I have been watching Black Clover for the past couple of months and I can say I love this show. I think the story gives us a view of what a optimistic underdog would look like.
Asta
I absolutely love the fearlessness he presents to the world. Asta has no magick and live in a world with people who has magick.
From the start he is at a disadvantage with a rival who has magick, which makes this rivary somewhat interesting
What he lacks in magick he makes up with his anti magick sword, being that this sword absorbs magick and Asta has no magick only he can wield it.
Hey now that I think about it this sounds awfully familiar
Wow
Both have a source of perceived malevolent hidden deep within
Both were orphan
Both have stuck up rivals
As far as powerless goes i believe his struggle is more of the sames as Midoria in My Heroes Academia
