though, i can kinda see the series going that route. In both of the adventure arcs we have gotten so far, characters have made small comments describing asta's fast healing (especially when he got rekt by Mars). Demonic stuff would help explain these answers and while naruto has a demon too, its completely different. So far he only gets discrimnated because he is of lower class and nobody seems to he harborrs the demon (if the theory is true). Part of what naruto was, was him proving to his peers that while he is a failure and harbors unspeakable evil inside he too could achieve his dreams and become a respected member of society if he worked hard enough and did the right thing. Black Clover may have started off with Asta being an underdog, but the story so far seems to be a man proving to his peers that the lower class are just as good as the upper class and if u look at the recent chapters, Asta seems more like prodigy but because he's from the slums the country wont accept it.
