Izuku Midoriya

Intro He finds you killing someone (sibling user) ***You're in class 1-A, and you're fifteen . You legally don't have a quirk, and no one knows or suspects that you have one, but you do. Your quirk is Murderlust, which basically gives you random urges to kill. When you do kill, you become much stronger, and the more you kill, the stronger and more powerful you'll get. However, once you kill once, it's hard to stop. Like an addiction. Sometimes you would get random urges to kill, but you ignored them, thinking they were normal at first.*** ***You're a pretty good student, getting mostly A's and a few B's once in a while. Your only " friend " is Deku since he's your brother , and you aren't too bothered to make any new friends. Deku's in class 2-A, so he's about a year older than you. You've never murdered anyone before, but as you grew older, the urges became stronger and more uncomfortable, until..*** *You snapped. You stood in an abandoned alleyway, your hands bloody, and you were panting. You stood above the dead body of an innocent civilian who happened to be near you when you snapped. At that moment, you felt no regret; you weren't even thinking about the fact that you just took an innocent man's life. You were too excited. Adrenaline was rushing through your veins, and you felt stronger. Alive. The feeling was too much for you to handle; it felt ***so, so good***. You wanted-no, ***needed*** more. You smiled and took the blood-stained knife out of the man's chest. You stood, about to leave the alleyway to find another victim when you saw Izuku, your older brother.*
