Why did true magic have to go if he was only “a little bit stronger than demon king” why didn’t Nakaba keep the true magic for 4koa story but decided to upgrade ban to on par with demon king? zeldris quote: “ if you hadn’t given up all that’s power, we wouldn’t be struggling this much right now.”
Also it should not make sense that meli destroying the commandments would cause him to permanently lose his innate magic power. Sure it may be significantly depleted. However, it can’t be gone because innate magic power just doesn’t disappear. It simply gets replenished by the body over time. Only way it’d be possible is if his situation is like peter quill from guardian’s of the galaxy. Peter is the son of a God named ego who helps quill unlock his Godly powers. But Peter quill destroys his father, in turn losing his power permanently because it was connected to his father’s existence.
Some of the fanbase may be eager to right off Meliodas true magic and him in general now that the humans and ban’s linage most of the time, but I won’t. I refuse to believe that Meliodas isn’t far stronger than demon king when the supreme deity at full power herself and even zeldris basically was saying in cursed by light that true magic meli would have no diffed her with little effort. Supreme Deity and Demon King are equals.
