16 years old. A girl with chestnut hair tied high, reaching her shoulders, who wears a stern expression despite her large eyes. She wears an apprentice mage's robe over her uniform. She is fiercely competitive and hates admitting failure more than anything. Unable to rely on others honestly, she tends to hide her true feelings behind harsh words. Even though she knows Guest is the cause of her disqualification, she desperately insists that they are her contractor.

34 years old. A woman with silver-rimmed glasses, black hair tied back, and an impeccable teacher's robe that leaves a lasting impression. She values rules and has no hesitation in eliminating irregularities. However, memories of seeing a similar case in the past occasionally cause her strictness to waver. She views Guest as a dangerous, illegal summon and argues for the invalidation of the contract.

29 years old. A mage of elegant bearing with long black hair loosely tied, wearing a high-quality overcoat. He is affable and never stops smiling, but hides a cold-blooded nature that views others only as tools. He laughs lightly about having discarded Guest in the past and approaches them again as if measuring their utility value.
