The Sword Hero: Exia

Musutafu, Japan.

In the city market district, several explosions rocked the district. A group of civilians are gathering near the market entrance as they are watching something inside the district.

"Arggggghhhhh!" The sound of a boy yelling can be heard from inside the district as turns out the boy is being wrapped by some sort of living slime.

"Damn you! Die!" The boy yells then he creates a massive explosion from his palm.

"Hehehe, nice try" The slime smirked before it tried to wrap the boy even more.

On the sidelines, are several people wearing costumes with several unique body parts.

"Damn you! You're using a human shield!" A big muscular man curses before he moves toward the slime and punches him, only for his punch to be absorbed by the slime. The slime then moves the boy's hand and creates an explosion toward the muscle man, making him fall back. "Damn! I can't get close and my punches aren't effective enough. Hey! I need help here" The muscle man requested.

"I can't. I would be burned if I get close" A man with wood all over his body said.

"I'm busy with the fire here!" A man with a fire hydrant-looking costume said as he pointed his hose-like hands to extinguish the market that gets on fire by the boy's explosions.

"Narrow street, my only weakness. I need at least 2 lanes" A giant lady said outside the market district.

"Damn it! None of us has the right quirk for the job. Sorry, kid. Hold on a little longer until more heroes arrive!" The muscle man yells at the boy.

"They can't save the boy?" A civilian bystander asks.

"I don't think any of them can" Another bystander replied.

"That boy has a good explosion quirk, but he is making his own rescue difficult if he continues to throw random explosions like that" A bystander claims.

"And he also the one who set the stores on fire as well" A bystander claimed.

"But he doesn't do that intentionally. If he is saved, he'll be hailed as a young hero who survived the impossible" A bystander claims smiling.

In the middle of the civilian bystander, a boy with fluffy dark-green hair, symmetrical freckles on his cheeks, and wearing rather worn-out clothes is staring at the scene while gritting his teeth and clenching his fists 'Hero? No... he... he...' The boy thought as he watched the explosive boy struggling to escape the slime grasp.

Near the street at the back of all the bystanders, a skinny skeleton-like man just arrived there after running. He pants before he looks at the scene 'How this happened?! Did I lose him during the jump? I already use all my time! I don't have enough energy left! I am pathetic!" The skeleton man curses himself.

'He is...' The boy thought as he appeared to have a lot on his mind as he began to hear noises in his head.

'I'm sorry, kid.'

'He doesn't have a quirk?'

'Waste of space.'

'A disappointment.'

The boy closes his eyes as the noises are apparently some bad memories of the boy's past.

'Weakling.'

'Useless.'

'Quirkless.'

The boy opened his eyes and gritted his teeth as he grabbed something from his duffle bag.

"I am..."

Earth, 2050 A.D.

It's been 30 years since a supernatural event happened that changed the human race forever, Quirks. People who were born with abilities that are often impossible to understand by logic. Some are harmless, some are destructive. The world order was thrown into chaos by the sudden appearance of quirk. It took a decade before all the panic and confusion subsided, and humanity accepted quirks as a part of the next human evolution. The next 20 years were filled with a relative uneasy peace between those who have quirks and those who don't. There is tension between the two sides, but mostly peace is achieved. Until it wasn't anymore.

30th August, 2050, Tokyo, Japan.

A quirk extremist group launched a series of terror attacks all over Tokyo, claiming it to be a wake-up call for the quirked people to rise against the oppression. The day when the quirked finally declared the "Quirk Uprising." The attacks were so devastating that the entire Kanto Region was declared martial law and the Japan Self Defense Force was mobilized to deal with the extremist group. The "war" lasted for 13 days with the cost of almost half of Tokyo being destroyed and thousands of lives lost.

The aftermath of this event marked a large change in the world for the first time since quirks started appearing. A new law dictates anyone who possesses quirks, that public display of quirks is against the law, except in the cases of self-defense, such as when one is under attack. Or have special permission from the government for productive activities.

And one permission stands out as it has been the spotlight for the new world order for the last 170 years. A permission for an individual to use their quirk to fight for others, to protect the masses, to do what is right. A career once thought impossible and fictional, a career of being...A Superhero.

"A hero!" The boy claims he surprised the people around him.

"What?" A bystander said confused.

"What is he talking about?" A bystander asks another bystander.

"Is he okay?" A bystander asks confused and worried

The boy then grabs something from his large duffel bag. The sound of a machine can be heard from where the boy is, confusing the people around him

The muscle man glanced back as he heard the boy yell 'What is he doing?' He thought. "Hey, kid. What are you..." The muscle man didn't finish as the boy suddenly ran past him and the wooden man towards the slime.

"What are you doing?!" The wooden man yelled in surprise.

"Comeback, kid!" The muscle man yells as he tries to grab the boy to no luck.

"Wait, that kid!" The skeleton yells in surprise as he recognizes the kid, but he also notices a device on the kid's right arm 'What is he wearing?' He thought.

The slime notices the kid is running towards him "Hoo? Do you want to join us? Ah, but this kid already has a good quirk" The slime said as the explosive boy tried to escape so hard from him.

As the boy is dashing toward the slime he remembers something from his past.

"Izuku, you might be quirkless, but you are not useless," A man told a younger version of the boy, now known as Izuku.

"But... but everyone said I am..." The young Izuku said with wet eyes as he was crying.

"Izuku. A quirk does not define who you are. What you do, what you say, what you achieve, that is what defines you" The man told Izuku before he kneeled in front of Izuku. "And remember this, Izuku. That a quirk..." The man said seriously."

I'll take you as well!" The slime said as he launched several tentacles towards Izuku.

"...Is just a tool!" Izuku cried as the slime tentacles approached him.

The device on Izuku's right arm is engaged and deploys a large sword. Izuku then stopped abruptly before he swung his right arm up and sliced the slime's tentacles.

Once seeing what just happened, everyone is surprised.

"What the...?!" The muscle hero yells in surprise.

"Is that..." The giant hero said in surprise.

"A sword...?" The skeleton man said in surprise.

"Eh...?" The slime said surprised for a second before he realized what just happened "You bastard!" The slime is enraged as it launches several tentacles toward Izuku.

Izuku dodged some of the tentacles and sliced a few before he dashed forward then slid down, avoiding several tentacles before he sliced them tentacles and then jumped up.

The slime launched several more tentacles toward Izuku, but Izuku parkour passed some tentacles while slicing some and getting closer and closer to the slime and the explosion boy.

The heroes and bystanders are surprised by Izuku's sword device and sword skill.

"Grah! You are so annoying!" The slime yelled irritated then he created a slime wall in front of him.

Izuku dashed towards the slime wall then vertical slice the wall before he spun right and horizontal slice the slime wall. Just as the slime wall is sliced off by Izuku, an explosion suddenly comes from behind the slime wall and knocks Izuku away.

"Damn!" Izuku groans as he flies back from the explosion's shockwave.

"Kid!" The muscle hero yells in surprise.

Izuku landed on the ground a few meters back and slid for a few more meters before stopping "Tch! I let my guard down" He groaned in pain.

'What is he doing risking his life like that?' The skeleton man thought before he realized something 'He's risking his life... while here am I, The Number One Hero, letting the rookies and a civilian make up my mistake...!' He thought angrily.

"Kid, get out of there! Let us handle it!" The muscle man yells at Izuku.

"Oh, you are handling this very well" Izuku replies sarcastically as he tries to get up.

"I got you now!" The slime yells as he launches several tentacles toward Izuku.

Izuku gritted his teeth before he rolled back making the tentacles to struck the ground instead. Izuku gets up, only for an explosion to launch towards him. Izuku then jumps back before he is far enough from the slime and hostage boy.

"That slime villain! He is using the hostage's quirk to attack the boy!" The wooden hero claim.

"Kid, get out of there, now! You've done enough!" The muscle hero yells at Izuku.

Izuku grimaces and retracts the blade on the device, but then he raises his right arm toward the slime and points there like he is aiming the slime.

"Just give it up, kid! You've annoyed me enough!" The slime claimed then he launched several tentacles toward Izuku.

"Kid, get back here!" The wood hero yells.

Izuku only stared at the slime tentacles as he put his index finger on a trigger on his arm device. Izuku inhale then he slowly exhales a cold misty breath.

"Engaging" Izuku simply said then he pulled the trigger and a pinkish laser beam shot out from his arm device, disintegrating the slime tentacle.

"Ahhhhh!" The slime screamed as if he felt his limbs being torn off.

Once again, the heroes and bystanders are in shock of Izuku. A sword device, sword skill, and now a laser beam? Who is this guy and what the hell is that device that he uses.

Because of the slime being shot by Izuku, he started to lose grasp on the explosion boy hostage. The hostage boy finally manages to see outside since the slime is off his head, he is about to yell at the slime when he sees Izuku firing at the slime with his arm device. The hostage's eyes widen in surprise.

"I... Izu... ku..." The hostage boy said in surprise as he recognized Izuku.

Izuku continued to shoot the slime over and over until he heard a beeping sound from his device, he looked at a small display on his device and it displayed that the device had almost run out of particles. So Izuku stops shooting and lower his arm.

"W-What was that...?" The wood hero said in surprise.

"I don't know..." The hydrant hero replies in surprise.

"Laser beam?" A bystander said surprised.

"It doesn't look like a quirk..." Another bystander said.

"It came from the kid's arm device" A bystander pointed out.

"A support device?" A bystander wonder.

"It doesn't look like a support device to me. The way that kid uses it... it's like a main armament instead" A bystander claims.

The skeleton man clenched his left hand on his stomach 'Young Midoriya... the way you use that device and the way you fight... you are...' The man thought.

The slime seems hurt but manages to recover as he regenerates the shot-off parts of him "I change my mind. I'll kill you!" The slime yells as he charges forward with the hostage.

Izuku then deployed the sword again and charged forward.

"Kid...!" The muscle hero yells.

The slime launched several slime tentacles toward Izuku. Izuku sliced tentacles left and right before he jumped and somersaulted in mid-air before he heavy vertical slice down on the slime without hitting the hostage. The slime grunted in pain while the hostage only watched in shock before he noticed something.

"Move!" the hostage boy yell gaining Izuku's attention.

Izuku looks up and sees the hostage's arm pointed at him. Next thing he knows, an explosion blasts him back 'Damn! Again...!' He thought as he flung into the air.

"I'll kill you!" The slime screams as he raises a large slime tentacle to strike Izuku mid-air.

"Nooo...!" The hostage boy muffled a scream.

"Damn...!" Izuku curse his luck as he was unable to move mid-air.

'I have to do something, no matter the cost!' The skeleton man claimed as his body began to expand and steam came off from his body.

"Huh?" A bystander said confused as he noticed steam coming from the skeleton man.

The heroes finally dash toward the fight.

"Save the boy! The villain will kill him!" The muscle hero yells.

The slime strikes Izuku with his tentacle. But suddenly, something moves at high speed past the running heroes and towards the fight. This something then blocks the slime's tentacle as a dust cloud surrounds them.

Izuku landed on the ground, unhurt from the tentacle. He looks up and sees a giant muscular man with blond hair and two tufts that stick up above his head making a V shape and a wide smile holding back the slime's tentacle.

"I am really pathetic" The giant muscular man claimed.

Izuku's shocked expression is quickly replaced by a sour one and he faces away from the man with a frustrated look.

"I'm sorry, Young Midoriya. I didn't live up to my words" The giant muscular man claimed.

The hostage's eyes widen in complete shock "I... I... Iz..." He tried to say something by he was too shocked to say it.

"Is that..." A bystander said in surprise at the giant muscleman's sudden appearance.

"All Might...!" A bystander said shocked.

"That's All Might! The All Might!" A bystander claims in shock.

"The Number One Hero, All Might!" A bystander claims excited about the giant muscle man known as 'All Might.'

"Holy crap... It's All Might..." The wooden hero said in surprise.

"He was here...?" The giant hero said confused.

"All Might..." The muscle hero said shocked.

"I'm sorry for being a hypocrite, Young Midoriya" All Might apologize "Now let me make up for my mistake" He claimed before he faced the slime.

"Damn you, All Might!" The slime tries to attack All Might.

All Might grab the hostage inside the slime and cock his right arm "Detroit... SMASH!!!" All Might pulled the hostage out of the slime and punched the slime with a large force that it simply blasted away the slime. The wind pressure created by the powerful punch rocked the entire market district. The wind pressure then created a giant tornado inside the market district as everyone took cover.

All Might put the knocked-out hostage down before he kneels down, breathing heavily while Izuku just stands beside All Might, and the heroes and bystanders watch in total silence.

A water droplet fell from the sky, then more droplets fell from the sky then soon, it started to rain in the area.

The muscle hero look up to the dark sky "Holy crap... he changed the weather" He said shocked.

All Might wipe a drop of blood away from his mouth before he stands up. The bystanders then began to clap and cheer as the fight was over in the most dramatic and epic way.

All Might stumbles back a little but manages to recover before he raises his fist to signal his victory, this only increases the bystander's cheering. All Might give a smile at Izuku, but Izuku looks away before retracting the sword.

Later, the slime villain, inside some small containers is taken into custody as more heroes and police arrive at the market district.

The heroes who were already present during the first commotion salute the police who take the slime villain away in their patrol cars.

All Might is busy with the press and civilians who interview him and fanboy him.

Meanwhile, Izuku is releasing his arm device and putting it back inside his large duffle bag when three heroes approach him.

"Do you have a death wish?!" The muscle hero/Death Arms scolded Izuku.

"There was absolutely no reason for you to put yourself in danger like that" The wooden hero/Kamui Woods scolded.

"While I admit that you have guts. You use that guts in the wrong place, kid" The giant hero/Mt. Lady scolded.

On the other spectrum, the hostage explosive boy has already woken up and is being praised for his bravery and persistence during the incident. A hero is praising the boy and asking him to work him to work with his agency once he graduates from a hero school. But the boy shows no interest as he stares at Izuku with deep thought before looking away.

Having enough of being scolded, Izuku stood up "What are you going to charge me for? Illegal use of quirks? Being a vigilante?" Izuku asks rather angrily and sarcastically.

"Why are being so sarcastic? Of course, you will be charged with those" The muscle hero said angrily.

"And how are you supposed to charge me for illegal use of quirk... if I don't have one to begin with?" Izuku said coldly.

This surprises the heroes and the people around them. The explosive boy perked up and looked at Izuku's surprise.

'Quirkless...? Is he really...?' The explosive boy wonders about something.

"Wait... you are quirkless?" The giant hero asks in surprise.

Izuku grabbed his wallet and showed his ID to the heroes. The wood hero grabs Izuku's ID and it shows that the quirk part says: Quirkless. Izuku is really quirkless.

All Might dropped his smile a little as he stared at Izuku with a both sympathetic and guilty look.

The bystanders began to whisper one to another.

"He is quirkless..."

"But he doesn't look like it."

"But what about his moves during the fight? He looked like he had an agility quirk at least"

"So he only relied on his support device to fight."

"Then he was only lucky that All Might saved him."

"Yeah, he is an idiot to try to fight with only a support device."

"Too bad, I was thinking I could recruit him. But that goes up in smokes."

"What was he trying to do? Prove that without a quirk he still could be a hero?"

"What an idiotic way of thinking."

Izuku looks down as he already expects them will react like that. They will focus on him being quirkless despite what he has accomplished.

Kamui Woods shook his head while still holding Izuku's ID "Kid, you are really-" He didn't finish as Izuku forcefully grabbed his ID from Kamui Wood's hand.

"If you don't have anything else, we're done here," Izuku said annoyed before he walked away.

"Wait-" Death Arms tries to grab Izuku when All Might put his hand in front of him.

"Don't. He has done nothing wrong" All Might claim, letting Izuku walk away.

"But, All Might..." Kamui Woods tries to argue.

The hostage boy gets up and tries to chase Izuku, but paramedics prevent him from doing so, claiming that they have to inspect him first. Frustrated, the boy could only watch Izuku disappear from his view.

Several blocks away from the market district, Izuku is walking away, presumably back to his house.

'Well, today is... sigh...' Izuku sighed when he heard something.

"Izuku!" Someone called Izuku's name, Izuku already knew who called him, it was the hostage boy from earlier.

The hostage boy stops in front of Izuku while panting heavily "Izu... Izuku... hah... hah..." He pant.

Izuku took a deep breath before turning back towards the boy who was chasing him "Hey, Katsuki" Izuku greeted the boy.

The boy, revealed to be Katsuki is still panting but he looks both surprised and angry at Izuku.

"I'm sorry our fateful reunion has to be like that" Izuku apologized.

"You... you..." Katsuki still panting before he took a deep breath and breathed out quickly and stared at Izuku "I thought you were dead" He said.

Izuku only stared at Katsuki with a flat and somewhat sour expression "Sorry to disappoint" He said with a sad smile.
