The characters in HP came to a strange space one after another.
A gray ball told them that if they wanted to leave, they had to play a game. After the game, they would have nothing to do here.
There is a girl here who is unaware of their presence. She wears a blindfold and sleeps with her feet on the long table. The ball says her name is Cheryl.
In a daze, the game begins.

Cheryl had a dream, and she didn't open her eyes throughout the dream.
