Chapter Text

Aizawa arrived at the building collapse in a hurry, all heroes available were called in to help with the search party, rescue and rubble clearing. He was working extra late, but since he was in Musutafu and only a few blocks away he came straight away. Swinging off from the still lit lamp post and landing nearby he scanned the scene for any information he could gather just from observing. The dust still filled the air and clung to Aizawa’s clothes, ruble covered everything, from the then building, now foundation, to the other side of the roads surrounding it. He asked the nearest worker on what they need help with to which he then directed him to the south-most pile of rubble, a particularly unstable pile that covered the busiest street. He pulled up his sleeves and got to work, he then asked the people around him for more info, “Does anyone here know why the building collapsed?” he called out to no one in particular.
“It’s not certain but the leading theory is that the building is older and not up to standards, not much else could bend the support beams like that.” A chubby yet muscular worker answered, pointing to a beam that was halfway sticking out of the ruble, bent at a… ‘pretty’ angle. “Overbearing is my guess, too much stress over time bends the beams, though I’m surprised, this shouldn’t have happened since this issue occurs over long periods of time and signs pop up long before the collapse is even close to happening. Pipes creaking, leakage, mold, concrete cracking, etc.”
“Haven’t I told you already? The building was built only thirty years ago, its not old, far from it.” An older man replies, probably a neighbor.
“Oh yeah, then how do you explain this?”
“I don’t know, but it sure ain’t that!”
“Gentlemen, please, calm down, there are people to save and work to do.” Aizawa said, putting an end to the bickering, the last thing people in a building collapse need is arguing or worse yet, a fight.
Aizawa slaved away at the rocks, hours had passed and the sun started to rise, feeling balls of sweat run down his back. He’d say it’s worth it if any progress was made but they’ve only cleared out a quarter of the road and the biggest pile, only enough for a motorcycle to pass and volunteers to safely bring water and food for everyone working to take a break and cool off before getting to work again. It was on one such break that, while Aizawa was chugging water, overlooking the scene, he noticed a piece of rubble move on its own. Seeing that someone was about to approach that are he called out a warning, “Hey! Watch out! That area is unstable!” He put the water bottle down, took a nearby danger marker and ran over. Making sure not to get to close himself he set the marker down, as soon as he did the piece of ruble started moving again, this time more intensely and not only it but the ruble around it too. “Back away, it might collapse!”
Everyone listened to the warning and moved back onto the safe ground of the street, watching from afar. However, the ruble didn’t fall or crash further, it…rose? The ruble started lifting…a person? But the ruble would be too heavy, and it’s been hours, no one could survive that; there’s simply not enough oxygen with all the dust. But then how is the ruble still rising? Aizawa squints, trying to look at whatever is underneath the piece of concrete through the dust that’s been kicked up; you’d think the sun would help compared to the darkness, but it just illuminated the dust and blocked his view. The first thing he sees is…an arm? It’s a person after all!
“There’s a survivor, come on!” He called out to the volunteers and first responders to bring first aid and water. He just stepped on the first piece of concrete when the person pulled themselves out of that grave, the ruble fell off and they stood up. It was a teenager, judging by the height and stature of the person; how on earth did a teenager survive this? Even from this distance he could see they were in shock, back hunched, holding himself arms…arm crossed…They lost an arm. But…no blood? Other than the gray and brown dust covering their somewhat shredded clothes head to toe there was no red anywhere to indicate they bled. Aizawa stood there in shock, and so did the others. The teen turned to look at the group staring at him, not showing any sign of actually seeing them. Then, he looked up at the sky, the rising sun’s rays finally shone onto the scene; he reached up as if to touch it and when he did it stunned Aizawa even further. A bunch of light rays dispersed from the teen’s body, he shined like a disco ball, and everyone just stood there, he doesn’t know for how long, maybe even minutes passed until he finally remembered to move. He grabbed a blanket from a still stunned volunteer, rushing over to help the teen who has now lowered his arm and finally started to process what was happening or had happened.
Aizawa finally got close enough to look the teen over, as suspected, they’re missing an arm, injured and cracked all over, a hole where the heart would be, and it looks like their foot is missing, judging by their features they’re male and around 15 years old. However, the odd thing is, is how his injuries look, there’s no flesh or blood it’s…it’s just…crystals. Shards, like glass, except green? They had this shine to them, it wasn’t skin, it wasn’t flesh nor bone, just crystal. Aizawa is no expert, but it looked like…emeralds?
“Thank you, that’s not necessary.” The teen said, pulling off the blanket while also bringing Aizawa back to reality.
“Please kid, you could freeze.” Aizawa negotiated.
“Couldn’t even if I wanted to, thanks to my quirk.” They answered while also gesturing to their body and missing arm.
“Ah, I see…What even is your quirk?” Aizawa couldn’t hide his confusion. “And doesn’t it hurt, come on, let’s get you to first aid.”
“Again, thank you but that’s not necessary. I can’t feel pain; also, the medics couldn’t do anything even if they tried.” The teen gave a flat line smile. “Mind helping me go sit over there, I’m kind of missing a foot.”
And Aizawa did just that, his first instinct was to sit the teen down near the medics, but the teen refused and told him to bring him to the other side of the ruble, ‘where the sun was’. “All right kid, I know you’re injured but I’m expecting an explanation at the very least. Start with the basics: your name, quirk, last thing you remember, so on. I’ll go first, I’m Shouta Aizawa, a pro hero, hero name: Eraserhead, I can temporarily cancel quirks by looking at people.” They sat down on the pavement, overlooking the collapsed building.
“Right, my name is…” The teen paused. “I don’t remember who I am.” He sighed. “Don’t worry it’s not a concussion. It’s…something else; wish I knew what.”
“Kid, I asked for answers not riddles.” He sighed, feeling a headache coming in, staying up all night and dealing with a problematic kid isn’t a good combination.
“Yeah well, I’m experiencing memory loss. Hold on…”
“I’m waiting…”
“I know that I live here- well, used to. I went to school here too. I was quirkless before, I remember that! My quirk came in late, very late, don’t know when, but my body slowly turned into crystals, replacing all of my organs and tissue…That’s all I can remember about my life story…But my quirk, I remember more about that. Since my body is crystal and all my organs were replaced I miss many of my functions, I can’t eat nor drink so I don’t feel hunger or thirst, I don’t need to breathe, I don’t sweat, don’t feel pain, don’t feel warmth or cold, etc. Last thing I remember is…going to school, it was a Monday.”
“Do you know how old you are?”
“Yes!” He said excitedly, happy to know an answer to a question, “I’m fourteen! I remember celebrating my birthday…there was, a woman…but not my mother.”
“Are you sure?”
“Yes, I can’t make out her features, she’s fuzzy, but I know she’s not my mother; I think she’s blonde? And I’m not blonde.”
“Yeah, you’re emerald.” Aizawa noted, looking at the boy’s mutated hair, like hard cotton candy, shiny and glimmering in the sunlight.
He laughed, “Come on, I know I’m green but-” as he reached to run a hand through his hair he didn’t recognize the feeling nor the length, bringing it in front of his eyes he looked at his hair as if he never saw it before in his life, and considering the situation? Very likely, “I don’t remember this, this is new…It was short and curly before, and…normal, like yours. Well, in the sense that the texture was the same.” He sat there, staring, conflicted.
Aizawa broke him out of his stupor. “I’m guessing you don’t know your family?”
“No, I know my father was absent from the start, but my mother…likely I just forgot her? And if she lived with me well…” He looked at the collapsed building, “She’s dead.” Wow kid? No sadness, how blunt could he be? “Why are you looking at me like that? It’s hard to be sad over someone I don’t remember.” He defended himself.
Aizawa looked at him and hummed a ‘Mmm’ understanding the boy if only a little. “Does your quirk do anything other than rid you of your organs?”
“Well, I’m much stronger than I was before, faster too, despite my weight. I’m also very durable, if you punched me it’d be like hitting a wall except worse. Well, I guess I don’t have to explain that since you did see me walk out of a collapsed building.”
“Yeah, scared the shit out of me if I’m being honest. But you didn’t come out unscathed.”
“Yeah, even diamonds break if you hit them right, well, I’m not as hard as a diamond or at least I don’t think I am. Don’t remember going to get a Mohs scale test, I’d say I’m decently high though, maybe five or six?”
“Think it’s good enough to be a hero?”
“I’d like it if that’s the case.” A small smile crept back onto his face.
“Well, my husband will be here soon to drive me to the station, we’ll drive you too. There, they can identify you, find possible relatives and you’ll be on your merry way.” Aizawa looked at the boy’s features once more, noticing something different. “Hey, your cracks are healed…”
“Hmm? Really? I guess that’s why my instinct was to go into the sun, my quirk probably requires it somehow, huh.”
“Please, and how would that work?” Aizawa pointed out his foolishness.
“I’m literally a walking humanoid crystal yet you don’t believe my quirk might require sunlight in some capacity?” He raised a brow.
“Yes, because you’re ridiculous. Your quirk is way overpowered.”
“Oh yeah? And your quirk? You erase the quirk temporarily? How does that work? Does it affect the quirk cells or genes? Do you need to activate it or is it passively on all the time? If you look-”
“Looking at myself in the mirror doesn’t work, if my gaze is reflected through any object my quirk stops being effective, it’s gotta be the real thing.”
“Okay…you didn’t answer the rest…?”
“Hopefully, I won’t have to.” He muttered under his breath. “My husband’s here, come on.”
“Is your husband any better than you? If not, I think I’d rather walk there.”
“Yeah, he’s much better at dealing with children, though he’s a bit loud so fair warning.”
“Mm, did I forget to mention my hearing is better than normal? Vibrations travel better through solids, and the crystal structure also reverberates sound and makes it louder. I’m not the best with loud noises for that reason”
“Wow, you have a weakness.”
“If you want to call it that. Not like the loud noises hurt, it just overpowers any other quieter sounds.” It was then that they were approached by a long-haired blonde wearing casual clothes.
“Hi Shouta! And hello you! I’m Hizashi Yamada and you are?- Oh, you’re such a cutie! Aizawa, look at him! He’s literally a precious gem- Oh god your arm’s missing!” They looked down at their arm, “Don’t worry, it doesn't hurt.” That had Hizashi speechless and Aizawa couldn’t help but giggle at his husband’s expression.
“Wow, what an…interesting quirk you have. Anyway, let’s get you two to the station, the car is just around the corner, come along.”
The drive was spent with Aizawa filling in Hizashi about everything that happened while the mystery in the backseat just watched the buildings they drove past, though, he must’ve remembered; or at the very least realized something because his mood changed pretty drastically, only responding to Hizashi and Aizawa in short sentences or hums while also having a gloomy look; Aizawa could’ve sworn his shade of green got darker too but that might just be due to the car lighting. Trying to get him to talk a bit more he asks, “Have you lost your memory before?”
“No…this is the first time; it’s kind of terrifying. I don’t even know my name.”
“Don’t worry little listener, your memories will slowly come back to you, it’s what happens in most cases, the biggest step is finding out what your name is and that’s easy enough.”
“Yeah, but what if they don’t come back? Or worse, what if they do and I don’t like what happened.” Complex thoughts and feelings…he doesn’t want to deal with this when he’s tired and half asleep, he’ll let Hizashi deal with this on his own.
“Why do you think that’s the case?”
“Well, I don’t remember anything from before by body started turning crystal, and with the loss of my arm and other bits and pieces I also lost my memory…”
Hizashi raised a brow, “Sorry to say, but I don’t see the correlation.”
“Think about it. Memories are stored in the brain, aka synapses that are built over time. Since my cells don’t allow that structure because they’re…well, crystal; memories must be stored some other way, possibly in the cells themselves, so if I lost a part of my body I’d also lose the memory. It’s possible since, as I said, I don’t remember anything before my quirk developed meaning the memories built up got destroyed along with the structure, and the memories I had in between being half crystal and human are still there because the quirk cells could store them. The only issue is that I don’t understand why I don’t remember my name, that memory should have already integrated into the cells. But the rest makes sense, doesn’t it?”
“It does! Well, we might not know much about your life up until now, but one thing’s for sure: you are a genius!”
“That also means that if we find your arm and other crystal pieces you could regain your memory; if you can heal cracks in the structure you could probably also reattach missing parts.” The boy perked up at this for a moment before going back to his gloomier mood, “If only they weren’t under five feet of ruble.” He muttered.
“Your cells holding memory is likely, you have an innate understanding of how your body and quirk works despite missing most of your memory. I mean, you knew you didn’t have a concussion and needed to go into the sun before you even blinked three times.” Aizawa added.
“Before I blinked once.” Midoriya corrected, “I don’t need to blink.”
“But you did when we talked to you…”
“‘It’s rude to stare’.” The boy quoted no one in particular and Hizashi laughed, “You got me there!”
“Kid, you don’t need to go out of your way to make people comfortable, why force yourself to blink?”
“You say that but trust me, after a minute or so you’d understand why I do it. Humans are innately uncomfortable with being watched, we take it as a sign of aggression; it comes from when we were primates. That’s actually why most animal mutants struggle with keeping eye contact, the primal part of their brain is more pronounced.”
“Huh, the more you know.” Hizashi thought. “Seems like you’re pretty knowledgeable, eh?”
“Well, from what little I know, I have good grades in school and watch informative videos online. But I think the biggest thing is a notebook where I analyze heroes, its numbered thirteen so I guess I’ve been doing it for a while. I don’t just analyze the quirk, but how it’s used and what it affects, theories too; if I find any trivia I also look into it. If I remember correctly the last hero I analyzed was Rogue Phantom, and a piece of trivia I found is that they actually hate falling despite their quirk allowing them to fall without injury. Apparently, falling is a primal fear and that lead me to researching what other things originated from our ancestors.”
“I’m unfamiliar.” Hizashi replied. “But that seems like a useful hobby, thinking of becoming a hero?”
“Yeah.”
“Think you made an analysis of me?”
“You’re a hero too?”
“Yup! Present Mic!” The kid thought for a couple of seconds, “Sorry, not sure, maybe in a previous notebook? It’s likely, I listen to your radio show!”
“Do you remember the rest?” Aizawa asked, curious, “Last half of the twelfth one.”
“So, it ended on the thirteenth one? Unlucky.” Hizashi said. “You and your superstitions.” Aizawa eye rolled.
“What’s wrong with a little superstition?”
“Nothing, but knowing you, if you fall into that rabbit hole you’ll be reading tarot cards every morning to check how the day is going to go then scream when you get ‘death’.”
“I would not!”
“You would.”
“I’m not like that at all!”
“Yes, you are.”
The kid started giggling at their bickering and at this point they only did it to keep him laughing. After a couple of turns though, they stopped, arriving at the station. By the time Aizawa was done with his patrol and collapse report Hizashi was still sitting with the kid while they waited for the officers to identify him and find any relatives. He decided to join them, give the kid some support even if he was tired and really wanted to go home. He’d never admit it, but he’s got a soft spot for kids, he may not know how to deal with them, but they sure are sweet. Actually, since he knows the kid is a sweetheart and hero-hopeful with a lot of potential…why not send a message to Nezu? He won’t pull any strings, but if the kid ever comes to the entrance exam, he’d want Nezu to pay attention to him, give him a better chance. Additionally, it wouldn’t hurt to also have him on some kind of watch, he’s made of gemstones, if a human trafficker got hands on him…Not long after he sent a mail to Nezu, a police officer came, announcing they had good news and bad news. The good news were that the kid’s name is Izuku Midoriya, he’s fourteen; still registered as quirkless though, so the officer gave him a form he could fill out at any time and bring it back to have an easier and quicker time changing his quirk status. Bad news: no living relatives, his former guardian was a woman called Inko Midoriya, which didn’t ring any bells for the kid. However, Inko Midoriya didn’t leave behind a will or document stating any trusted adults who could care for the kid instead, which left Midoriya with the only option of going into the foster system. Going back to Aizawa’s previous train of thought, that’d only make it easier to traffic him…
“Hizashi,” Aizawa called out while trying not to startle Midoriya who has fallen silent once more, “come with me.” Hizashi quirked a brow but followed anyway, they stopped behind a nearby corner, out of sight from prying eyes. Before Aizawa could speak he got a notification, a specifically pitched ‘ting’ that indicated it was important, meaning it came from either Nezu or Tsukauchi, he’s guessing the former. Opening his phone and looking at the email Nezu sent as a reply, Hizashi tried asking him what was going on but Aizawa shushed him, concentrating on the mail. ‘My! The kid sure is interesting, I would love to meet him one day. From his files I see he has no living relatives! You say you’re with him?’ If that wasn’t Nezu implying something Aizawa doesn’t know what is.
“Are you going to explain? Shouta, you’re scaring me.” Hizashi spoke up again.
“Remember how you said you wanted to adopt a couple of days ago?”
“Yeah, you said it’s a big decision, but if I wanted to we could look into it? Why?” Aizawa gave him a look, unsure of what to say, but it seems Hizashi picked up on what’s going on, grabbing him by the shoulder and pretty much shaking him. “Oh- Oh! Are you serious!? Isn’t this too sudden?”
“Yes; but the kid needs someone and Nezu practically commanded us through passive-aggression. Besides, it might be the lack of sleep speaking, but I’ve grown fond of the kid, and it seems like a good idea.” Aizawa looked at the kid from afar, contemplating.
“Yes! Yes, thousand yes! We’re going to be dads!” Hizashi was sold on the idea, almost jumping from excitement. “All right, all right, calm down. First, we need to ask him, he has every right to decline and if he does we won’t push it.” Aizawa warned his husband.
Walking back, the kid- Midoriya, he has to get used to that; looked at them but didn’t say anything further, unsure how to start Aizawa took a deep breath, but Hizashi put and end to whatever he was going to say before he could even get a syllable in. “Listener, Midoriya, what do you think about the idea of us two adopting you?”
Midoriya stood- well, sat; speechless before saying anything, “Well, I’m not opposed to that idea…actually I’d be really happy.”
“That settles it! Come on officer, give us those adoption papers.” Hizashi said almost too enthusiastically. The officer in question stared blankly before registering what had just happened, before heading to the printer in a dazed state.
…
“Well, this is our apartment, it’s not the biggest but the three of us will fit just fine. You’ll be staying in the guestroom though I need to clean it up before you go inside.” Hizashi said as he opened the door for Midoriya who was leaning onto Aizawa for support, being off balance due to his foot...or lack of. He could still walk around since stepping onto the stump didn't hurt but the balance was way off. The entry way wasn’t anything out of the ordinary, it lead to the living room and kitchen if you went straight, and the rooms and bathroom if you turned left. Honestly, the only thing of note was the plain brown cat currently looking at the three entering. “Oh yeah, we have two cats, this is Jennifur.” Jennifur meowed in greeting after which Aizawa scratched it by the ear. “The other one is Catrick, he’s probably around the corner sleeping.” And sure enough, when Midoriya looked around the corner he saw a black cat with white patches, like a panda, sleeping on top of a pillow. “Cat puns?” Midoriya asked, amused.
“Take a guess at who gave them their names.” Aizawa sarcastically said. “I don’t kneow, anything is pawssible with you two. But the names are purrfect fur all I know.”
“Oh no, we really should’ve waited to choose to adopt you.” Aizawa joked while Hizashi snickered behind Midoriya.
“Too bad, you’re stuck with me meow.” Aizawa chuckled at that, he could respect the hustle.
They walked further into the apartment and Hizashi introduced Midoriya to his new home, showing him the layout along with where anything he might need is. Thei apartment was pretty standard, so Aizawa didn’t really need to be there, instead choosing to start wiping the guest room clean of all the dust that accumulated while Aizawa and Hizashi lived here, not using it practically ever. There was one time when Nemuri had stayed over because she got too drunk on New Years but other than that they had no use for the room up until now. He’ll let Hizashi do the rest as he’s currently too tired to care about anything but the bed calling his name from a room over.
…
“Hey, you awake?” Aizawa woke up to a familiar voice, yet it wasn’t Hizashi’s. Opening his eyes he sees Midoriya at the door, “I am now, what’s up?”
“Sorry, Hizashi asked me to wake you up, he says it’s time for dinner.” Finally coming to his senses, Aizawa looks Midoriya over again, his arm has recovered quite a bit, already down to his elbow. He also noticed his baggy, yet intact, clothes, “Hey, you’ve got new clothes.”
“Yup, Hizashi borrowed me some, though they are a bit big. He wants to take me shopping tomorrow.”
“You’re taking the moving pretty well, I kind of expected this to be difficult for you.” Aizawa realized how that might sound, “Sorry, just something I noticed.”
“Well, I said it before, it’s hard to be attached to something I don’t remember. Also, better to get comfortable sooner rather than later, I’ll be living with you two from now on so might as well get used to it, right?”
“Right.” Aizawa couldn’t deny it, he was slightly off put by this. Maybe it’s because he never lost his memories before but from his perspective, Midoriya had a very different point of view from what Aizawa would expect from himself and by proxy other people. He’s happy for the kid, of course, it’ll help him adjust faster and create less issues for them all, but his line of thinking felt foreign. Guess Hollywood affected the way he thought adoptions go, either that or this kid’s odd, well, odder than a kid who’s made of emerald. Right, that reminds him, “So…how will you eat dinner?”
“I won’t, I’ll just be making you company. Hizashi has me analyzing heroes to try and spark my memory since my theory isn’t proven to be fact, there’s still a chance I remember something.”
“Let me guess, he made you analyze him first.”
“Yup!”
“You don’t have to listen to everything he says, y’know?” Aizawa said as they entered the living room that connected to the kitchen, “Yes he does, I’m his dad!”
“Already using the dad card, eh?”
“I don’t mind; it’s fun. His quirk in and of itself is pretty simple, but the way his vocal chords and eardrums mutated to create and withstand such loud sounds is pretty interesting to think about. I don’t have access to an x-ray machine to confirm my theory but I’m guessing that near his vocal chords he either has a bigger space for the vibrations to resonate or modified lungs that create more pressure. I’m thinking more of the latter since a resonance chamber would be constantly active unless muscles moved away, but Hizashi doesn’t have a thicker neck than usual, so I doubt there’s even enough space for all of that. Possibly a wider mouth and nasal passages but again, doesn’t look unusual so I doubt that. So, the more likely case, his lungs being more pressurized; it would allow for both the usual and enhanced volume. His diaphragm and intercostal muscles must be able to expand and contract further and faster, creating a stronger push and ‘boom’ of the air. I’m not so sure about his eardrums but he says he’s always been a little hard of hearing so it’s possible the drum was made less sensitive to vibration.”
“Wow kid, you’ve been working overtime?” Aizawa said impressed, sitting down at the table as Hizashi sets the dinner down. Midoriya sat down on the west chair of the table, sun still shining down on him from behind. Hizashi’s laptop sat in front of him and he was looking at the notes already written down, color coded and everything from what Aizawa could see.
“No, it comes to me pretty quickly actually. I did one for you too, but I couldn’t ask you directly so most of the info comes from Hizashi.”
Aizawa raised a brow, Hizashi may have known him for a while, but only Aizawa truly knows how his quirk works and feels. Any case, he decided to humor Midoriya, “All right, shoot.”
“As you know, a lot of quirks seem magical at first with no real explanation behind it but I find that explanation boring so I figured out a way it might be possible to replicate your quirk with science. I think I heard someone say ‘magic is just undiscovered science’ before and I took it to heart. So! Bear with me, it’s a bit out there. There’s an extra organ somewhere near your eyes that produces sound, but at a low frequency humans can’t hear, and that frequency affects quirk cells, making them cease function. It would explain why it doesn’t work against mutants; their quirk cells are structured differently and may be resistant to the frequency. The eye socket is in the shape of a bowl, it would resonate the vibration in a cone shape and so, when you look at someone they’re both within the field of the soundwaves and your field of vision. Of course, if the organ or maybe even structure producing the sound is in your iris it would also function the same so that’s also a possibility. And remember how you said reflecting your gaze through a mirror doesn’t reflect the quirk’s effect? That would be explained with this!”
“That’s…really good actually.”
“Thanks!”
“Slight issue, if it’s a sound why does it not travel through walls? Or even cloaks.”
“You’re right…But if it was a high frequency sound the explanation still holds water!”
“I’m listening.”
“Well, humans can’t hear extremely low frequencies, but in the same way they can’t hear extremely high frequencies. Give me a second.” Midoriya typed away on the laptop while Aizawa took another bite. Midoriya soon turned around the laptop so the two could see the screen, a scientific article on soundwaves that Aizawa didn’t even bother reading since Midoriya already started talking again. “Here! Since low frequency soundwaves collide less with particles they travel further and aren’t as affected by obstacles. But the opposite is also true, high frequency soundwaves collide with particles much more and lose more energy in that process, making them travel shorter distances. It also makes it harder for them to pass through objects.” Midoriya turns the computer towards himself and types something else, after a moment he speaks up again, “High frequencies are also proven to affect cells, altering gene activity and cell structure! And I imagine that creating such a frequency would give anyone dry eye.” Midoriya looked very proud of himself for a moment before something clicked, getting serious and speaking in a lower tone.
“Hey…if it’s actually connected to sound and not something special with your quirk, can’t it be replicated? Why doesn’t the government just make quirk canceling cuffs?”
“Possibly, it’s not related to sound.”
“What makes your eyes different?” Midoriya spoke to no one in particular, thinking out loud, “Can you activate your quirk for me?”
“Sure.” And Aizawa did, for a moment. His hair turned weightless, floated upwards and his eyes turned red after he was sure Midoriya saw the full effect he turned it off.
Midoriya stared for a moment, “Now why the hell does your hair float!?” Midoriya turned toward the laptop, searching for any possible answer. “It’s possible the force of the sound pushes it upwards, but such a force would be noticeable…It’d also damage your eyes way past dry eye…” Midoriya hung his head in his arms and groaned. “That’s impossible, ignore that.”
“Kid, people create fire and ice out of thin air, ‘magic’ might be possible.”
“But that’s easy! Bind oxygen molecules together using a carrier molecule and create enough energy to spark it; create a ton of endothermic reactions to cool the air which would bring water molecules together and then also bring the temperature down enough to freeze them, water will expand when frozen anyway.”
“Okay, ‘magic’ still exists. You’re a crystal yet you move like you have joints and bones, you also regenerate slightly with sunlight; how do you think that works?”
“If my cells make up the structure, I'm guessing that they can also rearrange themselves quickly. And the regeneration? It’s photosynthesis, my body or cells, create crystalline structures and energy from the sun’s energy and surrounding materials like oxygen. I mean, organisms have been doing that before, and they’ve used silica and calcium carbonate. Speaking of, I did look up emeralds, they’re beryllium aluminum silicate so they are partially silica.”
“You’ve lost me.” Aizawa says. “Just now? I’ve been lost since he said high frequencies could affect cells or something.” Hizashi laughed at Aizawa’s dismay.
Midoriya snapped his fingers, “Could it be possible your quirk disperses extra energy created during vibration through your hair to avoid overworking your eyes?”
“And how would it do that?” Aizawa’s got to admit, he likes pointing out flaws, I mean, it’s helping Midoriya find an answer and also makes Aizawa feel like a smartass.
“Newton’s cradle, it can’t move your brain or skull; maybe because it’s attached to them, so the force transfers to your hair.”
“Sure…Still doesn’t explain why the government wouldn’t make quirk canceling cuffs if it’s replicable.”
“Perhaps they tried but couldn’t get the same results since they don’t know how your eyes are structured and what output is required.”
“I guess that’s plausible, nice thinking Midoriya.” He reaches out to pat his head and ruffle his hair, it’s a weird texture and honestly he won’t do that again, shit’s sharp. It’s like strumming a guitar except sharper. “Thank you. I wish I had some way to test it…” Midoriya whispered the last bit, thinking out loud.
“Maybe you do? If my eyes do create soundwaves a microphone on that level could pick it up.”
“I don’t think so, for a microphone to work the sound has to pass through…” Midoriya googles something. “Unless you have a microphone that can detect over 50 khz?” He raises a brow.
Hizashi speaks up, “Maybe UA has one? God knows what kind of equipment Powerloader has hoarder over the years. And I’m sure Nezu would fund this experiment if it peaks his interest which I’m sure it will.”
“Another day. For now, let’s just finish eating, clean up the guest bedroom for you Midoriya and go to sleep.”
“Can I bother you two with something?” Midoriya spoke up but as soon as the two’s attention was on him he shrunk into himself. “Never mind.”
“Come on, don’t be shy.” Hizashi pinched Midoriya’s cheek, trying to get a reaction.
“My name, Izuku Midoriya? It doesn’t feel right.”
“That’s true, you’re our kid now so you should have one of our last names.” Aizawa spoke. “Let’s flip a coin.” Hizashi excitedly said, pulling out a coin from his pocket. “Heads-it’s Aizawa. Tails-it’s Yamada.” Before Aizawa could object and suggest a better method the coin had already flipped and fell onto heads. “What? No, best of three!”
“Too late, you made your rules, now follow them.”
“Okay, while we clean the guestroom, you can fill out the quirk registration form. We will bring it in tomorrow along with the adoption papers and we’ll also change your name there. Then after we’re gonna go shopping. Sound good?”
“Yup, I’ll get to work!” Hizashi made his way to the guest room.
“And I’ll fill out the form; thanks.”
