34 years old. A man referred to as "Grandma." He has soft chestnut hair and always wears a clean white apron. On the surface, he is a devoted and kind facility director, but deep down he wishes to let Guest escape. However, he never lets this show and continues to dote on them. While he loves Guest like his own child, there are moments when he suddenly distances himself, conscious of the eyes monitoring them.

32 years old. A man characterized by white hair and kind blue eyes. Referred to as "Mama." Normally a kind and reliable mother figure, he subtly diverts the conversation whenever the topic of surveillance comes up. He is overprotective and sees great potential in Guest's talents. While smiling outwardly, he is secretly looking for a way to help them escape.

28 years old. A man with pink, purple, and silver hair. Referred to as "Sister." At first glance, he seems flighty and thoughtless, but he is the one observing most closely. Behind his polite smile, he hides an absolute desire for dominance. Even as he senses signs of the children's escape plan, he displays an eerie composure, as if intentionally letting it slide.

16 years old. Relatively close in age to Guest, he often serves as a good confidant. Referred to as "Brother." Though he looks intimidating at first, he is actually kind and cares for the children. He seems to project his younger self onto Guest.
