Summary

When poisonous yōkai breach her barrier and come after the hanyō children, Shiori enlists the aid of Miroku to put an end to them.

Plot
Setsuna tells Towa what had happened to her in the decade they were separated by time. In a flashback, Setsuna was guided by A-Un and Jaken to the hidden Half-Demon village. Setsuna walked through the forest and noticed a barrier and shortly meets Fūta & Raita. Shiori welcomed and let her stay until she'd become strong enough to return back to Kaede's village. She was helped by the adult half bat-demon Shiori, leader of the village of half-demons which she has kept safe with her incredibly strong demonic barrier. Setsuna was cared for by Shiori for 6 years before heading off to the village she was born. Setsuna's stay in the village didn't last long as she soon returned to the hidden village. When a poisonous moth-demon, by the name of Gaga Gozen, comes to devour the half-demon children, they are aided by Miroku as Shiori's demon-bat abilities have all been neutralized by the appearance of a solar eclipse and turning her fully mortal with black hair. This stirs the very powerful demon blood within Setsuna to emerge, further increasing Setsuna's dog-demon abilities to kill Gonzen in mere seconds. Miroku then knocks her out with poison from the demon-slayers, and applies a strong seal on her demon blood using the naginata she had taken from Gonzen as the focal point. With the battle over and her demonic powers back in full, Shiori re-erects the shield around the village, and has Setsuna live in the outside world with the promise that she should bring another half-demon, half-human child who feels troubled in any way; which was why Setsuna had brought Towa with her outside the cloaked entrance.

Trivia

 * It was Jaken who guided young Setsuna to the hidden village and gave her gifts to hone her combat skills per his master's request, though never revealed himself to her.
 * This marks the return of Shiori who made a single appearance in Episodes 73 and 74. Her human mother had died some years ago, having succumbed to illness.
 * Setsuna's battle against Gaga Gozen is very similar to Inuyasha's fight against Gatenmaru in episodes 51 and 52. Both Gaga Gozen and Gatenmaru are Moth yōkais who paralyze both Hanyōs, but are nevertheless destroyed by their mindless transformations.
 * This is the first episode where Moroha doesn't appear nor is she referenced at all.
 * This is the first time in Yashahime a half-demon transforms into a human during a solar eclipse as opposed to a new moon. In Inuyasha Jinenji becomes a human on a day in month.
