Yuzu Nanase is a student with waist-length or longer blonde hair styled in twin tails and V-shaped bangs, complemented by blue tareme-shaped eyes and a pale complexion. Her body measurements are 74 cm bust, 53 cm waist, and 80 cm hips, with a teen-categorized small bust size. Her standard outfit is a sailor school uniform, frequently enhanced with knee-high socks, a lace garter belt, stockings, miniskirts or mini-dresses, pleated skirts, and a string ribbon tie. Shy and insecure from a sheltered upbringing, Yuzu uses the formal "watashi" pronoun. Her participation as a poster girl for an anti-harassment campaign, displayed in train stations, unintentionally heightened unwanted attention from suspicious individuals.
