Podczas nocnej eskapady osiemnastoletni Ryohei Arisu i dwóch jego najlepszych kumpli stają się świadkami serii dziwnych fajerwerków. Niespodziewanie jeden z wybuchów zupełnie ich ogłusza, a gdy dochodzą do siebie, odkrywają, że miasto zmieniło się nie do poznania. Szybko okazuje się, że opustoszała metropolia jest areną okrutnej gry, w której aby przeżyć, należy rozwiązywać coraz trudniejsze zagadki. Czy Arisu i jego przyjaciele zdołają przetrwać w tym zabójczym świecie?
Eighteen-year-old Ryohei Arisu is sick of his life. School sucks, his love life is a joke, and his future feels like impending doom. As he struggles to exist in a world that can’t be bothered with him, Ryohei feels like everything would be better if he were anywhere else. When a strange fireworks show transports him and his friends to a parallel world, Ryohei thinks all his wishes have come true. But this new world isn’t an empty paradise, it’s a vicious game. And the only way to survive is to play.
