The Todorokis reminisce on their past history that led them to this moment. Enji and Rei had discovered that while Toya possessed a fire Quirk greater than his father's, he had his mother's constitution, making him resistant to ice but weak to his own fire. In an attempt to protect him, Enji ceased all training with Toya, but when that refused to deter him, he decided to have more kids to make him lose his resolve. After Natsuo's birth, Shoto is born with the Quirk combination Enji desired, to his joy and Toya's devastation. After an incident where Toya had a breakdown and nearly attacked Shoto, Enji banned all interaction between Shoto and the other siblings. By the time he was 13, Toya continued to grow more emotionally distraught with his siblings and mothers, while also training his Quirk to the point his fire grew from red to blue. He wanted to show his father his progress, but upon the realization he had continued his training, a furious Enji took his anger out on Rei. This reached her breaking point, resulting in the incident of Shoto's burning and her hospitalization, followed shortly after by Toya's supposed death as his Quirk went overload and burned the entire mountain down. In the present, Rei declares to Endeavor that he isn't the one suffering the most, and they all carry a small weight in Toya's downfall, so they will help deal with him together. Hawks and Best Jeanist then arrive, telling Endeavor about the current state of the world and requesting a team-up to help solve their problems together. Hawks then asks him about "One For All", as Endeavor's mention of it during the battle with Shigaraki has spread to the public asking questions, leading him to tell them about Midoriya. Meanwhile, All Might continues to watch over Midoriya alone, knowing he is currently having a conversation with the predecessors of One For All.

Ketsubutsu Academy third-years Yo and Tatami enter a nearly abandoned city in order to evacuate the remaining civilians, having received reports of a jailbreaker causing destruction nearby. Yo attempts to convince them, but they refuse, no longer trusting in Heroes and believing they can fend off danger and protect themselves. Shortly after they encounter the aforementioned jailbreaker, Muscular, who Yo attempts to fight off while Tatami goes to protect the civilians. Yo is pinned down, but even after using his Quirk at full power, Muscular has the upper hand and nearly kills him, until a hooded Deku, covered in purple smoke, appears to save him. Muscular recognizes him from their fight in the forest and excitingly prepares to fight him. Deku hands the unconscious Yo to Tatami and re-enters the fight. The sixth user, En, warns him to not overuse his Quirk, Smokescreen, as Deku uses his new arsenal of abilities and experience to get the upper hand on Muscular. He attempts to reason with him, asking him why he causes trouble and even referring to him by his real name, but Muscular declares all he cares for is wanton destruction. Taking advantage of his muscle fibres being damaged by Yo, Deku punches him with a Detroit Smash, knocking him unconscious. While Deku brings Muscular to prison, the civilians agree to evacuate with the Ketsubutsu students, not wanting anyone else to get hurt. Deku temporarily reunites with All Might before heading off to deal with the next threat. Several days prior at the hospital, Izuku awoke to learn the injuries on his body were not as fatal as they initially believed due to his increased in strength in his body. He and All Might then tell Inko the truth behind One For All, with Izuku saying he won't be returning to U.A. in order to protect everyone with Shigaraki targeting him. He comforts his tearful mother telling her he will return to her, with All Might saying he will stay by his side. They decide to team up with Endeavor, Hawks, and Best Jeanist, using Izuku as bait to lure the villains out of hiding. Before leaving the hospital, Izuku visits Gran Torino who tells him killing can be a way to save, and hands him his scarf to wear.
