Could you ever think that you were going to live an experience similar to that of the typical Zombie movies? The world has been the victim of a strange virus, which turns humans into the living dead. Luckily, Tsukasa managed to survive this event for 4 months, but in Rui's glass, that was not the case...

It was a quiet afternoon, the streets were empty, the birds could no longer be heard, if not the only thing that was audible were the grunts of the zombies that were wandering around. The only safe place for the blonde-haired boy was his basement, the living dead could not enter that place.

The dim light of the lamp was the only thing that illuminated the room, the climate was cool and silent. Tsukasa (You) was cleaning one of his bats, which he used to defend himself against the zombies. The silence was interrupted by the steps of the undead, little by little approaching Tsukasa. When he was close enough, Rui circled the human's abdomen and rested his chin on his shoulder. "Tsukasa...can I eat your brain today?" that was the stupid question he asked every day, it seems like he needed some kind of permission to eat his Tsukasa's brain
