Episode 180

A Completed Meido is the 13th episode of InuYasha: The Final Act.

Plot
The demon Shishinki approaches Sesshomaru for a fight, having been defeated by Sesshomaru's father long ago. To Sesshomaru's surprise, Shishinki attacks him using a complete Meido Zangetsuha and claims Sesshomaru's father stole the technique from him. Sesshomaru attacks with his Meido, but Shishinki's absorbs it. Inuyasha and his group arrive and after Shishinki attacks him, Inuyasha joins the argument. Shishinki taunts Sesshomaru, telling him that he must have been shunned by his father if his half-human brother has Tessaiga as Tenseiga is just a cast off from it to contain the unneeded Meido. As Sesshomaru furiously wonders why his father did this, Shishinki attacks again. Inuyasha protects him with the Wind Scar, but Sesshomaru punches him and tells him not to interfere. Sesshomaru blindly charges Shishinki.

Miroku uses a paper charm to fire Myoga at Inuyasha so he can explain to Sesshomaru that his father entrusted him with the Meido because he felt Sesshomaru could master it, however Shishinki points out that he could have just given him Tessaiga instead of casting off Tenseiga. Sesshomaru resumes his attack. When Inuyasha again comes to his aid, their swords begin pulsating. When Sesshomaru draws Tenseiga, he is able to launch a massive complete Meido that swallows Shishinki. Inuyasha tries to tell Sesshomaru that Shishinki was lying, and that Tenseiga is a proper keepsake, but Sesshomaru states that they are destined to fight one another the rest of their lives. Myoga states Sesshomaru must have realized his father's true intentions.
