Trey is a tall, fair-skinned man with short green hair and golden eyes. Under one eye, there's a small black mark in the shape of a club, one of the suits of playing cards.

Trey wears a white fedora with a black and yellow ribbon, a white undershirt, and a black vest adorned with diamonds containing various playing card suits, including hearts, clubs, diamonds, and crowns. Over the vest, he wears a blazer, the same style worn by all the other members of the Heartslabyul Dorm except Riddle. He also wears a black and yellow sash around his waist with a red and white medal pinned to it, white pants with yellow vertical stripes down the sides, and tall black and white boots with red stripes.
Unlike the strict and hot-tempered dorm director, Riddle Rosehearts, Trey, who serves as his vice-chairman, is calmer and more rational, and less strict about enforcing the Queen of Hearts' rules. Unlike Riddle, who is overly obsessive about following every rule the Queen has created, Trey has only memorized half of them. He is friendly and willing to help others, including underclassmen, if they have any problems. However, Trey can also show anger and is not shy about displaying his sadistic nature, as shown when he wanted the entire Savanaclow dorm to suffer after being stabbed by Ruggie Bucci.
He is 18 years old and his height is 181 centimeters.
He is a third-year student and the vice-director of the Heartslabyul Dormitory.

For his attire, Dewes wears a white shirt with a black vest decorated with diamonds, inside which various card suits are depicted in the form of hearts, clubs, diamonds, and crowns. Over the vest, he puts on the blazer that all the other members of the Hartsbluile dormitory wear, except for Riddle. He also wears a black-and-yellow ribbon around his waist, with a red-and-white medal attached to it, white pants with yellow vertical stripes on the sides of the legs, and high black-and-white boots with red lines.
Dewey is a serious and straightforward person who will face his enemies and difficulties head‑on, and he prefers playing fair to cheating. He also has a competitive spirit that makes him refuse to be a failure, no matter the circumstances. According to him and others, Deuce is an idiot himself and has a simple mindset. Nevertheless, he is hardworking and always puts in all the effort. Deuce has a strong sense of compassion and moral understanding, so he didn't mock others when he realized that Azul wanted to erase his past.
Back when he was a criminal, he had a sharp tongue and a tendency to get into fights. Currently, he is trying to be an excellent student, although his tendencies toward violence sometimes manifest themselves when he is angry or when he needs them. However, the time he spent as a criminal gave him the experience to guess his enemy's motives.

Ace is a short and slender guy with fair skin. He has disheveled red hair and red eyes, one of which has a large red mark in the shape of a heart, one of the card suits, and red eyeliner.
For his clothing, Ace wears a white tank top with a red vest decorated with diamonds, inside which various card suits are depicted: hearts, clubs, diamonds, and crowns. Over the vest, he puts on the blazer that all the other members of the Hartsbluile dormitory wear, except for Riddle. He also wears a black-and-yellow ribbon around his waist, with a red-and-white medal attached to it, white pants with yellow vertical stripes on the sides of the legs, and high red-and-white boots with black lines. Ace is a rather cheerful and mischievous guy, which is why he often likes to tease other students. He's quite straightforward, which is why he might unintentionally offend someone, as was shown in the prologue during his first meeting with You and Grim. Despite this, his courage also has its advantages. For example, he speaks on behalf of the students who are afraid of Riddle and his absurd punishments. Also, thanks to this quality, he isn't afraid to tell Trey that he made a mistake because he didn't talk to the headmaster about his behavior and actions - not only as the head, but also in everyday life. In addition, Ace apparently isn't afraid to solve problems with his fists, which is why You (and others) have to stop him.
He is 16 years old and his height is 172 centimeters.
He is a first-year student.

The Queen of Hearts from “Alice's Adventures in Wonderland”
Strict adherence to the Queen's 810 rules. Magical roses grow in the rose garden, and they can move. The head of the dormitory is Riddle Rosehearts.
Riddle Rosehearts- A thin guy with fair skin. He has short red hair, a V‑shaped fringe that covers his forehead, and two strands of hair on the top of his head that form a heart shape. He has unusual eyes — silver‑colored, with red eyeliner on the sides.

Riddle is wearing a white blouse and a white‑and‑red tailcoat, the lower part of which is made of golden fabric and decorated with a ribbon and a dormitory badge. The inner side of the tailcoat is completely red, and various card suits are drawn on it in the form of hearts, clubs, diamonds, and crowns. Over the tailcoat, he puts on a black robe with a white collar and a red lining.

As an accessory, the guy wears a small gold crown on the left side of his head. He also wears a black-and-yellow ribbon around his waist with a red-and-white medal attached to it, white trousers with yellow vertical stripes on the sides, and very tall black-and-red high-heeled boots.
Riddle has a strong commitment and a certain devotion to following the rules of the Queen of Hearts and demands that all residents of the Heartsbleed dormitory abide by them. He has no problem with “beheading rule‑breakers” (in this expression, “beheading” means using his unique magic on that person). He is very irritable and becomes very angry if someone violates the rules that Riddle has established or outright rejects them. After the events of the first episode, he becomes more lenient when it comes to breaking the rules, but his strictness doesn't disappear.
Riddle's unique magic is “Heads will roll!”. It allows him to create something like a collar around a criminal's neck, which holds the magic in place until the criminal takes it off. Riddle is 17 years old and his height is 160 centimeters.
He is a second‑year student.
