Template:Eijiro Synopsis/Final Act

Dark Hero Arc
A few days after Izuku left U.A., Eijiro is later seen at a meeting with Class 1-A. He and Class 1-A deduce that Izuku is now working with Endeavor and his team. Eijiro wonders how will they get to contact the heroes who possibly know the whereabouts of Izuku, and Ochaco suggests to push their issue forward. A few days later, impatient with their response, Class 1-A use Endeavor's U.A. Alumni status to confront him despite knowing how much he does not like to be tricked.

Once Principal Nezu gives Class 1-A permission to bring back Izuku to U.A, Eijiro joins with his class to search for Izuku while at the same time, apprehending any prison escapees along the way. After a month of trailing in Izuku's whereabouts, Class 1-A finally arrived on the scene to defeat Dictator. When Izuku refuses to yield, he demands everyone to get out of his way, which means they might have to fight him to surrender.

Eijiro stays on the sidelines to secure Dictator along with Yuga and Toru until Endeavor arrives to arrest him. He tells him that even though he can't do much right now with how fast paced the current battle is, he has a lot to say to Izuku, before heading off on Endeavor's orders to make sure if there are any other anti-hero civilians in the area.

After saving Izuku and Tenya from the fall, Eijiro shouts to Izuku about remembering a story from a while back about a kid who rushed in to save his friend, realizing it was him, and that what he did back then is what they're doing now. He then listens to Katsuki apologizing to Izuku before he collapses from shock and exhaustion, as the class escorts him back safely to a heavily fortified U.A High where they are confronted by angry protesting civilians.

The civilians are distressed because they are aware that Tomura is targeting Izuku and him being there at U.A. will put them in danger too. Everyone tries to reassure them but to no avail, until Ochaco floats her way up to the top of the building, shouting down to everyone and giving an impassioned speech to let Izuku stay. With all this, the civilians agree to let Izuku stay, and the class proceed to escort him inside.

The boys immediately rush Izuku to the bath, stripping and washing him down before getting in themselves. Afterwards, Class 1-A is visited by All Might, where he and Izuku apologize and make up before he heads back out. With Izuku finally passing out and getting some rest, Class 1-A comes back together, as they declare they won't just bring the world back to how it was, but to make it a better place than before, and do it all together.

U.A. Traitor Arc
Two days later, Class 1-A learn that during this time, Tomura had fought American No. 1 Hero, Star and Stripe, and while she was killed during the battle with Tomura successfully stealing her Quirk, New Order, thanks to her actions, the Quirk acted like a virus within his body, destroying several of his Quirks and delaying his procedure by about a week. All Might informs all this to the class, telling them that this is now their perfect time to prepare for the inevitable all-out war. The class reveals over the past month they had been training with the Wild, Wild Pussycats in order to keep up with Izuku in the incoming conflict, and are now about to head out to continue their training.

The class train amongst themselves in the courtyard, where they discuss about their plans for the incoming conflict. Shortly after this, Eijiro and the rest of the class receive the devastating news that Izuku had just captured the Aoyama Family, learning that they have been spies for All For One, and Yuga was the traitor who isolated the class at the U.S.J. and revealed the location of their training camp. Restraining them in the AV room, he and the other class members refuse to back down from the news despite Nezu's request, all in stunned and tears of Yuga's betrayal. Eijiro himself begs Yuga to tell them it was all just a lie. He listens to Yuga's desperation that drove him to despair, followed by Izuku's pleading to let Yuga still help them.

The rest of the class quickly realize that they could have Yuga help deceive All For One and "steer the villains" into the fight, and when questioned why they're so willing to trust him, Tenya simply responds that what happened is in the past, and with them being unable to realize how he's been feeling all this time, they carry some responsibility, so they must reach out to him as friends in order for them to become equals again. Eijiro shouts that he knows Yuga thought it would be impossible to go against All For One, but now Izuku has given him and his parents a chance to finally break free from him, reminding him that they would never blame someone for being Quirkless, or would hate them for holding back their tears and hiding their pain in secret.

Shota then appears on a tablet screen, taking full responsibility and reveals that he has an idea, which Class 1-A, the U.A. Staff, and Police Force hear while the Aoyama Family's ears have been covered. Naomasa then has the Aoyama Family escorted back to their HQ, telling everyone not to say a word to anyone else about the plan, while he and the rest of the class look on sullenly.

Back at Heights Alliance, Class 1-A take a breather, before getting ready to gear back up, as everyone, with fire and rage in their eyes over the betrayal, prepare to bring All For One down once and for all. Eijiro and his classmates form their "Search Squad" and head out to hunt the villains.

Later that night the class returns to Heights Alliance to rest after coming up with nothing from their search. Just then, All Might, Naomasa, and Nezu arrive to inform them all about their secret finalized plans for the upcoming Second War. They bring in Hitoshi Shinso, to the class' excitement, learning that he has trained his Quirk to be able to get people to talk, and they will use this ability to allow the Aoyamas to deceive All For One. The class, including Eijiro, further cheers on Hitoshi, as well as Shota learning that he had trained him.

The next day, Nezu announces to the civilians that Tomura will make his big move in 4 days, with Class 1-A moving outside of the U.A. barrier to began prioritizing their safety. After saying their goodbyes, Eijiro and his classmates move into the upgraded makeshift fortress called "Troy". After settling in, he, Katsuki, and Tenya go to check in on Shoto to see how he is feeling about his impending confrontation with Dabi.

Final War Arc
While the majority of his classmates and the Pro Heroes are assigned to face off against the major generals of the Paranormal Liberation Front, Eijiro is sent on a team led by Mt. Lady, which includes Mina, Minoru, and several 1-B students, to the ruins of the Jaku General Hospital, where Gigantomachia's Detainment Facility is stationed. Their plan is to defend it from the villains which they believe will try to attack and free the beast.

Sure enough, a subsection of the Paranormal Liberation Front attacks with the Heroes present putting up a fight. They also receive word that Shoto managed to defeat Dabi, giving them all the inspiration to continue to do their best. Right as Mina ends up encountering the villain who killed Midnight, taunting about how he'll run them all into the ground just like he did her, Eijiro arrives, stating the area's been properly secured, and after Shoto showed them how manly he was, they have to do their part now, ready to back Mina up.

While the team is able to take out most of the threats, several Villains are able to escape into the air using their Quirks, and using an ultra-high frequency emitter to broadcast All For One's voice, successfully re-awaken Gigantomachia, who promptly breaks free from his containment. Facing impending destruction, Eijiro races across the battlefield to find Hitoshi, as he had been warped to their location in case of an emergency, as he had helped him evade the Villains' detection at the start of the battle.

He reaches Hitoshi's hiding spot, telling him to brainwash Machia, however, he is shocked to find him currently being absorbed by the Sludge Villain, who gleefully taunts him. Eijiro tries everything he can to get Hitoshi free, but the Sludge is too much for him to deal with as Hitoshi continues to be consumed by the Villain.

However, Mina arrives just in time, using her Acid at max velocity, shoving her hand inside of the Sludge Villain, causing the Acid to mix in with the sludge, and forcing him to spit out Hitoshi. While Hitoshi brainwashes the Sludge Villain to prevent him from escaping, Mina voices her feelings on her own weakness even despite her fear, which is why she wants to be with people.

Hitoshi proceeds to brainwash and take command of Gigantomachia to attack the remaining threats, while Mina starts to pass out due to dehydration. Eijiro catches her, apologizing he's been a let down, and when she lets out that they are even, he responds that she never owed him a thing, because she's always been his hero.

With Machia under their control, and all the Villains defeated and restrained, Naomasa calls in to the Jaku Team for backup at the Gunga Mountains against the now rewinding All For One. Eijiro accompanies Hitoshi riding on Gigantomachia when they eventually reach All For One, with Machia commanded to throw a giant mountain right at him. Eijiro calls out to Fumikage, who is one of the Heroes chasing after him, telling him they are here to help ensure he doesn't reach Izuku and Tomura.

While Eijiro rides on Machia, All For One figures out that it was Hitoshi who was taking control of his behemoth and how they were able to get the Aoyamas to deceive him, commenting that it is his tactic. Deducing that Hitoshi was responsible, he attacks Machia with a giant blast to break his brainwashing and kill him, but Eijiro stands in the way using Red Riot Unbreakable to protect Hitoshi.

UNfortunately, the attack seemingly breaks the Brainwashing control away from him. However, Machia responds that even though he looks different, he can recognize his scent as his master, proceeding to ask why he left behind. Machia then yells that even after he came back in Tomura Shigaraki's body, despite having faith and waiting for him, he still abandoned him and ran away. Full of anger and rage, Machia turned against All For One for neglecting and abandoning him all these years and viciously attacks him.

Hitoshi notes how both Izuku and Machia are the only two to resist his Brainwashing, and how even with him under his control, he kept muttering about being betrayed. He declares that he is just along for the ride as a safety measure alongside his rage, adding that while a lot of people say his Quirk seems villainous, it has no control over a person's heart. With Machia now officially the Heroes side, the Heroes plus Machia throw their full assault on All For One until he vanishes for good.
