Mr. Compress recalls back to before the League's encounter with the Meta Liberation Army, when they faced against the Creature Rejection Clan, and Spinner voiced his doubts on Shigaraki's plan for their future. In the present, Mr. Compress uses his Quirk on himself, mutilating his body but being freed from Best Jeanist's grasp, allowing him to compress Spinner and Shigaraki and escape up Gigantomachia's back. He also compresses Skeptic as well as Dabi, who retreated upon defeating Shoto, due to Endeavor being unconscious. Revealing himself to be the great-grandson of the Peerless Thief Oji Harima, Compress frees Spinner and Shigaraki, sacrificing himself to let them flee. At this same time, Deku's head continues to pound away, which he realizes is the Quirk of the fourth user of One For All: Danger Sense. Recalling Shigaraki's words about his stuffed hands giving him disgust and peace, Spinner puts his remaining one on his face, causing him to re-awaken, unleashing a Radio Waves blast that knocks the Heroes away. However, Spinner discovers that All For One has taken control of Shigaraki's body, due to it being on the verge of breaking, and had commanded the Near High-End Nomu to help them escape, leaving behind Compress, Toga, and Machia as punishment for Shigaraki's failure. The remaining Heroes try to attack "Shigaraki" but are all blasted away as the Nomu pick him up and escape. As Deku attempts one last chance to stop him, he too is blasted away, told they will meet again when his body is repaired. With destruction and chaos all over the battlefield, Deku thinks about even after all the terrible things Shigaraki did, when he saw him being overpowered and taken over by All For One, he looked like someone who needed help.

The All For One possessed Shigaraki and his army of Near High-Ends raid Tartarus, the maximum security prison in which the "dregs of society" are thrown in to never be released. They successfully destroy the main gate, killing the guards, and make their way toward the main facility on an island. While flying on a Nomu, Shigaraki attempts to regain control of his body, but his master's will remains stronger, telling him to rest and that he is to become "the next me". Using their shared consciousness, both All For Ones execute dual EMP attacks, shutting down the power in the prison from the inside and out. This results in all the prisoners being let free and proceeding to go on a rampage, which includes Muscular, Moonfish, and Stain; a female prisoner releases Overhaul out of his cell. "Shigaraki" reunites with All For One, declaring to the prisoners to follow him if they want to escape, as it is the start of how he became the greatest "Demon Lord". All For One proceeds to commandeer several air crafts, sending the Nomu and inmates to attack seven other prisons around the country, freeing the prisoners from six of them. "Shigaraki" returns to the League to rest his body, leading Spinner to argue that he intends to follow Shigaraki, not whoever's controlling him, despite his claims that he has the best interests in mind. Two days later, Bakugo awakens at Central Hospital where he learns from his classmates the state of everyone after the War. Gran Torino and Eraser Head are still alive, but in critical condition. Endeavor is taking part in surgery, while the hospital is surrounded by protesters. Shoto recovers from his injuries, resolving that he is the one who has to stop his brother, just as his siblings and mother appear to greet him. While everyone else has regained consciousness, Midoriya still remains in a comatose state, watched over by All Might.
