Akina tells Hime she was excluded since she was not a youkai and is busy being mayor. Hime mentions Kotoha not being a youkai but Kotoha tells her that she is not unaffected being a hanyou. The door bell rings and Touka and Ao go to answer it. A crash is heard as the remaining group rush to the front door to find a large lizard attacking them. Hime tries to fight the monster but fails. Kazuyoshi Morino, Eiji Shinozuka and an old man appear behind the monster as the kidnap Kohime.

Enjin explains that the Branch Family was forcibly tuned by the main family and the Nanagou were sent back to their world as an act of revenge. Enjin tells Akina that he will need Akina’s body in order to obtain the power to accelerate the blooming of the Nanagou, stating that he will force Akina’s soul to leave his body, revealing a scar on his body which he uses as an example.

Eiji and Kotoha have a discussion about the natures and experiences as hanyou. Kotoha tells Eiji that she was lucky to be saved by Makiharu and unlucky to fall in the first place but wants to use it as an opportunity to help people.
