After Shoto defeats Dabi, the dynamics of the battle fundamentally shift in the ninth episode. This news invigorates the heroes. They reinforce their strategy to isolate and defeat the villains one by one. Although Dabi is defeated, a mysterious glow within him suggests he might still be alive.

Amidst these events, Spinner gains a powerful new ability from All for One—the "Body Bulk" Quirk, which transforms him into a giant. Meanwhile, Endeavour and Hawks confront All for One. They recall Hawks' earlier strategy of keeping the team small to minimize the risk of All for One stealing their Quirks. Hawks suspects that destroying All for One's Quirk, which is considered his lifeline, might be the key to victory. However, All for One exploits Endeavour's emotional vulnerability regarding his sons and pushes him to his limits.

During Endeavour's fight, Tokoyami and Jiro join Hawks to support him in battle. Jiro's plan to destroy All for One's mask with his acoustic powers fails. All for One targets him, taking advantage of his inability to fly to mark him as the weakest link. The episode ends in a perilous situation, with Jiro severely injured and Hawks incapacitated. This leaves the heroes in a precarious position against the dominant All for One.
