Before we get started with this chapter, I just want to give a big thanks to everyone who's read the story and provided feedback. One of my biggest concerns with going into this story was that this was a crossover that not many people would want to see, but I was pleasantly surprised with the responses I've gotten so far. I will be covering any questions asked in reviews at the end of the chapter.

Shoutout to Zephyr47, Finalcool720, Haxorus Knight, IDK, hcbnc, OneYuTriSlayers, Wizardwolf 1020, FlygonNick, and Gamelover41592 for the reviews.

Without further ado, let's dive right in.

It had been twenty-four hours since the unknown teenager had been personally delivered to the hospital by All Might for emergency treatment. The cuts and bruises were easy enough to treat, but the patient was dangerously dehydrated and exhausted. The doctors had been amazed enough that the boy was still alive, it seemed like he had been going on fumes for days before he was rescued by the Number One Hero.

Currently, he was resting in a hospital bed with an IV attached to his arm to get him some much needed fluids and nutrients. The doctors had been unable to find any sort of ID or other forms of identification on his clothing that they had to remove to treat him and running his face through the police's database had turned up nothing so far.

This is what Tsukauchi Naomasa and Yagi Toshinori were currently discussing in one of the private rooms close to the unidentified patient's hospital room. Thankfully, the staff were under the impression that it was All Might in that room and the staff had been given explicit instructions not to enter without knocking.

"I'm assuming you didn't find anyone by the names he was muttering either? Doctors managed to pick out a couple, but most of it couldn't be made out." Yagi was currently sipping on some hot tea, hoping the boy would wake up soon. Aside from wanting to get some answers about what caused his appearance and state, he wanted to make sure that the boy was okay.

"Unfortunately, nothing so far, we couldn't find anyone with the name Riku or Kairi in the database either. And without knowing what his Quirk is, we can't run a search through the Quirk registry to identify him either. It's like he appeared out of thin air." Tsukauchi ran a hand through his hair, reviewing the case notes so far, of which there was barely anything.

It was a case that was baffling the police, but thankfully the media hadn't gotten a hold of it yet. Aside from Young Midoriya, there had only been one other witness nearby when the incident happened and they agreed to not say anything about it. The young man certainly wouldn't need the media hounding him once he recovered about who he was.

"I think he might have Tsukauchi , Young Midoriya saw him seconds before I did, but we both saw him appear in the air, wrapped in what appeared to be light. I'm not sure if someone used a Warp Quirk to send him there, but given the condition he was in when I found him, someone might have been trying to dispose of him. Though, given how close he was put to the shoreline, it's doubtful since they could've easily dropped him in the middle of the ocean and leave us none the wiser."

The detective sighed at that, knowing that his friend and colleague was correct in his assessment, there were too many factors that weren't adding up about this. "Well, he was mumbling in Japanese at least while the doctors were treating him, so unless he's bilingual, we know he's from somewhere in Japan, Asia at worst should it come to that. But the fact that him or the other individuals he muttered aren't coming up in our search is concerning. How do we know that he has family looking for him? Or anyone is looking for him for that matter?"

"I'm sure that someone is looking for him, it's only a matter of finding out who and where they are. Right now, all we can do is wait for him to awaken." The pro hero smiled as he had no doubt about the boy's recovering, with the detective nodding and his own smile forming.

The quiet that followed that lasted for all of ten seconds.

"WHERE AM I?!" The voice was loud enough to be heard across several rooms in the hospital, with the pair immediately hopping out of their chairs. All Might immediately transformed into his muscular form as Tsukauchi ran out the door first and towards the room of the patient, fearing the worst for his condition.

When the detective slid the door open, the spiky haired boy as currently sitting up in his bed, dripping with sweat as his expression screamed confusion and panic. Other than that, the boy looked like he was healing up nicely, his cuts and bruises were barely noticeable after the healing Quirks that were used and he looked rested enough.

The detective cleared his throat a bit to get the boy's attention, trying to put him at ease. "It's okay kid, you're just in the hospital. You were found in pretty bad condition by All Might, but he got you here right away."

The boy looked at the detective and took a couple of deep breaths, trying to compose himself. "Right, but um...who's All Mi-"

"I am here, to check on the patient!" All Might entered the room and closed the door shut behind him, ignoring the protests of some of the other patients who wanted his autograph now that he had stepped outside. He knew the doctors would be coming along shortly and hopefully the small crowd would disperse by then.

"Young man, I am quite relieved to see that you're on your way to making a full recovery. You gave everyone quite the scare given how injured you were when we found you." All Might had that wide smile on his face as he spoke to the young man, preparing to give either an autograph or a picture. Most people tended to ask for one when they had been saved by him.

"Yeah, I'm feeling a lot better now, but who are you?" The question was innocent enough, the two veterans couldn't find any hidden intent in them, but it just led the way to more questions. There wasn't anyone on the planet who hadn't heard of the Symbol of Peace, the Number One Hero All Might. Before the pro hero could inquire about it further, Naomasa spoke up first.

"This is All Might, the pro hero who rescued you. Now, I just want to ask a few questions while we wait for the doctors to come and check on you now that you're awake. You think you're up for that?" The boy shrugged, before nodding, laying his head back down on the hospital bed after looking at his hand intently for a few seconds. It almost seemed like he had been expecting something to happen, his Quirk maybe? The detective took out his notepad and a pen, taking a seat near the patient's bed.

"Thank you, I'm Detective Naomasa. Do you remember your name?" He wanted to ask a few basic questions, first to see if the patient was suffering from some form of amnesia. If he wasn't, then some basic information that would hopefully help their search to find this boy's family or point of origin.

"Yeah, I'm Sora...Haruki." He clearly wasn't used to using his family name, because the boy took several seconds in stating it. Did he have trouble remembering it or did he just not use it very often? Either one was concerning.

"Thank you Haruki-kun, it's nice to meet you. Next question,how old are you?"

"15...though, it might be 16 soon, I've kinda lost track of time lately. How close is March 28th?" A birth date, that would help immensely. The detective chuckled a bit at the question, trying to ease his own worry. Sora not knowing what day it was certainly raised a lot of red flags. Had he been held captive by a villain for long enough that he lost track of the time?

"We're still over half a year away from that date. So no worries there. Now, my next question for you, where are you from?" The reaction to that question was concerning to say the least, Sora bit his lip for a few seconds, as though trying to come up with an answer. Was he trying to hide something or could he not remember? Thankfully, his Quirk would help with that. There was a reason he had the nickname True Man among the police force, his Quirk allowed him to tell if a person was lying or not.

"Destiny Islands." His Quirk registered that as true as he jotted it down with his other notes, though that location didn't sound familiar. It was likely a small island near Japan and the locals just called it that. Should be easy enough to sort out at the station. The detective didn't notice the concerned expression that Sora made after he gave the name of where he was from.

"My last question for you for the time being, what is your Quirk?" In the worst case scenario where Sora Haruki didn't exist in any police records, there would have to be something in the Quirk registry. The answer that Sora ended up giving however, set off multiple warnings in both Naomasa's and Toshinori's minds.

"What's a Quirk? I've never heard of that before." The worst part is, the answer came back as another truth. In this day and age, while not hearing of All Might was incredibly unlikely, it was still feasible. But not knowing about Quirks? That was an impossibility, given only 20% of the world's population was Quirkless and most people developed there's by the age of four, five at the latest. There was something seriously amiss here, but before Naomasa could question it further, All Might stepped in.

"A Quirk is like a unique power that only you have! For example, another pro hero is capable of creating and controlling flames, adjusting the temperature at will. Some can change their size, the list goes on!" The Number One Hero certainly hoped that would jog the young man's memory. Or at the very least, see if that would trigger anything.

Sora sighed quietly to himself, the sound barely being heard by the two adults in the room. "I...I'm not really supposed to use my power unless I need to defend myself." At that response, the detective could immediately tell the boy was lying, writing it down with his other notes. Was it possible that he was bullied for his Quirk? Or had he been sworn to secrecy about it? Before he could ask Sora about it, All Might laughed a bit.

"Well, that is a fine practice Young Haruki. However, we want to help you get home and while the information you've provided will help in that regard, knowing what your Quirk is will certainly help even more! It can be our little secret that you showed us~" Sora looked between All Might and the detective, before smiling a bit. Thank goodness that All Might knew how to win someone over, it made stuff like this a lot simpler.

"Alright!" The boy sounded excited now, a far cry from his reluctance just a few seconds ago, outstretching his hand as he seemed to focus. There was a small flash of light as something appeared in Sora's hand. The object appeared to be key shaped in nature, though it was unlike any key they had ever seen and it was quite large, a weapon perhaps? In addition, the weapon seemed to be made entirely of light. Could this boys Quirk allow him to make constructs out of light? If so, it was certainly a potent Quirk, which would beg the question why he lied about being allowed to use it.

Sora's expression though was puzzled as he moved his hand slowly, allowing himself to examine the construct. "Weird, this is the first time it's ever looked like this." After another thirty seconds or so, he let the weapon dissipate to nothing. His comment wasn't missed by the two grown ups, who shared a glance. They certainly had more questions now, but hopefully with what they had learned so far, they would be able to get some answers.

"Thank you for showing us that Haruki-kun, I know that probably wasn't easy for you. We'll have some more questions for you later, but for now we're going to see if we can find your guardian so we can let them know what happened. In the meantime, try to get some more rest, I'm sure the Doctors will have plenty of questions for you as well."

Sora's eyes widened for a brief moment at the word guardian, before he smiled at the two adults. "Thanks, I appreciate it."

The two adults nodded and left the room quietly as a nurse and doctor quickly went into the room to do some examinations and ensure that the patient was healing nicely, with Tsukauchi having given Sora's name to the doctor on their way out so they could have a name to update their paperwork with.

"So Tsukauchi, what did you make of Young Haruki?" All Might trusted his long time friend when it came to determining someone's character and while he had found Sora to be a nice kid, there were too many oddities surrounding him.

"Well, aside from lying about not being able to use his Quirk, he seems trustworthy enough, but something's odd. The kid doesn't seem to have long term memory loss since he can clearly remember his birthday and he mentioned that his construct looked different than it normally does. In addition to that, he didn't know who you were."

All Might chuckled a bit at that as the two reentered the room they had been occupying before. "Well, it's not like everyone has to know who I am! Though it is odd, the way he smiled reminded me a lot of myself."

"Right, the kid seemed to try to be as positive as possible about what's going on, though there are clearly cracks. Maybe some sort of recent emotional trauma? But what really got me was when he said he didn't know what a Quirk was." Tsukauchi's tone turned serious as All Might turned back into his normal form, not wanting to waste time in his muscular form if he didn't have to.

"That concerned me as well, in our current society, it's impossible not to know about Quirks. Even if he was extremely isolated in his home and community, he would've needed to be told about Quirks once his own developed. Something isn't adding up about all this."

Tsukauchi sighed and nodded in agreement. "On that, we're agreed. I'm gonna take this info down to the station, see if I can't find anything on Sora now that we have some more of his personal information. Should only be a few hours. Once the doctors are done looking the kid over, see if you can't try and find out more from him."

Yagi nodded as he picked up his cup, noticing that the tea was now cold, sitting it back down. "Right, hopefully Young Haruki will remember something about where he was or who had done that to him. I'll wait to see what you can find in your search before I question him though."

It had been about four hours since Detective Naomasa and All Might had visited Sora in his hospital room, with the young man having been left alone for about two hours now. The doctors had looked him over and told him that his recovery was going well and at this rate, they should only need to keep him for a couple more days for observation. The first thing he had asked for once the examination was over was some food, which Sora had scarfed down, despite the subpar taste. He had definitely gotten too used to making his own high quality food at the Bistro in Twilight Town.

Once he had finished eating, the doctors had turned the lights off and closed the blinds, wanting Sora to try and get some rest, but the teen could do anything except rest. The last two hours had been spent with him reflecting, apparently his arrival in this world...no, worldline, he had to keep reminding himself there was a difference. Anyway, his arrival here had given people a scare, though falling out of the sky wasn't really anything new for him. As soon as he arrived though, this hero All Might had managed to save him almost right away.

"He was definitely something, muscles larger than Herc and one of the most reassuring people I've ever met." He thought about what that voice had told him before he blacked out, that this was a world of heroes. If all the heroes here were like All Might, then this worldline was definitely in good hands.

Sora facepalmed as he thought about how he had told them that he was from Destiny Islands, the voice of Donald ringing in his ears about the World Order. He had always been a bit bad at concealing that and with everything that had happened, it slipped his mind until it was too late. He only hoped that either there were a series of islands on this world called the Destiny Islands or that they wouldn't ask too many questions. The young man didn't really enjoy hiding the truth, but he had been reminded enough to know better. Did the same rules even apply when it came to worldlines, especially ones with no keyblade wielders to speak of?

Sora looked at his hand and clenched it a little, remembering what had happened when he had tried to summon his Keyblade. It had looked different, made entirely of light and it had felt...different. When All Might had told him what a Quirk was, Sora had thought that Quirks were how they described Keyblade Wielders here, but it was clearly something different. Something he should have realized right away given that the voice had said there were no Keyblade Wielders in this world.

Was what was left of his power converted into a Quirk? At the very least, his Quirk seemed to be based on light, which was a positive. He'd need to figure out his new limitations and capabilities once he was out of the hospital. He was used to losing is power before, but at least then he was still operating under the same rules. This worldline was something entirely new and he had no idea how his power worked now.

The sooner he figured that out, the sooner he could start working on getting back to his own worldline. He knew that it'd take time, but he'd do everything he could to get back home quickly. Maybe teaming up with these heroes would help him find answers? He was certainly used to fighting and performing heroics thanks to his numerous adventures. He just needed to figure out where his strength was right now.

Opening his hand again, he tried to focus on summoning his Keyblade, but instead of getting the weapon this time, a small orb of light floated above his palm. He hadn't done anything different from last time, why was it different? After a few seconds, the orb of light vanished, causing Sora to groan in frustration.

"Urgh, did my power really get diminished that much? It's been bad before, but never like this!" He knew his powers weren't going to be the same when he got to this world, but to this extent? He could at least try to recreate some of his physical skills since he could still make something resembling the Keyblade, but anything involving magic was going to need a visit to the drawing board.

Before his train of thought could continue any further, there was a soft knock on the door. "Young Haruki, are you awake?" Was that All Might? Did they manage to find something already?

"Yeah, I'm up. Can't really sleep." His response was met with the door opening and All Might stepping inside, the smile from before still on his face. Though it seemed a bit different compared to before, a seriousness that Sora could recognize. Did they know?

"Well if you're feeling up to it, I have some more questions for you. Let's start with who you are, Sora Haruki."

And that's all for this chapter!

Things are moving along quickly now, with All Might and Detective Tsukauchi figuring out that's something is off about Sora's origins and with Sora slowly starting to learn about what the world of heroes is really like, along with his new power. Onto the Q&A.

From Haxorus Knight

While there will be implications of Sora x Kairi in these early chapters, it will not be a main focus once we get to U.A. High proper. Sora has been through quite a lot in his life over the last year and a half, give or take a couple of months, and this will really be the first time he's gotten to really think about everything that's happened to him and his friends. He definitely has feelings for her though and I'm pretty sure if he hadn't vanished at the end of KH3, they would be dating.

From hcbnc and OneYuTriSlayers

Truthfully, I had started coming up with this idea a few weeks before ReMind came out as I started MHA before the new year started. With how ReMind ended though, it just proved to be a slightly better jumpoff point than Sora vanishing at the end of the main game. Just because Sora won against Yozora doesn't mean it was without cost.

From Wizardwolf 1020

Hopefully as I am starting to build up in this chapter, while Sora's Quirk is going to have it's drawbacks, it will become a very potent ability once he understands it better. I do have a plan for how his Quirk will be growing and evolving throughout the story and while it's going to be a long time before it pays off, we'll get there. As for his Quirk being temporarily disabled or stolen/lost, have to stay mum on that for spoilers. And hopefully this chapter helped address your concerns with them not believing he's from another worldline, the cast of My Hero Academia is pretty intelligent and given the things that've happened in their world as a result of Quirks, Sora's story may not seem so crazy to them. Plus Sora is an atrocious liar, pretty sure the World Order would've been busted multiple times if not for Donald.

That's all the questions or topics from the reviews that I wanted to address, but there is one thing I do want to state before we close this chapter off. As of right now, there are no plans for any other characters from the Kingdom Hearts universe to crossover, at least for the foreseeable future. There will be references and mentions to them and events that happened, but I feel bringing in any other characters in the immediate future would hurt one of the ideas that I want to tell with this fic.

As for an update schedule, at the moment I don't have one planned, but I am working on getting a backlog of chapters done so that I can at least ensure a weekly update should something happen.

Until next time, take care!
