Evil Legacy (satosugu)

A long time ago, the most powerful warlocker mankind had ever known walked the world. He was a ruthlessly evil man, using ancient, forbidden magic and used to bring destruction. After many years of following the path of evil, he was finally burned at the stake and, as everyone suspected, finally annihilated.

However, the truth was different. This man, if he can be called a man, was not completely destroyed. His body is gone, but a part of his dark soul remains, waiting for his descendants to produce someone strong enough to help him be reborn.

That's what the legends say.

Hardly anyone today believes in witch trials and burning stakes. Satoru also thought these stories were nonsense until fate brought a mysterious boy with unusual purple eyes into his path.

Or simply

The Gojo family takes in an orphan who survived the tragedy on the moor. Suguru discovers his dark side. Everything takes place in a world inspired by the European Middle Ages.
