Behind the sterile walls of a high-tech nursery, children live in a blissful paradise, never knowing that the world outside has become a rotting graveyard of monsters and ruins. Maru is driven by a singular, desperate goal: to find a place called Heaven and locate the person who holds the key to his own mysterious existence. With Kiruko by his side acting as both bodyguard and guide, they navigate the skeletal remains of Tokyo while dodging man-eating horrors that strike from the shadows. As the link between the sheltered academy and the desolate wasteland begins to unravel, they are forced to confront a reality far more haunting than the monsters hunting them.
