Kakurenbo

Children in fox masks gather among the ruins of a city to play a forbidden game of hide-and-seek. Those who take part are said to vanish, carried away by demons, but Hikora enters in hopes of finding his missing sister Sorincha.

Once the game begins, the abandoned streets offer few places of safety. As monstrous pursuers close in, the children discover that being caught means far more than losing a game.
