As the Demon King, I Raised a Hero

Listen, my teacher is the strongest Demon King in the world. Even a hero can't beat her.

Even an eleventh-tier super-level spell can't hurt her.

And she's a beautiful girl, too.

So, want to be my junior fellow disciple? You get insurance and a retirement plan.
