My Quirk is Never Giving Up!! (MHA x Black Clover)

It appeared as though humanity would be destroyed by the demon. But, a single person saved them all. He became a legend, and was known as the wizard king. Many generations later, magic has disappeared, and then reappeared as superpowers known as quirks. Izuku Midoriya was a part of the small population that had no power. But, in an odd encounter in the forest, he'll find power of his own and become the best hero in the world.
