Prologue - The Boy and his Demons

He felt it in the air; long before he ever reached the place, he knew there was something wrong. The entire police building was alight with activity, throngs of officers moving to and fro with a sort of fervor that escaped him. It all felt hurried, frantic, and utterly panicked. As if All Might himself had fallen, and now they were left to pick up the pieces.

Tsukauchi Naomasa had seen this before. A villain had gone out of control once, his Quirk somehow allowing him to destabilize the holding cell's foundation enough to free some others. All of that turned into a shitshow that forced several heroes to come and stop the escaped villains from taking over the station.

This was similar, but different, in a way. Officers were still frantic, the place still seemed buslting as they moved to complete some task, yet all of it looked contained. Contained enough for himself to be called in to question someone in a recent villain attack.

Though, the detective knew from experience that things could be way different from how they seemed.

Still, he had a job, and flashing his badge at some jittery members as he walked by served to get to that started. They nodded in recognition, faces flashing with a form of relief that was clearly palpable. Just another thing that set his hackles arise.

"Detective!" A man walked up to him, his eyes large and slited. A mutation Quirk, he added, mentally wondering the applications. "I'm glad you're here. We're honestly not sure how to handle this, and calling All Might or any other hero felt… wrong."

Tsukauchi's face twisted into a frown. "Wrong? I was told to come in to question someone; I had assumed they were the villain in yesterday's robbery."

"You're… not wrong." The man paused, hesitating before a little reluctance peeked through. "They were involved in the previous robbery, and subsequent murders, but… it's more apt to call them the victim."

The detective's features curled a bit, unsure of what to think on that. Yesterday had been a robbery gone horribly wrong, and he had only heard of some type of monochrome bubble as well as trapped innocents. A failure on multiple inconsistent reports from heroes as well as the ineptitude of corresponding first responders.

There was a time when he had believed that leaving All Might to solve the problems of the world was the answer. That time left him the more he interacted with criminals. The more he found that almost everyone had something they were hiding.

And as much as he disliked it, sometimes a lie is better than the truth.

So, he was escorted down the halls of the building into the interrogation cells. The place was as cold and harsh as he last left it; a sort of small square cutout of the world that was made to hold criminals, murderers, rapists, and all types of scum that the world naturally nurtured.

However, looking through the one-way glass, Tsukauchi found none of those. Instead he found a boy no older than five or six, sitting down in the same chair that held monsters in human skin.

A boy with white, almost pale skin sat there shivering. Messy, dark green hair matted his head, trembling along with him, and the large, green eyes the boy had were dull. Shock was setting in, the detective noted; they were fairly obvious signs that he had seen plenty of times.

The boy twitched in the empty room, his eyes looking up to the glass window to stare right into the detective's eyes. It was almost as if he could see them through the shaded glass.

Tsukauchi's breath hitched and hands trembled minutely. Almost in slow motion, he turned to the officer leading him here. "What is going on? Why is there a child inside that room?"

"That…" the officer was pensive, apologetic. "The boy pleaded to be put in the most secure location we had."

"And you just did as he asked?" Tsukauchi's Quirk registered the man as being truthful. There were a great many things that could deceive a similar Polygraph Quirk, but his Lie Detector was in a league of its own.

He knew lies. Knew them like he knew the back of his hand, and the fact that the officer wasn't lying was indicative that something was wrong.

"It- it wasn't my order. I'm- just… here." The officer was clearly put off by even his own orders, and his hands slid a couple pages over to the detective.

Idly, Tsukauchi took the papers, frowning as he read over the information. More specifically, the part where it listed the boy's… Quirks. The fact that multiple distinct powers existed within one person was impossible.

His friend had only told him of the one such outlier, but a six-year old boy wasn't them. Now though, now he had to wonder why the boy's originally recorded Quirk had been erased by multiple others.

"Why does it say that he used to have exotic energy-kinesis, but suddenly have…" he frowned at the more technical names of all of them. They were horrifying in a way he never knew a kid could be. "These? What happened?"

The officer stuttered to answer, his voice meek. "We- we don't know. The Quirk assessments of the boy discovered that he could sense and partially interact with some form of energy broadcast, but for some reason, none of the equipment could pick up on it. His… new Quirks were seen in the robbery yesterday."

All true, the detective noted. However, all these Quirks being used in the high-stress situation of a robbery, and probably having trouble controlling all his new powers was a piece to the puzzle that was slowly coming undone.

If those Quirks had been used… Tsukauchi could see how things turned out the way they did.

"Where's the child's parent or guardian?" He asked, flipping through the pages of information that was proposed to be his new Quirks.

"His mother is currently being sedated in the Musutafu Emergency room criminal holding beds. She apparently got heavily injured when the boy tried to stop the robbers, and he promptly went to saving her… along with augmenting her. Woof." Tsukauchi turned to find the police chief, Kenji Tsuragamae, looking at him with tired eyes. If those eyes weren't on the head of a beagle, then the detective would say they were much more depressing than they actually looked.

The beagle headed man barked over to the silent officer next to the detective. "Woof. You're free to go back to your station, Officer Nichijo. We can handle it from here."

Tsukauchi waited till the man had bowed and left, eyeing the room with the boy again. The child had gone back to staring off into space, flinching every once in awhile. "Can you finally tell me what's going on? I think you've left out quite a bit of information on those background sheets provided."

"It's necessary precaution. Recovery Girl specifically requested for this, and even All Might is sponsoring the child for therapy, if needed. Woof."

The detective's eyes widened at the big time names being thrown around. Sure the child had powerful abilities, and his situation was rather… odd to say the least. However, for those two heroes to get involved, something else must have been going on.

"What happened at that robbery?" There was no more cause for beating around the bush now.

The chief sighed. "I cannot say most of it, but the boy used his new Quirks to incapacitate, to an extreme degree, both the villains and heroes that went to save him. Woof… Not only that, he basically walked out of there without any officer moving to stop him. They later informed us that the boy had a mind controlling Quirk along with the rest that were previously seen. Woof."

Tsukauchi's eyebrows shot past any reasonable height. Everything said was as truthful as the chief could be, and some fanciful story about a child beating heroes and villains before running off was just a little too much to think about. He almost believed that his Quirk was under some nullification ability.

"Then, why is he here? With those Quirks, he'd be able to run if he wanted to."

"That," the chief stressed, "Is what you're here for, and to see if the sponsorships given by each hero need extra consulting."

There it was. His job was finally making sense. A boy with Quirks that each were extremely powerful by themselves, the odd coincidences that surrounded the situation, and why he had to interrogate the boy. It all bled together to make the picture clear to him. The mind controlling Quirk was just the confounding variable that needed to be verified, especially in this situation.

He paused to press the button that linked their room's intercoms. "Hello, can you hear me?"

The boy jumped as expected, head dancing around till it fell back to the glass, his eyes somehow finding something. A tentative nod was all the detective needed to continue.

"My name is Tsukauchi Naomasa, I'm part of the police force of Musutafu. Is there anything you want, or that we can accommodate you with before we begin?"

The green-haired child nodded, trembling. "W-where's my mommy?"

"She's safe." Tsukauchi said.

"N-no, we- I didn't finish." The boy stuttered. "Her-" he looked up as if searching his head for the answer. "Adder-nail glands are making too much… stuff. We- I need to help her."

The detective cocked his head at the broken speech. There were small lies whenever he switched between plural and singular tenses, but they weren't making the whole message false.

"Don't worry." He said, drawing the boy's attention again. "We'll make sure to keep her safe until we finish, and then you'll have our full cooperation."

Tsukauchi felt a little sick talking to a child like this. His words weren't lies, but keeping a boy so young locked in a cold, steel room was pushing all his buttons. At least, as he turned to the police chief, he found that the beagle-headed man was already telling someone to keep an eye on the boy's augmented mother.

Feeling a bit in a hurry himself, he quickly moved on. "I'm going to ask you some questions, but if you don't want to answer, then you don't need to answer, alright… good, now, can you tell me why you turned yourself in?"

"I- I want to be a hero. B- but we- I did something bad."

The detective frowned. Everything was true, but again, the was a lie when the boy switched between 'we' and 'I'. "Could it be someone is forcing you to do this?"

A clear shake of denial was all he got. It was resolute, without any of the previous jittery tension. "No, they-" he pointed to his head. "They're up here. Nine of them. Th- they tell me things... I don't think they are nice people."

Again, the boy told the truth, and Tsukauchi mouthed schizophrenia to the chief, wondering a bit on the child's new Quirk. Perhaps it was something that changed Quirks based on the personality of the controller? It fit a theme for a single Quirk, if a very loose one.

Still, he had something that would protect the child against some charges. The notions of All Might's sponsorship suddenly gaining a bit of ground. All in all, the couple questions he asked had answered almost everything he needed.

Now, though, he had to ask the question at the tip of everyone's minds. "Have you used your… mind controlling Quirk on All Might or Recovery Girl?"

The boy went as pale as a sheet, and the detective idly noticed the smattering of frecles on the youth's face. "N- no! We- I used it by mistake first, but I just talked to them!"

Another truth, to his utter relief. The breath he had been holding was released, and now he just had to relegate what minor slap on the wrist the kid would get to someone responsible.

He had caused damage, sure. His Quirks were definitely deadly, but the fact that the only deaths were those by the hands of robbers also worked in the kid's favor. Only the mental instability was a cause for concern. However, with the support of Japan's number one hero as well as Recovery Girl, the boy would hopefully fix the presented problems.

Tsukauchi settled away from the tense atmosphere. The kid was still trembling, but the detective wanted to ease some of the presented worries. "Don't worry kid, you're not in trouble. In fact, I want to say a good job for helping stop those villains."

He didn't mention the fact that unlicensed Quirk use was illegal. It wasn't the whole truth, but neither was it a lie. This was a delicate situation, after all. Calm deescalation was needed.

"Now, what was that about wanting to be a hero?"

It was instant. The moment the words left his mouth, the boy clammed up, shaking in his seat and face boring into the floor. Tsukauchi almost wondered where he went wrong before the boy spoke in small, trembling tones.

"I- I don't know if I can be a hero anymore."

The detective froze where he stood. Somewhere beside him he heard the police chief barking into his phone, ordering men to move elsewhere. An innocent boy was proven as such, and they needed them out patrolling once more.

However, Tsukauchi never moved. All he did was stare at the trembling boy in a room never meant for him. Sometimes he hated it when he heard the truth. Truths were things that rarely ever were something happy.

Because, even if he only knew the boy for a couple of minutes, Izuku Midoriya deserved for those last words to be a lie.

Because I wanted to write a BNHA fanfic, and the best I could come up with that seemed cool and not done (as much) was an Quirk Izuku. However, there's a twist that I made semi-coincide with things. It's explained a bit, but for those of you who have no idea what happened, Izuku just hijacked a couple shards with his Quirk, but in doing so the shards found him, sending enough information along with their recent host's personality to recreate their powers as sort of Quirks. It's iffy at best, but works in a way.

For those of you who have no idea what that means, and even I'm having a little doubts on my explanation, then just know that Izuku gained a couple of powers from the worst of villains for the best of reasons. Of course, like all good things, there are drawbacks. Some of which as plain to see, and some that are sprinkled through this prologue.

Now, do you need to know either Worm or My Hero Academia before reading this? No. Though, knowing a bit about both could make it more enjoyable. Or less, who am I to know.

If you still have questions, which is entirely possible, I can try to fix things as I go, and address them in my next Author's note.

As always, Enjoy!
