Warlock: The Magical Hero

Izuku was gifted something special, a power to save the world, a power unlike any other person's. However unlike another dimension, it's not a Quirk given by All Might but Magic given by an interuniversal being from another plane of existence so he can save the world from an ancient undead. So yeah, pretty important power he's got there. Semi-crossover with D&D. Rating may change.
