The SSS Ranked Demon King Goes to the Hero Academy

Aku was not the hero destined to save the world, nor the princess destined to be rescued.

He was the demon king. Born without a name, without form, without freedom, predestined to die at the hands of the hero from his birth.

However, Aku decided to defy fate. He took over the hero's body to find his freedom.

It was then that an angel spoke to him, believing he was the hero who had failed to defeat the demon king.

The angel told him that countless worlds and countless demon kings existed; those heroes who failed their mission were sent to an academy to amend their mistake.

Now Aku will find himself caught up in battles with other demon kings and wars in other worlds while deciding whether to choose the path of good or allow himself to be consumed by darkness.
