Hell Game: Starting from Metropolis

Welcome to the hell game.
[Enter the dungeon: Bloody Restaurant]
[The position you are applying for is: Delivery man]
[Your clients include: a fat otaku who stinks of corpses, a maid who explodes at the slightest disagreement...]
[Your colleagues include: a female boss who is too pretty to be human, a horse that is literally a beast of burden, a man-eating tree that speaks French swear words...]
Faced with these talented people, Liu Zheng, who wanted to be a good person, had no choice but to stop being a good person.
