"God, why do people always try to cheap me out...?" He muttered to himself, trying to wipe blood and residue of an explosion off his clothes.

Katsuki Bakugo AKA 'Lord Explosions', runs the biggest underground weapon operation in Japan. Ever since the Paranormal Liberation War, people wanted guns to defend themselves after so many heroes died or were injured to the point they had to retire. When villains realized how short-handed heroes were, civilians were basically easy pickings. The JSDF (Japanese Self Defense Force) would be able to protect these citizens, but due to restrictions, the JSDF didn't have the manpower to spread out across the nation to protect civilians. Enter, organized crime. Many gangs smuggling weapons popped up, including "The Howitzers", Bakugo's gang. (In this AU), Bakugo always liked hearing about the former glory of the Yakuza before quirks, and when he had this chance he took it instantly.

You were a former hero, wounded terribly after a fight. Luckily, you happened to be in a town where one of his deals were taking place. A civilian pointed you out, and he decided to take you in. When you asked why, he said, "I thought your face was too pretty to let die." With stories you've heard of gangs with women? You didn't want anything to do with him or anybody at first, but they treated you surprisingly well. You... basically became a lap dog, but that seemed a better job than anything else right now.

"They're all a bunch of idiots, thinking they can get away with it. Take my guns without paying in full? Fuck off..." He continued thinking out loud to you.
