The clash between the two threw everyone away. Despite this Bakugo remained surrounded, as he regained his footing, the villains surrounded him. Desperate to grab him, and leave the area. The students, equally as Desperate, could do nothing but watch.

A strike from Toga dodged, a swipe from Shigaraki dodged as well. The students watched on as Bakugo narrowly missed another strick.

Mirai turned her focus to All Might, who was being kept occupied by All for One. Throwing All Might back, All for One hesitated for a short moment. At that moment, All Might lunged towards him, before being thrown back, without All for One moving even an inch.

How fast did they… wait, somethings off about this.

"Todoroki! I have an Idea!" Midoriya quickly whispered the plan to Todoroki and got In the position to execute It. Launching forward, breaking through the wall, the plan went Into motion. A massive wall of Ice, formed beneath their feet.

The Villians looked on In utter shock at the new development. The small group launched off the Peak of the Ice, Kirishima quickly called out to Bakugo. He wasted no time, launching himself towards them with a massive explosion that threw Shigaraki back.

The villains tried to launch themselves In pursuit but failed. All for One then opened a portal, ushering them Into retreat.

"Time for us to leave," Yaoyorozu said looking expectantly at Mirai. Mirai was watching with All Might with a confused look. "Mirai?" Yaoyorozu nudged Mirai, getting her attention.

"I'll be right behind you," Mirai said with her brow furrowed. Yaoyorozu hesitated before she began to leave. Mirai watched the fight between the Two strongest In the world.

I don't like this feeling I'm getting. Mirai thought as All Might moved his arms to block a blast of air. At the same moment, he lost his footing, forcing him to catch himself. The blast struck him, and he was thrown back.

No… That's Impossible… Mirai thought as she pieced It together. Why can't I see them though? Mirai rubbed her eyes hastily and looked again. She still couldn't.

All Might once again was struck by an unknown force, and then hit by a follow-up attack from All for One. I need to focus, or he'll lose! Mirai closed her eyes, focusing herself. I may not have had to look for them for a while, but I should still be able to see them.

After what felt like an eternity to Mirai, she opened her eyes again… At the same moment, All Might was knocked back by the same entity who had hit him before. The Youmu was a bulky one. It looked like a sphere and just floated In the air. When It attacked all Might a black substance, the same as the Youmu's color, struck him.

"Haah!" Springing from the cover of the wall, Mirai thrust her sword Into the Youmu. The Youmu seemingly staggered forward. Mirai quickly pulled her sword out and blunted It.

The youmu swung Its almost pitch black Tenderal towards Mirai, She lunged away, before swinging with all her strength, launching the Youmu Into nearby buildings.

"Y-Young Mirai?!" All Might stared In surprise at her appearance. Mirai sharpened her blade as she turned her gaze towards All Might.

"Oh? She can see them as well." The raspy, sickening voice of All for One rang out, All Might Immediately snapped back to attention.

"I'll draw Its attention, you focus on All for One!" Mirai shouted towards the Symbol of Piece, as the Youmu appeared from the rubble. All Might nodded In response.

All for One began to laugh as he faced off against All Might.

The Youmu shot forward, Mirai quickly readied herself. Meeting the Youmu's strike with her own, she parried It away and cut off the Tendril. Quickly moving her arm, she stabbed into the sphere.

With a pop, the youmu was reduced to just a mere ore. Mirai caught her breath and picked up the ore. Stashing it away she turned to assess All Might's situation.

All Might suddenly shot forward, His fist flinging forth with Incredible speed. All for One attempted to dodge but was too slow. All Might slammed Into his head with all his strength, then smashing the seemingly limp body of All for One onto the ground.

All Might caught his breath, Mirai didn't know If it was the punch or something else, but what seemed like steam began to emit from All Might's body. A low murmur emitted from All for One, causing All Might to tense up.

"What's wrong?" All Might's mouth was agape, his fist still embedded Into All for One's now broken helmet.

Mirai sighed and prepared to enter the main battle, suddenly Mirai was thrown away. Using her sword to slow herself down, Mirai gazed at the entity who Interfered.

It was a second Youmu. This time it seemed to be a blackish fog, Mirai could barely make out what seemed to be a small black triangle In the center of the youmu. The Youmu took the form of a human and began to approach her.

As the second youmu approached her, Mirai saw a third in her periphery. "How unpleasant, how many more of these are there!" Mirai said as she split her blade Into two, forming to Kunai.

The third youmu took a place side by side with the second. This one seemed to be a mix of a fox and raccoon. In an Instant, the third opened Its mouth, lighting poured out of it and towards Mirai.

Mirai slashed a nearby metal beam, and stuck It into the ground, using the makeshift lighting rod to charge the second. She quickly got Into range and swung both Kunia towards the triangle.

Before she could see if she connected, a massive blast of air erupted from where All Might once stood. Knocking Mirai and both Youmu away, Mirai quickly threw both kunai at the Youmu.

As both were reduced to Ore, Mirai struggled to her feet. Grabbing the two pieces of Ore, she turned her attention once more to the fight with All for One. "All Might…" Mirai stood watching a bruised and bleeding All Might, he lacked his muscle he had before.

Gran Torino crouched next to him, ridiculing him. All Might coughed and replied, "Yes, sir…" Mirai then turned her attention to All for One. the villain staggered to his feet, his tuxedo ripped In many places, and his mask broken.

As Mirai watched All for One Warily, Gran Torino continued his talk with All Might. "Go beyond your limit, Its do or die time!" All Might gave a simple reply, his determination to win restored.

"Yes sir!"

…

Midoriya stood watching the screen. "No, no! All Might can win!" Midoriya was becoming Increasingly worried. The camera then turned to another person, who was fighting a seemingly Invisible threat.

"Mirai!" Midoriya shouted as the camera caught her dodging an Invisible strike.

"What is she…?" Midoriya could do nothing but watch.

…

Mirai cut down the fourth Youmu, caught her breath as All for One finished his monologue. His arm suddenly burst out, with black and red lighting emitting from it.

"This will be a big one, Dodge It and counter-attack!" Gran Torino hurridly yelled as he launched himself Into the sky. All Might got into a position to do the same.

"Are you sure you can dodge this one?" All for One said In an utterly sadistic tone, aiming directly for All Might. All Might turned In horror and saw a woman unconscious behind him.

He quickly switched position and got ready to defend against the blast. All for One unleashed It, and All Might winced In preparation for the pain.

But It didn't come.

Mirai stood Infront of All Might, struggling to hold the blast back with her shield made of blood. "Mirai, what are you…?" All Might said as Mirai grunted from the effort, her arms covered In scratches and cuts from the blasts Impact. The sleeves of her cardigan torn.

"All Might, you can't die here, Midoriya needs you!" Mirai fell to one knee as the blast ended. She caught her breath as All for One clicked his teeth. "Interesting, your stong enough to block that."

"You won't block the next one, Mirai! Run!" All Might pleaded with Mirai, who formed the shied again. "All Might, here's your chance to end this nightmare. Gran Torino!" Mirai yelled to the retired hero.

"What are you doing here kid!" Gran Torino landed behind her. "Gran Torino, get as many civilians out as you can. Al Might, take care of him." She continued as she pointed at All for One. "I'll by use as much time as I can."

Gran Torino reluctantly sped away. While All Might gathered as much energy as he could. Mirai dropped blood onto the ground.

"Are you sure about this?" All Might asked as All for One's are began to grow and spark.

"I am," Mirai said as All for One glared at her. "I've had enough of you." All for One's arm suddenly burst out of the tuxedo's sleeve. Mirai made her shield as dense as possible.

I guessed wrong Mirai thought, as All for One's arm became enlarged with what seemed like spikes growing out of it. "I was going to save this for All Might, but It seems It's necessary for you." All for One said as he launched himself towards Mirai.

His Arm collided with Mirai's shield. This impact Itself nearly caused Mirai to throw up, Her legs shook from the Impact. Her entire body creaked from the effort of holding his fist back.

With a smile, she threw her free arm up. All for One winced as blood spikes erupted from the ground. "Clever." All for One commented as his other arm began to spark.

Shit. Mirai thought as he threw his palm towards her. Mirai lunged back as far as she could, and made her blood wash over her entire body, as All for One blew her back with a blast of Air.

"Mirai!" All Might shouted as she flew Into a nearby building.

Moving the blood back into her body, Mirai struggled to her feet. "Oh, your quite durable." All for One said with disdain.

All Might shot forward, but All for One met him with his grotesque morphed arm. All Might was pushed back, yellow sparks emitted from his one arm which still maintained Its previous muscle.

As All Might got footing, a massive gust of Air threw Mirai back. Mirai got too her feet once more and formed her sword. She launched herself towards the two titans.

She struck down, a fifth youmu, who attempted to Interfere. She then slid under a blast of Air from All for One's free hand and stabbed at his leg. With a clang, her sword didn't even pierce the skin.

"I heard how you defeated Eraser Head, and figured I should take precautions" All for One then threw All Might back, and swung towards Mirai.

Without time to react, his fist slammed Into her stomach, throwing her away. Mirai threw up from Its impact, as she was launched into a building.

…

Midoriya covered his mouth with his hand. Whats Mirai doing?! Midoriya thought as the camera switched between focusing on Mirai and All Might.

…

Mirai cut down the sixth and seventh Youmu and clutched her stomach. Wincing as she recovered from the strike.

As she struggled to recover, a blast of flame shot towards All for One who blocked It without issue.

Turning her gaze, she caught sight of a group of Heroes. They all looked very beat up but joined the battle nonetheless.

"What's with that Pathetic form All Might!" Endeavor, the number two hero, yelled at the weakened All Might.

"We barely made It in time, we were held up by something." Another hero said as All for One turned his attention to the new arrivals.

"If you came to cheer him on, be quiet like a good audience!" All for One said as he let a blast loose at the heroes.

Dodging the blast, they began to engage the villain. One hero grabbed the unconscious heroes, while the other two stalled All for One.

Mirai ran forwards and swung at All for One with all her strength. His arm buckled for a moment, but before he could retaliate, Mirai leaped away Endeavors flames covering her retreat.

Edgeshot launched kicks at the villain, All for One dodged, and then blew the approaching flames away. Mirai called out to endeavor.

"Throw me at him!" Endeavor quickly obliged, and threw Mirai towards All for One.

Mirai spun through the air like a disc and struck All for One In his Arm, his spikes tearing through her sword, and soaking the ground In blood. "It'll take more than that!" All for One quickly threw her back.

With a pained smirk, Mirai threw her arm up once more, and spikes sharper then the last time shot up from the bloodied ground. Endeavor shot more flames towards him, while Edgeshot threw another kick, pinning the villain.

"Gah!" All for One grunted In pain, as the spikes drew blood. "Enough of this!" All for One then shot a blast Into the ground.

The blast knocked everyone away, Mirai landed onto her arm, breaking It. Getting up, she clutched her arm. Endeavor stood next to her, getting up as well.

"We can't do anymore, let's withdraw." He looked expectantly at Mirai, who nodded In agreement. The Heroes withdrew from the area.

"Well, lets finally end this, All Might!" All for One yelled as he launched himself towards All Might.

"Yes! This is the end All for One!" All Might reared up a punch.

As their fists collided, All Might's arm gave way, narrowly avoiding the punch All Might's other arm bulked up.

His fist slammed Into All for One's head.

"Someone's been Influencing you! It's Weak!" All for One threw his arm back as It sparked. All Might's bulked up arm then reduced to what seemed like just his bones.

"That's because my back wasn't In It!" All Might said as he began to rear up his other broken, bruised Arm. His hand seemingly grabbed something, as It bulked up In an Instant.

All for One quickly shot a blast towards All Might with his free arm, but he ducked Under it. He then quickly threw his fist with all his remaining strength.

"United… States of…" His fist connected with All for One's cheek, knocking him off his feet, as All Might continued.

"SMASH!" All Might screamed as he slammed the Villian down, creating a whirlwind that knocked Gran Torino and the nearby helicopter away. The whirlwind ripped up nearby buildings, which were then thrown threw the air.

All Might stood up, the world seemingly silent. He then bulked up and took his signature victory pose.

…

As All Might gave his victory pose, a voice emitted from the ruins.

"It seems my support didn't help as much as I thought It would. I did learn something interesting, though."

The person the voice belonged to then left the Area.

…

A few hours later…

Aizawa as well as the principal and the heroes that taught at UA called Mirai to the school. The fact that she became involved In the fight was troubling.

Mirai entered the room. The teachers watching her as she took a seat.

"I have a feeling I know what this is about," Mirai said as she settled Into her seat.

Aizawa nodded, "Don't worry, we've explained your situation to the teachers here. Mirai nodded and addressed the room.

"It seems that creatures from my world are appearing In this one," Mirai said as the teachers looked on.

"What proof do you have?" Present mic asked, at that point, Mirai placed a handful of Ores on the table.

"In my world, when people like me take down a youmu, they become ore. I took down around seven or eight." the teachers looked worried, Mirai continued nonetheless "The concerning thing is… I don't have any idea how they are coming Into this world. What's even more worrisome, is the fact that All for One could see them."

The room's atmosphere became heavy.

"Alright. I leave this matter too you to Investigate, Inform us of any new developments. Make sure to keep It discrete. Until then, stay safe. If you encounter any of these creatures that you believe pose a threat, feel free to take them out." Aizawa said, before dismissing Mirai from the meeting.
