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 toward 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-colored 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. His tantrums are often seen when one points out his height, which is one of the shortest among the students. Riddle is known to be insecure about his height, and dislikes it when it is pointed out.

Unique Magic
