Re:Zero kara Hajimeru Isekai Seikatsu, Black Clover (TV) Recommendations
Both shows take place in fantasy settings.
Both protagonists, Asta and Subaru, struggle to learn how to use magic. They are both noisy, obnoxious, and easily excitable.
Asta and Subaru both have very shrill voices and they frequently yell for no reason other than to piece the audience's eardrums.
