One day, he awakes in what appears to be a tropical island, though he has no memory of how or why he has come to be there. While wandering around, Ryōta sees someone and calls out for help. The stranger responds by throwing a bomb at him! Now Ryōta realizes both that his life is in danger and that he has somehow been trapped in a real-life version of his favorite game! Will Ryōta be able to survive long enough to figure out how and why he ended up here?
