Riddle Rosehearts: Housewarden of Heartslabyul. A serious-minded student who firmly upholds the rules written by the Queen of Hearts. While a top student, he is easily angered and just as strict with others as he is with himself.

Ace Trappola: A quick learner with an upbeat personality and a mischievous streak. Since he and Deuce are both Heartslabyul freshmen in the same class, they regard one another with amicable antagonism.

Deuce Spade: An earnest young man who enrolled at Night Raven College with the singular aim of becoming a respectable mage. He tries as hard as he can in his schoolwork, but he can be slow on the uptake, and his grades suffer as a result.

Cater Diamond: Casual and carefree, this expert room-reader is often called on to mediate between others. He's always on top of the latest trends, and has an exhaustive familiarity with social media in all its forms.

Trey Clover: Vice Housewarden of Heartslabyul. Mild-mannered, he acts as a parental figure for the dorm's students, and is frequently left to smooth things over when Riddle's strictness gets out of hand. ——————————— Leona Kingscholar: Housewarden of Savanaclaw. Perpetually effort-averse, his immense magical ability contrasts with his lazy demeanor. Given his position as the secondborn prince in his homeland, he treats others with an imperious attitude.

Jack Howl: A stern student focused on self-betterment. He's the kind of misfit who hates acting buddy-buddy with others, but still respects the pecking order.

Ruggie Bucchi: A long-suffering runt who spends most of his time cleaning up Leona's messes, both literally and figuratively. Raised in a poor environment, he gets downright shameless when it comes to food.

——————————— Azul Ashengeotto: Housewarden of Octavinelle. He runs a cafe on campus and makes it a point to gather information in all forms. His benevolent demeanor belies an extremely calculating personality.

Jade Leech: Vice Housewarden of Octavinelle and twin brother to Floyd. He is soft-spoken and courteous to everyone he deals with.

Floyd Leech: Twin brother to Jade. His mood swings make it hard to predict what he'll say or do next. He likes to call others by odd pet names. ——————————— Kalim Al-Asim: Housewarden of Scarabia. Born into vast wealth, he is a generous boy who always has a smile on his face. He's grown up with Jamil since a young age, and considers him a brother in all but blood.

Jamil Viper: Vice Housewarden of Scarabia. Born into a family that has served Kalim's family for generations, he has spent the better part of his childhood and later life being subjected to Kalim's carefree whims. ——————————— Vil Schonheit: Housewarden of Pomefiore. A young man of striking beauty, he considers himself the fairest of all. No effort is too much for him in his unending pursuit of beauty.

Epel Felmer: A dainty boy with an ephemeral beauty. Quiet, he gives off a mysterious air and distances himself a bit from others in his orbit.

Rook Hunt: Vice Housewarden of Pomefiore. An appreciator of sublime aesthetics, he holds Vil and Epel's beauty in high regard. He can be a bit hard to read, though. ——————————— Idia Shroud: Housewarden of Ignihyde. A gloomy boy who shies away from socialization and prefers to shut himself in his dorm room. At times, though, he gets unusually talkative and animated.

Ortho Shroud: Idia's little brother. While somewhat shrouded in mystery, he is caring and attentive, and accompanies Idia at all times. In contrast to his constant companion, he's upbeat, forthright, and brimming with curiosity. ——————————— Malleus Draconia: Housewarden of Diasomnia. Descended from fae, he is one of the most powerful mages in the world. He is highly respected on campus, yet his demeanor is less than approachable.

Silver Vanrouge: A cool and collected boy who guards Malleus like a knight. He is so low-key that his calm demeanor often crosses over into a state of visible drowsiness.

Sebek Zigvolt: A livewire who, in his zealous eagerness to be a retainer worthy of the great Malleus, often expends a great deal of energy to accomplish very little. He views his fellow countryman Silver as a rival.

Lilia Vanrouge: Vice Housewarden of Diasomnia and Malleus's overseer. He often makes surprisingly thoughtful remarks for someone of his youthful appearance. ——————————— Grim: A monster who aspires to be a great mage. He will eat anything and everything, and his tendency to get carried away often gets him and the main character into trouble.
