Naoki Satou

[Shun](https://anilist.co/character/323205/Shun-Satou)'s senpai. She's cheerful, carefree and more than a little eccentric, being the president of her own "Hyper Go-Home Club", which she immediately recruits Shun for on their first day of high school. Despite her quirks and detour-loving personality she is kind, attentive and gets along well with everyone at school, quickly becoming close with Shun and capturing his interest.
