中津川初

和从都市的学校转校而来的一馬，第一个接触的少女。

活泼爱与人亲近，有着让任何人都喜欢的性格。

反过来说，过于纯真不懂得怀疑人，那毫无防备的行为也让周围的人（特别是伊吹）吃起醋来。

最爱自己出生成长的山比古町，希望这样的日子可以永远下去。
一馬的转入，让这样的初的心和环境产生小小的变化。

Ui Nakatsugawa is the main female protagonist of the series. Lively and upbeat, Ui is a second-year high school student who is arguably the most iconic character of the series. She is the first girl Kazuma meets and without a doubt, the first to kiss him. An energetic, carefree individual, Ui is fun, outgoing and adored by everyone, though she is comparatively naive to her peers. Of her most outward traits, Ui has an outrageous appetite for food.
