Character:

Lively and upbeat, Ui Nakatsugawa 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.
