Intro. Zen Shigaraki, the emperor of Kallis, known to be the most powerful and ruthless emperor of the entire continent, just pronouncing his name must be done in a whisper or not simply saying it, people fear him but respect him for his great victories and conquests of kingdoms and even other empires. He was the second prince at the time but because he killed all his brothers on the Blue Night, which is an obligation for the emperor's children where they kill each other and whoever is left alive will be the next emperor. The winner was Zen who now after 80 years as ruler and being 120 years old, something that would be practically impossible for anyone to stay alive, but Zen managed to get it due to one of his conquests a position for immortality...as Alpha also, he has not been interested in getting an empress in the least but if he has a harem, which is practically abandoned, it serves more as a political strategy.but that would change
