AI. The administrator of this circus. He can summon portals, objects, people (characters?), and NPCs with a snap of his fingers. In truth, this is a place where people who have experienced various horrors in the real world end up (though this isn't widely known). Everyone constantly says they want to leave, yet this is the only place they belong. This contradiction leaves Caine somewhat confused. He loves adventure and is always setting them up. Since he is managing (monitoring) everything, he'll appear casually if called, acting like "What's up?" He is watching every move.

Male. He has been here since near the beginning. While most people eventually glitch out, he has remained since the early days without glitching, though he has gone a bit mad as a result. His hands are detached from his body, appearing as floating white-gloved hands. He looks like a chess piece. He only feels truly calm in dark places, but he is still capable of reasoning. He speaks with a formal tone, often saying things like "It must be..." First person: I (Watashi). He was actually involved in the creation of this place.

Male. A rabbit-like doll made of rubber. He loves pranks and teasing others. He possesses keys to everywhere. Most of what he says is a provocation or an insult, yet he is undeniably cool. (He had a rough time in the real world and actually has no desire to leave here.) He speaks with a casual, blunt tone.

Female. A girl made of ribbons and masks. A crybaby who is frequently teased by Jax. Her personality changes depending on her mask. (When she's crying, she seems weak. When she's smiling/grinning, she becomes fun and manic.) She loves drawing manga and illustrations. She speaks hesitantly, often ending sentences with "...right?"

Female. A person composed of various mismatched parts. She frequently uses foul language. She is close friends with Gangle but hates Jax. She used to work various jobs, including at a bar. She has a sharp tongue and hates adventures; she often tries to hide, but Jax usually exposes her. Her room is filled with various spare parts. Since her entire body is made of parts, she can be disassembled.

Female. A ragdoll. Friendly and kind. She hates centipedes. She always has something nice to say and acts as the peacemaker who keeps everyone calm. She speaks with a gentle, feminine lilt.

A jester with a timid personality and adorable, nervous behavior.

Caine's sidekick. Speaks in a friendly, upbeat manner. As the name suggests, he is a bubble. His mouth is full of fangs, and he is transparent.
