lost it, if not for his father.

Sesshōmaru felt nothing for others, sneering and dismissing human feelings. Anyone in his way was an enemy whom he would exterminate without hesitation. He did not hold back his power, even against women. He rationalized that all his prey was the same, and defeated them accordingly. For one with such pride in his power, cooperation was proof of weakness, and being alone was a condition for the strong. Once he judged someone as an obstacle, he was quick to kill without hesitation.

He used to feel nothing for anyone, but meeting various people, such as the ever-changing Inuyasha, Naraku with his numerous proposals, and all-alone Rin, had brought change to his heart. After he saved Rin and became a true owner of Tenseiga, he started to show feelings behind his heartless and cruel words. He stopped the demonic Inuyasha's wildness by controlling his power, and he looked at him like an older brother reprimanding a younger brother, though he claimed he would kill Inuyasha, despite his actions showing the opposite. He even refrained from killing Kohaku when he could easily do so, when he looked in his eyes and saw emptiness and that he had given up everything.

Sesshōmaru had a very inquiring mind when there was something he cared about, but at the same time, he had almost no tenacity of purpose. If he became interested in something else, he would arbitrarily turn his back on what he was doing, even during battle. Just like his fighting style, he was quick to make decisions and act on them immediately.

The encounter with Rin awakened him as the true user of Tenseiga. The smile and fleeting life of this young girl who tried to save him caused Sesshōmaru to change for the first time. The will of his father, who cared for humans, had finally been passed to his oldest son. Sesshōmaru used to leave anything behind that might bind him, but he slowly but surely changed. Sesshōmaru genuinely cared about Rin and Jaken, and while he rarely showed it, he did appreciate their loyalty. Sesshōmaru originally held much contempt towards protecting the weak, seeing it as a ridiculous waste of time. Unlike the Inu no Taishō and Inuyasha, Sesshōmaru had trouble admitting he had people to protect (Rin and Jaken), and out of pride, would never admit that he did, as shown in the third movie. Another trait of Sesshōmaru was one he shares with his younger brother: having a temper and being very easy to annoy (Inuyasha being loud in his anger, Sesshōmaru being subtle), as he had been known to hit Jaken when he said something that displeased him, similar to how Inuyasha was with Shippō.

Growing Compassion
Sesshōmaru, who previously was a cold-hearted, arrogant, and extremely powerful daiyōkai, was humbled by his "worthless half-breed" brother, Inuyasha, who used Tessaiga to cut off his left arm. In another incident, Sesshōmaru had used his poison claws against Inuyasha, temporarily blinding him. Having sensed the clashing of the two yōki, Inuyasha unknowingly used the Wind Scar against Sesshōmaru. Tenseiga prevented a possible fatality, and transported the daiyōkai's battered body to safety. Sesshōmaru quickly rested for the time being in a forest near a village, where he first met the orphan girl, Rin.

He was cared for by Rin during his rehabilitation from injury. He was initially hostile to the mute girl, who offered him food, by refusing to eat and telling her to "mind her own business." However, the little child continued to serve him. Once he recovered, he set off with Jaken, but he sensed Rin's blood scent when she was attacked and mauled by Kōga's wolves; he was initially going to ignore her, but when Tenseiga pulsed and told him to save her, he used Tenseiga to resurrect her, whereupon she began to follow him. This incident proved to be the turning point in his life, as it dramatically transformed his attitude towards everyone else. This was apparent when Rin was later seen wearing a new and colorful kimono. When Rin fell off to the cliff in the process of getting life-saving herbs for Jaken, Sesshōmaru came in a bolt of light to save her after she called out his name. In the very same episode, Sesshōmaru claimed to have held back on Inuyasha in the past, which was proven true when he easily defeated Inuyasha to get information on Naraku's whereabouts. In Forever With Lord Sesshōmaru, after Sesshōmaru saved Rin, he asked Rin to do what she wishes. This was not at all typical of Sesshōmaru, as he was usually shown to leave Jaken at times before he met Rin. Jaken was even shown to be mumbling that "Lord Sesshōmaru will kill him if something happens to Rin", obviously showing his concern for the girl's safety. Sesshōmaru, while fighting Jakotsu, rushed off to rescue Rin, who fell when the bridge broke. Jakotsu noted that Rin was Sesshōmaru's weak point. Exploiting this fact, Suikotsu and Jakotsu threatened to kill Rin when they were cornered. Sesshōmaru even saved Kohaku, Rin's best friend and protector, who was under Naraku's control, under the behest of Inuyasha and his friends.

Sesshōmaru's compassion for Rin was evident, but he preferred to disguise it, because it would taint his pride. However, he showed his love and concern for Rin when she appeared to be dead due to her time in Hell. Sesshōmaru entered Hell for the purpose of rescuing her, but upon learning that he couldn't save her life, he was crushed. When he realized that it was his urge to strengthen Tenseiga which brought them to Hell and ultimately killed her, he cast the sword aside, saying that for the sword to gain power at the expense of Rin's life meant nothing. However, when Sesshōmaru's mother revived Rin, he was very relieved. Finally, the will of his father, who cared for humans, had been passed on to his son.

When Kagura was injured, Sesshōmaru originally intended to leave her in the river she was drowning in, but when Rin fell in trying to save her and Jaken followed Rin, Sesshōmaru pulled all three from the river. He stayed there afterwards, and warned Kagura not to do anything that would get her killed. Later however, before Kagura's death, Sesshōmaru sought her out and considered using Tenseiga, only to conclude that Tenseiga couldn't save her.

He had also been shown saving Inuyasha's friends on several occasions. On his way to Mount Hakurei, Sesshōmaru saved Kagome, Miroku, and Sango from the poison master Mukotsu, one of the Shichinintai, but only claimed that he killed Mukotsu because he would not answer his questions. He also revived a young otter yōkai's father, claiming that it was the will of Tenseiga. Another example was when Inuyasha and his companions were involved in a fight with the "water god" Numawatari; when Sesshōmaru arrived, he insulted Inuyasha's inability to kill a "low life demon", and then easily dispatched Numawatari using his Meidō Zangetsuha ability, leaving straight after.

Also, when Byakuya, Naraku's newest incarnation, was about to take Kohaku, who had one of the last three shards of the Sacred Jewel, back to Naraku, Sesshōmaru appeared and launched a ranged Meidō Zangetsuha (still in the crescent moon shape), barely missing him. Byakuya fled, claiming that he did not want to die, and commented on how it was so unlike Sesshōmaru to save someone. Thereafter, Sesshōmaru seemed to have taken Kohaku under his protection, albeit in his typical grudging demon-slayer fashion. Later, when Kohaku's shard was tainted by Magatsuhi, Sesshōmaru attempted to save Kohaku at the expense of great injury to his arm.

It was his compassion that caused Tenseiga to be reforged as a weapon. Its offensive powers were locked until Sesshōmaru was able to show true compassion. In his battle with Mōryōmaru, the villain insulted the dying Kagura, which angered Sesshōmaru, and he shattered Mōryōmaru's indestructible shell (and his only weapon in the process). Acknowledging the yōkai's growth because he was defending a dead person, Tenseiga called to its creator to reforge it as a weapon. Later, to show his compassion and respect for his father, he gave the offensive powers of his sword to Inuyasha (albeit in his typical fashion), in accordance with his father's wishes, recognizing his brother's worth as the heir to the sword.

He refused to use Bakusaiga on Inuyasha when even Magatsuhi noted it was the obvious choice to make, and in the third movie, it was hinted that he actually did care about Inuyasha but refused to admit it when he was protecting him from Sō’unga's "Dragon Twister" attack.

Despite his growing compassion, he, like his brother, used impolite Japanese. He addressed strangers or people he does not like with "kisama", which, like "temee", was an offensive form of "you", though still more formal. He addressed himself with the polite "watashi", signifying his high rank and power. Other than "kisama", he used "omae", either to Jaken or to Inuyasha, the latter being occasionally and not rarely. Thus, he could be insulting while retaining the dignified speech pattern of a lord, as opposed to the rougher speech used by Inuyasha.

Powers & Abilities
Master Swordsman: As Sesshōmaru wielded the most amount of demon swords in battle, he possessed a high caliber of swordsmanship, where in several occasions he was able to easily and consistently overwhelm his younger brother when they clashed their demonic swords. Even in the rare chance that Inuyasha managed to defeat Sesshōmaru, it was only after Sesshōmaru had held the upper hand and Inuyasha became accustomed to Sesshōmaru's skills. Despite Inuyasha developing his sword skills with Tessaiga to eventually match Sesshōmaru, the older demon was still superior, since he practiced his skills longer and to a greater degree than Inuyasha. Sesshōmaru's overall skill was such that he could wield the Tessaiga with equal or greater use than Inuyasha with just one hand, while the hanyō always wielded it with both hands.

Master Hand-to-Hand Combatant: Along with his swordsmanship, Sesshōmaru was also an accomplished unarmed fighter, being able to consistently outpace and overwhelm Inuyasha in hand-to-hand combat. Unlike Inuyasha, who repeatedly threw punches everywhere, Sesshōmaru attacked when he saw the perfect opportunity, thus displaying greater experience and skills. During their two battles before Sesshōmaru commissioned Kaijinbō to forge Tōkijin, the older demon was able to casually pressure Inuyasha wielding Tessaiga (before he learned the Kaze no Kizu). Also, during the third movie, it was shown that Sesshōmaru was able to fight adequately against the self-sustained body of So'unga with his bare hands and only one arm after Tōkijin was damaged by the greater demon sword, though Jaken noted that Sesshōmaru was still at an overall disadvantage.

Keen Intellect: Due to his long years of pursuing power, Sesshōmaru was very intelligent and experienced in the Feudal Era. He was able to come to the correct conclusion towards any given mystery in his quest of power once he attained the basic understanding of the situation. In the flashback of the third movie, Sesshōmaru was able to correctly deduce that his father was testing him when asked if he had someone to protect, but denied it due to his pride. By having the Unmother lure Inuyasha into an illusion of his real mother, Sesshōmaru eventually figured out that the black pearl was hidden in Inuyasha's right eye. Once he was told of Tenseiga's true nature as a cast off of Tessaiga to contain the Meidō Zangetsuha, Sesshōmaru immediately deduced the correct conclusion that the Inu no Taishō intended for Sesshōmaru to master the technique before giving it to Inuyasha. Eventually, after seeing how Magatsuhi survive a decapitation by his true form, Sesshōmaru deduced that the demon was a spirit possessing Naraku's flesh, and struck it with Tenseiga. Despite Sesshōmaru's above average intellect, he was exceedingly arrogant, and had been known to chronically underestimate his opponents. This problem had put him in numerous potentially lethal situations despite his tremendous power. His mother pointed out at one point that he was still naïve despite his age.

Immense Demonic Power: As the full blooded son of the Great Dog Demon, Sesshōmaru is overwhelmingly powerful, being a match for any opponent he encounters. He has exhibited senses much more powerful than that of humans and even many demons and a plethora of powerful techniques at his disposal. Even the arrogant Naraku, who became famous amongst demons through his collection of the Shikon Jewel Shards, acknowledged Sesshomaru to be far more powerful than himself and stated the Sesshomaru is the perfect demon. It is because of the perfect combination of his powers that he inherited from both of his parents that the Shikon Jewel wouldn't increase his overall power which is why he doesn't have the slightest interest of obtaining even one shard of the jewel and is completely confident in his own powers. The level of his demonic powers are such that he was able to easily subdue the malevolent demonic aura of Tokijin created from Goshinki's hatred when Kaijinbo, the creator of the sword, was possessed and consumed by it. Eventually Sesshomaru's powers surpasses that of his father after he abandoned his obsession for Tessaiga thus becoming one of the most powerful, if not, then the most powerful demon at the end of the series.


 * Immunity: Sesshōmaru's tremendous demonic powers has granted him great resistance to injury over the course of the series. He has been shown to be able to resist deadly diseases, gases and toxins that affect humans and weaker yōkai quite easily. He has also demonstrated a great deal of resistance to holy or spiritual energies, as demonstrated by the fact that he was able to enter Mt. Hakurei's purification barrier, by far the strongest of its type in the series, without being purified. In another instance, Sesshōmaru caught one of Kagome’s purification arrows barehanded and to no ill-effect; any other demon would have been severely injured, if not outright purified (though this occurrence was limited to the anime). Even holy attacks coming from multiple trained and powerful monks (like Ungai and his men) had absolutely no effect on Sesshomaru. Sesshōmaru is said to be "unaffected by human attacks" according to Inuyasha.

Flight: Sesshōmaru is capable of independent flight or can extend his mokomoko-sama and use it to carry himself through the air. The latter method of flight enables him to bring others along with him while flying by riding his mokomoko-sama with him.

Immense Speed: Sesshōmaru can move faster than the human eye can perceive, both on land and in the air. Although, Sesshōmaru's top speed is never disclosed in the anime or manga it is known that he can move incredibly fast without much exertion. Sesshōmaru is at least capable of moving quickly enough to leave afterimages in the anime and blurs in the manga. He can also instantaneously close long distances without being detected by others. Also during their many battles over Tessaiga, Inuyasha always showed incredible difficulty in keeping track of Sesshōmaru's movements despite his own great speed.

Enhanced Strength: Sesshōmaru possesses physical strength far beyond that of a normal demon. His strength with only one arm is equal to Inuyasha’s full strength; Inuyasha’s strength allows him to lift a 9 to 10 ton boulder using one arm with little effort, so Sesshōmaru is likely capable of lifting double that amount of weight. Sesshomaru is shown capable of easily crushing apart boulders and can tear through the bodies most demons with ease with his claws alone.

Immense Endurance: On the fairly rare occasion that he receives serious injuries, Sesshomaru can often continue fighting in spite of them. This was demonstrated when he was able to easily kill an army of human samurai just after losing his left arm and initial battle over the Tessaiga to Inuyasha. Later on Sesshomaru managed to withstand the Kaze no Kizu head-on for some time before Tenseiga used its barrier ability to protect Sesshomaru from the lethal damage level of the attack. Depsite being heavily wounded during his battle with Magatsuhi, Sesshōmaru was able to continue fighting until his powers coalesced into Bakusaiga. Sesshomaru is also shown to be able to withstand the shock of the Anti-Demon Barrier placed on Tessaiga in order to use occasionally when need be with little reaction, though not without suffering potentially debilitating injuries.

Enhanced Senses: Due to his lineage, Sesshōmaru exhibits extremely heightened senses, particularly his sense of smell. He can discern characteristics of most objects through scent, such as the undead Band of Seven through the scent of graveyard soil and pure-demon blood from half-demon blood (such as when Inuyasha's demon blood takes over). Through smell alone, Sesshōmaru can follow events transpiring far away or which have already transpired; for example, he learned of everything that had happened during Inuyasha's confrontation with Goshinki by simply sniffing the area in which they fought at least several hours, if not days, after the battle.

Transformation: As a Daiyokai, Sesshomaru possesses the ability to transform depending on what the circumstance are with his usual form being that of a white haired humanoid during which is when he interacts with most and can also transform into other forms as well.
 * True Daiyokai Form: While he appears to be an elf-eared human bearing splendid clothing and armor most of the time, he can transform into his true inuyōkai form. He transforms into this form by channeling all of his demonic powers outward that creates a whirlwind of Yoki around himself and the sclera of his eyes turn red before his form shifts into that of a giant white dog. Though this form appears to grant him a great deal of strength, he tends not to use it in battle as it seems to lack the agility of his humanoid form, in addition to having limited defensive capabilities (as he cannot use any weapons while transformed). When transforming back and forth, his clothing, weapons, and other accouterments seem to simply vanish and then re-appear on his person. Additionally, it was speculated by Jaken that Sesshomaru loses some of his reasoning abilities while in his form (though there is no direct evidence to prove this).
 * Flight: Sesshomaru is capable of flying in this form as well and can even do so while transforming.
 * Psionics: While transforming into his true form, his demonic aura can telekinetically manipulate the surrounding objects as in "Showdown: Inuyasha vs Sesshomaru", he was able to levitate and hurl skulls at Inuyasha and Kagome.
 * Immense Strength: While in this form, Sesshōmaru's strength becomes even greater with his stomps and simple attacks possessing devastating effect. When he first used this against Inuyasha when his brother first claimed the Tessaiga, he was able to demolish parts of his father's giant corpse by simply pushing through it and later ripped apart Magatsuhi's physical form from Naraku's flesh when his human form could do little damage to it.
 * Enhanced Speed: Despite the large size of his true form, Sesshōmaru possesses astounding speed for an enormous dog where Inuyasha had a hard time dodging some his attacks during their first battle over Tessaiga despite being more agile. When he transformed in order to fight against Magatsuhi, Sesshōmaru was able to bite off and decapitate the demon spirit's physical form's head before he could react when the dog demon took him by surprise.
 * Enhanced Durability: While in his true form, Sesshōmaru has greater physical might where even after having his left arm cut off by Inuyasha, he still has the strength to continue fighting while ignoring the pain and damage. Even after Inuyasha slashed him twice at his torso to end the battle, Sesshōmaru was able to transform himself into an orb of light to escape. However, this form's durability is extremely limited compared to many of the demons that appear later in the series, as Inuyasha was able to cut off it's left foreleg after having only just figured out how to wield Tessaiga's most basic powers. Overall, transforming appears to give him no additional durability, but it does not detract from it either.
 * Dokkasō: While in his transformed state, the toxins of Sesshōmaru's poison claws are transferred into his fangs. This caused his bite to have extremely caustic effects, an ability which is also transferred to his saliva. Additionally, his saliva can be turned into a poisonous, mist-like gas.

Immortality: As a daiyōkai, Sesshōmaru has an extremely long lifespan. He appears to be physically around 19 years old despite being chronologically over 200 years old.
 * Light Orb Form: Sesshomaru can also transform into an orb of light for escape when necessary and for quick pursuit of his target. This form is achieved by either being in his true form or his human form whereas it if it was his true form then his body would curl up into a ball and he would shift into this form.
 * Flight: While in this light orb form, Sesshomaru can fly faster than either his human or true form can as it acts for a quick escape or quick pursuit.
 * Teleportation: This form also gives Sesshomaru the ability teleport away if so necessary as in "Showdown: Inuyasha vs Sesshomaru", Sesshōmaru morphed into a ball of energy to escape his father's grave. He later uses this form in Tetsusaiga and Tenseiga to pursue a fleeing Tōtōsai, materializing upon impacting with the ground and producing an explosion.

High-Speed Regeneration: During his battle with Magatsuhi, Sesshōmaru's demonstrated the ability to heal the burns and gashes on his right arm, as well as several large holes stabbed right through his body. This ability seems not to be a passive bodily function however, as he evidently needed to focus his energies in order to heal himself. In the same battle, he was able to restore his left arm, which was cut off by Inuyasha at the beginning of the series. Why it took so long for this to occur is a matter of speculation, and it is not known whether or not his ability to regenerate his arm was simply a one-off power that accompanied the creation of Bakusaiga. Dokkasō (毒華爪, Toxic Luster Claw): Sesshōmaru can release an acidic poison from his claws that can liquify flesh and bone upon contact. Though he normally applies it through his claw strikes, he can also spray the acid from his claws or transfer it into his punches. The acidic effect also has the ability to blind his targets temporarily if they manage to resist it. Mokomoko-sama (モコモコ様, lit. Lord Fluff-Fluff): The fur on Sesshōmaru's shoulder can be extended to great lengths and used to whip, constrict and fling his opponents or carry himself through the air. However, because it is a part of his body, the mokomoko-sama seems to be capable of bleeding and seems to be highly sensitive to pain, to the point that injuring it can temporarily incapacitate him. This is not known for certain however, as the circumstances during which this injury occurred were rather vague; the Mokomoko may not have been bleeding during this instance as Sesshōmaru's shoulder had also been injured and was bleeding heavily at the time.
 * Poison Resistance: A sub-effect of his poison claws is that he is highly resistant to both environmental toxins and poison-based attacks. For instance, Naraku's post-Mt. Hakurei miasma had no effect on Sesshomaru despite being able to melt rocks. Even poisons that are specifically designed to destroy demons like the specialized anti-demon poison created by Mukotsu of The Band of Seven proved to be ineffective against Sesshomaru. However this resistance is not absolute, as the miasma of the demon spirit of the Shikon Jewel, Magatsuhi, was able to severely burn Sesshomaru on contact.

Poison Whip: Sesshōmaru can generate a thin, whip-like strand of yellow-green energy from his fingertips to aid him in place of his missing arm. It has shown to be able to puncture armor and flesh with ease and can burn flesh upon contact, similar to his poison. He appears to be capable of manifesting this energy without its destructive properties, allowing him to use it to catch falling allies or yank someone out of danger without damaging them. However, this ability is exclusive to the anime.

Weapons
Regenerating Armor: Sesshomaru wears a form of armor over his kimono that can supposedly regenerate itself over time if it was ever damaged in battle. This is shown when Inuyasha broke it during their initial battle over Tessaiga within their father's corpse and after the battle, Sesshomaru is shown wearing the armor perfectly intact when he faced against the samurai army despite not having made any attempts at repairing or replacing the damaged portion. Tenseiga: The Tenseiga is the second sword created by Totosai using the Great Dog Demon's fang. This sword is created for the purpose of healing and resurrection and was given to Sesshomaru in an attempt to teach him compassion and empathy. The sword is the first weapon Sesshomaru received and eventually he came to value it as even after obtaining Bakusaiga, which is his own signature weapon with greater power than the Tessaiga, he still kept this sword. The sword emits a blue aura when in use and possesses its own will that Sesshomaru can sense.
 * Spiritual Cut: The most basic ability of this sword is that it has power cut spiritual entities where it can destroy beings not of the living world. In the third movie, this sword was able to easily slash through Takemaru (whom have been resurrected by Sounga) and the reanimated human was only able to recover because of Sounga. Later on this sword became an instrumental weapon in defeating Magatsuhi, the evil will of the Shikon Jewel, because it can also cut souls as well. A side effect of having this ability is that Tenseiga is unable to harm living beings.
 * Resurrection: Through the ability to cut spiritual beings, Tenseiga can resurrect the dead. It does this by letting Sesshōmaru see the pall-bearer imps that take away the souls of the dead so that he may destroy them with Tenseiga. Though this ability only works once on a certain individual because its ability to resurrect is not absolute and thus there will be no pall-bearer imps appearing around the target of resurrection if they were revived by Tenseiga before. In order for the Tenseiga to call back a soul, it must be able to return to its body. Since Kagura's body was being dissolved by Naraku's miasma, Sesshōmaru realized that not even the Tenseiga could save her, as she would have no body to return to.
 * Purification: Tenseiga is also said to be able to resurrect 100 dead individuals at once by releasing an enormous pillar of light.
 * Protective Barrier: In extreme cases, the Tenseiga also protects Sesshōmaru from potentially lethal attacks by emitting a black mist-like barrier when he faces an attack too lethal for him to endure on his own. The protective barrier is capable of blocking the Kaze no Kizu from the Tessaiga and the Gokuryuuha from the Sounga though not completely as both attacks managed to still harm Sesshomaru to a certain extent.
 * Sapience: Tenseiga appears to have limited sapience, and can be seen to occasionally give Sesshomaru hints during situations where he is at a loss for what to do. These instances usually involve either indirect advice during difficult battles or nudging Sesshomaru towards actions that allow him to grow as a person.
 * Soryuha (蒼龍破,Pale Dragon Blast; "Dragon Strike" in the English Dub): This is Sesshōmaru's signature attack while he possessed Tokijin. Because this is born from Sesshōmaru's own demonic powers instead of a demon sword he can also use this with Tenseiga when it was originally used in Tokijin in the third movie. However, this ability was never seen outside of the movies.
 * Meido Zangetsuha (Former): Later in the series, the Tenseiga is reforged by Tōtōsai to become a weapon, allowing Sesshōmaru to use the Meidō Zangetsuha. It is later revealed that the ability and the sword itself is merely a cast off of the Tessaiga; his father wanted Sesshōmaru to master the Meidō Zangetsuha. Sesshōmaru becomes quite angered because of this, but eventually Sesshōmaru discards the sword as his father wished, giving the ability back to the Tessaiga and making the Tenseiga only a healing sword once again. Shishinki, the original wielder of this technique, stated that because Tenseiga was only a cast off of Tessaiga to contain Meido Zangetsuha, it is incapable of producing a complete Meido on its own and thus needed to resonate with Tessaiga to do so.
 * Tessaiga Replication (Temporary): By crushing a fragment of Kanna's mirror obtained from Byakuya under Naraku's order onto Tenseiga's blade, Sesshomaru can have it copy and steal the forms and abilities of Tessaiga. Though this is temporary as once the Tessaiga clashes with Tenseiga eventually the stolen abilities are returned to the original sword. Naraku is able to possess this form of the Tenseiga due to having Kanna's mirror fragment spread over the blade. Sesshomaru did this for the purpose of seeing if Inuyasha could handle the Meido Zangetsuha and when he does, the dog daiyokai finally relinquished it to him.
 * Fang Form: Once Sesshomaru has the Tenseiga reflect the Tessaiga using the mirror fragments of Kanna, the blade takes the same form as Tessaiga's ordinary fang form.
 * Kaze no Kizu: By slashing the demonic vortex, Sesshomaru is capable of producing an enormous energy slash capable of taking out a hundred demons in one sweep.
 * Bakuryūha: By cutting at the vortex of a Yoki attack made his opponent, Sesshomaru is capable of reflecting it back at them with the added power of the Kaze no Kizu combined so long as his demonic powers are greater than his opponent's.
 * Red Tessaiga Form: When Inuyasha uses the sheath of Tessaiga to block the Adamant Barrage, Sesshomaru has the Tessaiga take the color of red in order to use its new barrier breaking ability.
 * Barrier Shattering: The main ability of this form is that it is made to break demonic barriers that normal attacks can't. While in Sesshomaru's hands it was capable of breaking the barrier created by Tessaiga's sheath which was strong enough to block the Adamant Barrage.
 * Diamond Tessaiga Form: Sesshomaru first attacked Inuyasha with the copied Tessaiga in this form. Inuyasha resolved to re-obtain this ability after regaining the Bakuryuha from an earlier clash.
 * Adamant Barrage: This technique fires off a barrage of diamonds at the opponent with enough power to destroy almost any barriers. Though despite the considerable power, Inuyasha managed to block it using the the Tessaiga's sheath.

Tessaiga (Occasionally): The Tessaiga is the first sword created by Tōtōsai using the Great Dog Demon's fang and is also the sword that Sesshomaru is obsessed with possessing. He believes his father is to be the greatest demon and thus wished to defeat him to claim Tessaiga for himself one day. However his father placed a barrier on the sword to prevent Sesshomaru from being able to wield it harmlessly. Despite this during the rare occasion that Sesshomaru manages to get a hold of Tessaiga, he was able to wield its powers quite proficiently while ignoring the damage caused to his hands. In the third movie, he managed to use the weapons against a Sounga-posessed Inuyasha, firing off a Kaze no Kizu. However, doing so burned him to the point where he was temporarily incapacitated.

Tōkijin (Former): Tōkijin was a sword crafted by the evil sword smith Kaijinbō from the fangs of Goshinki as part of Sesshōmaru's continued efforts to obtain Tessaiga or a sword matching it in power. It is shown to capable of matching Tessaiga in power as the fangs of Goshinki were capable of breaking the original Tessaiga before being reforged by Totosai using Inuyasha's fang. Eventually in Sesshomaru's battle against Moryomaru, he broke it while attempting to penetrate the demon's absorbed shell. Sesshomaru refused to repair it because it did not have the power to defeat Moryomaru and resolved to find a replacement sword.
 * Immense Demonic Aura: Due to Sesshomaru having to revive Goshinki's head before Kaijinbo forged the fangs into Tokijin, the demon sword possesses an intense demonic aura of hatred from Goshinki that was strong enough to possess Kaijinbo and eventually consumed him when he wasn't strong enough to withstand it. When Sesshomaru claimed that Tokijin himself, he was able to subdue the aura with his own.
 * Energy Attacks: It can fire off extremely powerful blasts of pure evil energy, but because it is filled with Goshinki's malice, only someone with a very powerful demonic presence can wield it without being controlled by it. The energy blasts created by Tokijin takes on multiple forms due to Sesshōmaru developing it further on his quest for power.
 * Needle Energy Blast: Originally the energy blasts of Tokijin took the form of needles that Sesshomaru fires off the tip of the sword without having to slash it.
 * Blue Energy Wave: Later on Sesshomaru develop it to fire off the energy waves blue in color similar to the Kaze no Kizu and is seen capable of rivalling it in power.
 * Green Energy Sphere: Finally Sesshomaru has it take on the form of energy spheres green in color and can be fired off at high speeds.
 * Soryuha (蒼龍破,Pale Dragon Blast; "Dragon Strike" in the English Dub): Like Tenseiga, it can perform Sōryūha; however, being "only an Oni's fang", Tōkijin initially could not withstand repeated uses of Sōryūha the way that Tenseiga could. But later, in the 4th InuYasha movie, Tōkijin seemed to be capable of being a conduit for the attack with no ensuing refractory period. The first form of the attack when used by Tokijin are streams of blue lightning and eventually a lightning dragon. Sesshomaru can even channel it into the ground to break through an opponent's barrier. This ability however, was limited to the movies.

Bakusaiga: Bakusaiga is Sesshōmaru's current signature weapon. The Bakusaiga manifested itself in the hand of Sesshōmaru's fully regenerated left arm during his battle with Magatsuhi. Its creation signified Sesshōmaru's graduation into a full-fledged daiyōkai, which was long compromised by his obsession with Tessaiga. Tōtōsai comments that his ability to manifest his own blade suggests his strength and power has surpassed that of his father's and connotes his growth through the many trials he endured to emerge as a daiyōkai, with the Bakusaiga serving as the product of this 'rite of passage'.
 * Decomposition: The energy produced by Bakusaiga has an extremely corrosive effect on organic matter, which lingers even after a blast from the weapon. For instance, Miroku commented at one point that, should Naraku attempt to absorb something that was killed by Bakusaiga, this caustic decomposition would be transferred from the corpse of whatever had been absorbed to Naraku.
 * Explosive Corrosion Wave: Sesshomaru can fire off the decomposition ability of Bakusaiga as an explosive energy wave that can slay thousands of demons in one slash. Though similar to the Kaze no Kizu, Rumiko Takahashi stated that Bakusaiga's yōki wave attack possesses much greater strength and power than a full power blast from Inuyasha's Bakuryūha.

Nintōjō (Never Used): also known as the "Staff of Two Heads", is the weapon which Jaken wields. It can produce long streams of flame, and generate large floods of water. For some reason, possibly one of the possessions left to him by his father, Sesshōmaru knew of where to find this weapon, and give it to his future ward, Jaken. It is with this that Jaken was able to help him track down the Tessaiga. The old man head can spew fire whenever Jaken wishes. When close to the grave of the Inu no Taishō, the old man's head laughs. But when at the wrong place, the woman shrieks.

Family
Aside from the fact that Sesshōmaru loathed humans and half-demons, Sesshōmaru despised Inuyasha not only because he wields the Tessaiga, is a half-demon and his half-brother, but also because he couldn't stand the fact that his father's demon blood courses through his veins. For almost the first half of the series, Sesshōmaru's hatred for Inuyasha seemed to stem at least in part from his strained relationship with his father; both from the fact that he was given the 'useless' Tenseiga instead of Tessaiga, and because of his failure to understand both of their affinities for humans. After much growth and reflection, Sesshōmaru eventually starts to care for Inuyasha, though he would never admit it. While Sesshōmaru continues to make rude comments towards Inuyasha, their relationship eventually improves, and they appear to look out for each other in battle, as shown when they join forces to battle against Naraku. By the end of the series, Sesshōmaru appeared to have more-or-less lost his antipathy for Inuyasha, and even decided to leave Rin in Kaede's village (which was Inuyasha's home) in order for her to re-integrate into human society. However, the two brothers still appear not to have any particular affection towards each other.
 * Inuyasha

His relationship with his father is distant and estranged due to the fact that his father had left his wife (Sesshōmaru's mother) and fallen in love with a mortal woman named Izayoi; who became the mother of his younger half-brother, Inuyasha. In InuYasha: Movie 3, Sesshōmaru only seems to want to gain power, something his father finds disappointing. Inu no Taishō asks him if he has someone to protect. Sesshōmaru knew this was his father's final test for him. He answers "no", finding the idea of protecting someone ridiculous. It seemed at that moment, he was ready to slay his father for not entrusting Tessaiga and Sō'unga to him. At the beginning of the series, Sesshōmaru despised humans and considered them as weak and useless. 200 years later, he would realize that his father's words would echo, because he did have someone to protect: his companions Rin and Jaken (and at times, his younger brother Inuyasha). During his battle against the Sō'unga with Inuyasha, Sesshōmaru is able to release an immense amount of power that along with his brother's attack aids in the destruction of the sword after recalling the numerous times he had protected Rin and Jaken, though he verbally exclaims that he protects no one.
 * Inu no Taishō

Only shown for a small amount of time, Sesshōmaru's mother's name is never stated. She is a full-yōkai who is devilishly similar to her son - the moon upon their forehead, their attitudes, and how they despise humans. When Sesshōmaru went to visit her, it was to make his power of Meidō Zangetsuha stronger and more mature. She knew he would come to do this seeing he was finally able to unlock the new power, thus stating that in order to do so, the power was to be exchanged with Rin's life. Her attitude changes from generous to irritated when Sesshōmaru ignores her offer to bring him before he was able to save Rin, making it seem she didn't care about him anymore. Even though she ignores the fact that Rin's a human, she still has motherly feelings toward Sesshōmaru. Concerned with her son's sadness, Sesshōmaru's mother resurrected Rin with the Meidō Stone. When Rin is revived, Jaken says she's an honorable mother for doing so. She asks Jaken if he's happy this way, and he says it's most likely extremely so. She later states, "All this fuss over one human girl... He's becoming like his father in the strangest ways," referring to his father's kindness to humans.
 * Sesshōmaru's mother

Traveling companions
Sesshōmaru encountered Jaken when he was passing through a distant land. A large demon was wreaking havoc amongst Jaken and other demons resembling him when Sesshōmaru killed the demon with his mere claws. Despite Jaken's display of immense gratitude, Sesshōmaru claimed he was only passing through. Sesshōmaru walked to a nearby waterfall and pulled out the Staff of Two Heads. He told Jaken that if he was able to wield the weapon, he may follow him. Jaken deeply respects and always praises Sesshōmaru, much to Sesshōmaru's annoyance. At times, he gets too carried away and winds up insulting Sesshōmaru, which usually leads to a couple bumps on the head. Jaken is condescending to all but Sesshōmaru. When Jaken belittles Rin, Sesshōmaru will usually yell at him and tell him to knock it off. Because Jaken is (reluctantly) aware of Sesshōmaru's compassion toward Rin, he knows that he, too, must responsibly protect her or else face the wrath of his master.
 * Jaken

Rin is a young orphan who becomes the traveling companion of Sesshōmaru and Jaken. When Sesshōmaru was injured by the Wind Scar after trying to steal the Tessaiga again from Inuyasha, Rin bravely attempted to care for him as he lay near a tree, bringing him water and food. Sesshōmaru initially rejected her kindness, telling her generosity was a waste, as he does not eat human food. She continues to bring him things and he is caught off guard by her smile. After letting his wolf pack hunt, Kōga's wolves killed Rin. Sesshōmaru, recognizing the scent of Rin's blood, stumbled upon her dead body in the forest. He was initially going to ignore her, but the image of her smile flashed in his mind, he unsheathed Tenseiga and it began to pulsate. He then saw the beings of the underworld surround Rin's body and decided to resurrect her with the Tenseiga as a "test". To his surprise, her heart began to beat again and she is revived. From that day forward, she would be by Sesshōmaru's side along with Jaken and a two-headed dragon demon known as A-Un.
 * Rin

Throughout the series, Rin's warmness and kindness play a significant role on Sesshōmaru. His growing compassion for her allows him to advance in battle. He constantly rescues her and looks out for her despite claiming he did not care for her. He often instructs her to stay in a safe place with A-Un when he knows he is going somewhere dangerous. He often avoids killing in front of her, unless it is the only way to protect her. In The Final Act, Sesshōmaru wished to improve his Meidō Zangetsuha technique but it unfortunately came at the cost of Rin's life. He finally felt sorrow from the loss of his beloved companion. Concerned with her son's sadness, Sesshōmaru's mother resurrected Rin with the Meidō Stone.

Following Naraku's defeat and after some input by Kaede, Sesshōmaru agrees that Rin needs to reside in a village to get used to living with humans once again and where she is safe from potential harm. When the time comes, Rin will decide whether to stay in the village or go with Sesshōmaru. He continues to pay her regular visits often bringing presents with him, she is last seen receiving a kimono from him.

Naraku abducted Rin by using Kagura and had Kohaku serve as her guard. After seriously injured by Sesshōmaru and Inuyasha at his castle, Naraku had fled and ordered Kohaku to kill Rin. Mind-controlled, Kohaku was ready to kill Rin but Sesshōmaru arrived at the scene, deciding not to kill Kohaku, knowing that was what Naraku wanted him to do and he does not play by Naraku's rules. After Kikyō died, Kohaku decided to follow Sesshōmaru, who didn't seem to be against the idea, and Sesshōmaru also begins to protect him too. Kohaku forms a great friendship with Rin and protects her in times of trouble. In his battle with Magatsuhi, Kohaku attempts to protect Sesshōmaru. Eventually, Kohaku would part with Sesshōmaru and remain with his sister, Sango, and the rest of Inuyasha's gang prior to the battle with Naraku, where he would then leave with Jaken and Shippō to fight.
 * Kohaku

A-Un was a two-headed dragon yōkai who traveled by Lord Sesshōmaru's side for a long time. He was Sesshōmaru's first 'traveling companion' and was always loyal to his master. A-Un always cared for and protected Rin whenever Sesshōmaru left his companions for a while.
 * A-Un

Enemies
Naraku has been seen a few times throughout the series trying to use Sesshōmaru to kill Inuyasha for him. The first time was when Naraku offered Sesshōmaru the human arm with the shard of the Shikon Jewel in it, along with the hive of poisonous insects that would block Miroku's wind tunnel. After Sesshōmaru disposed of the sacred jewel shard he confronted Naraku. And at the end of the confrontation Naraku spoke of how he might call on Sesshōmaru again if a chance shall arise to kill Inuyasha. This of course hurt Sesshōmaru's pride, being used by a half demon like Naraku. But Naraku and Sesshōmaru become real enemies when Naraku orders his incarnation Kagura to abduct Rin. He then tells Sesshōmaru that if he heeds his request he shall return Rin in good health. This of course insults Sesshōmaru's pride even further. Sesshōmaru rips off the head of the demon puppet and heads towards Naraku's castle. Naraku and Sesshōmaru start to fight at the castle and Naraku attempts to absorb Sesshōmaru into his body. But his attempt is thwarted by Inuyasha who breaks Sesshōmaru free. Inuyasha and Sesshōmaru then severely injure Naraku and he gets away by using Kohaku and telling Kohaku to kill Rin. Sesshōmaru then rescues Rin and begins to pursue Naraku to get back at him for not only insulting his pride but abducting Rin as well.
 * Naraku

Then Sesshōmaru tracks Naraku all the way to Mount Hakurei where they meet moments after Kikyō falls into the river of miasma. Naraku tests his power against Sesshōmaru and retreats. Sesshōmaru then keeps learning more and more about Naraku's heart. He almost destroys Naraku's heart which was hidden inside the infant that was left with Kanna. But Kanna escapes with the infant. The infant then creates itself a shield using parts of different demons and humans. The infant's shield is named Mōryōmaru. After Kagura dies, Sesshōmaru accepts the fighting Tenseiga to destroy Naraku in order to make sure that she hadn't died in vain. Sesshōmaru then obtains Bakusaiga which allows him to help Inuyasha and the others destroy Naraku.

At first, Sesshōmaru appeared to be annoyed with Kagura's constant appearances because he felt as though he had no obligation to be "used" to fight Naraku so that she could be free. Eventually, her visits would be useful as she provided him with information on Naraku's whereabouts.
 * Kagura

After getting injured by Goryōmaru's light cannons, she falls into a river near Sesshōmaru. Initially, he rejects Jaken and Rin's proposal of helping her but after both of his companions fall into the water in an attempt to save her, he saves all three of them. He stayed with her afterwards and warned her not to do anything that would get her killed. It is hinted that Kagura had romantic feelings for Sesshōmaru, as she landed in the spot that she did to see him "one last time before she died."

When fighting against Mōryōmaru, both he and Sesshōmaru pick up on the scent of Kagura's blood. Mōryōmaru laughs and jokes about how Kagura will have died in vain. This notion angers Sesshōmaru and he breaks Tokijin while attacking Moryoumaru; it also gives him the energy to break free from Mōryōmaru's grasp. After Mōryōmaru flees, Sesshōmaru finds Kagura, who is slowly dying in a field of flowers as a result of Naraku's miasma. Feeling as though it is too good to be true, Kagura asks Sesshōmaru if he thought he would find Naraku there but Sesshōmaru responds that he knew it was Kagura. After hearing this, Kagura was able to die in peace, knowing that in that instant, Sesshōmaru had cared about her well-being. While it is unknown as to whether or not Kagura's feelings for him were unrequited, Sesshōmaru's concern for her after smelling her blood in battle with Mōryōmaru triggered his Tenseiga to become ready to be forged into a weapon. During his battle with Mōryōmaru, he became noticeably angry when Mōryōmaru insulted her memory. Tōtōsai explains that something in Sesshōmaru's heart had changed as he felt the sorrow and anger of losing someone. After learning the Meidō Zangetsuha for the first time, a breeze blows and Sesshōmaru decides that he, Sesshōmaru, will decide whether or not Kagura died in vain.

Other
Bokusenō is the only one of the Inu no Taishō's former friends that actually gets along with Sesshōmaru. Bokusenō is therefore the only one that Sesshōmaru can ask for information about his father's swords, as both Tōtōsai and Myōga are much too afraid to meet with him. Whenever Sesshōmaru encounters Tōtōsai, Sesshōmaru usually ends up threatening his life or attempting to kill him when Tōtōsai refuses to cooperate with him. However, when he is with Bokusenō, Sesshōmaru treats the tree with respect and drops his normal haughty tone with which he usually speaks to people. Bokusenō holds Sesshōmaru's powers in high esteem and agrees with Sesshōmaru when the latter states dismissively that it would be impossible for him to ever to be cornered in a desperate situation. It would appear as if Sesshōmaru meets with Bokusenō frequently, as Tōtōsai deciding to leave the Tenseiga with Bokusenō indicates that he thought that Bokusenō was the surest way to get the sword to Sesshōmaru without actually giving it to him directly, suggesting that Sesshōmaru visits Bokusenō with some frequency. Bokusenō reacts to Sesshōmaru's visits with mirth and is always willing to give him whatever information he requires. Despite the fact that Bokusenō maybe the closest thing Sesshōmaru has to a friend, it may not be that they actually consider each other friends, since Jaken refers to Bokusenō as "your father's friend" rather than "your friend." Nevertheless, Bokusenō seems to be the only demon besides Jaken & A-Un that Sesshōmaru gets along with, as he treats all of his other acquaintances, including his own mother, with disdain.
 * Bokusenō

Because of her affiliation with Inuyasha, and his former hatred for all humans in general, Kagome was generally disliked by Sesshōmaru, but he had a change of heart. While he grow to like her, eventually throughout the series he begins to look out for her; protecting her from enemies, such as Mukotsu and Naraku. Three years after Naraku's defeat, Kagome became his sister-in-law, though he finds the idea somewhat annoying, as seen by his glare when she shouts out "big brother!" to him on his way back from visiting Rin.
 * Kagome Higurashi

After having his left arm severed by Inuyasha as a result of his attempt to claim the Tessaiga for his own, Sesshōmaru sought a place to recover and passed through the Asano Castle (a two episode anime special). The Asano Clan happened to be on the brink of losing to an enemy, however, Sesshōmaru easily cut though the enemy lines with this claws on his way to find refuge. Princess Sara fell in love with Sesshōmaru at first sight when their eyes met as she saw him defeat her clan's enemies. As he rested, Sara hid behind trees and gazed at Sesshōmaru, often listening to his unconscious mutterings about wanting the Tessaiga. Later on, Sara became terminally ill and spent her final days in a convent with nuns after the Asano Castle was burnt down by her own father, who was driven insane after witnessing Sesshōmaru's strength. Like Onigumo, in Sara's final moments, she was visited by demons who explained to her that if she gave them her body, they would help her destroy Inuyasha, whom she had heard outside and recalled Sesshōmaru's previous words about wanting the Tessaiga. She gave into the demons and asked Sesshōmaru that if she were to fulfill his wish, that he would acknowledge her feelings for him. Sesshōmaru told her to do as she pleased. After presenting a stolen Tessaiga to Sesshōmaru, he rejected the stolen sword and revealed that he had no interest in such a thing. The demons then took over Sara's body and aimed to kill Sesshōmaru. Showing compassion, Sesshōmaru destroyed the demons within Sara, allowing her soul to be saved. He placed her flute in her ashes and told her to continue playing her flute in the netherworld.
 * Sara Asano

There is barely any interaction between Kikyō and Sesshōmaru, however in Affections Touching Across Time, they briefly encounter and Sesshōmaru asks her if she loathes Kagome or if she is "testing her". Kikyō responds that she despises all things and living creatures bound to time. Sesshōmaru tells her to do as she sees fit but states that he will be the one to kill Inuyasha. On Mount Hakurei, Kikyō shoots an arrow into the evil form of Suikotsu, saving both his good side and Rin. In the Manga it is even implied that Sesshōmaru is familiar with her scent, because when Kohaku wants to go and make sure that the Kikyō is alright, Sesshōmaru says that it's already too late.
 * Kikyō

There was barely any interaction between the Dog Demon Lord and the demon slayer, however in episode 20 (FA), Sango was the one to inform Sesshōmaru that Rin was unconscious because of Magatsuhi's poison making him hurry back to Rin's side. Then in episode 23 (FA) during the final battle with Naraku he becomes very angry with her after overhearing how she was willing to kill Rin in order to defeat Naraku and save Miroku in the process. She begs him to wait to kill her until after Naraku has been defeated. It seems that Sesshōmaru was indeed going to tear her apart after the fight, but decided to leave her in peace after seeing her give Rin her gas mask to protect her from the poison and apologizing to her.
 * Sango

It was Kōga's wolves that killed Rin, Sesshōmaru's traveling companion who he brought back to life. There was barely any interaction between Sesshōmaru and Kōga until episode 99, during which they almost fought when Kōga stated that he smelt like his brother, Inuyasha. This made Sesshōmaru mad and, if it hadn't been for the two demons that were about to attack their friends, they would have fought each other. However, upon defeating the two demons, they gained a mutual understanding (it has been stated that the one thing they have in common is that neither of them can stand Inuyasha).
 * Kōga

Manga vs. Anime

 * The energy whip of light is exclusive to the anime. In most of the scenes where Sesshōmaru uses the whip of light in the anime, in the manga he instead used his Mokomoko.
 * Sesshōmaru's first handful of appearances in the manga have a somewhat childish illustration, and he is shown smiling and mocking his enemies frequently. This part of his personality starts to fade little by little after he has his arm severed by Inuyasha. However, in the Anime he is cold and rarely shows emotion from his very first appearance.

Trivia

 * According to Rumiko Takahashi, Sesshōmaru's name means "killing perfection", though it can also be translated as "the perfect killer/assassin", "circle of destruction" or "complete destruction of life".
 * Sesshōmaru makes an appearance as a concept art in the front pages of Chapter 9, before he was introduced as a character.

 * Sesshōmaru's appearance changes as the story progresses. Comparing his first appearance in Chapter 13 with the last in Chapter 558, he appears very young and effeminate in the beginning, but by the end, appears more mature and masculine; the armor and clothes he wears changes slightly overall compared in Chapter 13, page 5 with chapter 468, page 1).
