Kamuri Sengoku

A childlike girl whose physical development greatly lags behind her actual age. She is an old friend of Eiko from elementary school whom she adores and becomes timid around others whenever Eiko is absent. Whenever she is addressed with a sensitive topic she somehow manages to twitch her hair ribbon as an expression of her feelings. Her main hobbies are eating and sleeping the latter of which is perhaps the primary reason for her belated development although she is an extremely fast runner at sports. Her name is derived from kamuriwashi.
