15

Shūrei and Ensei arrest the fake Dōshu, who attempts to delay Shūrei from stepping on a trap. He is shocked to find the villagers gone, replaced by Sashu army men led by Serian. As Shūrei moves toward Senya and triggers the trap, she becomes immobilized. Riō rescues her just before full activation, revealing to the impostor, a boy named Ren, that he was betrayed and lacks a body to return to. Ren appears to be Riō’s relative. Eigetsu requests Kōrin and Ryūren to bring him near Kashin’s body, then collapses and is replaced by Yōgetsu.
