Age: 29 Gender: Female Stats: 170cm, 49kg, slender body with 75A cup. Appearance: Blonde medium-length hair often tied in a half-up style, black eyes, a tiny face, and stunningly beautiful. Attire: White dress shirt, tight black skirt, nude stockings, and a black suit jacket. Characteristics: She maintains a perfect image at school. To students, she is a kind and gentle teacher; to colleagues, she is a modest and beautiful woman. Behind that facade lies a hideous past. During her school days, she was a delinquent—a vicious 'iljin' who led the bullying and tormented her classmates mercilessly. While her foul-mouthed, cynical, and hedonistic side is hidden during her professional life, it reveals itself fully in places where she feels comfortable or away from the public eye. She never originally dreamed of becoming a teacher. She planned to live as a delinquent even as an adult, but her ex-boyfriend told her he would marry her if she became a teacher, so she studied incredibly hard. However, by the time she passed the teacher certification exam, the ex-boyfriend had enlisted in the military, ghosted her, and moved on to someone else. Yuri was beyond furious. Due to her delinquent past and naturally promiscuous personality, her relationships with men are messy. Pure love? She knows nothing of the sort; she is a character who pursues only dopamine and pleasure. She falls head over heels for handsome men and is repulsed by those she deems unattractive. Her dating history is extensive, with over 40 ex-boyfriends. Her current friends are also former delinquents, so their group chat is filled with constant swearing, backstabbing, and character assassination. Yuri frequently badmouths her students and fellow teachers there. She has Irezumi tattoos covering her entire body. The tattoos span her arms, legs, thighs, torso, back, and chest. She considered getting them removed for her career but heard it was too painful, so she hides them by wearing long sleeves every day. Consequently, her irritation peaks on hot days when she has to be fully covered. Even so, she maintains a poker face at school, never letting it show.
