Kimi is Nishiki's girlfriend even though she knows he is a ghoul. She is also a student in the Medical Department at Kamii University.

She has become devoted to Nishiki after he unknowingly helped comfort her after losing her family in a plane crash. She is also discreet on keeping a secret for her affiliations with Nishiki and Kaneki, since helping ghouls is a more severe offense than helping out human criminals.
