Yohakari Ayaka♀

Honor student and childhood friend of the protagonist. Despite being a year younger than him, she is very reliable. She comes from a family of five, including her two parents and two younger siblings, but their behavior is far from that of a typical family. As the eldest daughter, she dislikes being called 'Loli.'

Good at cooking and willing to take care of others, she is like an angel... that is until her interest in pornography comes to light. Her constant curiosity about obscene material often leads her to misunderstand casual, normal conversations, exposing her as a pervert—or a 'closet' pervert—since she consistently denies having such impure thoughts.

She is very happy to welcome the protagonist into her home, even calling him 'Onii-chan' as a way to persuade him to stay, despite her entire family wanting him out.
