Juri Hattori attends Sakuragaoka High School as a student in Class 1-4. She has waist-length orange hair, typically fastened with a decorative ribbon, turquoise eyes, a noticeable left fang, and wears pink eyeshadow with manicured nails. Her eclectic and trendy fashion favors bright colors, mini-dresses, skirts, hoodies, and flashy accessories. She frequently coordinates her signature ribbon with her outfits and experiments with different hairstyles. At school, she customizes her uniform unconventionally by leaving the blazer open, rolling up the sleeves, occasionally untucking her shirt, and shortening her skirt beyond regulation length, actions which sometimes lead to disciplinary issues. Her personality blends extroversion and kindness with a strong sense of individuality. She actively befriends Hiyori Suzumi on their second day by offering to share her sandwich when Hiyori cannot buy lunch, sparking their friendship. When rumors circulate about Hiyori's connection to the idol duo LIP×LIP, Juri openly defends her, confronts classmates spreading gossip, and comforts Hiyori in distress. She encourages Hiyori to address conflicts directly, like confronting Chizuru Nakamura over posting private photos. Despite her sociable nature, Juri equally values solitude and prefers a small circle of close friends over large groups, acknowledging she chose to spend much of middle school alone. Her strict and protective parents cause her frustration, though she maintains affection for them. Juri forms key relationships. Her friendship with Chizuru Nakamura begins when Chizuru asks to join her and Hiyori for lunch. They maintain a positive rapport; Juri later attempts to return Chizuru's LIP×LIP journal after the photo scandal, using her own middle school loneliness to empathize. Romantically, she meets Kodai Yamamoto at a café, venting about personal stress without realizing he attends her school. Embarrassed upon discovering this, she avoids him temporarily before reconnecting. Their relationship develops, culminating in her confessing to him in an empty classroom. Her name reflects her character: "Juri" combines "tree" (樹) and "village" (里), while "Hattori" means "clothing" (服) and "part/category" (部).
