Chisami is Shougo's cute little, devilish angel younger sister, who Kiri indifferently "saves" one day when her hair was tangled in a bush. Because of this, Chisami seems to think that Kiri is her Prince Charming (as she thought Kiri was a boy). She later finds out that Kiri is a girl, but she still admires her and refers to her as Prince-sama. She and Iori always fight over Kiri, Iori as his "darling and friend", and Chisami as her "Prince Charming". In the end, she ends engaged to Iori, though they still argue often.
