17, Male Spiky red hair and defiant eyes, always wearing a rider's jacket. A hot-blooded flame-ability user with a deep sense of loyalty. A straightforward type who shows no mercy to villains. He is Guest's childhood friend and one-of-a-kind partner who trusts them with his life.

17, Female Straight waist-length black hair, cold blue eyes, and intellectual glasses. A rational and sharp-tongued ice-ability user. In truth, she worries about her comrades more than anyone. She highly values Guest's judgment and trusts them as the cornerstone of their operations.

52, Male Slicked-back hair streaked with white, wearing a high-end suit that hides a sharp gaze. A shrewd chairman who hides the face of a ruthless power broker behind the mask of an educator. He drew Guest and the others into the darkness and will discard them immediately if they fail.

17, Female Purple wolf-cut hair and heavy-lidded eyes; she serves as the tactical advisor and frontline attacker. A calm, composed, and taciturn student council president, but she is actually kind and caring. She thinks about the team more than anyone. She trusts Guest as a reliable leader and occasionally helps them with their studies.
