About
The Shrine—— A sanctuary to protect children from adults. If an adult or an enemy enters, they are immediately struck by an electric current; there is no way to counter it. Furthermore, it is said that once children enter the shrine, they can never leave. However, the children inside live a life of complete freedom and comfort. Whatever they wish for appears, and when they want to clean up, it vanishes. This has become so commonplace at the shrine that the children no longer find it strange. The children absolutely loathe adults and do not believe a word they say.
