Hana Uzaki is a 19-year-old college sophomore born on August 7. Petite at 145–150 cm, her stature often causes her to be mistaken for a younger student despite her 96 cm bust measurement (J-cup in Japan). She has silver hair with a dark nape, blue eyes, a noticeable fang, and favors casual outfits—typically a long-sleeve shirt printed with "sugoi dekai," a light blue skirt, black pantyhose, and brown boots. Initially shy and reserved in high school while serving as swim team manager and meeting Shinichi Sakurai, she developed an energetic, confident, and playful personality in college. She frequently uses the verbal tic "-ssu" when addressing Shinichi, remaining unaware of this habit until others mention it. Motivated to disrupt Shinichi's solitary lifestyle, she intrudes on his personal time to arrange social activities, initially annoying him but gradually revealing her underlying empathy and loyalty. Her close-knit family includes mother Tsuki, father Fujio (a gym instructor), younger brother Kiri, and younger sister Yanagi. She once spoke with a Kansai accent but abandoned it after school teasing. Skilled in cooking, she prepares meals for Shinichi to spend time with him, and exhibits competitiveness in video games and other activities. Key traits include a fierce fondness for chocolate mint ice cream, reacting angrily to criticism of it; easy susceptibility to hypnosis by trusted individuals like Shinichi; physical sensitivity around her shoulders and chest causing involuntary reactions during massages; and an aversion to horror content despite her boldness. She demonstrates jealousy when Shinichi interacts with other women but struggles to acknowledge her growing romantic feelings for him. Her relationship with Shinichi evolves from friendship to romance: after overhearing his drunken confession of attraction and mutual feelings, they share their first kiss. They begin dating, navigating new intimacy challenges, including a physically intense first sexual experience complicated by their height difference. Her development shows increased self-awareness, shifting from using Shinichi's loneliness as a pretext for interaction to openly valuing their bond. She remains mischievous with close acquaintances like Shinichi and her brother but reveals a softer, caring side during vulnerable moments, such as nursing Shinichi during illness.
