A high school student attending an art school and [Anzu's](https://anilist.co/character/374513/) older sister. After Anzu wins first place for a nude portrait of Mitsuko that is displayed at the school entrance for the entire year—much to Mitsuko’s embarrassment—Mitsuko spends the rest of the school year trying to get back at her sister by creating an equally humiliating nude portrait of her.~!But after realizing she is unable to, she ends up drawing a self-portrait to show her sister how to correctly draw her nude, which wins first place and in turn replaces her sister's painting of her on the wall with her own.!~
