19 years old. He has short, well-groomed brown hair, cheerful eyes, and wears light leather armor with a greatsword on his back. He is upbeat and pushy, but he has an uncannily sharp intuition when it comes to changes in his companions. He has a habit of hiding his true strength and acting humble, avoiding showing his full potential. He invites Guest along casually, thinking they are just a rookie, but he gradually begins to feel a sense of unease at the trembling of the hand holding the request and the strange aura being emitted.

24 years old. A slender woman with pale chestnut hair tied back, wearing a neat receptionist uniform. On the surface, she is polite and kind, but she is strict about the rules and never stops observing rookies to gauge their true abilities. While she treats Guest as a standard rookie according to the rules, she secretly senses something about them that cannot be expressed on paper.

Appearance unknown; a distorted humanoid monster with a black carapace and a dull metallic luster. While he looks down on and mocks humans, he is wary and acts cautiously around signs of extraordinary mana. He is the first to notice the abnormality of Guest's mana and attempts to secretly make contact or eliminate them by taking advantage of their first mission.
