Yūki Yoshino is a 92nd Tōtsuki Generation student and a resident of Polar Star Dormitory. Yūki is a petite young girl with teal colored eyes and amber-colored hair tied neatly into two buns on the sides of her head. When she lets her hair down, her hair reaches the bottom of her head, except for her bangs which barely reach her eyes. After four months, her hair has grown longer. Yuki wears a standard Tōtsuki uniform depending on the season. When cooking, she wears a standard white chef's uniform with black trimmings. During the 43rd Annual Tōtsuki Autumn Election Semifinals, Yūki wore a happi coat over her summer uniform when she was cheering for Megumi. Yūki is a spunky, cheerful, and cheeky girl with a "bright" and "contagious" smile. She can be childish as she enjoys teasing others. Although she acts quite innocent for the most part, she is just as competitive as everyone else and will readily show off her skills if challenged. She loves to gossip and immediately shows interest whenever she sees any sort of romantic hints from anyone. Yūki has the habit of adding "-cchi" to the names of people she likes (i.e. Nikumi-cchi, Erina-cchi). Yuki is very passionate and feels emotions strongly. She is also able to swing between moods, from being worried to being angry or sad. She is very loyal and supportive of her friends and her main aspiration is to keep the entire 92nd Generation residents of Polar Star together through their Tōtsuki life. To illustrate the extent for her desire to keep everyone together, after Sōma returned after having a Shokugeki against a Tōtsuki Alumnus to keep Megumi in Tōtsuki, she immediately slapped him in the face for doing something reckless that could have gotten him expelled. She is somewhat self-conscious of her body and gets upset at more well-developed female characters.
