Post a strange dream, Yuko Yoshida wakes up to find that she has grown demon horns and a tail. Consequently, her mother Seiko reveals that their family are the descendants of a Dark Clan who live in poverty because of the opposing Light Clan.

Yuko challenges Momo to a battle during the weekend, which ends up turning into an all-day running session; another demon girl prepares to set Yuko back on the right path.

Yuko's demon ancestor Lilith appears in her dream to give her some advice, only for her to forget everything she said when she wakes up.

Momo discovers a switch on the bottom of the statue that Yuko carries around. Upon being flipped, this switch gives Lilith the opportunity to possess Yuko's body.

Yuko buys a camera with the money she was going to use to pay off her debt.

Lilith sends Yuko into Momo's subconscious, where she ends up tidying the dark muck surrounding her dreams.
