A world-ending digital threat, a demon who'll stop at nothing, and Levi Jensen's final play... Shiho Hidetaka has gone to Japan to investigate her father's disappearance. Before he vanished, he was working on a mysterious project, codename: "Draupnir", which is set to rewrite not only the digital realm but reality itself. As dark forces seek to take possession of Draupnir, Shiho finds herself caught in a deadly web of intrigue for which she is unprepared. Unable to trust anyone-least of all herself-her only hope rests with Levi Jensen. But as Levi and his friends are drawn into a world of espionage, deception, and science fiction, he must come face to face with an enemy beyond anything he has faced before. It's time to play the Demon's Game. Demon's Game is the fourth instalment in the subversive GameLit series Levi's Game, blending science fiction, horror, and dark fantasy, exploring the boundaries of imagination and the courage of those who defy reality.
