Satsuki’s nephew, the son of Satsuki’s older brother, a junior high school student who enjoys dressing like a girl. His androgynous features allow him to pass off as a girl and his female persona is well-known as a cute internet idol. Aoi enjoys toying with the feelings of men, but is eventually exposed as a boy by Misaki. He later yells at Misaki for not being more decisive about her relationship with Usui, and for leading Shintani on, even if she was doing it unintentionally. It’s this scolding that eventually pushes her admit to Shintani (and probably for the first time, clearly, to herself) that she does in fact have feelings for Usui.
