In this story, after being tormented by his friends and sister for being quirkless, Izuku Midoriya is killed by the sludge villian, and makes a deal with the demon lord Beelzebub, keeper of the hellhounds. Izuku agrees to be alpha over them so the demon lord can have a break, in exchange to live on earth and become a hero. I do not own MHA, just the concept and story.
