中津川 初

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.
