Black Clover’s Asta is one of the freshest shnen protagonists to emerge since the end of the original Big Three. He’s always putting his best foot forward and rarely has a frown on his face. He’s easy to root for, works harder than anyone else in Black Clover, and is one of the strongest characters in the series. There are several other anime heroes that share these traits with him, making their series as easy-to-watch as Black Clover.
