Tenseiga

The Tenseiga (&#22825;&#29983;&#29273;) is a fantasy sword from the anime and manga series InuYasha.

The sword has a special property in that it cannot harm any living beings, which is ironic for a sword. However its power lies in the fact that it can bring the recently dead back to life as well as healing the wounded. The literal translation of the kanji is "heavenly life fang" or "fang born out of heaven", but these are not necessarily accurate representations of the name's actual meaning.

Tenseiga allows a powerful wielder to see and slay the beings from the underworld, as well as bringing up to 100 beings back to life in one swing.

History
The Tenseiga was created by the swordsmith Totosai from a fang of the daiyokai the Inu no Taishou the father of InuYasha and Sesshomaru. The Tenseiga has the power to cut beings of the next world such as pall-bearers who that take away the souls of the dead, this allows the Tenseiga to revive the dead. Tenseiga can revive 100 people with one swing, the opposite of the Tessaiga's ablitiy to slay 100 yokai with one swing. After the dog lord's death Sesshomaru was left the Tenseiga.

Originally Sesshomaru did not wish to have Tenseiga, because it could not be used as a weapon and he began to search for his father's other sword the Tessaiga. However the Tessaiga was left to his younger brother InuYasha and had a barrier which prevented him from using it, forcing him to look for another weapon. Sesshomaru hated humans and this prevented him from being able to use Tenseiga. It wasn't until he showed compassion and sorrow for the human girl Rin, that he was able to use Tenseiga. Upon using it's power did Sesshomaru start to value the Tenseiga.

Tenseiga has been used sparingly, mostly only when Sesshomaru feels like using its power for his own gains such as reviving the head of the y&#333;kai Goshinki so that his fangs could be used to create the sword Tokijin; or when the sword compels Sesshomaru to use it for a good cause. Sesshomaru does not fully understand the behavior of the sword but he keeps it by his side for it almost always has some unforseen benefit.

Sesshomaru's human companion, a human girl named Rin, is brought back to life with the Tenseiga after she was killed by the demon wolves of K&#333;ga; Jaken, Sesshomaru's assistant, is also revived by Tenseiga as well after Kaijinbo kills him while under the corruption of the Tokijin.

Tenseiga, interestingly, easily defeats the leader of the elite cats of the west, Oyakata, who becomes an undead when he is revived with the souls of his lieutenants who laboured to complete the task and 3 pieces of the Shikon Jewel. Using the sword, Sesshomaru restored the life back to the lesser cats, thus taking Oyakata's life essence away. InuYasha is then able to finish the job with the Tessaiga and put an end to the renewed war between the Cats and the Dogs.

Since Tenseiga can harm the beings of the netherworld, the guardians at the gate that separates the Living World and the Dead, Gozu and Mezu, will not attack anyone who wields the Tenseiga, thus allowing them to pass the gate unobstructed. However, Tenseiga is not all-powerful as apparently it is not able to save Kagura, the wind sorceress created from Naraku and wind. The sword is either unable or unwilling to help such beings that do not possess a soul to begin with.

In the third theatrical release of the InuYasha series, it is shown that when InuYasha and Sesshomaru's father was still alive, he saved InuYasha's mother Izayoi and baby InuYasha with the Tenseiga. Subsequently, as the events developed, Tenseiga and Tessaiga, and in turn Sesshomaru and InuYasha, combine their power to utterly destroy S&#333;'unga, the sword of world conquest, which is more powerful than either of the other two swords alone and has a mind of its own that is bent on destruction.

Reforged Into A Weapon
It is later reforged by Totosai, after Tokijin is broken, and it gains the Meidou Zangetsuha, which allows it to send enemies directly to the land of the dead as well as its previous revival power. Thus, Sesshomaru finally accepts its potential as a weapon. When the Meidou Zangetsuha was used for the first time it was shaped like a cresent moon. Totosai explains that as Sesshomaru gains strength the Meidou will become more like a full circle, that will send the entire body of a enemy into hell. Sesshomaru goes on a quest to complete his new technique.

As Sesshomaru trained with the Meidou Zangetsuha the cresent moon shape got bigger, but it did not take the shape of a circle, to solve this problem Sesshomaru visited his mother to ask if his father told her anything about strengthening the Tenseiga. This led Sesshomaru to going to hell to rescue Rin from a dead soul. He found Rin dead and tried to use Tenseiga to revive her only find out that the Tenseiga can only revive a person once. Sesshomaru's grief over losing Rin and realizing she only died because she traveled with him strengthed the Tenseiga and Sesshomaru used it to purify the souls of hell and create a path to the living world. The Meidou became closer to a oval shape and grew larger. Sesshomaru's mother reveals that he must have a compassionate heart, which was what allowed the Tenseiga to grow stronger. Sesshomaru's mother used her Meidou Seki to revive Rin to make her son happy.

Continuing his quest Sesshomaru runs into Shishinki an old enemy of his father's and discovers that Tenseiga was casted off Tessaiga to contain the Meidou Zangetsuha technique. During Sesshomaru's battle with Shishinki InuYasha comes to his aid and in the presence of Tessaiga the Tenseiga resonanates. Sesshomaru uses the Meidou Zangetsuha and it becomes a full circle this time, and sends Shishinki's entire body into hell. Sesshomaru confronts Totosai about the Tenseiga (going as far as to fire a full Meidou at him), and he discovers that his father intended for him to master the Meidou Zangetsuha and then allow Tessaiga to reabsorb Tenseiga to gain the completed technique.

Sesshomaru, in anger of his father supposed betrayal teams up with Naraku yet again to battle InuYasha. He puts a fragment of Kanna's mirror on the Tenseiga which allows the sword to steal all of Tessaiga's ablities. Sessohmaru uses the newly empowered Tenseiga to battle InuYasha and the powerless Tessaiga to see if he is fit to be their father's successor. When InuYasha defeats the Meidou Zangetsuha and the stolen powers of his own sword Sesshomaru breakes Tenseiga on Tessaiga which not only restores it's powers, but grants Tessaiga the Meidou Zangetsuha just as their father intended.

When Tenseiga was later revealed to still be intact with it's original powers, Sesshomaru decided to keep the sword. Later Totosai reveals that the Inu no Taishou set all of this up to force Sesshomaru to lose his desire for Tessaiga and grant him his very own sword created from his own power, the Bakusaiga.

Teaching Compassion
It has been suspected that the Inu no Taishou left the Tenseiga to Sesshomaru for a reason, but the reason was never fully explained until near the end of the series. According to Totsai, Sesshomaru was given Tenseiga was because it could protect him from Tessaiga while it could not be used to harm InuYasha, in order to teach them to get along. Sesshomaru hated humans and cared very little about others and the Inu no Taishou knew of this and hoped to teach him compassion by giving him Tenseiga. Since Tenseiga could not be used by someone without compassion he hoped that Sesshomaru would learn compassion in order to use the sword.

This is reinforced when the Meidou Zangetsuha is unlocked by Sesshomaru feelings of anger and sorrow at Kagura's death. To strengthen the Meidou his father set up the training method that would teach Sesshomaru the meaning of losing someone close to him and have compassionate heart.

Special Ablities

 * Healing Cut: is the special ablitiy that can restore the life of the dead by cutting the pale-bearers who take the souls of the dead. The Tenseiga can also cut beings from the afterlife or the undead.


 * Meidou Zangetsuha(removed) : is the special ablitiy that can create a path into hell. The technique creates a massive black circle that will send a opponents entire body into hell. Tenseiga lost this technique when Sesshomaru broke the sword over Tessaiga so it could absorb the Meidou Zangetsuha.
