The Obedience Hero: Zero

As a young boy, Izuku Midoriya-Yagi learned many things about the world, that tainted his world view. Nobody is born equal, and that fairness was a concept. Izuku would come home from his elementary and middle school constantly with new marks and scars from his abuse from people who were once his friends, while only his mother paid any attention to said wounds. His father, paid no mind, while his sister was actively participating in his abuse.

Time passed by, and Izuku became 14, and he looked like any old middle schooler, but under his uniform, he was scarred completely. How will things change when a man who was one of his few friends ends up changing his life, by granting him a blessing in the form of a terrifying curse?
