Unexpected Confrontation

"Oh shit."

Oh shit is right. The man standing in front of Izuku, his father, Midoriya Hisashi, was also the 200 year old supervillain All for One, not the humble, fire-breathing salaryman he thought his father was. But he has slightly more pressing issues right now, because of the expression on his Dad's face, he said that aloud.

"Izuku, where did you learn that?" Hisashi - All for One, apparently - said with a stern expression.

"I- uh- er- All for- you- Dad- wha-" Ok deep breath, calm. Fix this. "A-Aunt Mitsuki." Hisashi raised an eyebrow.

"Mitsuki." He deadpanned. Izuku nodded so fast you'd think he'd snap his neck. "Right, well how about you help me put all of this away? There might be a suprise in it for you."

Izuku all but leapt off the couch, eager to get away from his embarrassment with almost revealing himself not even an hour after he jumped back (to All for One of all people!).

It didn't take long for the groceries to be put away; there weren't many of them to begin with after all. With a quick "c'mere", Izuku was lifted and seated on Hisashi's hip. "So, little man," Hisashi started, "Want to tell me the reason 'Aunt Missy' is suddenly 'Mitsuki'?"

Izuku froze, looking like a deer in headlights, "Uh." Eloquent.

"And the reason why you know my alias? Or perhaps the reason why when you saw me you looked as though you were staring death in the face?"

"I- um- er-" Izuku stammered. He knew, in this moment, he fucked up. He knew from the beginning suddenly being a 27 year old in a 3 year old body would be jarring, and that it'd take some time to adjust. He knew he'd act strange and different to how he was supposed to have acted yesterday to everyone else. He also knew that he'd have to reveal at least something sooner or later to his parents. But he didn't think it'd be to him, ever.

Izuku took a deep breath to calm himself, as well as to prepare himself for everything.

"I-" He started, feeling not at all prepared for this. "Not really, no."

"Let me rephrase then. Tell me. Now. You have ten seconds to start explaining." Izuku contemplated telling a lie, then scrapped that plan almost as soon as he thought of it. He was never a good liar, and never really had the need to learn how to be. All for One would see through it instantly, if he didn't already have a Quirk for that. No, Izuku's only option was the truth. Not a half-truth either, everything would be forced out of him one way or another.

"Would you believe me if I said time travel?"

"Time travel?" All for One stared at him in mild disbelief, but whether that was from what Izuku said or how easily he caved, Izuku didn't know.

Izuku nodded, "Yes. Time travel."

Hisashi walked the two of them to the dining table and sat Izuku down across from where he then sat. "Go on," he prompted.

"Well, to put it simply, everything went to shit. Noumu were everywhere and what was left of civilization was being hunted by them as well as an overpowered Shigaraki Tomura hellbent on revenge. We were incredibly lucky that Chou-chan was still alive and willing to help us - she hasn't been born yet so don't even think of looking for her - and it was a majority decision for me to be the one to go back. But Chou-chan can't exactly practice her quirk so it's unstable and the further back someone is sent then the less accurate it'll be. I was meant to arrive about the time when I was nine, but, uh, here we are I guess. Though I wonder if it's possible for her to use it on herself? And if so would that allow her to get more practice that will carry over after the jump? What would happen to someone if they're sent back to before they technically existed-"

"Izuku you're mumbling." He jolted out of his mumbling session and looked back up.

"Right. Sorry, never really broke the habit. Anyway in the end there was maybe a thousand or two people left, with six of us being heroes and one being our support technician. It's unknown how many Noumu there were - do you know what a Noumu is? Wait you shouldn't because when they first appeared they were still in the experimental stage, nevermind - but there was an estimate of at least 3500 when they were at their peak and approximately 500 in the end, but there could've been more." Thank god that Hitoshi couldn't see him right now.

All for One just stared at Izuku, contemplating what he was just told. He took a breath and exhaled. "As ridiculous as this all sounds, I have no reason to doubt you - I have a truth telling quirk," Hah, called it, "but since you told me so very willingly, I won't tell Inko," Izuku sighed in relief, "yet. She will have to know eventually though. Now." Hisashi reached into his pocket and took out an All Might themed cookie. Izuku brightened up immediately when he saw it.

"Is- is that an All Might Chocolate SMASH™ cookie?!"

"Perhaps. And it's all yours." Izuku reached for it and immediately began tearing up as he stared at it in his hands.

"These haven't been in production since the factory blew up back when I was 8 and the recipe was lost! Thank you thank you thank you!" Hisashi grunted as he was tackled by his 3(27) year old son, but a smile quickly found its way onto his face.

"I could always get the recipe for you so we can make them at home if you want-"

"Really?! Oh but please try and keep the illegality of it down."

"I'll certainly try." Hisashi said, huffing a laugh.

Soon the two of them had settled onto the couch and were watching TV, basking in a familiar warmth.

"Hey Dad?"

"Yes Izuku?"

"Do you have a spare notebook I could use?"

Page 1: Introduction

If you somehow found and worked out the code to this, congratulations. That must have taken quite a lot of work you probably should have spent on something else.

I am Midoriya Izuku, hero name Deku, and this will be the first of a (potential) series of notebooks, seperate to my analysis ones. It will contain all I can remember of major events and people leading up to the day I traveled back in time.

When I woke up after the time travel quirk was used, it was the morning of the 12th of December 22XX - exactly 24 years, give or take a few hours. That's 24 years of people and events to observe, remember, and potentially recreate or change.

Each entry will have a double spread, with the page on the left what originally happened during that event/that individual's profile for the previous timeline, and the page on the right will be reserved for the changes in this new timeline. If the right page is blank, that means there is the event hasn't happened yet, or I have yet to meet the individual to document any changes. As I will also (re)create my analysis series (albeit, neater than last time and in a different code to this series), some profiles will double up. However, the profiles in this series will focus more on the person as a whole and the differences between them in the two timelines, rather than strictly analysis of their quirk and battle prowess.

Please note, I cannot be certain what theory time follows, and what effect my actions will ultimately have. For now I will assume and act as if it is the butterfly effect, but again, I'm not certain.

I'll end this introduction here, but it should also be noted that I'll add entries of people when I remember to or if I meet the person again and entries of events in the order they happened in the previous timeline. If there are events that didn't happen last time I'll add them as they happen.
