18-year-old Ryohei Arisu is tired of his life. School is unbearable, his love life is a joke, and his future weighs down on him like an impending disaster. As he tries to survive in a world that doesn't care about him, Ryohei feels that everything would be better if he were anywhere else. When a strange fireworks event transports him, along with his friends, to a parallel world, Ryohei thinks that all his wishes have come true. But this new world is not an empty paradise, it is a ruthless game. And the only way to survive is to play.

Agunin now controls The Beach, and one of his first actions as king is to lock Ryohei in a room on one of the empty floors of the hotel, so he dies from an expired visa. But Ryohei receives unexpected leniency when The Beach becomes the arena for a fierce game of Hearts! Can he survive a hunting process and extend his visa, or has he just exchanged one terrifying death for another?
