Kanako Yuzuki

Yoriko later pushes Kanako at a train station, severely injuring her. Kanako is revealed to be part of an experiment in which her head is placed in a small box, where she remains alive for at least a few days after being taken by Amemiya. Youko, initially presented as Kanako's sister, is actually her mother, and Kanako is the result of an incestuous relationship between Youko and Koushirou Mimasaka.
