Kirishima Misaki

Takumi’s childhood friend who lives next-door and Rin’s elder sister. Contrary to her very adult-like appearance, she loves teasing people, especially Takumi. Furthermore, she loves making fun of him as well. She doesn’t seem to hold any romantic feelings towards Takumi, treating him more like a little brother. Though, later on, because of the license allowing them to have intercourse, her feelings (toward him) gradually start to change (for the better).
