Over with group A. They found the building the tracker signaled to, but they also noticed pro heroes and policemen already on the scene. Thinking that the battle was already over after one swift stomp from Mount Lady they start to leave. All except Akari who was left unmoved with fear in her eyes as they glowed a red color.
"Akari, are you ok," Izuku asked just as a loud boom went off.
Before anyone else even got to look, it was over in an instant. All the heroes and policemen were defeated in one moment. The building was decimated and the surrounding area was in ruins. Akari was the only one in the group to see the destruction as it happened. If she wasn't already watching she would also be like the others who couldn't move due to fear. She was used to seeing these kinds of sights, though hearing it happen and being able to feel it in front of her is another thing.
All For One stands beside Akumi at the center of the destruction, "Shall we begin?" All For One claps his hands. "That's the number four hero. Best Jeanist. I was planning to send them six feet under. But in an instance, you grabbed them by their clothes and threw them aside in the nick of time. Your judgment, technique, and reflexes are all praiseworthy."
"You're…" Best Jeanist pushes himself up with his quirk trying his best to put up any sort of a fight. He then suddenly gets hit with a sharp blast of air.
"The strength you possess is the result of your training and dedication to your power. But it's not something I need. Your quirk doesn't suit Tomura's needs." A sludge-like liquid forms and the League of Villain members appear out from them. "You failed again Tomura. But you mustn't get discouraged. All you need is to try again. That's why I've brought back your comrades. Sadly due to Akumi, I couldn't bring back the boy you deemed an important piece. So try again, that's what I'm here to help you do. It's all for you."
Group A hearing Akumi's name get spoken, broke out of their fear for a moment enough to move as Ida stopped Izuku and Todoroki while Yaoyorozu held onto Kirishima. Akari on the other hand was in disbelief. Nothing was making any sense as to what happened to Akumi. Such a short amount of time had passed for there to be no traces left of her original colors.
All Might then comes flying in from on high with All For One catching his punch. "I'M GOING TO MAKE YOU GIVE EVERYTHING BACK ALL FOR ONE!"
"Here to kill me again, All Might!?" The ground shattered from the impact. "What took you so long?" A shockwave sends the league members away while Akumi stands completely still.
All Might get pushed back, noticing Akumi expressionless he asks, "WHAT HAVE YOU DONE TO AKUMI?"
"It's about five kilometers from the bar to here. And it took you a whole thirty seconds to arrive after I sent the Nomu. You're losing it, All Might."
"ANSWER THE QUESTION!" All Might lunge at All For One winding up a punch.
"So very impatient." All For One activates his quirk in one arm then aims a blast at All Might sending him crashing through multiple buildings. "In any case, get out of here Tomura. Kurogiri will help with your escape," All For One sends mechanical tendrils from his fingers and force activates the unconscious Kurogiri's quirk opening a warp gate. "Now go."
"And you master?" Shigaraki asked.
All Might come back and again goes to punch All For One, "YOU WON'T GET AWAY!"
All For One grabs the unresponsive Akumi, placing her between him and All Might. This caused All Might to halt his punch for a moment and get blasted away again, but this time All Might was expecting a blast and wasn't pushed back as far as before.
Akumi's eyes flicker to life. In an unfamiliar location, she can feel that her master was there. She looked around seeing the destruction. The grasp from her neck felt warm and comforting. "Tomura, don't worry everything will be fine," she says.
"Putting in a quirk seems to have given it some personality," All For One says as he lets go of Akumi. "Why not give a good scare? Do it for your old friends."
The comforting feeling disappeared as she tilted her head at a wall, "Old friends?"
"We need to leave," Akari whispered.
"What? Why?" Izuku whispered back.
In a flash, the wall Akari, Kirishima, Izuku, Ida, Todoroki, and Yaoyorozu were hiding behind broke down. Akumi pinned down Yaoyorozu and Kirishima by the neck. All Might see this and tries to intervene but is interrupted by All For One. Akumi then flings Yaoyorozu and Kirishima's bodies toward All Might and quickly walks back to stand next to All For One. "Sorry master, they weren't old friends."
"What's her deal? Wasn't she just supposed to be a mindless Nomu? Why does she act like this all of a sudden."
All Might catch Yaoyorozu and Kirishima, "WHAT ARE YOU KIDS DOING HERE?"
"W-we can explain…" Yaoyorozu says before being interrupted.
"YOU CAN TELL ME LATER FOR NOW GET OUT OF HERE AND TO SAFETY." All Might lets down the two.
"Akari what's happened to Akumi why is she acting like that!?" Izuku asked.
"That's not her…" Akari says, her voice shaking. Connecting the reason why her colors were so different was that this wasn't Akumi. There was no trace of her quirk when she moved.
"What?"
"I said THAT'S NOT HER! We need to leave!" Akari grabs Izuku's hand and starts to run. "We'll only get in the way of All Might and the pros."
"Wait," Izuku stood his ground.
All For One begins to laugh maniacally, "No one here beside me, and that girl knows what's going on. This right here is a new and improved Nomu." All For One places a hand on Akumi's head. "This is a clone created from the original Akumi. It was quite rushed but as you can see she'll listen to whatever I say without question. I call this model Seo."
All For One then extended his mechanical-like tendrils out towards Magne to his surprise digging into him and force-activating his quirk, "W-why are you attacking me!" The male league members magnetized to Toga who was standing next to an open warp gate.
"Why Master? We can help!" Shigaraki shouts while trying to resist the magnetic pull.
"No this is not your time yet. Escape, grow stronger. Everything will be yours soon."
All Might go to intercept their escape but Seo interrupts by throwing her body into All Might. This gave enough time for The League of Villains to all magnetize through the closing portal. All For One and Seo were the only ones left as Edshot, Endeavor, Gran Torino, Kamui Woods, and Tiger arrived. All Might's time limit is nearing as steam starts to emit from him as he restrains Seo in his arms. Group A was forced to evacuate by Kamui Woods and Tiger.
"All Might let us handle her. You're running out of time. Focus on the threat," Gran Torino shouts, kicking Seo in the head trying to knock her out but to no effect.
All For One raises a hand compressing air saying, "Seo. Give an opening. A big one if you can."
The brightest smile was on her face. Seo starts pushing All Might's arms away and winning the contest of strength. "Yes, I will master."
"ALL RIGHT. I'LL LEAVE HER TO YOU." All Might lets go of Seo as she flies up. All Might again blitz All For One. Endeavor and Gran Torino chase after Seo.
"Are you sure you should be concerned with me right now? You're almost at your limit." All For One unleashes a wide blast which All Might dodge.
"I'LL TAKE YOU DOWN, LONG BEFORE THEN!" All Might land a punch on All For One's helmet breaking the top half and revealing his disfigured face with flesh where the eyes should be. All For One is knocked to the ground as All Might stands over him.
"Want to know a little secret, All Might? Your successor Izuku Midoriya will never be able to bring back his beloved sister." This comment shocked All Might with just enough time for All For One to shoot All Might, sending All Might up and colliding into Seo. Endeavor and Gran Torino are trying to reach her but she just goes higher and higher.
"The perfect opening," Seo said, latching onto All Might and self-destructing. A huge explosion goes off in the sky illuminating the destroyed city blocks for miles. The news helicopter recording the footage gets blown down from the sky with its connection turning off. Endeavor rushes to save the civilian in the now crashing helicopter.
All Might was heavily damaged by the blast but is still conscious. Gran Torino catches him and lands back down. "This is do or die Toshi. Your form is about to fall apart. You have one shot left, give or take."
"Just as much as you hate me All Might. I hate you just as much. While I did kill Nana Shimura. You took something away from me too. That's why I want you to have as gruesome a death as possible." All For One begins to charge up another compressed shot in his arm.
"It's coming again. Dodge and then counterattack!" Gran Torino says jetting away.
"Are you sure you want to dodge this?"
All Might notice an unconscious Ragdoll amongst the rubble behind him so he stands there taking the full force of the blast. "Though my body may rot away and decline. My spirit remains. I am still the symbol of peace. And you can do nothing to take that away from me!" All Might was now completely deflated with a bloody fist raised. A glow from his eyes and a smile on his face as his determination flared out.
"I had forgotten how stubborn you were. In that case, I'll let you privy to another secret. Let's see if your spirit can still hold up. Not only is your successor's sister a Nomu I created but Tomura Shigaraki is Nana Shimura's grandson. I created the opportunity for you and Tomura to meet. And you beat him to submission, didn't you? Without knowing a thing."
"You… You're lying!" All Might was left speechless. His smile slowly turned upside down.
"But it's the truth. Not only that but you didn't even notice the Nomu called Akumi I planted from the beginning manipulating Izuku Midoriya to be your successor." All Might's smile was gone and with it his resolve. "That's weird All Might. Where'd that smile go?"
"You… You scum!"
"I'd say I got more than a fragment of your spirit there. So how does it feel giving your quirk to someone I chose for you?"
All Might scream not knowing what else to do. Has he made such a blunder in giving hope to Izuku? Attacking His master's grandson? Or is it protecting Akumi the Nomu? Though he does not know whether or not he was in the right, he knows one thing for sure, "YOU'RE RIGHT ALL FOR ONE." One of All Might's arms bulks up. "BUT EVEN SO, I TRUST THAT MY ACTIONS THAT HAVE BROUGHT ME THIS FAR ARE NOT WRONG! I SHOULD INSTEAD BE GRATEFUL FOR YOU TO SINGLE-HANDEDLY HAND ME THE BEST CANDIDATE TO INHERIT MY POWER."
All For One begins to float up, "Wounded heroes are the most dangerous of all. But I know for sure this time you'll die here."
"Explain that pathetic state you are in All Might!" Endeavor shouts arriving back after saving the civilian.
"If you're just here to cheer him on then act like a real audience and sit down and behave." All For One points his arm at Endeavor.
"Not so fast you savage. We came to help!" Edgeshot interrupts All For One's compression with a quick hit on the head. Endeavor then shoots his flames at All For One.
"Oh please… None of your futile attacks will even matter in this fight." A huge shock wave knocks back the two heroes. "Springlike limbs, locomotive corkscrew, explosiveness, four kinetic boosters, three strength enhancers, a multiplayer, hypertrophy, rivets, air walk, spear-like bones. Up until now were just meant to wear you down. Nothing lethal. To kill you my current accumulation of quirk would stand no chance. That is if I didn't know what you were going to do next."
One of All For One's arms bulks up. Extra arms, spear-like bones, and gem-like structures protrude out of the arm. Lunging towards All Might, All For One says, "Izuku Midoriya! He came to you completely unqualified… You've got plenty to regret as you die All Might. Because I would have not taken one of his heroes but his number one as well."
Their bulked-up fist collides, and the power in All Might's punch gets recoiled back to him due to one of All For One's quirk. As All Might begins to lose ground he says, "That's right, as a teacher I've definitely fallen short. As my successor's number two, I'm willing to accept that!"
"Pathetic," said All For One. All Might then transferred his power from his hand to the other letting the arm that had collided with All For One break. All For One had already seen this played out and easily dodged the attack. "Farewell, All Might!" All For One's other arm was already prepared and he hits All Might with full force slamming him to the ground before All Might could do anything about it. A huge tornado appears for a moment. A crater made by the impact of the attack. All Might, on the ground the light slowly fading from his eyes. "United States of Smash. That was the move you were going to use to finish me off. I would have loved to keep you alive, but the future is beginning to change, All Might. Change in my favor, all thanks to Akumi."
A girl's voice screamed out in All Might's head, "You can't let it end like this?!" All Might's breath started to slow. His heartbeat grew weaker.
"Toshi you have some unfinished business." A woman's voice said calmly. Hearing the familiar voice gave All Might's remaining blood the strength to circulate one last time.
"Eighth you can't die just yet. To set things back on course you need to take him down," a man said confidently. All Might, at the brink of death, take in one last breath of air.
Faster than he has ever been before, All Might bulk up to his muscle form. All For One was in shock he was sure he had finished All Might off. All Might get in a stance ready with his fist for the last attack. The smile on All Might's face was even brighter than the glow from his eyes. All For One sensing the dangerous situation wasn't just going to take the punch. "UNITED!" All Might shouted, winding up his punch.
"Do you think I'm just—" All For One noticed he couldn't move his arms or legs. "This is…"
"STATES OF!"
All For One notices Yumi's quirk resonating with the remaining embers of One For All, "Damn it! How are you able to interact with that quirk!"
"SMASH!" All Might slammed his fist down onto All For One's face pile driving him straight into the cemented floor. All For One is unable to move due to Yumi's interference and takes the full force of the attack. Shockwaves like those from a large explosion can be felt miles away. An even larger tornado formed, clearing the surrounding area of rubble and creating a much larger crater. If there were clouds in the night sky, there wouldn't be any now.
Both All Might and All For One's vision goes black. "You Ungrateful, Little, Brat!" All Might's vision comes too to see All For One chocking out Yumi. "And now he's here. Hello, All Might. How nice of you to drop in," All For One said, dropping Yumi to the floor. Yumi falls on her back coughing and gasping for air.
"Akumi!" All Might, now in his skinny form, tried to approach but was stopped by a muscular woman. "Who…" To his disbelief, it was his mentor and friend Nana Shimura.
"It's been a while Toshinori," the woman said with a smile.
"But how—"
"Now is not the time," Nana said as she turned their attention to All For One and Yumi. "You're dying All Might."
"Yes yes, we are dying All Might," said All For One. "All because of her. To think what did us in was this little girl's actions."
"Akumi how…" All Might got a closer look at the girl and notices she is not Akumi but nonetheless, he is All Might and he will save her. "You're not Akumi are you."
"Yes, correct, how did you know?" All For One mocked. Yumi slowly crawled away after regaining her breath. "We would both be alive if you hadn't stopped my movement." All For One slowly approached the cowering Yumi.
"Stop Right There All For One!" All Might gather whatever's left smoldering of the One For All quirk to get back into his muscular form. "I Will Not Let You Harm That Girl. Even In Death, I Will Not Allow You To Bring Harm To Anyone Ever Again!"
"It Doesn't Even Matter. We'll Be Dead Anyway!" All For One cackle.
"She will be the turning point in the upcoming battle against All For One." Nana was now gone and in her place was a man with white hair. "Eighth there is only one way to save her."
"What but isn't he…" All Might paused and remembered Tomora Shigaraki, or should he say. "Tenko Shimura. He gave his quirk to Tenko Shimura."
"That's exactly why that girl over there was even able to resonate with One For All. If he still had the original quirk she wouldn't even be able to connect with us at all. Which is exactly how we can save her."
"How do we do that?"
"We do not have much time but if we can–" The man disappeared in a cloud of mist.
All Might can feel the power in him quickly disappearing. Without hearing what the man said he goes off of instinct and what a hero does best. That is to save those in need of saving in front of them. All Might lunge at All For One and All For One catches the punch that All Might threw.
"In here we are equal." He threw All Might away with one hand. "What's even the point anymore? You got what you wanted. You stopped me. I'm dying. I can't hurt anyone anymore."
"It's because she is my successor's sister. I'll need to bring her back before I can rest easy. But more than that, I can't let it end like this." A smile on All Might's face as a white light began to envelop the area.
Outside, Grand Torino is holding in tears at the sight of seeing All Might. Endeavor and Edgeshot solemnly look over the body of All Might. What they see is All For One's dead body on the ground and All Might in his skinny form lifeless, but standing straight with a smile on his face and his left arm up to the sky as if he is holding on to something.
