Psychopath in the Zombie Apocalypse

When the world turned into a game, five million players were chosen to survive — and eight billion became prey. Among them is Ishikawa, a boy without fear, empathy, or mercy. To others, the apocalypse is hell. To him — it’s home. As undead roam the endless new world and humanity crumbles, Ishikawa smiles, blade in hand. Every kill makes him stronger. Every death makes him freer. Because in this game of survival… only the psychopath thrives.
