A/N: This is my very first fanfiction, so please help review my work.

Also, this fanfiction isn't really to be taken seriously. This is just some random idea that I had one day, okay?

Atop of a random building, two individuals could be seen: Izuku Midoriya, a young man with green hair wearing a junior high schooler's outfit and his backpack, and All Might, the current number one hero, with his back turned from Izuku, ready to leave.

Memories flash through Izuku's mind, from the moment he was told he would be Quirkless, to his mother apologizing to him, to even earlier today, when Kacchan reminded him of how Quirkless he was. With his idol mere feet away, he just has to ask before the chance passes.

"Even if I don't have a Quirk, can I become a hero? Can even someone without a Quirk be like you?", he asked, closing his eyes.

Stopping in his tracks, All Might turned his head.

"... Without a Quirk?", All Might mutters, taking in what the young man had asked him. Suddenly, a familiar wave of pain surged through his body, which only meant his time limit was up. As he leaned against the railing of the building, smoke could be seen being emitted from his body. "Oh no, holy shit, goddammit!"

All the while, Izuku was obvious to what was happening. He kept his eyes on the ground, missing what was happening, and continued with his questioning.

"It might've been because I don't have a Quirk, but I'm always made fun of…

Maybe that's why… I don't know…, but I think saving people is super cool. Saving people with a fearless smile."

"I want to be the greatest hero, like you…!" With bright eyes, he looked up, only to be surprised by the skeleton-like man who appeared where All Might had just been. Staring for a few seconds, only one thing could come out of Izuku's mouth. "Uuwwwaaahhh?!"

One short explanation later

Izuku could hardly believe what was being told to him. The man he saw as the greatest hero was now in a weakened condition, all due to an incident five years ago that lead to only half of his respiratory system in working order. 'But if Toxic Chainsaw wasn't responsible, then what or who could possibly have done this?'

"I smile to show the pressure of heroes, and to trick the fear inside of me." All Might clenches his fist. He knew the responsibilities and risks that heroes take, as well as the consequences that come with failure. Turning to look at Izuku, he knew what he was about to say may seem harsh, but without a Quirk, there would be little chance that the boy will survive being a hero. "Pros are always risking their lives. I cannot simply say, 'You can become a hero even without power.'".

Like being struck with a knife, his words laid heavy in Izuku's heart. "I see…"

"If you want to help others, then you could also become a police officer. They're often teased because they get villains delivered to their doorstep, but that is also a fine occupation" All Might says as he gets up and begins to walk towards the roof exit. Opening the door, he stands there for a moment. "It's not bad to dream, but you also have to consider what's realistic, young man."

As he leaves Izuku on the rooftop with his thoughts, All Might walks down the stairway, coughing along the way. "Now, I need to quickly get this guy…?!"

Before being on the roof, All Might had been chasing after villain made of sludge-like material. Following a trail of sludge, he had saved Midoriya Izuku from being suffocated by said villain.

The one which he contained in a soda bottle…...

Which he placed in his pant's pocket….

Which was feeling very empty right now….

Suddenly, a boom could be heard and smoke could be seen buildings away from a window.

…..shit.

Tatooin Shopping District

Explosions ring out as glass windows break and the whole shopping district ends up in flames and debris. People within the district run away to avoid the destruction, while bystanders watch from a safe distance. At the scene, heroes arrive with the police, only to see a horrific scene.

Amidst the rubble and fire, the sludge villain could be seen. Within its body was a junior high school boy struggling to break free, but it was in vain.

"A child was taken as hostage?!" Angered at the villain's cowardice for using a child as a hostage, the hero Death Arms smashes his fists together and runs toward the villain. "You coward!"

He jumps into the air and lands a hard punch into the villain, yet the sludge villain felt nothing and was even pulling his arm into the sludge. To prevent himself from being enveloped, Death Arms tries to use his other arm to pull himself away, but he couldn't get a grip due to the villain's slippery body.

"What is this?! I can't grab hold!" As the hero struggled, the villain morphed part of his body into a limb and swung it at Death Arms. Immobilized, the hero was pushed away and was knocked hard into a metal wall, leaving an indent. "Guh! EEhhh.."

"Death Arms!" "Crap!" The other heroes there watched Death Arms be swatted away. As they called out to him, they were forced to back away as the villain fired a sludge arm at them to keep everyone else at a distance.

"Don't come near me!", the sludge said as it retracted its arm. Looking down to his hostage, he sees the boy free his face.

"Arrggghh! I won't let sewage like this swallow me! You little!" Taking action, the boy releases a few explosions and then causes a string of larger ones. Smoke and flames spewing every which way, the force of the blasts cause even some of the heroes to hold their ground.

As the blasts stop and the smoke clears, it could be seen that the villain held on and still had the hostage in place. The villain began to smirk at how lucky he was. "What power! I've hit the jackpot! With this Quirk and power, I can get revenge on that guy!"

Both the heroes and the bystanders could only watch in awe as the sludge began to go into a frenzy. "Woah, what's that?! Could he be a big-shot villain?"

"She's here! The rookie hero, Mt. Lady!", one of the bystanders exclaim, but it was short-lived. Because of her size, the rookie hero was unable to enter the fight. "W-wait… I need there to be at least two lanes!"

As the chaos ensued, other heroes could only help elsewhere. The hero Kamui Woods was extending his branches and carrying anyone who was still stuck in the flames and rubble. "I'm not good with explosions! I'll leave it to someone else for today!"

At the same time, the hero Backdraft was using his firehose-like arms to extinguish the flames coming from the outer buildings before they spread any further. "Thanks for that. I have my hands full fighting the fire. The fire truck's not here yet?" He turned his head to the heroes with the villain. "How are things over there?".

"He's sticky and hard to grab, and a child with a strong Quirk is struggling against him."

"Thanks to that, it's a minefield. It's hard to do anything against this triple play!"

As the heroes give their assessment to Backdraft, Death Arms, who was up from the villain's attack, flinched watching the hostage struggle. Seeing this as a sign of weakness, the sludge villain throws another attack at them, causing the heroes to fall back once more. "Crap!"

"It's no use! There's no one who can take care of this at the scene right now!"

"All we can do is wait for someone with a more suitable Quirk!"

"Let's hold back the damage until then!"

Don't worry, I'm sure someone will be here soon!"

All of the heroes at the scene agreed that they needed to wait it out, but it was still difficult due to the circumstances. Death Arms continued to watch and tightened his fist. 'I feel bad for that child, but he'll just have to bear it a little longer. Damn it! If only I had enough power to blow that guy away!'

At the same time, a lone figure observes the chaos unfolding from a distance with an unsatisfied look. They had come to this world in order to find the perfect test subject, yet was very disappointed.

'In a world with superheroes, this is just sad. Just keep standing around, you so-called heroes. By the time the cavalry arrives, the kid may as well be dead.' While thinking this, they themselves were quite the hypocrite, since they also were unmoving.

Although, they had a reason for this. They didn't know if it was fate or their gut telling them something, but they had a feeling that something special was going to happen soon.

At this moment, All Might, still in his skeletal form, finally reached the shopping district.

Catching his breath, he looks up to see the sludge villain reeking havoc. With widened eyes, he thinks back on how this could have happened. The only answer was when the young man hitched a ride while he was in mid-air.

'It was back then! I was too distracted by my time limit! I can't believe I made a mistake like this after admonishing that fan. Pathetic…' Thinking of how weak he was, he gripped onto the scar from five years ago.

Meanwhile

Izuku was walking down the road, looking at his notebook and not looking at where he was going. After hearing his own hero tell him that he couldn't be a hero, his mood was solemn. His mind felt like it was enveloped in fog.

"He still can't face reality, even though he's already a third year in junior high."

"It's time for you to think seriously about your future."

"You also have to consider what's realistic."

Closing his notebook, he gives a tired sigh. 'Even a top pro said it. Don't cry! You knew, didn't you?'

'The reality… You knew.' Izuku could see nothing ahead of him and walked aimlessly on an unknown path. 'That's why you were trying so desperately. You were averting your eyes not looking at reality.

Then, a sound of buildings being destroyed knocked him out of his trance-like state. Looking up, he sees smoke coming from across the street, as well as a group of bystanders watching something while police were clearing the area. He remembered hearing something explode and seeing smoke from the rooftop earlier. 'Is this where the explosion earlier was…?'

'Hang on, does that mean I came out of habit without noticing?' With weary eyes and a rapidly beating heart, he walks across the street to where the bystanders were. 'Stop it. It'll just feel meaningless right now.'

Looking past the many people watching, Izuku finally could see what was going on. With widened, scared eyes, he saw the same villain he met earlier that day that had tried to enter his body to use as a disguise. The sludge villain was in the middle of the shopping district, while the heroes were watching at a far distance. 'Why's that guy here?!'

'Did it get away from All Might?!' Flashbacks appeared in his mind and he remembered that All Might placed the villain's container in his pocket, but he didn't remember seeing the container while on the rooftop earlier. 'Did he drop it? If he did…...then it's my fault…'

While feeling the wave of guilt for causing the villain to escape, he couldn't help but overhear the conversions of the other people watching.

"Why aren't the heroes doing anything?"

"They can't. Apparently, the villain caught a junior high schooler. It's been like that for a while"

'Caught…? It's been like that for a while?" With this new found information, he guilty for getting someone captured and for how that person must be feeling right now. Remembering his own experience, he couldn't imagine how they could survive being suffocated. 'How can they bear that suffocation? I thought I'd die after a few seconds. Wow…'

"Anyway, wasn't that villain the one All Might was chasing earlier?

"All Might? No way! He's here?"

"I think I saw him earlier."

"Seriously?! Then what's All Might doing?!"

Both Izuku and All Might could hear everything that these civilians were saying. All lowered his head down in shame, while Izuku could only drown once more in his self-loathing.

'It's my fault…! He can't do anything! He can't catch that guy…'

'Pathetic.'

'All we can do is wait for a hero with a more suitable Quirk!'

'Pathetic…'

'Do your best! I'm sorry! I'm so sorry!'

'Pathetic!'

'Help will arrive soon…'

'Pathetic!'

'Someone… A hero… will soon…' Finally looking up once more, Izuku focuses in on the hostage's face. In that instant, both individuals made eye contact and time felt like it slowed down for a moment. Izuku knew who that was.

It was Bakugou Katsuki, his friend Kacchan.

He didn't know what happened, but suddenly Izuku dropped his notebook and went rushing in like a madman. All Might and the heroes there all watched in shock as a young man was running in, clearly a suicidal act in their eyes. "Idiot! Stop! Stop!"

"That brat…" The villain clearly remembered the boy from earlier. It was his fault for struggling for so long that led him to be captured by All Might.

"Deku…" Katsuki, in a weakened state from lasting as long as he did, saw Izuku running towards him.

Running as fast as he could, he avoided the flames beneath his feet. With adrenaline pumping through his body and fear in his eyes, he himself had no control over his body. 'Why did I run out? What am I doing?! Why?!'

"Die in an explosion!" Pissed off, the villain began to assault Izuku, ready to give a death sentence.

'What do I do? What do I do at a time like this?' Izuku knew he had to think of something quick, or else there will be two junior high students dead today. Images of a certain page from one of his notebooks surfaced in his mind. 'Page 25!'

Going on the attack, he shifted his weight so his backpack went over his head and launched it, and all of its contents, and the sludge villain. "Take that!"

"Wwuuaagghh!" The villain was not anticipating this move and was hit in the eye by one of the books inside the bag. This moment was all it would take for Katsuki to free his face and breath once more. " *cough* *cough*"

"Kacchan!" Being close enough, Izuku began to claw away the sludge, in hopes that this could help Katsuki escape.

"Why are you here?!", Katsuki yelled.

"My legs moved on their own! I don't know why, though!" While Izuku kept digging in, Katsuki was once again being enveloped in sludge.

Through all of the reasons he could possibly think of, there was only one that really made him move as he did.

"You looked like you were asking for help…" Looking up, Izuku had tears running from his eyes.

The lone figure smirks at the boy who had run into the middle of it all. Seeing as how the boy used his backpack as a distraction instead of his power, they could only deduce that either the boy's power was too weak or he had none.

But power or no power, he was showing that he was stronger than those other heroes, in both heart and soul.

"Finally, someone with some backbone! Such courage in such a small body! Well then, you'll make the perfect test subject." Reaching into their pocket, they withdraw a gun-like object and point it towards Izuku, who was still trying to dig the hostage out. Firing at him, a small device clings onto the back of Izuku's neck, slowly embedding itself inside the body, yet painless and unseen. "Now young man, let's see if you can activate Dr. Otowa's little invention shall we? Better do it quickly as well."

With a look of interest, they waited for the moment of either a miracle or a tragedy.

Katsuki, hearing the words come out of Deku's word, was only enraged even while struggling. "Stop it!..."

Unbeknownst to the two boys, the sludge villain had finally recovered from his injury. The villain had thought of killing the brat right now, but he could see this as a bigger opportunity. Though he couldn't take over two bodies, he may as well finish the job that he started earlier that day to relieve the humiliation from being captured.

In a single motion, the villain sludge arms gripped Izuku's legs, causing the boy to stop clawing, and engulf half of the brat's body.

"Uuuaahhh!", as Izuku was being dragged inside, he couldn't help remembering the suffocation. He knew what was to come if he was completely captured. 'No, not again!'

In this time of fear, he looked at the many faces watching him.

The heroes whose faces showed helplessness in their ability to act.

The bystanders whose faces showed sorrow for what the boys were going through.

Even Kacchan, who, in all of their time together hurting him, had a look of fear for his sake.

He couldn't let it end like this. Beyond all of the guilt, self-hate, and fear, a spark had ignited inside him. 'I won't let Kacchan go down like this. Even after everything he's said, I can't hate him.

'He is my friend, so I won't give up.'

'I can't stop.'

'I won't stop!'

In the background, All Might had heard Izuku and could see now that he hadn't been listening to his own words. With renewed vigor, he, with his muscular form, was about to enter the scene, when a bright light blinded everyone.

"What in the…?!" The sludge villain was the first to open his eyes to try to see what the hell was that. Looking around, his gaze found its mark on the brat, who had something in his hand. 'A stick?'

'Is this a Quirk?' Staring at the baton in his hand, Izuku had no idea as to where it had come from or if this was his Quirk that had manifested very late. The only thing that he knew was that this was here to help him.

Raising the baton to the sky, a phrase repeated itself in his mind. It was as if it was telling him to say it. With nothing else to lose and the flame in his heart, he yelled out the words for all to hear.

"Spielen wir unsere Musik!" ( let's play our music! )

In a flash, red ribbons appear from nowhere and surround Izuku, releasing him from the villain's grasp. The ribbons then open up to reveal a standing Izuku with eyes closed, wearing a black conductor's outfit with red trimmings.

All were quiet, astonished at what they had seen, except for the villain behind Izuku. After all of that, the kid only had a wardrobe change? How laughable! May as well kill the useless kid. "Nice clothes kid, real formal! They'll be perfect for your funeral!"

Just as the villain began to strike once more, Izuku raised the baton again. The moment the baton was swung, music blared throughout the street as musical notes spun around in the air.

Atsuki jounetsu o, Hisoyaka ni azayaka ni dakishimete
Hito wa ikiru kaze no naka, Mayou hibi wo "tabi" to nazuke

The musical notes zipped past the villain and encircled some of the broken cars and appliances that were among the debris. The cars floated in the air, collided with appliances, and merged to become some kind of scrapyard robots.

"Wow!" "Amazing!" "What is actually happening?!" The bystanders, police, heroes, even the main villain himself were all mesmerized by both the machines and the music. They could not what was happening before their eyes

Tsukameba kuroi suna ni nari, Yami ni kieru yume yo
Korinai yatsu da to, Saa, azawarau ga ii

The robots turn toward the villain and lunged forward. The sludge villain then remembered his situation and tried to dodge, but was too late. Two of the robots with vacuums as arms had turned on the suction. "Aaaggghhh!"

As more robots came to tear the villain apart, one of the robots thrust an arm into the villain's belly. Pulling back, it was able to retrieve Katsuki, who was still short of breath and staring at Deku.

Zetsubou koso ga maboroshi da
Yowaki kokoro furuitatase Ore wa koboshi o tsukiageru
Unmei yo hizamazuke Kiseki wa mou okiteiru

In a last-ditch effort, he went straight for Izuku. If he could kill the boy, then the robots in his control will surely stop as well! Even if he doesn't escape, he will at least take the boy down with him! "That is it! I am tired of this! If I'm going down, then I'll send you down as well!"

"I don't think so!" Before he could try, someone appeared to block his way. All Might, who wanted to at least protect the boy who reminded him of what a hero truly, stood ready to fire a punch.

"All Might! Detroit Smash!" Punching the villain, he sends the remains of the villains flying and scattering the remaining sludge to who knows where.

Passion... Passion...
Spielen wir unsere, Spielen wir unsere
Musik, Musik, oh…

As the music finally stops, Izuku's outfit turns back into his school uniform and the robots that were created by the music returned back into the broken cars and appliances. Everyone stares in silence as rain falls due to All Might's punch.

Shortly after, the street is filled with cheers for All Might, as well as a few for both Izuku's and Katsuki's bravery in such a situation. All Might raised his arm as a sign of triumph, causing more people to cheer louder.

But as the cheers keep coming, Katsuki could only stare at Izuku, internally enraged because of the fact that apparently Deku wasn't some weak, Quirkless kid and had hidden it since elementary. "Fucking Deku! You have a lot of explaining to do asswipe!"

Just as Katsuki put a hand on Izuku's shoulder, Izuku suddenly slumps and falls to the ground.

"Oi, Deku! Wake up!"

"I said wake up!"

"Deku? Deku!"

'Heh, heh. Just as I thought.' The figure saw everything and the young man met all of his expectations! Too bad that the kid went unconscious though. Must of been too strain on his mind and body. 'Well then, I guess I'll have to meet him later when he wakes up. In the meantime, I'll just run a background check.'

The figure disappears as the bystanders scatter, leaving a premonition of more to come.
