Riddle Rosehearts

Riddle Rosehearts is a second-year and the dorm 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 Rosehearts is a hard-working individual and one who is fully determined to be at the top of his field, competent inside and outside of his school activities. He is known to help his peers in need, whether it be underclassmen, upperclassmen, or fellow students from the same grade. As studies are his forte, he will aid those who struggle academically, as seen with his interactions with fellow student and dorm leader Kalim and his underclassman, Deuce. He is also capable of seeing potential in a person, as he views Epel as someone who can grow and reach to the fullest of his abilities and thus supports him in his growth. Riddle is also intelligent and more than capable in the fields and studies he pursued, often being the top of his peers and maintaining such position. As such, he is able to master studies that are supposedly above his grades, as he helped Cater, an upperclassman, in his studies.

Riddle sees the Queen of Hearts as a role model and holds dear the principles she has cemented, finding her elements befitting for all to follow as an example. Just like the Queen of Hearts, Riddle is a very strict and stern leader figure, demanding those around him, whether inside or outside of the dorm he orders to bid by the rules, and will not hesitate to punish those he saw has broken said rules. Like the Queen herself, Riddle has a short temper and has a knack of throwing tantrums.

Background
Riddle is a single child and lives with his mom. The status of his father is unknown, however, he has implied that his parents don’t get along. Both parents are magic doctors, but his mother seems to be more well-known. Because they were magic doctors, his parents raised him to become a magic doctor as well.

Riddle's mom planned out nearly every second of his life, as she controlled his education, his schedule, his diet, his clothing, the supplies he used, and the friends he could have. She placed a heavy emphasis on studying and always being the best, and due to this, she forbade any form of recreation in the house. As a result, Riddle took to solving crossword puzzles at the back of the textbooks that he was given to read as a form of entertainment, training himself to solve crossword puzzles very quickly to challenge himself. He even made his own crossword puzzles to give to Trey and Che'nya to solve, and throughout the years, he has made over 3000 of them.

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.
