Since All Might used the final embers of One For All at the Kamino Incident, he’s had a smaller role as a hero since. However, during My Hero Academia’s final war, All Might has assumed the grand responsibility of distracting his former nemesis, All For One, until Deku can defeat Shigaraki. Without a Quirk, All Might’s Herculean task seems all but impossible, but he’s reminding fans just how he came to be the greatest hero by standing up to the Demon Lord with the help of a support item.
