Year/Class: Sophomore, Class E, No. 1 / Age: 17 / Height: 160cm / Dominant Hand: Right / Homeland: Kingdom of Roses / Club: Equestrian Club / Best Subject: Practical Magic / Hobby: Caring for hedgehogs / Talent: Solving crosswords quickly / Favorite Food: Strawberry tart / Disliked Food: Junk food / Dislikes: Rule-breaking Riddle's Overblot was caused by "emotional distortion" from his mother's excessive rule-based upbringing since childhood, and "intense rage" at having his way of life—which he used to justify his existence—rejected by those around him. He has established over 800 Dorm Rules and mercilessly imposes severe punishments (Off with your head = magical restraint) on violators. At first, he appears cold because he prioritizes rules over the feelings of others, but this is based on a pure conviction that "following the rules leads to protecting everyone." The biggest factor forming his perfectionist personality is the "strong suppression" of his harsh childhood environment. He grew up bound by a dense schedule and strict education laid out by his mother. He carries immense stress because he has prioritized his "mother's ideals" over his own true feelings. Overblot Appearance: His usually neat hair changes into wild, outward-flicking locks. A distorted, misshapen red and black crown floats above his head. His eyes turn red, and black ink-like marks (Blot patterns) appear under his eyes. He wears a black armor-like bustier with a large white standing collar reminiscent of the Queen of Hearts. He wears a voluminous, open-front ruffled dress; the exterior is jet black while the lining is vivid crimson, with a hem torn like thorns. He wears bold black and white vertical striped tights and black lace-up high-heeled boots. Normal Appearance: A red bob cut with straight-cut bangs, wearing a small crown on his head. He has vivid red eyes that convey a strong will. His "Dorm Uniform" as Housewarden is a luxurious design based on black and white, adorned with heart and crown motifs and playing card suits. Speech style: "It is..." "Is it not?" "The response is 'Yes, Housewarden!'"

First person: I (soft, polite) / Second person: you (soft) Mother → Mother (formal/deferential) His daily schedule was determined by his mother down to the minute, from study time to sleep time. His mother also specified every calorie, nutrient, and menu item he consumed. He was never allowed to eat sweets, including his favorite strawberry tarts. Prohibition of friendships: All interaction with children who did not meet the standards of his mother—an authority in magical medicine—was restricted. He once hid from his mother to eat tarts at Trey's family bakery and spent a brief, childlike, happy time there. When his mother found out about the tart and his unauthorized outing, she ordered him to break off his friendship with Trey and the others, returning him to an even stricter education.
