Riddle Rosehearts

Riddle Rosehearts is a second-year and the head of Heartslabyul. He strictly upholds strange rules made by the "Queen of Hearts." He's feared by the rest of the students because of his severe punishments towards those who break the rules.

Appearance
Riddle has red, mid-length hair that curves inward, V-shaped bangs covering his forehead, side bangs, and two strands of hair forming a heart on top of his head. He has a stern look and silver eyes.

He wears a small crown leaning on the left side of his head. His outfit consists of a white and red coat dress with the bottom being lined with a gold-coloured fabric. The inside of the coat dress is entirely red and has a pattern consisting of tiny hearts, spades, diamonds, clovers, and crowns. He also wears white trousers.

Personality
Riddle has a strong commitment and dedication for implementing the rules of the Queen of the Hearts and demands all residents of the Heartslabyul dormitory to obey all available rules. He has no problem "decapitating the heads of rule-breakers" (decapitating meaning using his unique magic to put that person in a collar). He is quite irritable and becomes very angry if someone admits that they are against the rules that he has set in place. After the events of Episode One, he becomes more lenient with his reinforcement of the rules but is still considerably strict.

Background
Riddle lives with his mom, the status of his father is unknown. He has implied that his parents don’t get along. Both parents are magic doctors, but his mother seems to be more well-known. To Riddle, she is extremely overbearing and planned out nearly every second of his life: controlled his education, his schedule, his diet, his clothing, the supplies he used, and which friends he could have. She put a heavy emphasis on studying and always being the best.

Unique Magic
Riddle's unique magic is called "Off with Your Head!" It causes a collar to lock around one's neck, sealing away their magic until he takes it off.

Trivia

 * Riddle's name is an allusion to Alice in Wonderland's protagonist, Alice Liddell, as "Liddell" and "riddle" are phonetically similar in Japanese. The last name Rosehearts comes from the words "rose" as a reference to the Queen's favorite flowers; and "hearts" as a more overt reference to the Queen of Hearts.
 * Riddle became a Dorm Leader a week after he started studying at the Night Raven College. That is to say, he was still a first-year when he became a Prefect.
 * Riddle doesn't have any siblings.
 * He's from a common yet famous family, because his parents are famous magicians.
 * It seems Riddle is very self-conscious about his height; he flares up immediately whenever anyone mentions his stature.
 * Riddle states furiously in the Ghost Marriage event story that he still has one more year to grow taller.
