The Emperor's Dragon III: Emergence

All For One let his son go see the world, and make his own choices. Perception creates reality. What will Izuku see? A system that should be torn down and burned, or a system that is trying to be better than it is? Which side will he choose? Here, he is not All Might's chosen successor, but All For One's and no matter what he chooses, he will be a force to be reckoned with. AU, DFO
