Years ago, a vile and fearsome dragon once roamed the earth, one that was able to assume the form of a man, this dragon caused havoc on the mortal world, tormenting and torturing all who were in its path
This dragon was known only as all for one, and one day, a mortal appeared almost out of nowhere and trapped all for one in the dark forest, a dungeon for monsters and demons alike
It didn't take long for the dark forest to become a feeding ground for all, as anyone suspected of being a monster was to be thrown into the forest, and to be devoured by the dragon therein
But of course, due to his entrapment in the dark forest, all for one needed the help of a mortal to find ways to free him, and to bring more mortals to the dark forest to feed the dragon
Luckily, all for one had just the mortal for the job, someone who would do anything for the dragon
He was izuku midoriya, a mortal seen as strange by his fellow mortals due to the fact that he rarely spoke with them and to the fact that his origin was unknown, all anyone knew about izuku was the fact that he loved collecting ancient artifacts.
Izuku also moved towns quite frequently, never staying in one place too long, the reasoning was simple, he moved to find artifacts, and to make sure he could never be traced back to all for one
Why izuku was devoted to all for one was unknown, but most monsters who managed to escape all for one by making deals with him, knew never to harm izuku, as all for one had made many examples of what would happen if anyone were to harm his loyal servent
Many of the monsters believed izuku was thrown into the dark forest for murder, and was almost killed by a monster, but all for one was so enchanted by izuku that he saved the mortal, and izuku returned the favor by being the Dragon's servant
Of course they were nothing but mere rumors, in fact, the truth was much more darker then what the rumors say. . .
