A/N: So...this happened.

I know I said I'd finish AOZ before starting a new multi-chapter story, but I just couldn't wait. Boku no Hero Academia has taken over my inspiration at the moment, and I'm a slave to its direction. I hope y'all can forgive me . and I hope you enjoy this little project!

I've always wanted to write a timetravel fic. Tried it with Naruto, and I think I bit off more than I could chew. This one, however, I think I can manage it! I'm hoping to keep it just seven chapters lol let's see how that goes ^^;

This is a Kacchako story, so if you don't like that ship, you can do us all a favor and not read it. I understand it's not for everyone, but no one is forcing you to read my story. Thank you.

Disclaimer: Boku no Hero Academia do not belong to me, no matter how much I wish it otherwise.

'It's been about a week since then, and things are finally starting to settle down.' Aizawa Shouta thought as he sat down for his lunch at UA for the first time in a week. Eri was awake, recovering, and more than willing to work with him and the other pros in regards to her Quirk. She was just beginning to understand her powers, and with his help, was now at least able to turn them on and off at will. This allowed him to return to UA for about three days a week, because she still needed his help, and he would not abandon her.

Taking his first bite into the mild curry and rice he'd gotten from Lunch-Rush, he sighed. 'It's good to be back.'

He would never admit it, but he missed and worried about his students. Especially Midoriya and Bakugou. While their relationship had managed to mellow out a lot since their unsupervised fight, Eraserhead still didn't trust them on their own. Not yet. 'Now that Bakugou has his Provisional License, I hope things only get better between them.'

He let out a sigh, catching the attention of Yamada Hizashi, who had been talking while Aizawa had been thinking. "Something wrong?"

Aizawa sent his friend a blank look. "No—!"

A sudden, stifling presence descended upon those in the Teacher's Lounge, catching them all off-guard.

"What is this?!" Midnight shouted, on her feet as she looked about the room, trying to spot the source. She wasn't the only one.

'Is this another villain attack?' Aizawa thought, dread filling him behind his mask of indifference.

"Why do I feel the need to blame your class, Aizawa?" Present Mic asked teasingly, despite the situation. Adjusting his colored shades, he's expression hardened as the presence intensified. "Get ready!" He shouted in English.

Then, in the center of the room, bits of white energy began to merge rapidly before there was a powerful flash of white light that caused those in the room to cry out in pain at the blinding intensity. When there were no longer spots in their vision, the sight that greeted them confused them greatly, though none of them lowered their guard in their puzzlement.

Dressed in civilian clothes and looking a bit roughed up, were two young adults; one woman and one man. The woman was wrapped protectively in the arms of the man, her medium-length chestnut hair a tangled mess, her skin slightly pale. Her clothing, while a bit damaged, consisted of a pale yellow sundress that reached just above her knees, and white semi-formal sandals on her feet. The man had ash-blonde hair that spiked up in a shockingly familiar way, and while he was also pale, it was not as evident as it was with the woman. His attire consisted of a black form-fitting, sleeveless, under armor shirt, loose-fitting jeans, and black combat boots.

"Why...why do they look like older versions of your students, Aizawa?" Yagi Toshinori, also known as All Might, asked in shock. He was the most vulnerable one at the moment, and was therefore shielded by his peers from the possible threats.

Indeed, the man had a shocking resemblance to Bakugou Katsuki, and the woman looked alarmingly like Uraraka Ochako. It was a vastly disturbing discovery.

"Regardless of their origin, we should still attempt to administer First Aid." Snipe pointed out. "Someone should go get Recovery Girl and the principle while we try to asses their state of health."

"I'll go." Thirteen said, closest to the door. They left as quietly as possible, while Snipe and Aizawa approached the two adults, Eraserhead's Quirk activated.

They stopped suddenly when the man stirred, a low groan sounding from him as he blinked his eyes. Disorientated red eyes revealed themselves, and Aizawa pursed his lips in suspicion.

"Wha…?" The unknown man's voice was rough, deeper with age and having gone through puberty, but was mistakenly familiar to all who heard it. For whatever reason, this man looked and sounded like Bakugou Katsuki.

Midnight quickly approached the two, ripping up the sleeve of one of her arms. Kneeling before the half-awake man, she held her arm closer to his face as a pink mist burst from the exposed skin, and watched as his eyes widened in recognition, before they quickly closed as he passed out.

"I think it would be wise to keep them unconscious for now. At least after we have Recovery Girl examine them." Midnight said as she looked them both over, noticing that they both had a few cuts and shallow wounds. Nothing major, but if these two really were students of theirs, they needed to be taken care of. Nodding to herself, Midnight deactivated her Quirk as she stood up. "Okay, let's—"

She stopped when she realized the teachers nearest her were knocked out from her Quirk, and let out a sheepish chuckle. "Oops."

~o.8.o~

"It's a perfect match." Shuzenji Chiyuki announced as she removed her hands from the unconscious man and woman, who were in separate hospital beds. With blue hair pulled up in a high ponytail and dressed in a doctor's uniform, she turned to her grandmother. "I can see now why you pulled me from the hospital. The man's DNA matches that of Bakugou Katsuki from class 1-A, and the woman's matches that of Uraraka Ochako." Her Quirk allowed her to analyze the DNA of one person, and see how similar it was to another; her limit was six people at a time. She was very popular when it came to paternity tests.

Shuzenji Chiyo, also known as Recovery Girl, nodded at her granddaughter. "We had our speculations, but it's nice to know for sure." She gazed at the two, noting that they no longer looked pale, their skin having a healthy hue. 'The sedatives should be wearing off soon.' After Midnight had brought them in, Recovery Girl had healed their wounds, little as they were, and had then administered a mild sedative to keep them under while they waited for Chiyuki.

The sound of the door opening had both woman turning to it. Nezu, along with Aizawa, entered the room, closing the door behind them. "What's the verdict?" The small, white mammal asked.

"It's a perfect match." Chiyuki repeated.

"I see." Nezu mused. "The only probable explanation would be a chrono Quirk, considering the way they appeared." He looked at Shouta for confirmation, and the Underground Hero nodded in agreement. "Those things are rather rare and powerful Quirks, so not much is known about them." He was quiet for a moment, before he smiled. "Well, it's no use musing about it now! We'll just have to wait for them to wake up so we can get more information. Would anyone like some tea?"

As the principle went about making tea for everyone excluding Chiyuki, she had to go back to the hospital, Aizawa gazed silently at the young adults. He took in their mature, yet youthful appearances. 'They can't be more than a decade older than their current counterparts. I wonder what's happened in that time…'

Turns out, they didn't have to wait too much before the two youths began to wake up. The woman was the first to stir, moaning softly as she stretched languidly. The sound caught the attention of those present, and they turned in time to see her opening her eyes to gaze blearily at the ceiling.

"What...happened?" She murmured.

"We were hoping you could tell us that." Nezu said as he perched himself on the chair beside her bed.

Turning towards the voice, her eyes widened as she registered who he was, snapping up into a sitting position. "P-Principle Nezu? Aizawa-sensei?! And Recovery Girl?! Wha—?"

"Hello!" He smiled at her surprised expression. "It's heartening to know that you remember who I am, but to make sure, can you tell me your name?"

"Uh, Bakugou Ochako." She replied automatically, still numb with shock. She caught the surprise that colored their expressions, but was too stunned to comprehend the cause of said surprise. "Wha…" Her gaze began to wander about the room, taking in the appearance of those around her. 'They look so much...younger! What the heck happened?'

A grunt from behind cued her into the fact that there was another bed behind her, and she whipped around to meet the sight of the man waking up. "Katsuki!"

"Quiet down, Ochako." He grumbled as he pushed himself into a seated position. "You're giving me a f*cking headache with your screeching." Rubbing his forehead, he paused mid-motion when he took in those around them. That's when the memories slammed into him like a sledgehammer. "F*ck."

Ochako was just about to ask him if he knew what happened, when her own memories managed to get through her surprise. "Oh!"

"Now that you're both awake," came a familiar, bland voice, and both young adults turned towards Aizawa as he approached them a bit, "can you tell us what happened?"

"Ano, before that, can you tell us what year it is?" Ochako hedged. "Since you three are here, Imma assume we're at UA, but I'm not sure...when." She turned to Katsuki, and he shook his head.

"It's the second semester of your first year." Nezu supplied.

"So...seven years. Just like they said it would." Katsuki mused. "That means seven days. F*cking great."

At their questioning gazes, Ochako smiled nervously. "I'll explain. We were in the middle of date night when we ran into Deku-kun! He was babysitting Akira-chan for a co-worker at his agency, and had decided to take her for ice cream. It was all of our days off, ya know? We stopped to chat for a bit, when a villain came out of nowhere. He was a low-level thug, nothing we couldn't handle, but his sudden appearance startled Akira-chan, and she activated her Quirk."

"So it wasn't the work of a villain." Nezu confirmed. "So, this Akira-chan; she has a time Quirk?"

"Yes." Ochako confirmed. "It's called Backtracking. She can send anyone in physical contact with her back in time, but is limited to her own age. She can't send people back to a time where she does not exist, and the effects are temporary. A day for a year. So, Akira-chan is seven-years-old, so we'll go back to our time period in seven days."

"What about the affects your presence in the past will have on your future?" Aizawa asked, bringing to light a very serious concern.

"It won't do shit to the future." Katsuki answered. "Since we come from a future that already happened, we cannot change events. They will still happen, one way or another. Our presence may delay or accelerate certain events, but the result will be the same. Time paradoxes and all that sci-fi shit—that doesn't apply here."

"Well, that's a relief." Recovery Girl sighed. Nezu and Aizawa nodded in agreement.

"Since our main concerns have been address, I see no need to keep you from the rest of the students and faculty." Nezu announced with a smile. "Since you'll be staying with us for a week, you're more than welcome to stay on campus. I'll be sure to let everyone know that they are not to pester you about the future."

Katsuki smirked. "And take all the fun away?" Ochako giggled, but quieted as the blonde became serious. "You're right to assume we won't be talking about the future much, if at all. Just because being here won't f*ck our future, that doesn't mean knowing it will do anyone any favors. However, there is one thing I'm willing to help out with."

Nezu leaned forward in his seat, intrigued. The temptation of knowing the future was a great one, but his advanced mind could already calculate the consequences of having such knowledge, especially with the fact that nothing they did could change it from happening. He figured he'd take the initiative and tell those on campus not to pester the two, because there was no way he'd be able to keep their presence a secret. Not with someone like Bakugou Katsuki's headstrong personality. "And that is?"

Katsuki met Ochako's eyes for a brief moment, and she nodded. It was something they had talked about before; one of the few 'what if' conversations that happened late at night after a particularly bad day. He knew she'd agree, but he respected her enough to still get her feedback before moving headstrong into a decision. Turning back to Nezu, his expression hardened. "The rat among the faculty. We know who they are."

~o.8.o~

The halls were quiet as Aizawa led the older versions of his students towards his class. It was not an uncomfortable silence. His thoughts couldn't help but wander back to the nursery.

-.-.-

"Are you certain?" Nezu asked as he stared at Katsuki.

The blonde nodded. It was a testament to how much he had matured that he didn't become defensive at the non-existent insult he would have perceived it to be as a teenager.

"Why are you telling us?" Aizawa asked.

"Because it's worth the f*cking risk." Katsuki stated.

"Telling you this will either delay or speed up events." Ochako explained. She glanced back at her the blonde, then back to her old sensei. "However, I agree with Katsuki. If you do this right, you could delay things for a bit longer. That will give you time to...prepare yourselves." She said the last part in a low tone, her gaze averted.

"I see." Nezu muttered. 'This is a gamble, as well as a burden on them. They could tell us what happens, but we would be powerless to change anything. By the set of their expressions, it must be unpleasant, and frustrating, to know they can't change anything, either. They've done their best to give us a chance to better prepare ourselves for the trials ahead, yet in doing so, our time could be cut in half. A gamble indeed.' He smiled at them. "Thank you for giving us this information. It will save us a lot of effort, and I will do my best so that we gain time, and not lose it."

-.-.-

Shouta was still surprised by who the traitor was, but there was nothing he could do about it. He was levelheaded enough to accept that there was nothing he could about it, frustrating as it was.

Pausing outside the class door, he turned to the two with him. "Class is almost done for the day. Right now, they're with Cementoss and will be returning shortly. I'll introduce you then." He glanced down at the wedding bands on their ring fingers before meeting their gazes. "While I'm surprised at the change in your relationship, I don't really care. The students, however, are bound to get excited about it. If it's something you want to keep a secret, I suggest you do something about those."

Ochako grinned knowingly, before casting a sly glance at her husband. "Thank for looking out for us, sensei, but even if I wanted to keep our marriage a secret, Kacchan won't let me."

"I told you not to call me by that f*cking name, woman." He glared, but there was no heat behind it. Instead, there was a suspiciously pink tint to his cheeks as Ochako giggled.

Aizawa stared for a moment. "Right. Whatever." 'I think I'm going to be ill.' Without another word, the erasure hero opened the door to class 1-A and led them inside.

"Oh man, it's been forever since I've seen this place!" Ochako gushed. A feeling of nostalgia washed over her in that moment, and she gazed fondly at her seat. Walking up to it, she reached out a finger and tranced the faux wood patterns on its surface. "This is where everything began." She whispered. Noticing movement from the corner of her eye, she turned her head slightly to meet Katsuki's gaze from across the room, and smiled softly at the look in his eye.

He was feeling it, too.

The steadily rising noise of teens making their way down the hall brought her completely out of her reverie, and she quickly made her way to the front of the class where Aizawa and Katsuki were. Taking her place at her husband's side so she was closest to the door, she stuck her tongue out at him when he glowered at him. The man was so competitive that he had to be first at everything, including the first thing everyone saw. It was ridiculous, and she enjoyed messing with him when she could.

Ochako blushed with a small smile on her face, and giggled mentally. 'Well, first in most things.'

At this point, they could make out the voices of the students as they neared the door, their conversations discernable.

"...gotten a lot more difficult…"

"...won't be in class tomorrow. Ryu…"

"STOP F*CKING TOUCHING ME!"

Ochako couldn't help the giggle that slipped from her at that familiar outburst, and felt more than heard Katsuki shuffle awkwardly behind her in embarrassment. She kept her gaze on the door, wanting to see their reactions as they walked through the door.

She wasn't disappointed, as the first one to open the door was Iida Tenya. He had been halfway through ordering the class to enter the classroom in an orderly manner, when he'd spotted her. His eyes widened in shock as he stopped in the doorway.

Ochako grinned before waving. She mentally giggled at his mouth was left ajar. 'Okay, maybe Katsuki is rubbing off on me.'

"Iida?" Midoriya Izuku asked from behind his friend. "What's wrong?"

"Alright, that's enough." Aizawa cut in before the Class President could recover. "Get in here already and sit down. I have an announcement to make, so keep quiet." At his words, the class did as they were told. One by one, they noticed the visitors; one by one, they noticed the similarities they shared with two of their classmates.

The surprise was visible on both Uraraka's and Bakugou's faces when they saw their counterparts. The man merely glanced there way for a moment before averting his gaze, while the woman winked at Uraraka with a knowing smile. Confused and surprised, the two took their seats without a word, heeding their teacher's words.

"Now then," Eraserhead began when they were all settled, "I know you're curious about our visitors, but I'll get to them in a moment. First, I want to touch on a few things. There is a test on Hero Law tomorrow, so be prepared. Bakugou and Todoroki; because of recent developments, I'll need your Internship Request forms by tomorrow morning the latest. If I'm not here, you can hand it over to Present Mic. Understood?"

At their nods, he continued. "As for these two," he gestured to the future counterparts, and decided to go with a vague introduction, "they are exactly who you think they are. Due to an accidental use of a chrono Quirk called Backtracking, they have been sent back seven years, and will be with us for a week. There will be a formal announcement tomorrow for the rest of the campus, but you lot are being informed now for obvious reasons. Don't pester them about the future."

"Sensei!" Iida asked loudly, his hand raised rigidly. "Are we sure these two are Uraraka and Bakugou?"

Aizawa nodded. "We had a hospital official with a Quirk for testing DNA by touch come to confirm it."

'That's why that b*tch messed with my hair.' Bakugou mused as he continued to stare at his older counterpart.

"Now, if there aren't any more questions, not related to the future," he stressed when hands went up. They all went down, and he continued, "you're dismissed for the day." He then turned to the other adults in the room. "Do you need directions to where you'll be staying?"

Katsuki opened his mouth to speak, most likely declining the offer. 'Always so prideful.' Ochako thought fondly as she pressed a finger to his lips, silencing him. It was such a natural reaction for her, that she didn't even think of the effect such a gesture would have on the class. Focusing on Aizawa, she smiled. "Sure, Aizawa-sensei. We'd appreciate it."

"Woman!" Katsuki growled as he snatched her hand away from his face, but he kept his gentle hold on it. "Don't 'shush' me!"

Ochako merely smiled. As if realizing they had an audience, her chocolate eyes drifted towards the class, and a blush warmed her cheeks as she merely intertwined their fingers and waved at the class.

Following her gaze, Eraserhead took in their shocked expressions, and mentally sighed. 'Knowing this class, they're gonna cause more trouble than necessary.' "Alright then." Turning around, he led the couple out of the classroom.

The class watched as the adult versions of Bakugou and Uraraka left, hand-in-hand.

~o.8.o~

"This is where you'll be staying for now." Aizawa said. It was one of the spare rooms they had available; an adult twin bed, a desk, and a bathroom. "It's a bit cramped for two people, but it's all we have."

"Oh no, it's perfect!" Ochako reassured with a smile. "Thank you so much, sensei."

Aizawa stares at her for a moment, feeling that something is off. Older they may be, they were still his student, and he knew their tells. 'Something's bothering her.' He glanced at Katsuki, and noted his intense stare on the young woman. He nodded. 'It's not my place.' "Don't thank me, it was all Nezu's doing." He turned to leave. "You're free to roam the campus at your leisure, and while you're not restricted to school grounds, it's probably for the best that you don't leave." At their nods of agreement, he continued. "If you need anything, my room is the third down to the left. Good night."

"Aizawa-sensei is such a softy." Ochako giggled softly once the door was closed. "He says it wasn't his doing, but he's just down the hall to us. That sounds just like something he would do, don't you think?" She didn't wait for Katsuki's response as she turned to look around the room, not looking at her husband. "Wow! I forgot how small these rooms were." She said this as she approached the bed. "It's a good thing you're such a good cuddler, ne, Katsuki? At least we have a bathroom to ourselves, but we do have to share the showers."

As Ochako continued to ramble about the room, Katsuki made his way behind her, resting his hands on her shoulders. "Shut up." He said needlessly, as she had quieted at his touch. He felt her shoulders tremble as she let out a soft sniffle, and wrapped his arms around her waist. "I f*cking hate it when you put that stupid front up with me."

"I-I'm sorry." Ochako said as she turned around in his hold and pressed her face into his chest. He was so much taller than her, she could barely reach his chin. "I didn't want to seem weak." Came her muffled reply.

Katsuki gritted his teeth before pulling her back enough so he could stoop down and press his forehead against hers. Burning ruby glared into glassy chocolate brown eyes. "You're not f*cking weak; I wouldn't have married you otherwise." His gaze softened a touch as he brought up one of his hands to gently cradle the back of her head, keeping their foreheads connected. "I wouldn't love you if you were weak."

His gruff reassurance only seemed to make Ochako more emotional, her mask gone as she let a few tears escape down her rosy cheeks. "We can't change anything."

"It f*cking sucks." He murmured in agreement, never breaking eye contact as he wiped her damp cheek with his other hand.

"A-and we could have made things worse."

"I know."

"I don't want them to g-go through what we did…"

"...Me either."

"I'm worried about Kyohaku."

At that, Katsuki moved to kiss her forehead, his eyes closed. "The old hag will take care of him. He's tough, like us." He then maneuvered them so that his arms were once more around her waist, her head resting against his chest. They stayed like that for a long while, soaking in the presence of the other.

A random thought struck the zero-gravity hero.

"We need clothes." Ochako mumbled, not wanting to move from her spot.

"We've slept naked before." Came Katsuki's lazy response.

Ochako squeaked at his words, moving away just enough to smack his shoulder. "I meant for tomorrow!" She retorted, face red.

The ash-blonde scoffed at her reaction, a smirk on his face. "Right, whatever." He pressed a chaste kiss to her lips, silencing her indignant response, before releasing her completely. "I'll go bother Eraserhead about the clothes. Stay here."

Huffing, Ochako watched as he left. Taking a seat on the bed, she didn't the stop the gentle smile that crossed her face as she stared at her folded hands in her lap. "That man…"

~o.8.o~

"Are we just going to ignore what happened?" Todoroki asked, surprising the rest of his class. They had just finished having dinner in an awkward, tense silence, and were now seated in the living room in an awkward, tense silence. The fire and ice user was done with it. He watched his friend look uncertainly amongst themselves, and how Uraraka and Bakugou in particular became more on edge. In fact, he was surprised they hadn't left for the rooms already.

"Well, there's not much to talk about." Ojiro Mashirao hedged as he cast a glance between Bakugou and Uraraka. "They're from the future and they'll be with us for a week."

"And they're together." Aoyama Yuga pointed out, touching upon what they had been avoiding. "Romantically."

"We don't know that for sure." Yaoyoruzo Momo argued gently, taking in the Uraraka's blushing face. Her face reddened further upon hearing Mineta grumble about how 'lucky' Bakugou was, before Jirou silenced him with an ear jack to his neck. "For all we know, Bakugou and Uraraka-chan just become close friends." She offered, though she knew it was weak considering their display earlier.

"Why don't we just ask them?" Kaminari Denki suggested.

"We were instructed not to pester them about the future." Tokoyami Fumikage reminded them.

"Tokoyami-san has a point." Midoriya agreed. "Besides," he met the gazes of Todoroki, Iida, Yaoyoruzo, and Kirishima Eijiro, "we're still trying to win back Aizawa-sensei's trust."

The reminder of the Kamino Incident stopped all conversation, and the atmosphere became tense for a whole different reason. Guilt and frustration settled over them.

Bakugou gritted his teeth. It was sickening.

Shooting to his feet, he glared at his classmates, pointedly ignoring the gravity manipulator. "It doesn't matter if we go or not; we're not going to get shit out of them. I know myself, and I wouldn't say shit to you f*ckards about something like the future, so you're wasting your damn time." Taking in their startled expressions, he tsked when he caught sight of Kirishima's knowing smile. "F*ck you all, I'm going to bed." With that, the hothead of 1-A made his escape.

"Man, he's right." Kirishima grinned. "Future McSplode won't tell us anything, and Uraraka-san has always been one to follow the rules." He then became serious. "And Midoriya has a point; we're heroes in training. We can't keep breaking the rules." He looked down at his hands before fisting them. 'No matter how much we may want to.'

If any other student had said what Midoriya and Kirishima had, they would have scoffed at it. A few may have even snuck out in search of the time travellers. However, because it was them, the class accepted it and dispersed, heading to their rooms. It had been a long day for all.

On autopilot, Uraraka made her way back to her dorm room, her face still flushed a seemingly permanent red hue. Ever since the arrival of their future counterparts, her thoughts had been in turmoil. She had sworn off romance in favor of pursuing her career; was still getting over her feelings for Midoriya. 'But now…'

As she got ready for bed, the sight of the wedding bands on their ring fingers was all she could see when she closed her eyes.

And there we have it! I'd love to get your feedback!

If you have anything negative to say about it, it better be constructive. I will not tolerate any bashing just because you don't like this ship. You knew what you were getting into when you clicked on this story, so that means you were looking to troll, and I will call you out on it.

Sorry about that, I just feel like I have to make that clear.

Until next time,

Ja ne!
