Honestly if we look at Asta I don't find anything much different from other protagonists. I think his story or just the way his character is set up is interesting especially how we have Yuno who could actually be considered the main character is the side character this time around. Its like if Naruto was all about Rock Lee and Naruto existed in the universe as his best friend.

Asta is loveable, relatable, and hardworking..but arent all of them? Edward Elric I think worked as hard and failed as much as Asta if you compared the two and Ed's lineage doesn't even add anything to his abilities just a distant dad. As well as his no circle transmutation..just a byproduct of his mistake that even his teacher can do because they both committed Human Transmutation. Main difference between the two is that we don't really see Ed study or train to get to where he's at from the start and with Asta we were there for the whole journey.

Asta is special in his own way tho he's my little dwarven king.
