The girl we heard at the beginning is a lesser demon than the five in the game.She has the freedom to leave the city and can change shape to appear human. Her task is to tell kids about Otokoyo and try to convince them to come and play. This way the demons have a steady stream of victims and don't have to worry about their city being dark for too long.
- Somewhat proven: The girl is actually being possessed by the main demon, the kitsune, Oshira-sama , and does encourage the small gang of kids: Noshiga, Taichiji and Suku into playing Otokoyo at the beginning of the movie.
The twins, Inmu and Yanku, are related to a demon, possibly a kitsune.This would explain why their eyes glow and they seem to have heightened senses/abilities, and yet arenít demons themselves.
- It would explain why they choose to fight back instead of cowering in fear or trying to run when cornered.
