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.

All Might's last fight against All For One set off a series of events leading to his retirement as a hero, but he continues to fight, even as the embers of One For All within him die out.

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.
