Haise Sasaki has been living a normal life as a ghoul investigator at the CCG, living with his squad known as the Quinckes; Saiko, Mutsuki, Shirazu and Urie. What he doesn't know is that he used to be a ghoul himself with a group that resided in the coffee shop called Anteiku. In this group, he was close friends with a ghoul who goes by the nickname "Rabbit" to the CCG. Maybe an encounter with her at her new coffee shop ":re" will jog his memory back and this friendship will become something more.
