Kazuto Tanaki

Satoru is a fledgling writer. When his latest manuscript is rejected, his editor, recognizing his talent, offers him a cottage by the beach to work in peace. At first, he struggles, but he is driven to write after meeting a girl, Yoriko, on the beach.

One day, when three guys and one girl wake up in the morning, they're all in a small room filled with the white powder, naked. Why were they gathered? What does this room mean? Who brought them here? How to escape from it?
