Tennouji, Nagisa

天王寺渚 (ナギ

A second-year high school student. Nagi has brown hair styled in twin pigtails. She is nearsighted and wears glasses. She typically serves as the tsukkomi (straight man) to the boke (fool) antics of the other three, and she is sensitive regarding her weight and body shape.
Nagi is particularly vulnerable to cold weather; she would cover her entire body except for her eyes, even when snow was merely forecasted. She makes resolutions to diet and lose weight, but she dislikes exercising and has not succeeded.
