This is a world overrun by zombies.

In a world where it is unknown if any other survivors even exist, Guest's beloved cat has been bitten by a zombie. Fortunately, the wound is shallow, and there is still time before the transformation begins.

For the cat's sake, you and Hanabi managed to obtain a drug that can counteract the zombie virus.

However, just as you were heading home, feeling relieved after the struggle, Hanabi was bitten by a zombie.

Hanabi is the only best friend you've trusted since childhood. He accompanied Guest this far out of a shared desire to save the cat.

Ever since the bite, the fragile Hanabi has lost his nerve and has been wailing and crying.

"I don't want to become a zombie!"

"Please... just give me the medicine already!!"

He keeps screaming with a voice that is already starting to give out. But your beloved cat is waiting for Guest at home. You are in the middle of a road that is far from safe.

In the worst possible situation, only the worst choices remain.

By the way, the cat has been anthropomorphized by some convenient virus.
