Students ; : :A very uptight girl with long blonde hair that is kept back with a hairband, Chitose is worried that the students of Shin-Inaka no Chugakko (Wapiko especially) will cause her newly-formed school to be worse than Tokai no Gakuen. She is very arrogant to the point where she is unable to escape from a burning building due to her belief that she was raised as a high-class girl, and that she is not as tough as all the country students of Shin-Inaka no Chugakko (who had all escaped from the building except Wapiko due to her trying to get Chitose to escape) as well as trying to frequently ban all normal customs of the school to enforce a more "proper" custom, such as a Tea Ceremony Club, but ultimately fails, due to her plans usually backfiring.

Sailor-fuku, the agile Wapiko may be viewed as the closest thing the series offers to a true heroine. Almost always depicted in a comical
chibi art style, she nearly always has a smile on her face and a happy-go-lucky personality, despite often being a chief instigator of events that bring anguish to Chitose. For being a middle school student, Wapiko tends to act and think like a small child. Nevertheless, her super speed,
bloodhound-like nose, winning spirit and bottomless appetite for fun have earned her the respect of the entire student body, minus Chitose.
