Summary
Thanks to his adventure in the Underworld, Sesshomaru has strengthened the Meido Zangetsuha, making turn from a cresent moon shape to the shape of an eye/oval.

The end result of their meeting leads to a fight! Wait a minute... is this newcomer using the Meido Zangetusha!?

Plot
Sesshomaru's group is traveling with Jaken sighing; he knows the Meido isn't a complete circle. This has made Sesshomaru's worse qualities come to the surface much more. An eyeless girl, approuches them, asking if Sesshomaru would wishes to know what Tenseiga is missing. Jaken yells at the girl, but is silence by Sesshoamru; as always, Jaken claims to not have said anything as Rin asks why he lies. The eyeless girl has Sesshomaru follow her.

Elsewhere in a ravine, Inuyasha's group follows after Kohaku's shard; Inuyasha can smell Seshsomaru as well. Though this makes it harder for Naraku to complete the Shikon no Tama, Sango is worried.

Ahead, Sesshomaru's group is lead by the girl, with Jaken asking if his master knows her; this is not the case. Jaken then wonders if Sesshomaru has suspected this a trap; promising a secret about Tenseiga is a bait too juicy to resist. Sesshomaru says he'll slay the girl if that's the case. However, the girl has vanished. A sphere of purple energy comes at them, barely missing; Kohaku and Rin board A-Un while Jaken falls. Sesshomaru flies up to see the sender of the attack and the girl. Sesshomaru tries to destory their footing with a Meido while Kohaku rescues Jaken. The sender of the energy attack notices Sesshomaru deliberately aimed below them so he can learn about Tenseiga. Sesshomaru demands the stranger reveal what he knows, learning he fought Tenseiga when the blade was weilded by Inu no Taisho; however, Tensiega "looked different" back then. Jaken yells in anger for the demon appearing so young when he's much older. Sesshomaru swipes at the demon, but misses, only killing his assistant. The demon tells Sesshomaru it's a deadly mistake to not use Tenseiga, launching another blast, which barely miss A-Un. Hitting a cliff, the blast turns into a Meido!

This confuses everyone, who note its size is small, but in the shape of a complete circle. The demon reveals that the technique was stolen from him along with the upper left side of his face, which he hides with a mask; despite missing half his brain, he's still alive. Sessomomaru quickly gueses this is just a plot for revenge against the son of Inu no Taisho as he is no longer around. The demon says only one user is needed for a technique, and that Tenseiga is an incomplete blade. This shocks Sesshomaru, who barely is missed by another Meido. As the demon refuses to reveal the truth, Sesshomaru attempts to send him to Hell with his own Meido. However, it is merely sucked into a smaller one as Sesshomaru is taunted by how malformed and needlessly large the Meidos created by Tenseiga are.

Inuyasha's group arrives, something that annoys Sesshomaru. The demon notices Tessaiga at Inuyasha's side. Myoga yells the demon's name "Shishinki", explaining that Shishinki is known as the "Ogre of Death", and should be dead. Myoga is now worried that Tenseiga's secret will be revealed. Recognising Myoga, Shishinki sends a blast at Inuyasha's group, which everyone manages to evade. Pissed off, Inuyasha jumps in to attack Shishinki with the Wind Scar. Shishinki evades it, revealing he knows Tessaiga well and that he knows that Inu no Taisho had two sons. Inuyasha demands answers from Sesshomaru, who is told by Shishiki that Tessaiga should have been HIS inheritence. This brings back bad memories for Sessomaru. Shishinki wonders why Inuyasha has Tessaiga, making Jaken yell in anger about all the time Sesshomaru has failed to take Tessaiga; he even losing his left arm as a result. Kohaku tells Jaken that the explaination makes sense, but Rin says if Sesshomaru heard him, he'd have been punished for revealing one of Sesshomaru's losses.

Sesshomaru demands to know why Shishinki is wasting fighting time on chatter. Inuyasha's group is surprised as they watch both Meido's clash and vanish. Myoga has now abandoned Inuyasha for the safer location his friends are at. Shishinki explains that he faced Tessaiga, not Tenseiga; in fact Tenseiga didn't even exist back then. Shishinki guesses Inu no Taisho couldn't control Meido Zangetsuha after stealing it from him, leading to it being discarded in Tenseiga, a sword born of Tessaiga. This angers Sesshomaru, who Shishinki believes was ignored by Inu no Taisho, who left Tessaiga to Inuyasha. Seshomaru thinks of what Tessaiga has done: rejecting him with a barrier, cutting off his left arm. Tenseiga had been useless until Kagura's death allowed him to master Meido Zangetsuha, which is now revealed to be a cast-off techinque. Sesshomaru furiously wonders why his father did this to him. Shishinki explains that Tenseiga is an incomplete sword, so the Meidos it launches are incomplete themselves as a result; no amount of training can change that. Shishiki tries sending Sesshomaru to Hell, but Inuyasha uses the Wind Scar to divert the Meido.

Shishinki tells Inuyasha not to be impatient by helping Sesshomaru; they'll fight once Sesshomaru is dead. Sesshomaru punches Inuyasha, telling him not to interfere. Kagome, Miroku and Sango quickly realises Sesshomaru is at the boiling point after hearing the truth about Tenseiga; however, Kagome wonders why the Meido Zangetsuha was left in Tenseiga instead of being destroyed. Knowing how angry Sesshomaru will be once the full truth is revealed, Myoga keeps quiet. Sesshomaru attempts to kill Shishinki, but is forced back by a barrage of Meido's. Everyone tries warning him against it, but Sesshomaru's judgement is too clouded by rage to think clearly. Myoga says he must tell Sesshomaru the truth about what Inu no Taisho had planned, but laments being unable to reach him. Miroku sends Myoga to Sesshomaru via a thrown sutra. Myoga explains since unlike a half-demon like Inuyasha who would be overwhelmed by the Underworld's demonic energy, a full-demon like Sesshomaru was entrusted with mastering the Meido Zangetushay. Shishinki then wonders why Tessaiga was not simply bequeathed to Sesshomaru instead. Myoga says it's a good point and flees.

Sesshomaru charges at Shishinki, who sends his left sleeve to the Hell; however, Sessomaru break Shishinki's mask with his claws as being reminded of losing his left arm angers him. Shishinki is angred by this, but Sesshomaru says a filthy mouth like Shishinki's defiles Tenseiga. Inuyasha tries using the Adamant Barraga, but the the Meidos simply absorb the spears of adamant. Tessaiga and Tenseiga begin simotaneously pulse, which Sesshomaru realises it Tenseiga telling him to help Inuyasha and Tessaiga. Shishinki fires a barrage of Meidos, which cannot be dodged. Though he may never be able to understand his father's reasons, Sesshomaru is now angry Shishinki thinks he can take his life. Sesshomaru fires a Meido, but it grows to gigantic porportions and swallows Shishini's Meidos. As Shishinki is pulled in, he realises Tessaiga helped Tenseiga complete the Meido, realsing Inu no Taisho's real plan. Being sucked into the darkness of the Underworld, Shishinki yells that he pities Sesshomaru for what his father had planned was truly cruel.

Once the Meido closes, everyone is left amazed. Not too surprising, Myoga ended up on Kagome's shoulder, a safe distance from the fight. Sesshomaru stares at Tenseiga, but remains unresponsive to Inuyasha's questions about Tenseiga. Inuyasha says that Shishinki was lying, Tenseiga is a complete blade with a complete Meido Zangetsuha; Inuyasha is only trying to get Sesshomaru to stop bugging him about Tessaiga, wanting him to accept Tenseiga as a proper inherence from their father..Sesshomaru is annoyed by Inuyasha's lack of understanding; it was because both blades were together that the Meido could become a complete circle. They are destined to fight to the day they die. Sesshomaru leaves with Kohaku, Rin and Jaken following on A-Un. Sango is left concerned.

Myoga goes on to explain that Tenseiga was entrusted to Sesshomaru because he was trustworthy of mastering the Meido Zangetsuha; however Myoga is now left worried as Sesshomaru knows the true hidden purpose of Tenseiga.

Trivia
