吉野 悠姫

Yuuki is a petit, energetic girl with odango and a first year student residing in Polar Star. She is the most hyperactive of the dormitory's residents, often acting childishly, teasing the other students, and reacting to situations with exaggerated mannerisms. She has a flat chest, and as a running gag, is often shown to be envious of more well-endowed students like Ryouko, though Ryouko and Megumi remain her closest friends in the dormitory. Yuuki is also frequently shown reacting in exasperation to Soma's antics.

Yuuki's specialty is cooking wild game. She raises and breeds a large number of game animals in the dormitory, including both deer and boar. During the Autumn Elections, she prepared a wild game curry that won high praises from the judges, finishing 7th overall in her block, but she was ultimately defeated and failed to advance to the main tournament.
