Episode 22 (Hanyō no Yashahime)

"The Stolen Seal" is the twenty-second episode of Hanyō no Yashahime.

Synopsis
Lady Zero disguises herself and approaches Miroku, whom she traps and undoes the sacred seal he himself had placed on Setsuna to render her demonic blood dormant. This predicament causes Setsuna to turn full demon with red eyes and butterfly wings and to go utterly berserk. She recognizes Lady Zero as the one who had entered her mind while she was dreaming a decade ago. How will Towa and Moroha stop Setsuna from destroying them and everything else?

Plot
Zero steals from Miroku the seal he used to contain Setsuna's demon blood and dispels it, making Setsuna losing control of her powers and begin a rampage. Towa and Moroha attempt to stop her to no avail until Miroku's eldest twin daughter Kin'u learns the situation from him and both she and Hisui come to their help.

By their instructions, Towa risks her life to restrain Setsuna long enough for Kin'u to restore the seal and have Setsuna recover her senses. However, the seal did not contain Setsuna's demonic blood completely and she swears to take revenge on Zero for what she did. Zero came to the ruin of Izayoi's mansion where the Great Dog Demon fought Takemaru. Meanwhile at the modern era, Towa's teacher notices the Dark Comet approaching again before having an encounter with Sōta and his daughter Mei.

Trivia

 * Kirinmaru has a scar from his confrontation with Towa.
 * Tōga's statement to Zero about her being who she is acts as a callback to what Towa said to Riku in the previous episode.
 * Rin is revealed to be linked to Zero, which could explain Sesshōmaru's inaction when Zero had the forest his daughters were in burned.
 * Setsuna sprouting butterfly wings seems to be a side-effect of the Yume no Kochō curse.
 * Grim Comet has appeared in both the Sengoku jidai and Modern era. This opens the possibility of two part attack on in between eras; Inuyasha and Kagome will definitely be released from the Black Pearl for one attack, but which era is up to debate.
 * This is the first time that Tōga makes an appearance other than of the third movie.

Error

 * Tōga cast a complete Meidō Zangetsuha with Tessaiga despite the fact that Tenseiga was created to contain it and was entrusted to Sesshōmaru to perfect it.
