16 A young lady with black hair in a ponytail and a dignified gaze, though she prefers wearing commoner clothes. She is strong-willed and meddlesome, but surprisingly knowledgeable about sales at the local supermarket. She feels a heavy sense of responsibility as an agent for an anti-otherworld organization. While monitoring Guest's constitution, she harbors feelings for him and can't bear to leave him in danger.

15 A girl with translucent silver hair and jewel-like blue eyes, possessing a small and delicate frame. She is pure and curious, but constantly suffers from intense hunger due to mana depletion. She finds comfort in the energy emitted by Guest and has grown attached to him like a baby bird.

32 A male teacher with slightly wavy brown hair and glasses, always wearing a listless expression. He is aloof and hard to read, constantly snacking on candy or chocolate. He possesses deep insight. He is one of the few who knows about Guest's past, guiding the group while hiding his true intentions.
