Chapter 9 – Hero

"So, before I continue, let me explain the Mutation quirk more in depth."

Izuku's dad said, giving him a serious look.

"… Dad, it may be too late to ask this, but… Aren't we short of time?"

"Don't worry son, time here is different from there. I feel like I've been here for months, but in reality, I'm here for 15 years."

"Oh… Seems legit."

So Hisashi and Izuku were sitting on the chairs, while they were talking.

"Izuku. You have Multiple-Quirk Holding. That is a short name for both of the quirks you have. I know, it's not creative."

Hisashi was now trying to explain Izuku's power, aiming to be as brief as possible. Even though they have a lot of time, it is not infinite.

Mutation is a special quirk, that only the Midoriyas have. There's not even one similar quirk to it in the world.

Basically what Mutation does is to change the quirks the owner possesses, like changing the draw-back, or even the strength of said quirk. Luckily, Izuku had inherited One for All, so he could change it.

To his, and even Hisashi's surprise, Izuku's second quirk is Determination (I know, the name is SOO META), and it enhances Izuku's physical power, hand-eye coordination and other things according to his mood, or how it's better to be called determination. It cannot be downgraded though. It's a win-win quirk, no down sights.

So that combination plus One for All made him superpowered, but he doesn't know how to use that. He will have to do it at the time, for he couldn't test his Quirk in his own mind.

"… So that's all, son."

"… Wow…"

Deku was dumbfounded. He would never think, not even in 100 years, that he had those quirks, that explained a lot of moments in his life, including why he didn't feel any difference while being bullied, but feeling extra insight when doing things he liked. His quirk consisted on an emotional rollercoaster. The quirk is the person that rides the roller coaster, sometimes it is high, others low.

"… Ok, son. I guess now it is time for us to say goodbye, unfortunately… I-I really w-wanted to s-spend more time w-with you, d-dear…"

"… Y-yeah…"

After that, both of them hugged for some minutes. Both of them loved each other, one being a father that couldn't be there for his son, while the other is a son that was heavily bullied, wanting a father figure in his life.

All Might is a father figure, but nothing can replace a real father. That inexplicable bond between both of them: Son and Dad.

After that, Izuku's dad wanted to tease Izuku. I mean, half-tease his son.

"Izuku."

Said Hisashi with a half-serious half-joke face.

"Yeah?"

Izuku was now a little bit confused but nodded.

"You know that girl… Uraraka, was it?"

"Y-Yeah?"

"… Go get her. I ship it."

Izuku's head exploded in a crimson-red blush, expelling smoke through his ears, and nose.

"W-w-what was t-that, d-dad?"

Hisashi then chuckled.

'I know you ship it too, reader. Being inside Izuku's conscience allowed me to experience some things that made me understand: We're in a crappy fanfiction in some world. Yeah. Privacy invasion is a crime, you know?' – Hisashi thought to himself while looking directly above himself, where your POV is. Scary…

"Ok. Without further ado, you have to… go…"

The last part was said with a sad tone, almost a whisper. Izuku heard it though.

"… Dad, I'll miss you very, very much. I love you."

Izuku said so with his eyes almost tearing up, for like, the third time.

"I love you too, Deku – The hero that can do it, my dear son. I'm very proud of you."

Hisashi said with a gentle smile, that formed on his face. After that, his face now resembled a student that forgot to study for finals.

"OH! Izuku. When you get home safely, tell her that I love her. Protect her, son."

"Sure, dad!"

Right after that, Izuku's view got completely white. He was starting to smell the grass, and other scents mixed in, and he was coming to his senses. His view was now filled with gray, as the ceiling of the dome was there. He remembered: 'I need to save them! I need to be a hero!'

Shigaraki was right there, beside him. He was standing while looking at his classmates, which were crying. Bakugo had a worried look, as he had matured enough not to be 'Bakugo' on this situation.

Izuku had not yet moved, as he was planning. He formed one very quickly.

Deku remembered the explanation from his dad, now he had to activate his quirk. He was going to try it while on the ground, as according to his intuition, he didn't need to be standing.

But, Shigaraki was now approaching Uraraka, the curly haired girl that Hisashi joked about, also Izuku's secret crush.

Midoriya looked at that, and now his heart started to ache. He had to save her. Suddenly, something grew on him, and Izuku was filled with determination, his eyes started to glow green, that glow being strong. He was wearing a serious expression.

Izuku stood up in an instant, calling the attention of the class. The ground where his feet were standing was now being crushed, forming small craters below his feet.

The class, the villains, and everyone near him were feeling pressure. Something that surpassed Stain's aura. About that, only Todoroki and Iida made that comparison.

Everyone was standing still.

Izuku then moved at a speed so fast, that it looked like a teleport, only leaving a trail of neon sky-blue in the shape of lightning.

Shigaraki instantly bade a barrier around him and Izuku, isolating them both, while the rest was outside.

Izuku punched Shigaraki's back, making him fly to the end of the barrier. The wind-pressure made even those that were outside retreating a bit, while the students were thrown a little bit back. Little did they knew that said barrier blocked the wind pressure, leaving only the aftershock of the said pressure. In short, it was a crap-ton of power.

The barrier broke, and Deku grabbed Shigaraki by the neck while jumping and spinning on the air. Right after 2 spins, he threw Shigaraki to the ceiling, exploding said ceiling, only to reveal the blue sky with the sun shining above it. In the sky, was a helicopter, which was recording all the ruckus that was happening outside. The reporters were surprised by the explosion, but they recorded it nevertheless.

Shigaraki reached the helicopters, as they pointed their cameras at him.

At that time, on his face grew an evil grin.

"… YOU SHOULDN'T HAVE RESPAWNED, DAAAAMNIT!"

Shigaraki was enraged. Deku was supposed to be dead, while he was supposed to tear every student's mood apart and make even some cry.

Shigaraki was descending quickly at Deku, while said boy jumped at Tomura, leaving a huge crater below him, and sending debris around him. Luckily, the villains destroyed the debris, for their own sake and that saved the students of 1-A. Izuku had no idea of his own strength.

Tomura grabbed Izuku's arm, spun around a couple of times, and threw him on the ground where his crater was, and putting weight onto his hands using one of his quirks, he fell 5x faster at Deku.

He pounded the ground, Izuku wasn't there. A huge screen of smoke formed, and a huge explosion sound was heard.

Izuku was behind him. He activated Full Cowl, that was now 100%, and kicked the back of Tomura's knees, making him fall onto said knees. After that, Izuku stepped to Shigaraki's left, and using his hand, pounded him into the ground. Shigaraki was there, but almost unscathed.

Suddenly he disappeared and was behind Izuku. He tried to punch him, but Izuku blocked it, sending the shockwave to the diagonal down to left.

Blackmist then realized that, if they battled here, they would be dead. That's only by what he felt from the wind-pressure. Then he created a portal below Izuku and Tomura, teleporting them to the Ruins Zone.

They didn't feel like it was dangerous. Tomura knew it was Blackmist and was thinking the same thing, while Deku's intuition told him so.

The helicopter quickly found them, as they heard loud explosions and strong wind currents from there. Right now, the battle was live at the news.

The pros from U.A's quirk were taken by Shigaraki and were now powerless watching the fight from afar. Luckily Toga was also interested on the fight, and let them watch it through one of her stolen quirks. That quirk allowed her to project an image from what she is seeing. She was streaming the News channel from her phone.

Izuku and Shigaraki were at the center of the Ruins Zone. Buildings around the both of them.

They started to exchange blows, exploding all the nearby buildings. This was a colossal-scale battle.

At some point, Shigaraki successfully landed a blow into Izuku's guts, sending him to the nearest not-destroyed building, now it was destroyed.

Izuku was in a tired state, worn-out and weak.

While Shigaraki was approaching him, slowly to provoke psychological fear, which wasn't working, the One for All's previous holders appeared beside's Deku.

"Are you going to give up, Izuku?"

"…"

"Giving up, kid?"

"…"

"What about them? Don't you want to save them?"

"…"

Izuku was feeling like staying on the ground. His body had small parts of decay, that was blocked by his cells. They could make an antidote capable of slowing the process, after getting used to it.

He was worn out both physically, and mentally.

"Izuku… You're not like this. What about your dream? Don't you care about it? Don't you care about them?"

"… I-"

"Don't give us that crap! All Might chose you for a reason. Don't back down now! You're the only one capable of doing this!"

Izuku's eyes were now neon-green again. He was filled with determination.

Inside his body, Determination changed his One for All, it was now rising more. Also, he removed the drawback of One for All, now he could use-up more of his power. He wasn't aware of that.

For Shigaraki's surprise, suddenly behind him was a green-haired boy, worn-out and looking weak, but he was giving that pressure, that now made even the reporters falter.

He barraged Shigaraki, who was trying to block, but only did it to 60% of his blows. He was substantially stronger.

He grabbed Shigaraki by his neck, jumped leaving a crater below him, and barraged him again, in mid-air.

Shigaraki was now filled with rage, his eyes glowing red.

He then grabbed Izuku and pounded him onto the ground. Shigaraki was now even more powerful.

While Izuku's back was facing the ground, Shigaraki started to barrage him, with an unimaginable speed, making him spit out blood.

Izuku was on the verge of unconsciousness.

'Deku… It sounds like you can do it!'

'You can become a hero...'

'Thanks, Midoriya.'

And a bunch of other good memories started to fill Deku's mind. He was remembering all the good times that he and his friends went through. All Might's words that changed his life forever, Todoroki's words at the tournament… And Uraraka, with the sentence that made Deku accept his name.

Midoriya was happy. He had friends…

He didn't want to lose them!

'Don't give up!' – He could feel that his dad was screaming that inside his mind. He then remembered his mother, and what he promised to his dad.

"I WON'T GIVE UP!"

Deku's voice reverberated through the entire USJ, reaching the reporters and streaming it through the News.

Everyone that was watching was filled with a safe feeling. They felt like they could believe him. The boy. They didn't even know his name, but they felt a connection with him. Their hero.

The 1-A also heard that and were smiling. It was their friend, the hero, Deku.

Uraraka's stomach was having butterflies while being happy.

'I… actually am in love with him, right? Heh… Took me long enough to figure out something so simple.' – Uraraka thought but soon focused on the battle, for she was also preoccupied.

"WHY, YOU ASK?"

Izuku's voice filled the entire place, once again.

"BECAUSE I AM HERE!"

His voice made everyone, except Shigaraki to have goosebumps.

"I AM DEKU! YOU CAN DO IT!"

This last sentence won the hearts of everyone, still, except Shigaraki. That boy was standing alone against one of the biggest threats seen by humanity. Of course, he won the hearts of everyone.

He then charged at an even faster speed at Shigaraki, making a trail of light that obfuscated the light of the Sun.

He barraged Shigaraki, who didn't have time to react.

"I WILL NOT GIVE UP!"

Izuku screamed while barraging Shigaraki. After that, he focused all of his power, including all of his quirks and his determination.

"SMASH!"

The huge blast hit Shigaraki straight on, making him fly so fast that he was now outer-space.

Following that was a huge explosion, and the shock of that destroyed the walls of USJ. The aftershock even sent the helicopters a little behind, and they were very far from Deku. A trail of fire and smoke could be seen through the sky. The trail that Shigaraki left behind.

Blackmist quickly teleported everyone out of there. He had no time to choose who he'll teleport, so he saved 1-A with him. Blackmist saved them twice today.

Right after that, The reporters came back, and there, in the middle of the ruins stood a boy. Topless, showing all of his scars to the world. They, of course, streamed that.

The boy that saved them.

The boy that saved Japan.

The hero, Deku.

You can do it.

What will happen to them? Is Izuku fine? What happened to everyone there?
