(Chapter 1)

( - )

He was falling.

That was the first thing he became aware of as his eyes flickered open.

Wind was rushing around his body and roaring in his ears as he hurtled through the air.

He wasn't sure how far up he was, but the people walking around the city below looked like fleas.

Blinking, he felt his eyes begin to water as the wind whipped past them.

Where was he?

And more importantly, why was he here?

He couldn't remember any of the events that led to him being here.

The last thing he remembered….

He wasn't actually sure….

Frowning slightly as he continued to hurtle through the air, an odd sense of bemusement filled his being as he came to a sudden realisation.

He was about to die, but despite that, for some reason the thought of dying didn't bother him?

Was that crazy?

The ground was getting closer now.

Through the roar of wind in his ears, he could hear the buzz of the city around him as he fell and the beeping of nearby cars.

Turning his head, his eyes widened, and a slight smile graced his lips as he caught sight of his reflection in the glass that coated the outside of one of the large skyscrapers he was passing.

Short blonde hair, sky blue eyes and tanned olive coloured skin.

Those were the first thing he noticed, as he idly inspected his reflection.

A mucky, ripped up purple t-shirt, a pair of frayed jeans, some battered boots and a tattoo of a SPQR on his arm.

Those were the next things he took note of as he looked at his reflection.

None of it surprised him, as he definitely recognised himself.

He was Jason, Jason Grace.

Smiling to himself in spite of his impending doom, he took solace in the fact that he knew his own identity. His memory might be a mess right now, but at least he knew his own name. It was an odd thought to have with his demise so close, but honestly, he couldn't being himself to care.

He didn't know why, but for some reason he felt tired, tired of living maybe? He wasn't sure. Either way, he was too tired to even care that these were probably his last moments of life.

His lips twisted bitterly at that thought, even as he heard a shriek from down below.

It seemed at least one of the city goers had caught sight of his impending doom.

Extending his arms as he fell backward, he closed his eyes and waited for the inevitable impact.

At least it would be quick.

He didn't know himself all that well at the moment, but he at least knew that he didn't want a long, drawn out death.

"Got you!" A voice suddenly interrupted his introspection.

He felt something hit him in the side, his body twisted as he felt a pair of strong arms grasp onto him. The force of the blow knocked the air out of his lungs, even as the momentum from his fall was suddenly stolen away.

Opening his eyes, Jason watched the world spin as he and the person holding him hit the ground and rolled.

He felt his shoulder cry out in protest, and felt the air explode from his lungs as they continued rolling before with a heavy thud they hit the concrete parapet of a multi-storey car park and finally stopped.

"Ow," Jason rasped, his eyes closing as he felt the strong arms shove him away. His head smacked against the hard, asphalt beneath him.

"Serves you right, idiot." A brusque voice broke through his confusion and pain. "What the hell were you thinking jumping off the top of a building like that? For one, life is precious and no matter how shit it might be, suicide is a stupid cowardly way out. And two, what the fuck were you thinking? You could have hurt who knows how many people on the streets below, and probably traumatised even more! If you are hopeless and stupid enough to top yourself, at least do it in a way that doesn't endanger other people!"

"Urgh," Jason replied, moaning as he forced his eyes open.

He wasn't sure what hurt more; the physical pain, or the verbal tongue lashing he had just received.

"What was that, idiot?" The voice shot back impatiently.

"I didn't jump off a building," Jason bit out as he forced his eyes open, and finally got a good look at his saviour.

It was a tall, powerfully built, and scantily clad, Asian woman, with intense crimson, red eyes, long white hair, and what looked like two rabbit-like ears poking out the top of her head….

"Oh really, then did you fall or something? Because I don't see how else you could've got yourself into that kind of idiotic position?" The red eyed woman snapped back, her face twisting into an irritated snarl as she leapt to her feet and started flexing and stretching her unusually muscular legs.

Glancing at her legs, Jason felt his eyes widen as he noted she had unusually large, rabbit-like feet.

"My eyes are up here, perv." The woman added as she gave him an expectant look.

"I don't know how I got there, I just woke up, and I was falling… I don't even know where here even is or how I ended up falling, or well, anything, really…." Jason replied honestly, as he grudgingly tore his gaze away from the woman's shapely legs and instead began to try and push himself up and onto his feet.

"Stay down, idiot." The woman commanded, a soft but powerful hand came to rest on his shoulder, pushing him down. "You don't know what damage has been done. Nothing looks broken on the surface, but you might still have some internal damage, or fractures or something, that aren't outwardly visible. So you're going to stay down until a paramedic checks you over, you got that?!"

Her tone seemed softer and less angry.

Looking up, Jason saw a hint of both curiosity, and also what looked like concern in her fierce red eyes.

"I'm fine," He replied, as he tried to shake off her hand.

He didn't have much luck.

The white haired stranger was a lot stronger than she looked.

"And how would you know that, idiot? Are you a doctor?" She demanded in response.

"No," Jason replied.

"A nurse?"

"No."

"Do you have any medical training at all?"

"Yes." Jason cut in, a grin gracing his face for a moment, only for it to fall seconds later when his brow furrowed in confusion. "I think… or at least I'm pretty sure I do…"

"Uh huh," The red eyed woman replied bluntly. "Are you suffering memory loss? Did you hit your head?"

"No, or at least I don't think so." Jason said, his brow once again furrowing.

The white haired woman looked unconvinced.

"Alright then, what's your name?" The woman demanded, as she folded her arms.

"Jason Grace." Jason shot back. He knew his name.

"Alright, and how old are you?" She questioned.

"Sixteen…" Jason said slowly, his brow furrowing as she tried to remember if that was right.

"Uh huh, so you're a lot younger than I thought…. Okay, and where are you from, Jason Grace?" She asked.

"Rome," He replied instantly.

He had said the first thing that entered his head because It felt right. Yes, he was definitely from Rome. He remembered the coliseum and the city, and how lively and exciting it was. He remembered visiting it during the weekends with his friends, and how he had been planning to go to college there. Though now that he thought about it, he could also remember that he didn't live in Rome itself, but instead in a camp just outside the city proper, a military camp from what he could recall…. Did that mean he was in the military?

"Right, Italian." The woman nodded, her eyes narrowing. "You speak surprisingly good Japanese for a foreigner, you're practically fluent. How long have you been living in Japan?"

"Japanese?" Jason scowled, confused. "I'm not speaking Japanese, I'm speaking English."

The woman tilted her head to the side, unimpressed. "Alright idiot, first off you're in Japan, speaking to a Japanese hero, in Japanese…. How do you explain that? Unless you have some kind of Quirk that lets you instantly learn new languages?"

"Quirk?" Jason asked, his eyes narrowing as he tried to work out what in Jupiter's name was going on.

He was in Japan, and could somehow speak Japanese?

Since when?

Also, what was a Quirk?

And perhaps more importantly, why was the woman calling herself a hero, and moreover, why did her referring to herself as such irritate him as much as it did?

"A Quirk, you know, a superpower?" The woman asked irritably, flicking some of her long white hair out of her face, and behind her back as she scowled down at him. She didn't look impressed.

"I-I don't know," Jason said slowly, once again making to stand up.

"Back down," The woman muttered, her hand once again on his shoulder as she tried to stop him from standing.

Tried being the operative word, as this time Jason didn't let her have it all her own way as he instead got his legs under him and powered his way to his feet, the motion making the white haired woman stumble, even as she instinctively seemed to settle back into a fighting stance.

Wait, how did he recognise that as a fighting stance?

Pushing that thought out of his head, Jason steadied his foot and met the white haired woman's scowl with one of his own. He'd nearly died, and was confused, and his back and shoulder hurt. He wasn't in the mood to be interrogated.

"You lied, you have a Quirk." The woman said bluntly, her eyes sharper now as she watched him cautiously.

She seemed surprised that he had defied her and was eyeing him warily, like he was a coiled snake just waiting to strike.

"No, I'm pretty sure I would know if I had a superpower." Jason replied. The word superpowers didn't sound right.

"Then how do you explain overpowering me?" The woman demanded with a scowl.

"Well," Jason said, glancing at the short, but powerfully built woman, before he looked down at himself. Now that he looked, he immediately saw that he had a powerful build, with wide shoulders, thickly muscled thighs, and a strong abdomen. It led further credence to him having a military background. It also explained why the woman thought he was older than he was. "I mean, you might be older than me…"

The woman scowled.

"I'm nineteen." She bit out coldly.

"But," Jason pressed on, pushing down a slight shiver of cold he felt at her frosty tone. He sensed she didn't like him at all. "I am a guy, and I'm not exactly a thin, reedy guy either…"

The woman glared challengingly in response. "I could snap you in half if I wanted too."

"Please don't," Jason replied.

The woman's red eyes narrowed a fraction, even as a smirk spread across her expressive face at his response. "Alright, idiot. If you want to stand up and potentially fuck yourself up, that's on you. But no matter what, you're gonna wait here a while for a medic, as your head is all kinds of messed up."

"And how do you figure that?" Jason asked.

"Well you didn't know you were in Japan, didn't know what a Quirk was, you didn't know you were speaking Japanese, and I'm also pretty sure that you don't know how old you are." The woman rattled off.

"I said sixteen," Jason shot back.

"But you're not sure." The woman smirked.

Jason grunted in response. "Alright, fine. Thanks for saving me, I suppose…, and what's your name anyway?"

"I'd say I was offended that you didn't already know. But considering that you're probably lucky you even know your own name, I'll let it go, for now. The names Mirko, and I'm the best damn Pro Hero you'll ever meet!" Mirko grinned back at him, her gloved hand raised as she offered him a handshake.

A bemused smile spread across Jason's face as he tentatively took the proffered hand.

Her handshake was strong and firm.

"Nice to meet you, I guess."

(Sometime Later)

"Well, he's not got internal damage," Doctor Nakamura said mildly, as he looked through the observation window at the blonde teen, as he lay back on his hospital bed. He looked bored and antsy, and he couldn't blame him, as he'd been here for a while now. But thankfully he hadn't acted out, or at least not yet.

Looking back down at his tablet, he checked through the results of the MRI scan again.

Jason Grace was an odd one.

He'd come in for a routine check up after a paramedic had raised concerns about him having a possible head injury.

A scan showed no swelling on his brain. There were no abnormalities, tumours, or anything at all to raise concern, and yet he was still suffering from memory loss, even if he consistently claimed otherwise. Which perhaps suggested a psychological reason behind his partial amnesia, maybe?

Further scans and tests that had been taken when examining him for internal injuries had revealed that his bones and muscles were unusually dense, which suggested he had a mutation Quirk that gave him enhanced strength and durability. Additionally, his organs were hyperefficient, and the neurons in his brain operated at far higher capacity than normal. He had only seen its like before in individuals that had been born with intelligent Quirks. From what he could see, Jason Grace had a highly refined and versatile mutation Quirk.

But that wasn't what made him odd.

No, what made him odd was the fact that he lacked any and all identity.

They had taken retina scans and fingerprints, and had tested them against the national biometrics database. He didn't show up either as a native of Japan - all of whom had their biometrics added to the national database during their childhood - or on the immigration database.

There was no record of Jason Grace entering the country through any of the legal channels.

Upon learning that, they had had no choice but to call in the authorities.

Only when the police interviewed him and ran his biometrics through the Italian databases, they also came back with nothing. A few hours later, and after checking against the international criminal database, and the databases of the one hundred and forty three countries they had bilateral agreements with - all of whom followed international protocol by registering the DNA and biometrics of all their citizens -, they once again came up with nothing.

For all intents and purposes Jason Grace didn't exist. He had no nationality.

That said, he had distinctly caucasian features with blonde hair and blue eyes, which suggested a northern European heritage, but he also had olive coloured skin which was more in line with a Mediterranean skin tone, which led more credence to him being Italian.

But that was all they could really intuit, as he had no other nationality indicators to speak of, and his accent…. Well his accent when speaking in Japanese was indistinguishable from his own, or at least when he was speaking to him. The police, doctors and nurses who had spoken with him, had all said the same.

He seemed to perfectly mirror and absorb the accent and language of whoever he was speaking with.

He was an auditory chameleon.

A test of his DNA to check out his genealogy came back with nothing, as in they received nothing but errors.

Which, he assumed, was due to his mutation Quirk.

He didn't even have the extra joint in his toe, which was a general signifier of whether the individual had a Quirk or now.

Rubbing his brow, he sighed and lowered the tablet.

Jason Grace was an odd case, and he honestly didn't know what to do with him.

There was nothing medically wrong with him, or not that he could see.

The only thing he could keep him in the hospital for was his partial memory loss. But even then, he wasn't sure what they could do for that.

The patient wasn't a citizen, nor did he have insurance. So, without any underlying danger to his life, there was nothing they could really do for him. They couldn't even call in a psychologist, as who would pay for it? Nor could they keep him here by claiming he was under suicide watch either, as from just a cursory conversation with him, he could tell he wasn't suicidal and that he hadn't jumped off a building.

No, unfortunately, they had not choice but to discharge him into the police's custody, so he could be processed as an illegal alien.

What would they do with him, though?

He had no idea.

He had no nationality, so there was nowhere to deport him too, and with him having committed no crime they couldn't imprison him either. The best they could do is stick him in a migrant detainment centre, and leave him there to rot and be forgotten about.

He rubbed his temple at that thought.

Considering how overworked the police were with the rising number of villains popping up across the country, he honestly wouldn't be surprised if that was exactly what they did.

The Pro Heroes were good at defeating and capturing villains. There were just about enough of them to manage the current levels of villainy across the country, and keep the peace. But they didn't process the villains though after their capture, nor did they investigate their crimes, prosecute them, or run the prisons that held them. No, that was all down to the police and the civil service, just as it was up to the hospitals to look after the defeated villains, injured heroes, and the civilians that had been hurt either by the villains or in the collateral damage that followed the villains' defeat.

They were all overworked and underfunded.

Something would have to give, and unfortunately for Jason Grace, he would likely be one of the unfortunate few that fell between the gaps in the system.

Letting out another sigh, he closed his tablet and entered Jason's room.

It was time to discharge his patient into police custody.

What happened to him after that?

He honestly didn't know.

( - )

(With Jason)

Something was happening.

The doctor had discharged him, but he hadn't looked happy about it.

The nurse that had been looking after him had sent him a sad look at the news, but hadn't said anything besides saying goodbye and wishing him luck.

They had looked at him like he was going to die.

After giving him time to shower and some fresh clothes to change into; grey joggers a white t-shirt and a tracksuit - his boots were still serviceable enough to wear -, they had then walked him out of the building.

Sticking his hands into his pockets as some orderlies escorted him to the hospital reception, Jason couldn't help but look at some of the patients and staff they passed. One of the people he passed was covered in fur, another had horns, while a third looked like she was made out of crystal.

Their appearances surprised him, but for some reason they didn't shock him.

Mentally, he knew they looked unusual. They didn't look human. But at the same time he couldn't find any animosity in himself towards that, or any revulsion. He didn't feel at all surprised or perturbed at their appearances.

It was almost like he was used to seeing people as unusual as this, like he had been inoculated to the bizarre.

Pushing that odd thought away, Jason re-focused his attention as they made it to the hospital reception.

There were three uniformed men waiting for him, one of whom was covered in spines like a human cactus. All three of the men were armed. They had guns holstered at their hips, and what looked like a can of mace, some high tech handcuffs and extendable night sticks on their belts.

Cops.

He knew exactly who these men were, even if the uniform itself wasn't familiar.

Which of course begged the question of why they were here, and more importantly, why they looked up as the orderlies walked him over to them?

Thankfully none of the men went for their guns, but he did see them tense as he approached, their eyes narrowing as he looked him up and down.

"Jason Grace?" One of the officers asked, a stiff smile spreading across his face.

"Yes," Jason replied hesitantly.

"My name is Officer Watanabe, if you would come with us, we can get you settled while we find out what to do with you." Watanabe smiled, his tone full of forced friendliness, as he gestured for Jason to come with him.

"And where are we going?" Jason asked suspiciously.

He didn't like this.

He did not like the way the police officers were looking at him; like he was a snake that could bite them at any moment.

The orderlies looked similarly uncomfortable and tense.

"You're an illegal alien in this country, and until we can sort out just where you come from, you're going to need to come with us." Watanabe replied, his voice hardening, and his hand absentmindedly drifting down to rest on his belt. His fellow officers did the same.

"And what if I don't want to go with you?" Jason replied, tensing.

The orderlies were backing off now, and the other patients in the waiting room were starting to pay attention.

The atmosphere was thick with anticipation.

"I'm afraid you don't have a choice in the matter." Watanabe said bluntly, his hand now resting on his gun. He hadn't drawn it yet, but his intentions were obvious. "Now come along quietly, and we'll get this all sorted out."

"Am I under arrest?" He asked, his voice hard, and his hands clenched into fists.

He didn't want to fight, or for things to escalate.

But at the same time he didn't feel comfortable going with the officers either.

None of it felt right.

He didn't have authority problems. If anything, he was used to following orders.

At the same time, following the order of these men didn't feel right at all.

"No, there is no arrest warrant currently outstanding for you. But I am afraid you are being detained for the moment while we sort out your identity and country of origin." Watanabe retorted, popping the latch on his holster.

"And if I don't want to come with you?" Jason asked, his hands clenched into fists. His gaze flicked down to the guns at the men's hips. For some reason, the thought of being shot at didn't bother him as much as it should.

He didn't feel any fear at defying the men in front of him. Nor did he feel at all threatened, even when they were carrying guns.

"You don't want to do this," Watanabe warned. He wasn't smiling anymore. "There will be legal ramifications if you resist, and formal charges will be brought against you, especially if you use your Quirk; you might be an outsider but the strict laws restricting Quirk usage in this country still apply."

The officer's gun was half drawn now, and the tension in the room was almost unbearable as civilians backed off to the edges of the room, or fled to an adjoining room.

It was like he was in a Mexican stand-off, only unlike the other party, he was unarmed.

Glancing at his surroundings, he felt his heartbeat slow and his growing temper wane as he saw the fear and nervousness on the faces of those around him.

He didn't want to get detained.

But nor did he want to endanger innocent civilians.

"Okay," Jason said after a few moments of tense silence. "I'll come with you."

The three officers relaxed slightly at his words, the tension bleeding out of them.

"Thank you, now if you will follow me, we can try and get this sorted out as quickly as we can." Watanabe said, once again forcing a smile as he gestured for Jason to follow him.

Sending the waiting civilians another look, he felt his heart clench at their fear.

"Fine," Jason muttered, finally moving to obey. His feet felt heavy, and he could feel a fiery anger brewing within his chest as a part of him roared its objection to his decision.

Pushing down that feeling, Jason closed his eyes as he stepped into the light, the sun shining down upon him and almost blinding him.

He could once again hear the dull roar of the city and the beeping of cars.

Looking up, he saw a police van waiting for him, in front of which two armed officers wearing dark blue flak jackets and visored helmets stood, with guns holstered at their sides.

Letting out a sigh, Jason followed Watanabe's orders as he moved to get into the back of the van.

It seemed he was now under arrest.

Or for the moment at least.

Pausing at that thought, Jason rested his foot on the edge of the open van and looked at the impatient looking Watanabe.

"Can you get word out to someone about where I am going, and ask for them to come see me?" Jason asked, not moving from his spot as he locked eyes with Watanabe, giving him what he liked to call 'the wolf stare'.

Twitching under his gaze, Watanabe broke eye contact first. "Sure, whatever, who is it?"

"It's the Pro Hero, Mirko." Jason replied, a slight smile spread across his face as he saw the shock on Watanabe's face.
