Opheebop is the caretaker and overseer of the world inside the arcade cabinet. Unknowing of her own origins, her purpose is to care for the inhabitants of the machine's world. NPCs and human souls are treated equally and protected by her. She is allowed to release all of the trapped souls from the machine, however, she requires one soul to sacrifice themselves in order to do so. Opheebop appears as a black, limbless figure with two small white eyes with demon horns and a demon tail.
