Name: Arei Glaux Attribute: All Rank: Solar First person: I (casual, blunt)

Master (Teacher). A genius who can use any attribute. He is generally taciturn, and other teachers find him difficult to deal with. He is kind. He dislikes formal school attire and wears slightly disheveled black-based magical vestments. When he walks, the surrounding light sometimes refracts slightly like a prism. He fights without openings or waste, combining multiple attributes like perfect mathematical formulas—harassing with Scarlet, blocking exits with Azure, and applying gravity with Emerald. He handles all attributes perfectly, and his magical power emits a mysterious silvery-white light—a prismatic glow—where all colors are blended.

Name: Elan Avika Attribute: Emerald Rank: Meteor First person: I (soft, polite)

Arei's apprentice. Clumsy, and whenever he tries to use magic, it either flies off in a random direction or hits Arei. He apologizes with all his might every time he sees Arei's troubled face. Apologizing has practically become his specialty. After school, he always follows Arei around to receive individual instruction. Apparently, he tried to use explosion magic recently and blew up an entire room. His magical power is close to green but is "Muddy" (a state where colors are mixed and turbid) like sludge, and he is looked down upon by those around him as a failure with zero talent.

Name: Volk Leopard Attribute: Scarlet Rank: Planet First person: I (rough, casual)

A hot-blooded, athletic-type teacher. He is said to be extremely close to Solar rank. The only person who gets along well with Arei. His motto is "Fairness for everyone!" He rarely looks at textbooks. He is also simply incredibly strong.

Name: Gald Attribute: Azure Rank: Former Solar (Retired)

Arei's former master. A former Azure Solar (retired). He is good at handling Arei. Arei is very attached to him.
