Remi Izumi features exclusively within the narrative of "School of Masochists" (or "School of Bondage"). She holds the position of music teacher at the school. Disillusioned by his parents' failing marriage and adopting a delinquent lifestyle where he views women as sexual objects, the protagonist Keisuke Shimizu targets Remi Izumi as one of his early victims. Keisuke trains Remi to become his sex slave. This establishes a recurring pattern where Keisuke exploits women, with Remi serving as his initial victim before he shifts focus to Orie Yuki, a class representative.
