Boku no Hero Academia (ONA)

The rivalry between Gang Orca's and Shishido's agencies moves onto the field in Hero League Baseball, where using Quirks is perfectly legal and almost nothing else seems forbidden. Just as the chaotic championship game approaches its finish, a villain appears and turns the sporting rivalry into a real hero operation for everyone already on the field.

In another assignment during Deku, Bakugo, and Todoroki's internship under Endeavor, the trio is sent after a vandal called Smiley who covers buildings in doodles. The case seems trivial until he targets Endeavor's own house, and they discover his Quirk forces anyone who meets his eyes into uncontrollable laughter. Catching a criminal has rarely been so difficult for such a ridiculous reason.
