The "Hero League Baseball" is an organization set-up by several Pro Heroes to allow them the chance to play and compete in their spare time. For this year, the "Orcas", led by Gang Orca, and the "Lionels", led by Shishido, have made it to the finals. Present Mic narrates the game, accompanied by an extremely apathetic Eraser Head.

It's been ten months since Izuku en-rolled at U.A. High School, and on top of his regular school work, four days a week he has been continuing his Hero Work-Study at the Endeavor Agency. On one day, they are approached by a police officer, seeking assistance in tracking down a local graffiti artist vandalizing the streets.

Class 1-A are bored out of their minds! Stuck in their dorms during the winter season, they can't go out or do anything fun. That is until third year Mirio Togata pays the students a visit with a new card game the support course developed that uses U.A. students as playable characters. Now to pass the time, they'll play this game that's just as tough as U.A. Who will win the card battle?!

After the Quirkless Izuku Midoriya meets All Might, he becomes the successor to All Might's Quirk, One For All, which means he must eventually go up against All For One and Tomura Shigaraki.

Ochaco and the Todoroki family think back about why they are fighting and reconfirm their convictions as they continue to face off against the villains.

When Tomura Shigaraki was a child, a tragic accident led to the death of his family, which continues to fuel his desire to destroy.
