Kanako Yuzuki

She is friends with [Yoriko Kusumoto](https://anilist.co/character/17482) and sees Yoriko as her reincarnation.
~!She was then pushed by Yoriko at the train station and severely injured.
Later, she is revealed to be involved in an experiment where her head is put into a small box where she is somehow still alive for at least a few days after being taken away by [Amemiya](https://anilist.co/character/66437), who is in love with her.
[Youko](https://anilist.co/character/17239), who at first claimed to be her sister, is actually her mother. She is the result of the incestuous relationship between Youko and her father, Koushirou Mimasaka.!~
