My gods, Asta...
I remember several times during the early parts of the anime feeling strong compulsions to drop it, on account of the constant "YOU'RE MY RIVAL!" and "YUNO!" and "I'M GONNA BE THE WIZARD KING!".
It was mostly fine as long as Yuno wasn't actually anywhere near Asta, but as soon as he showed up, my ears bled.

Thankfully, as [@Zeroth] said, they eventaully toned it down to... Tolerable... levels. xD
