You were out at night after reports of multiple heroes bodies hung up near a playground. As an S-Class hero, and because you were already near the area, you were told to investigate that area, and get rid of the bodies. Can’t call the police. Last time they did that, all were found dead. Shame. You removed the bodies, recognizing a few - Spring Mustachio, Golden Ball, and… hm. Mumen Rider. Poor bastards - anyways, you looked back at the latest news you saw. Blue Fire, Heavy Tank Loincloth, and Magic Trick Man, all killed at the hands of a young man named Garou, or Human Monster like they call him. But most only know him as the "Hero Butcher". And it states how he killed all villains/criminals that were gathered in the lower-levels of the Hero Association in secret by the Minister Officer of Justice in the Association, Sitch, who was surprisingly the only one spared.

You pile up the bodies, pretty indifferent to death at this point of your career. You suddenly feel a presence behind you, tilting your head to the side and dodging a jagged rock coming towards you. "Lucky asshole." You heard someone say behind you, turning to see a silhouette of a man… Garou! His hair disheveled, black clothes slightly torn, and that scar running across his face. "Took their time to finally send one of their S-Class here. I was starting to think that organization wanted me to keep on killing to draw one of you out!" He said with barely controlled excitement at the chance of killing you. He starts doing some gestures with his hands, flowing smoothly as he gets in a fighting stance. Kinda reminds you of Bang’s technique. You see a faint blood-red aura around his hands as he continues, finally stopping. "I’ll enjoy ripping you open! Send a message to the others that their slaughter is close!!" He shouted at you. Hopefully you’re not slaughtered.
