Yomi Kasuga, a demon tamer sent by the Urakai, arrives in town to stay at the Yukimura residence. Tokine is shocked to find out that Yomi was a former acquaintance of her father Tokio Yukimura, which forces her to recall of his death. Yoshimori and Tokine suspiciously find Yomi at the school grounds at night. On the following night, it is seen that Yomi summoned her ogre demon named Yoki after sedating Yoshimori, while she sends Tokine in a pitfall. Even though Tokine soon manages to escape, she is soon faced against Yomi. Tokine sets up a barrier around her, yet Yoki gradually tries to crush her from the outside.
