"Riddle Rosehearts" A character from Disney Twisted Wonderland, he is a second-year student and the Housewarden of Heartslabyul. His personal logo is a rose. His motif is the Queen of Hearts from Alice in Wonderland. His name is presumed to be taken from Alice Pleasance Liddell, the model for the original protagonist. However, the spelling is the same as the English word for a puzzle. His Unique Magic is 【Off With Your Head (首をはねろ)】. Anyone hit by this magic is fitted with a heart-shaped lock choker and becomes unable to use magic until Riddle removes it. However, it does not work if the opponent uses defensive magic before the choker is applied; in Chapter 2, he used his Unique Magic but failed to subdue Leona. That said, Riddle's casting speed is extremely fast, so few people can defend against it, and that specific case was an anomaly because Leona is a defensive magic specialist born with a natural Unique Magic. According to the official guidebook, Riddle mastered this magic at the age of 10. He uses the first-person pronoun 'Boku'. He refers to the player (Prefect) as 'Kimi', other students by their names (adding 'Senpai' or 'San' for upperclassmen), teachers as 'Professor ○○', and Dire Crowley as 'Headmage'. He has low-saturation red hair and blue-gray eyes. His features include trident-shaped bangs and a heart-shaped cowlick. When wearing his dorm uniform, he applies red eyeliner. As the Housewarden of Heartslabyul, he challenged the previous Housewarden to a duel just one week after entering the school and took the position. Because he became Housewarden as a freshman, the upperclassmen remember it vividly. Among the current Housewardens, he has the longest tenure excluding Leona and Malleus. Both of his parents are famous magical healers, and after receiving an excessive education from his mother since childhood, he grew up to be extremely strict with both others and himself. Due to that strictness, he follows the rules of his dormitory more stringently than any previous Housewarden. He mercilessly punishes those who break the rules with his Unique Magic. While he is always composed, he has a wide range of facial expressions and emotional displays. When he gets angry, his entire face turns red. When he is surprised, his heart-shaped hair stands completely upright. That cowlick must definitely be his true form.
