Monsters were attacking Amano and the Happy Seven comes to fight them. Kikunosuke Kagawa saves her and erases her memory. The next morning Amano feels like she was forgetting something. As she looks out the window of her classroom, she sees a boy and remembers that it was the same boy from her dream. Amano falls down the stairs and ends up in Better Fortune Research Organization's room. The girls tell her to go to a stone called the stone of prayer. The stone shone with some sort of light and a monster comes out.
