A/N: The start of the final war...

Just as Mikoto anticipated...

Aoyama Yuga was the key to luring out AFO. 

The "Demon King" foolishly thought he still have control over the boy...

But what he didn't expect was the boy to betray him.

Annoyed, All For One states that even if it was a setup, he is so close to him anyway, and since is able to track the positions and weaknesses of those it has been used on before!

AFO: The heroes would never make it in time. 

Using his Quirk, All For One summons an army of villains consisting of many prison escapees, The League Of Villains.

AFO: It is too late for you heroes!

However, All For One is once again taken aback when he spots Kurogiri's Warp Gate starting to appear behind them, he begins wondering how they activated him. 

While He thinks this saves him the trouble of getting him back, only to spot appearing from one of them. As the rest of the Heroes begin emerging from the gates.

Aoyama: AFO. I know the one thing you knows fears most! 

AFO:...And what is that?

Aoyama: Is that the world knows Japan isn't finished and if the heroes can lead the way! It will inspire the rest of them...so today is the day where you fall!

And like that, all the heroes appeared before AFO with determined enraged expressions.

The Final Battle Begins Now!!!

.... 

Jack: Whoa...How did he do that? 

Riku: It was revealed during the first era of Quirks, All For One stole a "Lie Detector" Quirk from one of Naomasa's ancestors.

Mikoto: So innorder to make sure Aoyama isn't lying. He commands the Aoyamas to deliver Izuku to him, using the Quirk to determine they aren't lying. 

Hein: So the key was Yuga seemingly supposed to betrays Izuku to All For One, only to reveal it was all an act they put on.

Kenji: That's a pretty smart plan. 

Tsume: But how was he not able to suspect the Aoyamas weren't lying?

Mikoto smiled at him. 

Mikoto: I got one answer for you. Brainwashing.

Tsume: Huh?

It didn't take long for the other students to realized what he meant.

Souta: Shinsou Hitoshi.

Mikoto: Yep. That's right!

Tsume: What? How?! I thought that guy could only brainwash people by response!

Hein: Hitoshi have trained his Quirk to the point that he can get people to speak now.

Riku: So they utilize Hitoshi's Brainwashing on the Aoyamas, to prevent All For One from detecting any lies in their voices, and having the brainwashed Yuga decide the specific meet-up point to lure All For One out.

Luna: OMG! That was so smart!!!

Zoe: *Nods* Mhm.

Mio: Whoo-hoo! Go Hitoshi-kun!

Maria: I really hope he joins our class...

Samuel: Sadly Big Brother believes he's going to join Class 1-A.

Luna: Awwwww....

Jack: Man...that sucks...

Eito: But can someone tell me why is AFO doing this?!

Riku: All For One's ultimate goal is to instill chaos throughout the world so that he may rise up using his arsenal of Quirks to take control of everything!

Sylvia: Then there's Niko who lives off of the chaos and corruption! They've been planning this for a while now!

Destiny: Guys! We got us a problem!

And just like that, the villains have swarmed everywhere on the battlefield! 

Mikoto looked at all his classmates. As much as they want too stick together. They have no choice but to split up and separate the villains. 

Haru:...

Mikoto: Haru...

Haru: ?!

Mikoto: We're going to make it out of this! Do your best!

Haru gave him a look of couragement. No more doubting yourself.

Haru: Right!

Mikoto: Class 1-C! You know what to do!

They didn't need to be told twice.

FIGHT THIS WAR AND LIVE TO SEE ANOTHER DAY!!!

The Heroes and charge toward each other, while All Might and the Counterforce observe from Central Hospital, Toshinori observed before stating just like they expected, AFO intends to end it all here so he can get. 

Shigaraki touches the ground, only to notice something peculiar, so he commands Dabi to attack. 

Shigaraki: Dabi. 

Dabi: Not now Bossman!

Dabi was already charging in full on attack to see Endeavor coming in at him as well.

Dabi: I didn't think you would be here for me to slaughter! Dear old Dad! Before we start! How about I cremate your face!

Before he could even try and burn Endeavor. A pillar of ice appeared stopping his attack. He grew annoyed knowing full well whom done it. But a psycho grin came on his face upon seeing the familiar red and white hair with scar on the other's boy face through the warp gate.

Dabi: Hahaha! Of course it would be you! HEY THERE SHOUTO!!!

Shouto: No way am I going to allow that! Not today brother!

Dabi: I hope you're ready to be burned with everyone else Shouto!

Shouto: I won't let you kill me, Nii-san. I will take you down!

Dabi: GO AHEAD AND TRY! YOUR FUNERAL!!!

Dabi taunts Shouto preparing to burn everyone with him, only for a large explosion of to appear and cancel it out.

As another frost prison surrounded him.

Dabi: (Hah...this wasn't Shouto's doing...)

Fumiko: My Goodness...My poor nephew...you really let yourself go...

Dabi glared at the woman while reminiscing at her. 

Dabi: Auntie Fumi...Is that you?! Ah whatever! Stay out of this or unless you want to get burned too!!!

Fumiko: *Sighs* As usual...you haven't changed much you when you was a child...like your father, you're incorrigible as ever. 

Dabi grew irritated at that comment but hhis anger but more or less directed at Shouto.

Shouto: Auntie...Leave him to me...

Fumiko looked like she wanted to protest but Shouto shook his head.

Shouto: I will save Nii-san...I will. Just help the other heroes take down any other villains. Block their paths from coming towards me.

Sensing that Shouto was leaving no room for argument. Fumiko just let out another sigh. She'll never understand men and their ways of always trying to act tough while taking everything on their own. 

Fumiko: You got it. Do your best. I believe in you.

Shouto: Thank you Auntie...

Dabi: Let's settle this! SHOUTO!!!!

With that, the two brothers attacked, fire against fire. 

Meanwhile, Emerging from another Warp Gate, the heroes, Class 1-A, Class 1-B, & Class 1-C join the battle, with Dabi and Shouto yelling at each other.

Shun: Are all the citizens far away from this place?!

Fatgum: I'm sure with the plan, they are! Right All Might?!

Toshinori nodded. With citizens far away thanks to Kurogiri's warp gates. They should be far away from danger.

All For One wonders if they plan on fighting in an all-out brawl, when All Might activates the Troy system.

Suddenly, cages emerge from beneath the battlefield, surrounding all the villains in individual metal containers. 

All For One knows they're aware they could break through them all easily, until he realizes what their plan is. 

All Might, Mizuki, and Naomasa all declared that even though they tried to bring him down once before...

Mizuki: All Might's stomach was destroyed, he's still alive.

Naomasa: We're still alive...

All Might: This time for sure they'll take him down. 

Neito: HAHAHAHAHAHA! Take this villain!

AFO: ?!!!

Neito Monoma summons several more Warp Gates around the cages, as the Heroes prepare to shove them all in order to split up the villains.

Niko: Kehehehe! We finally meet again, Mikochan!

Mikoto: Long time no see, asshole..

Niko: Awwww. Someone's not happy for see me~?

Mikoto: Why would anyone be happy to see an murderous entity?!

Niko: Such a shame...I was really hoping we spend some alone time together~! But sadly...it appears you're not alone. 

Three more figures appeared before Niko and Mikoto.

They were Sylvia, Yuiga, and Geysis. 

Yuiga pulled out his sword and gun while Geysis summoned Killer Doll.

Niko: Well aren't you familiar face~? Have you seen you before?

The question was directed at both Yuiga and Geysis as they sneered. 

Yuiga: I'm going to make you pay for what you've done to my classmates!

Niko: Oh right. The Original Class 1-C. Ya know...it was real fun breaking them down like the toy soldiers they are.

Yuiga growled at him.

Sylvia: *Angry* You did not just say that...

Niko: Oh. Did I strike a nerve?

Geysis: Niko Nikomatsu. The carnage you have caused for the past five years is inexcusable. We're bringing you to justice!

Niko: How cute. You've finally decided to act like a hero now? And you say...I'm finished here? Oh no no no...

Niko then powered up as a flash of darkness appeared around him.

Niko: *Demonic* I'M JUST GETTING STARTED!!!!
