Chapter Text
Hisashi closed his eyes and took a deep breath in. How long has he been here again? A week? He didn't bother to keep counting his days when he didn't even age, it didn't matter to him. Time has no importance to him. Not since…
Forget it. He shouldn't be stuck in the past. This is his life now and he got this second chance to finally protect his son. Again. Hopefully he'll actually do his job as a father better this time. He can't fail. How could he? If he fails.. He couldn't face his family ever again… If he ever sees them that is. No… It wasn't really fair to either of them if he just walked into their life. He's a stranger. The unwanted guest.
Besides, he doesn't want them to get killed. He can't. Seeing Izuku was already hard enough. He doesn't think he could face seeing Inko…
Stop it, this isn't the time for him to sit and think these awful thoughts. He has already gone two years lying around in his house, praying for some miracle to happen. In a way, it did happen…
He should thank Yagi after the war is over. He probably would've still been in his house drinking away his life and going crazy over a machine he rebuilt over and over again. God he feels so stupid looking over that now. Building a time machine? What was he thinking? But grief does some crazy shit on people. Even the oh so great demon lord.
Hisashi finally lets go of the deep breath he was holding in and gets up to train his body until he's exhausted. He can't let history repeat itself again. As much as he hates seeing Izuku going into the battlefield, this was their fight. He's just in with the ride as support. More like a secret weapon ready to drop in like a bomb.
He’s ready to die for his son. He won't be taken away from him again.
He won't fail his son and wife in this universe.
“Midoriya shounen, is something wrong?” Midoriya snapped out of his daydream and looked up at Yagi who was standing looming over him with knitted brows. Midoriya quickly waved his arms around and smiled nervously. “Ah! All Might..! It’s nothing, I've just been thinking a lot lately…”
Yagi smiled and sat down next to the boy with his hand on the boy’s back. “Is it about Hisashi?”
Midoriya turned to him in surprise and nodded. “Yeah, It’s just that… I don't know, he feels off. Not in a bad way! I just get the feelings that he's sad all the time. All Might you said his son died right? I think he's still thinking about that when he's with me. I mean, how could he not? I look like him but I'm not his son. Not here.”
Yagi hummed and nodded when he heard Midoriya’s explanation. “I understand where you're coming from. But my boy… You also have to understand that calling him ‘dad’ is a little too far. He's still in grief and it never stopped. Sure he might’ve gone along with it and be happy to be called dad but it's still too early. He's still trying to make peace with his family's death and with you calling him dad. It’s making him feel conflicted inside. So of course you're going to see him a bit off.”
Midoriya frowned and fiddled with his hands in guilt. “Okay yeah that was stupid of me to call him… I wasn't thinking clearly, I’ve never seen my actual dad before and my dumb ego got to me trying to spite my own dad. I'll try talking to him and apologize.”
Yagi grinned and patted his back. “Good, now come on. I have to get him as well, the costume department team had already finished with his costume design. But I have a feeling that he'll hate and love it. Mostly hate.”
Midoriya chuckled as he stood up with Yagi. “I’m sure it'll be fine. Beside It’s kinda his fault for not wanting to design it himself right? I over heard Power Loader saying something like that at least.”
Yagi threw his head back and let out a bark of laughter. “Hah! You're right about that my boy!”
Air walk, spikes, fire breath, barrier, strength, speed, far sight, fucking blast or whatever. He doesn't need to know the names. He just needs to remember how to use them, which is pretty easy once he gets used to it again. He just needs some warming up to do. Alright, let's see what quirks he got in here that he forgot about.
Detonation touch. It's a emitter quirk type. The user can cause an object to explode by touching an object. The object will begin to explode after a few seconds of initial touch, meaning the user can touch and go if needed and then boom. They'll explode into pieces.
Cellular regeneration. Quirk type, transformation. When a user is touched, they'll regenerate from any damage that they have received instantly. Hisashi favors this quirk a lot, it's super useful. Especially when he almost got punched in the face. That was terrifying.
“Hey, Hisashi. Are you done with training?” Hisashi turned around to the voice. Yagi-san… Oh yep, the memories of almost being ground beef is as clear as day alright. Oh and Izuku is here too.
“Yeah, just a second. I’m sweating all over the place.” Hisashi slid off the giant rock and walked over to them, smiling at Izuku.
“Did you get ripped or is it just me?” Yagi switched to English as he observed Hisashi's muscles with wide confused eyes. Hisashi smirked smugly. “What? Wish this was you? Mister symbol of peace.”
Yagi eyed him suspiciously, not believing that this was from hard work. It doesn't make sense since it has only been a week. “That is not natural… Did you get plastic surgery?” He joked.
This bitch “No, it's a quirk of mine. Pretty useful right? I am able to reverse my age, my whole life basically.” He explained to them as Yagi and Izuku looked at each other in surprise. He got a feeling that they were exchanging a glance of communication.
“So rewind?” Izuku asked him with a surprised but yet confused look because how would that even work? The timeline doesn't add up if Eri wasn't born yet and he was 90% sure Hisashi was in the past considering their timelines so that means he would be 6? So Eri wasn't born yet-
“Izuku you're muttering again. But no, the quirk is not from whoever Eri is. It's called ageless. I can change my age to whatever age I want but if I wanted to turn myself older that's impossible if you didn't make it to your maximum age. Like if I was 50 and I reversed my age, I know what I would look like when I was 50 so I can easily change my age back to 50. But if I never experienced being 50 before, I can't age up to 50. Do you understand how the quirk works now?”
Hisashi looked at both of them as Izuku was nodding at the explanation and- (Wait when did he get that note book? ) wrote it down quickly. Yagi was interested by the quirk and was probably thinking of all the possibilities of it.
"So does it work for others as well or is it just you? Wait does it heal any injuries?" Yagi asked him as Izuku was writing everything down on his
“That's interesting, so how far did you actually make it to? Your age I mean.” Yagi looked at him. Hisashi sheepishly rubbed the back of his neck and whispered it to him.
“What? Sorry I couldn't catch that.” Yagi asked again, not quite sure what he said to him.
“Twenty six…” Hisashi embarrassingly said to him as Yagi and Izuku blinked at him.
“Twenty… six? Huh. Well no wonder why you're short. You must be younger right now then.” Hisashi shot a glare at Yagi as he chuckled and stopped with the short bullying.
“Wait, so you must be around twenty right?” Yagi asked for some confirmation.
Hisashi sighed and muttered under his breath. “I'm about fifteen.”
Silence filled the room awkwardly.
“So you haven't hit your growth sprout yet?” Izuku breaks the silence. Hisashi smiled, feeling betrayed by his own alternate son. That smile doesn't mean he was confirming it happily, no he was trying to hold back his tears. What is up with all them and calling him short? He hates loves it here.
