The episode begins with a brief recap of the strategy to divide the villain team. Midoriya leads the fight against Shigaraki, while Endeavor's team faces All for One, and Todoroki, alongside Endeavor's sidekicks, battles Dabi's flames.

At another front, Himiko Toga is isolated on an island and attacked by Uraraka, Tsuyu, and other experienced fighters. In the "Sky Coffin," Shigaraki reveals that his surprise attack is due to his physical evolution, not a new Quirk. Midoriya asks Eraser Head for help with a warp gate but is instructed to return alone to avoid the risk of Shigaraki's Decay ability.

On Okuto Island, the hero team splits its attention between fighting Nomus and confronting Himiko. Himiko, confessing her love for Midoriya, attacks him, expressing her desire to become like him. Midoriya reacts confusedly to her feelings, leading Himiko to realize that Midoriya, like others, is different from her. Enraged, she attacks at full strength. Midoriya's powers fail against Himiko, as her genuine affection is not perceived as a threat by One for All.

Uraraka and Tsuyu intervene, with Uraraka getting wounded. Their support allows Midoriya to fly toward the "Sky Coffin." Along the way, he considers using the Meta Ability of the second One for All user, Kudo. Kudo appears and explains that Gearshift has evolved due to One for All's accumulation effect, advising against using it under normal circumstances. He urges Midoriya to trust his friends and focus on his own battlefield.

Meanwhile, Dabi unleashes chaos with his flames. Amid the battle, Todoroki confronts Dabi, asking why he didn't return to the family if he survived. Dabi responds, revealing his identity and promising to explain how he became who he is now.
