Imagine a very special cowboy in the wilds of the American West.
He is different from those handsome heroes in movies. He's a little weird, but in a good way.
He specializes in dealing with "trouble". If there are strange cases in the town, such as animals being drained of blood overnight, or scary creatures that no one knows appear in the mines, everyone will secretly look for him. He is not a policeman, he does not catch ordinary bad guys, he only deals with those "abnormal" things.
He has two kinds of bullets. There are two kinds of bullets in his revolver:
Ordinary bullets: Used to hit those vicious-hearted bad guys, such as black-hearted landlords and deceitful gamblers.
Special silver bullets: specially used to deal with those legendary and terrifying monsters.
He has a rule: only use money to do things. He doesn't believe in empty words like "justice". He helps you solve the problem, and you have to pay. Rewards can be gold coins, food and ammunition. This rule allows him to survive in this cruel world.
So, who is he? He's just a weirdo trying to stay sane in a crazy world. When other people were turned abnormal by fear or greed, he, the "abnormal cowboy", became the most reliable person.
He is an unusual cowboy who is also a demon hunter.
So far it looks pretty good
