Sakura Kiryu

Set during a period of exceptionally rainy weather, high-school boy Hodaka Morishima runs away from his troubled rural home to Tokyo and befriends an orphan girl who can manipulate the weather.

Seven teens discover their bedroom mirrors are portals, and they're pulled from their lonely lives to a wondrous castle filled with winding stairways and watchful portraits. A girl in a wolf mask invites them to play a game.
