In the gymnasium, Class 1-A is making their final preparations for their musical performance before the day of the school festival, with Mina working hard to have the dance choreograph precisely. In Heights Alliance, some of the students cannot sleep from how nervous and excited they are. Meanwhile, Izuku is again training with All Might when a scruffy Mei shows up and gives him the support equipment he requested: a pair of Air Force Gloves. She also made sure the design went with Izuku's hero costume. Izuku thanks her for making the gloves, and All Might is impressed by how compact they are. Izuku does the last minute preparations for the school festival and the chance to see Eri's smile. But he unexpectedly runs into Gentle and La Brava, who plan to begin their assault then. He recognizes them from the videos he is seen online, and both Gentle and La Brava recognizes Izuku from the sports festival. To prevent the school fest from being cancelled, Izuku decides to defeat them solo before the festival begins. Note: Due to the COVID-19 pandemic, Funimation did a disclaimer at the beginning of the episode stating that the English dub voice actors were able to record their lines from the safety of their homes. This disclaimer was present for the remaining episodes of this season.

As the school festival was about to begin, Izuku faces off against Gentle Criminal, who proves an even match with his Elasticity Quirk. Using ranged attacks, he is able to subdue the two villains. Despite his efforts, Gentle cannot break free of Izuku's grasp. Seeing this, La Brava begins to remember her past. Gentle accepted her for who she was, and when he decided to team up with her he gave her the name of La Brava. Back at present, after whispering that La Brava loves Gentle so much, she uses her Love Quirk to temporarily strengthen him and nearly overwhelms Izuku. As the battle with Gentle continues, Izuku is determined to save the festival especially Eri's heart; La Brava pulls out her laptop and runs off to hack the security system, but she is out of range and tries to proceed further and she notices Hound Dog and several clones of Ectoplasm close by. Izuku ends the fight by taking down Gentle with a St. Louis Smash, as La Brava's Quirk expires. As Izuku apprehends them and Hound Dog catches their scent, Gentle sends Izuku away, surrendering to him and Ectoplasm in an attempt to cover for La Brava.

Gentle Criminal accepts defeat and is apprehended by Hound Dog and Ectoplasm. Izuku rushes to retrieve his supplies with help from one of Ectoplasm's clones and rejoin the festival in time. He makes it in time for Class 1-A to do their concert, with Jiro doing a performance of her original song, "Hero too" with the help from the class. The performance is loved by all, including Eri, who smiles for the first time in her life. The school festival continues with Class 1-B putting on its stage play with the audience enjoying it despite being a mishmash of several famous works. At the beauty pageant, the participants battle it out for the title, with Nejire takes the victory after gaining the most votes while the two-time winner Bibimi Kenranzaki of Class 3-G humbly accepting her defeat. As the festival comes to a close, Eri feels a little sad as she was about to leave until Izuku gives her a favorite food that she wants: a homemade candy apple, where he had cooked himself much to Eri's glee. Izuku waves goodbye to them as Aizawa and Mirio escort Eri back to the hospital. In the post-credits scene, La Brava and Gentle are offered chances to redeem themselves by the police where La Brava is interrogated by two police detectives while Gentle Criminal is interrogated by the gorilla detective Gori. When Gori asks if he would like some tea, Gentle Criminal states that he will take earl grey. Gori states that he will get whatever tea they have.

Also, Mirio reveals that Eri's horn is the source of her Rewind Quirk, and has started to grow a bit. Meanwhile, the Wild Wild Pussycats along with Kota, visits Class 1-A. Izuku greets Kota, mentioning that he still keeps the letter that he wrote to him. Mandalay shows Izuku the new shoes Kota bought which are the exact same kind of red shoes he wears, much to Kota's embarrassment. Elsewhere, the first Japanese Hero Billboard Chart since All Might's retirement begins its broadcast from Kamino Ward. The new Number One Hero is revealed to be Endeavor. Meanwhile, Dabi sends an intelligent High-End Nomu named Hood to hunt down Endeavor, along with Hawks, the new number 2 hero, whom he had a meeting about the future of hero society. As the two had finished their conversation, Hood suddenly crashes through the glass windows and Endeavor challenges the creature to face him.

Though severely wounded, Endeavor imitates All Might's pose which is a sign of his start, as onlookers cheer for him. In a post-credits scene, Izuku has a mysterious dream where he encounters the previous users of One For All, including the first, who is the younger brother of All For One.
