I would imagine this be quite a ending to Black clover, where the devil would take over Asta and unleash the ultimate spell, of bringing a army of those demon giants from the beginning, and the devil has already overtaken Asta to where he can't control it, and the only other person to save Asta is yuno, but then it turns out the only way to end all of this is to kill Asta and save the world, so yuno would be meant to be the wizard king after all.
Nice
