Souta Tachibana

[Kaoru's](https://anilist.co/character/391311/Kaoru-Tachibana) younger brother. He used to work part-time at a restaurant, but Kaoru made him the dorm manager and supervisor. He's good at housework and has common sense, but has the annoying habit of instantly forgetting his sense of self and running around violently whenever someone calls him "Chibita." He's small.
