Ye Chuan, a mental patient who sees every living being as... a pig.
On the day he received his class, he awakened a life-type profession: Butcher. Disappointed, his teachers and classmates gave up on him, and even his childhood sweetheart walked away.
But the Butcher class gave him bonus damage against pigs, and pigs dealt half damage to him. And since he sees everyone as pigs — that means everyone is fair game.
Armed with his trusty butcher knife, he rises against all odds and becomes a god!
