My Hero Academia

Class 1-A is given a training mission to fight hypothetical villains. It is revealed that Nejire and Tamaki of the Big Three are posing as villains while Mirio plays a civilian in distress. Recovering from his injuries after the battle against the High-End Nomu, Endeavor thinks back to his encounter with the villain Dabi. Meanwhile, Hawks meets Dabi at an isolated warehouse.

Dabi attacks Endeavor and Hawks only to retreat upon the arrival of Mirko. That night, Dabi and Hawks criticize each other for having changed the plan and that it’ll be some time before the latter can meet Shigaraki. Determined to make the world a place for heroes to have some free time, Hawks joined the League of Villains to take them down from the inside.

After discussing his dream with All Might, Midoriya is alarmed that the essence of One For All's previous holders live on within the Quirk. Later that day, Class 1-A and 1-B meet at Field Gamma for their first Joint Training Battle. Both classes are to pair up into groups of 4 vs 4 matches that is commentated by Class 1-B's teacher Vlad King.

The Class A Team is quickly overwhelmed resulting in the capture of both Kirishima and Koda. Improvising a new plan, Kaminari allows himself to be captured, distracting the Class B Team in order for the threat of Shinso's Quirk to destroy their communication, and for Asui to deliver the finishing blows.

After a short break following Match 1, Match 2 begins, with Dark Shadow quickly possessed by Kuroiro. During his internship, Tokoyami was frustrated by Hawks using him just for information, so Tokoyami strove to prove himself as someone to be taken seriously during the work studies.

Against the Quirks of Komori and Fukidashi, the Class A team is divided, with Aoyama captured as a result. Fueled by a desire to surpass Yaoyorozu, Kendo engages her solo. Yaoyorozu manages to launch a bag of support items across Field Gamma to her team. With the aid of thermal goggles, Tokoyami launches an attack on the hidden Class B Team, capturing them.

While the combatants recover, the combat zone is moved to another section of Field Gamma due to all the damage from Class B. All Might wonders about the previous holders as Midoriya and Bakugo discuss what happened in the One For All dream. As Match 3 begins, Tokoyami approaches Todoroki and reminds him that they represent their mentors: the top two heroes

As the endurance match between Todoroki and Tetsutetsu rages on, both combatants begin suffering fatigue, leaving Todoroki no choice but to attempt his father’s signature move. Honenuki and Iida interfere, resulting in the four combatants getting knocked out in the chaos. With the time-limit reached and most of the combatants either imprisoned or incapacitated, Match 3 is a draw.

Creating a plan targeting Bakugo's selfish traits, the Class B Team quickly works to overwhelm Class A, only to be driven back by their perfect teamwork. Bakugo will always seek a perfect victory and that includes not letting a single member of his team fall. In the end, Match 4 finishes in 5 minutes with a victory for Class A. Bakugo awkwardly shrugs off Midoriya and All Might’s compliments.

At Tartarus Prison, All For One oddly hears the voice of his brother which disturbs the guards. All Might is concerned when Gran Torino mentions a previous holder of One For All once told Shimura "the time has not yet come". Enacting his clever trap, Monoma declares Bakugo at fault for All Might’s end causing Midoriya to attack in anger.

Despite the danger of Blackwhip's rampage, Aizawa allows the match continue for the sake of the combatants’ ambitions. Copying One For All, Monoma attempts to attack Uraraka, only for the Quirk to oddly do nothing. Shinso intervenes, unintentionally giving Midoriya a way to engage him. The two begin their rematch, with Shinso pulling two pipes down on Midoriya only to be countered by Blackwhip.

That night, Midoriya and Bakugo spar in Gym Gamma in hope of getting Blackwhip to manifest. Midoriya acknowledges that since he refused to use the Quirk until he better mastered One For All, it won’t manifest until then. Bakugo leaves Midoriya deep in thought after pointing out how One For All has become quite similar to All For One.

While Japan deals with the aftermath of the destruction of Deika City 9 days earlier, Midoriya and the other students of Class 1-A begin interview training. Visualizing unlocking One For All, Midoriya is able to properly manifest a little of Blackwhip for just a second. Meanwhile, All Might begins researching what he can of One For All’s previous holders.

A few weeks earlier, Hawks is given another chance by Dabi to join the League of Villains and visits Best Jeanist to check on his recovery, pulling a feather blade on the hero when his back is turned. After celebrating New Year's with his mother, Midoriya heads off to begin his work studies.

With Hawks’ message in hand, Endeavor now understands the true reason behind the Hero Public Safety Commission bringing back the Work Study program: to ensure everyone is ready for the forthcoming attack of Shigaraki and his combined forces. Accepting Midoriya and Bakugo as his students, Endeavor first seeks to understand what each has to work on.

The Oki Mariner Crew is pursuing a ship carrying chemicals used to make an illegal Quirk Booster drug. Due to the difficult situation, Selkie requests a team up with the Ryukyu agency. Ryukyu, Uraraka, Asui, and Nejire arrive, and Selkie has the young heroes relax on the beach for the day to boost their morale. The heroes take to the ocean while the smugglers attempt another escape.

A week into the work studies, Endeavor gets a call from Fuyumi who suggests bringing the trio home for dinner. The dinner soon gets uncomfortable as the conversation switches from being about Fuyumi's cooking to how Endeavor prevented Todoroki from eating Natsuo's cooking. A disgruntled Natsuo soon gets up and leaves. Midoriya and Bakugo overhear Todoroki and Fuyumi talking about everything.

Fuyumi explains to Midoriya and Bakugo that Natsuo was very close to Toya, causing him to blame Endeavor for his brother's death. Eventually the time comes for Endeavor to bring the trio back to U.A. The car is soon attacked by street whitelines, controlled by a villain named "Ending", with Natsuo held hostage.

While Class 1-A celebrates the start of the third semester, Aizawa and Present Mic are summoned to Tartarus Prison by Detective Tsukauchi and Gran Torino. There, the two learn that Kurogiri is a Nomu created using the corpse of their school friend Oboro Shirakumo. Aizawa and Mic are asked to talk to Kurogiri in the hopes of getting information about the League of Villains.

Two months earlier, Gigantomachia appears before the League of Villains, declaring Shigaraki unworthy of being All For One's successor. During the attack, the League is teleported to the lab of All For One's assistant, Dr. Ujiko. The Doctor intends to help Shigaraki in his goal of destroying everything that irritates him, but before Shigaraki can be granted power, he must defeat Gigantomachia.

Deika City's welcoming party for the League quickly turns into an ambush, causing everyone to get separated. Toga is soon surrounded by Curious and her supporters. Intending to understand why Toga is the way she is, including why she attacked and drank the blood of a classmate in middle school, Curious overwhelms Toga with her explosive arsenal.

Captured, Twice can do nothing as Skeptic's puppets attempt to snap Toga's neck. Faced with the pain of his arms being broken, Twice finally realizes he is not a double and unleashes thousands of doubles of himself. Determined to not let his friends die, the Twice doubles swarm Deika City, helping to turn the tide in the League's favor.

Re-Destro overwhelms Shigaraki, destroying his left hand and the hands he wears all over his body, causing him to experience flashes of his deceased family. As a child, Tenko Shimura (Shigaraki) lives under the one harsh rule of his father Kotaro: never talk about heroes, as they do nothing but hurt their own families to help strangers.

Ignored by bystanders, Tenko wandered the city streets alone, hoping for a helping hand, which he got in All For One. Thus, Tenko was slowly groomed into the villain he is today: Tomura Shigaraki. Back in the present, consumed with a sense of freedom, Shigaraki unleashes the full power of his Quirk, turning Deika City into nothing but a crater.

Hawks, undercover within the Paranormal Liberation Front, has put all the pieces together except for one: Shigaraki's sponsor Dr. Ujiko. Meanwhile, Ujiko begins performing the experiments necessary to give Shigaraki power that will let him surpass All For One and obtain One For All. Back in the present, Class 1-A shows off the new abilities and skills that they learned in their work studies.
