Summary:

Titans are now a thing of the past, believed to be a mere myth. Levi Ackerman is now having a second chance at life, with all his past memories intact. Now in his junior year of high school, he despaired of ever finding his long lost love. At least until a certain green eyed freshman turned up, and he then feared that she might not remember him. Levi/Fem!Eren

Okay, I know that I have no excuses for churning out story after story when I have about twenty other stories on my account waiting to be updated! But anyway, I've been reading a lot of reincarnation stories lately, and I feel like starting my own, only one with a female Eren.

Pairings: Levi/Eren

Warnings: AU Universe. Reincarnation. OOC. Gender swap. Taller Levi. Shorter Eren.

Disclaimer: I do not own Shingeki no Kyojin or any of the characters, but the OC characters belongs to me

Chapter One: To You, 2000 Years From Now

Levi doesn't know when it had even begun—when he had first started falling in love with the brat who also happens to be his ward, and whom he had also been tasked with killing should she showed any signs of being out of control.

He still remembered the first time that he had seen her—when the Survey Corps were summoned hastily back to Wall Maria due to a breach in the wall when the Colossal Titan had all but kicked a hole in the wall—the same thing that had happened when Wall Rose had fallen.

Levi still remembered arriving at the Trost District, fully expecting their mission to be one of retrieve and rescue, not a mission to eradicate all Titans currently within Wall Maria. He also distinctly remember cutting down two 10-meter class Titans that were both about to eat three recruits who seemed to still be trainees in the Academy—probably from the batch that is soon to graduate in a month.

Levi had been confused momentarily with seeing an already disintegrating Titan carcass near the breach in the wall that had been sealed with a large boulder, with the brunette trainee looking as if she is about to fall over from exhaustion. And why the hell is she missing her uniform and gear?

It is only later when Levi had gotten the full details from Erwin, and that the brunette—one of the Academy brats had turned out to be a Titan shifter, and had also been essential in the victory over the Titans during the Trost incident.

Levi had only gone down to the cells with Erwin out of curiosity after they've finally gotten permission to visit Eren Jaeger. But he later found that he'd liked what he'd seen in the eyes of the green-eyed brat. She had a fighting spirit, and that same fire that could also be found in every single one of his team members.

Then the 57th Expedition had happened, and it took Levi every ounce of his persuasion skills to even make Eren eat just a little and even to sleep. Even so, Levi had to stay near her just to make sure that whatever little amount of sleep that she could get, she could sleep without any nightmares from haunting her dreams at night.

Levi didn't like how dull that Eren's eyes had been. Oh, he knew the reason why. The brat had seen just about every single one of her teammates get killed by the Female Titan, and the brat herself had also been almost abducted by said Titan if Levi and that Ackerman brat haven't turned up and grabbed Eren back.

It was barely a year later when they've first gotten together—when Levi had woken up one day only to realise that he loved that brat. The brat that always made sure that he had a cup of warm tea waiting for him, and that he always had a fresh change of clothes. The once scrawny brat had also blossomed beautifully; being more of a woman that Levi sometimes had difficulty taking his eyes off her, and also had difficulty controlling his thoughts.

Now, three years ever since he'd first laid eyes on the green-eyed beauty who'd stolen his heart, and two years ever since he'd told her that he had loved her and vice-versa, Levi is now waiting in the hallway of the Survey Corps' headquarters, praying for the first time in his life that Hanji wouldn't come out and tell him that another of his friends is dead.

The Survey Corps had done their duty in the war—having eradicated most of the Titans in the world. The final battle had just occurred less than six hours ago when they were up against highly intelligent Titans that seems to possess human intelligence, and even the 'King' Titan – the Ape Titan.

It is almost like fighting an army version of the Female Titan aka Annie Leonheart.

As for the other Titan Shifters apart from Eren however, Reiner Braun and Bertholdt Hoover have both appeared again after nearly a year ever since their disappearance, and after the entire incident involving the Central Division of the Military Police, turning themselves in.

Erwin had spent nearly an hour talking with them after that, also involving Hanji and Eren in said 'talks'. Levi doesn't know what had actually transpired in those 'talks', as even Eren had refused to tell him, but the long and short of it is that Erwin had decided to involve the two Titan Shifters in the efforts of retaking back their land along with Annie Leonheart when the other two Titan Shifters have managed to 'convince' Annie to come out of crystal stasis.

…Hanji had a blast examining the remains of the crystal that Annie had crystallised herself in.

The other three Shifters were also given the same ultimatum that Eren had been given when Levi had first taken her into his squad—prove their loyalty to mankind and the Survey Corps by fighting for them or die.

Needless to say, the Titan Shifters have contributed greatly to their final stand against the Titans. Lots of people have died however, during the final battle. Reiner Braun and Bertholdt Hoover have perished in the battle as well, and Annie Leonheart had followed them not long after that.

Ymir had remained behind in Wall Rose to guard Historia Reiss, as not even Erwin is willing to risk the life of the future Queen in this dangerous mission. Probably, that had been the only reason why Ymir and Historia are still alive. Out of the 104th Squad, the only survivors have been Mikasa, Armin, Connie, Sasha and Jean.

As for Eren…

One of the two last known Titan Shifters is now fighting for her life inside the infirmary after Mikasa Ackerman and Armin Arlert have brought their sister back, half dead and barely breathing, with none of her wounds healing on its own like how they usually would.

The doors to the infirmary opened just then, and Levi sprang to attention immediately even as Hanji stepped out, blood visible on the gloves on her hands, and a sombre expression in her eyes. Levi almost felt his heart drop down to his boots at that—he had seen that expression often enough on Hanji's face whenever she had to bring news of a comrade's death to their family, and to inform them that their son or daughter or wife or husband wouldn't be coming back.

Please no…

"She doesn't have long left now." Hanji said solemnly, not even bothering to sugar coat her words, and she almost cringed as she saw the light leave Levi's eyes.

Ever since the deaths of his two best friends and then when his entire squad was killed, Eren had been the only bright spot in his life—the only thing preventing him from going off the deep end. Both Erwin and Hanji have been thankful to her for it, and it isn't only because of her status as a Titan Shifter that had kept them fighting the Military Police, refusing to allow them to get their dirty paws on the green-eyed brunette.

"I can't do anything anymore." Hanji told Levi, upset. "Even Titan regeneration have limits to what they can do, and Eren had already overtaxed her healing ability during the fights earlier. It is as much the same reason why Braun, Hoover and even Leonheart have died." Hanji looked upset. "I'm sorry. Go and see her…" Her lips trembled. "F-For the last time."

Hanji then left the hallway, not wanting Levi to see the tears in her eyes. Mikasa and Armin exited from the infirmary not long after that, with composed and hard-hearted Mikasa Ackerman crying, and even Armin Arlert's eyes were red.

Both teens stopped in their tracks when they saw their commanding officer in front of them, and also their sister's lover. Levi almost couldn't look into their faces.

Mikasa had been the most vocal when they've finally came out about their relationship nearly a year ago only to members of their own squad, as it will only be a matter of time before the rest of their squad figured it out for themselves once Eren stop sleeping in her own room.

"Will you swear to protect her? Can you keep Eren safe?"

Mikasa grabbed hold of Levi's arm tightly, and he was then forced to look into her dark eyes that held a hint of desperation within them as well as pain. "You told me once that you intend to marry my sister after the war is over." Mikasa said, desperate, recalling the conversation that she had with the shorter man not too long after the new Squad Levi had learned about Levi and Eren's relationship with each other. "Do you still mean it?"

"…Yes."

Mikasa looked about ready to burst into tears at that, and Armin placed a comforting hand on her arm even as she turned back towards Levi. "I give you my blessing," she choked before she turned to leave, not wanting to see her sister die.

"Go and see her for the last time." Armin Arlert told Levi with a sad look on his face. "She doesn't have long now. Go and tell her…what you had never been able to." The blonde then looked at Levi. The years have hardened the once meek blonde, turning him into a veteran soldier. "If things have been different, I think that I would have welcomed you as my brother-in-law, Heichou."

The blonde then wrapped his arm around Mikasa's shoulders and led her down the hallway.

Levi hesitated for several moments before he entered the infirmary. The strong smell of blood and medicine immediately filled his nostrils. But for once, no thoughts of hygiene entered Levi's head as he immediately walked towards the sole white bed in the room, with the only occupant barely hanging onto life, blood soaked bandages visible around her arms, her torso and even her forehead.

"Hey Bright Eyes." Levi smiled the smile that he only reserved for Eren, using the nickname that only he uses. The Corporal pulled out a chair, dropping himself into it, holding Eren's bandaged hand. He barely restrained a cringe at how cold that Eren's hand feels.

Eren wheezed, apparently having difficulty breathing before she opened those beautiful blue-green eyes. No one else that Levi knew had eyes that colour, and he could stare into them all day and get mesmerised by them.

"…Le…vi…" Eren rasped, her eyes full of pain—most probably due to her injuries. "Did we…do it…? Did we…win…?"

"Yes we did, you troublesome brat." Levi's lips twitched, intertwining his fingers together with Eren's. "We won. We did it. Humanity has won our freedom."

Eren smiled. "That's…good…" she rasped. She then coughed, her frame cringing as the pain ripped through her body. "Just…when we'd won… I…really want to see…the ocean…with Armin…Mikasa…everyone… Even Levi…"

"I told you that I'll take you to see the ocean once we'd gained our freedom." Levi almost felt his heart breaking. He didn't even feel this distraught and heartbroken when Isabel and Farlan have died. "Don't make me a liar now, brat."

Eren smiled weakly at Levi. "I'm sorry…" she whispered, closing her fingers over Levi's. She coughed harshly, and Levi was almost alarmed to see the crimson liquid from the edges of Eren's lips. "I…really want to spend more time…together with everyone…" The light in her eyes is slowly dimming, and Levi has no idea if Eren can even see him now. "In another time and place, things might have been different. But no matter what, I will still choose to fall in love with you."

Levi closed his eyes briefly. "No matter where you are, I will always find you, Eren," he promised. "And then once more, I will ask you to marry me."

Levi tightened his hold on Eren's hand—almost as if doing so can help Eren to hang onto life for just a little longer. Eren smiled back at him weakly. "I'm…glad…that I met you…"

XXXXXX

Levi's eyes opened only to meet with the white surface of his bedroom ceiling even as his alarm clock went off. After a few moments, he got up and hit the snooze button before all was silent once more.

He had been getting lots of recurring dreams about his past life for the past several months now. While the faces of the people within those dreams were blurred in the beginning, they started to get clearer as time passed. And funnily enough, he wasn't the only one who had remembered everything from his past life.

Almost all his friends and comrades from his past life have turned up, all with their past memories intact.

The first whom he had met had been Farlan and Isabel. And this time around, Isabel had a legit reason to call him 'Big Bro' as both Farlan and Isabel were reincarnated as his younger twin siblings this time around. His earliest memory had been when he was four, and in the orphanage after his parents have died, and as he looked down at the sleeping faces of his three-year-old younger twin siblings, he instantly knew that it is them, and ironically enough, they knew that it is him.

Isabel and Farlan have died during their first expedition out of the walls, but for some reason, they still have their memories from their first life, though all three have carried the last name of Ackerman now. Isabel is still as clingy to him as before, and Farlan is still the same studious and intelligent boy that Levi had remembered. From the first day when they have remembered everything, the three siblings have stuck to each other like glue. Where one goes, the other two are never far behind.

The orphanage matrons have passed it off as a sibling thing, and had even moved Isabel into the small room that Levi and Farlan have shared with another boy after repeatedly finding Isabel sharing either Levi or Farlan's beds. The three siblings have never told anyone about their past lives after Farlan had convinced them not to, stating that others will think that they're crazy.

Most of the orphanage kids have left them alone after realising that none of the three wanted to play with them. Most of the time when they were in either the surroundings of the orphanage during playtime or even their room, Isabel and Farlan have curled up to Levi, wanting to learn more about Eren and what had happened to the world after they have died.

The three siblings have eventually left the orphanage not long after Levi had started junior high, and had used the inheritance from their parents to secure a small apartment not too far from where he is attending junior high in the town of Trost, with Levi eventually securing a part-time job as a courier.

Hanji and Erwin have turned up not too long after that, with Levi having met them when he had started junior high. Erwin is all smiles as usual and Hanji is as crazy as he'd remembered. From the first day when he'd started junior high, and had met them as his new classmates, Levi knew that it is them, and they knew that it is him.

Even as much as Levi is annoyed by Hanji's crazy outbursts, he had taken it in his stride, and his two closest friends were never far from him after that, even often helping to care for Isabel and Farlan when he is at work.

The rest of Levi's squad have turned up when they'd started their second year of junior high. And like before, every single one of them had practically idolised Levi. Thankfully however, Oluo doesn't try to imitate him so much anymore.

Petra was even happy to hear that Levi had eventually listened to his heart and admitted that he loved Eren, and was even in a relationship with her for two years until she'd died the last time. The rest of his squad was also happy to hear that, though they were of course upset and even a little ill when they'd heard just how Eren had died, and what had happened after they'd died during the 57th Expedition.

It is only with Levi's insistence that Petra, Gunther, Eld and Oluo have stopped calling him 'Heichou', and addressed him by his name, as they've been getting lots of strange looks from their classmates and teachers whenever someone heard them call Levi that. Hanji had nearly laughed herself into a coma when she'd heard a classmate of theirs wonder loudly to his friend if they have some kind of military kink going on.

Levi hadn't been amused.

Moblit had also turned up during their final year of junior high, having been a scholarship transfer student from another junior high school. Hanji was overjoyed to have her best friend and lover back—as the two were actually in a relationship with each other the last time until Moblit had died during the Final Battle protecting Hanji.

It sometimes made Levi ill at seeing Hanji and Moblit all over each other—just one step away from a full make-out session. Who knew that both Hanji and Moblit are extremists at PDA? Moblit had also introduced Levi to his new job as a barista at a coffeehouse that actually pays better than Levi's courier job, and also allows him to have more time to himself.

Isabel and Farlan were happy at knowing Levi's friends whom they have never met the last time around, and Isabel and Petra, being the only females in the group apart from Hanji have gotten on like a house on fire. Farlan had also gotten along quite well with Erwin, with both of them having long discussions about books and literature, much to everyone's amusement.

Most of the Survey Corps haven't shown up yet even by the time that Levi and his friends have started their first year of high school at Rose High School, and though Levi had never said anything, all his friends knew that he had been getting nervous and worried that none from the 104th Squad had showed up, especially Eren.

Being the scientist of the group, Hanji had even theorised during one of their study sessions at Levi's house that just as it had been for them, maybe the 104th Squad is in a different town. After all, that lot had been particularly close with each other, especially when all the shit with the Military Police had gone down after Pastor Nick was murdered the last time around, and when they have to rescue both Eren and Historia from the clutches of the Military Police.

Thus, it is with a heavy heart as Levi got ready for his first day as a junior in high school, his dreams of Eren's death still haunting his mind even as an excited Isabel had all but dragged Levi and Farlan by their hands to school. As Farlan and Isabel have both been a year his junior, they would be starting freshman year whilst Levi and his friends were in their junior year.

From his second year of junior high onwards, Levi and his friends have gotten a little more active in their school activities, and that hadn't changed even when they'd started high school. Petra is in the cheerleading club for some reason whilst Moblit and Hanji were both in the Science Club. Erwin on the other hand is in the Literature Club, with Gunther, Oluo and Eld joining the basketball club along with Levi.

There is even a good chance that Levi might be named vice-captain this year, as the current captain couldn't find anyone amongst the seniors good enough for the vice-captain position, and in their basketball club, their captain is also their coach. Hence, the vice-captain is needed to keep order and also to handle the administrative stuff of the club, as they do not have a manager.

"Do you think that she will ever appear?" Levi asked suddenly as they were currently in the middle of changing into their practice clothes, getting ready for morning practice. He looked at Eld, Gunther and Oluo who all looked extremely surprised at this sudden question. "Will Eren ever appear?"

His three friends didn't know what to say for several moments. "I'm sure that they will soon show up." Eld said at last. "I mean, all of us did, didn't we? Even your childhood friends whom none of us had ever met showed up. So I'm sure that Eren and her friends will show up soon."

The door to the changing room opened just then, and a member of the basketball club poked his head in. "Hey! Hurry up, you lot! Captain wants to introduce the new manager to us, and also to go through the details of our club recruitment exercise later in the week."

The four males in the room looked at each other, perplexed. "Manager?" Gunther echoed. "I mean, I know that we've been in need of one since last year, but with the high requirements needed, I didn't think that we will ever find one."

True enough, the current captain of the basketball club had been pretty particular about the criteria of the club's manager, with said manager needing to have the ability to draw up training menus and even devise strategies for their matches against rival teams. Due to the high requirements, none of the applicants thus far have pleased the captain, and not to mention that about half of the applicants have only applied to be close to all the boys in the basketball team, and doesn't even know half of what the manager is supposed to do.

"Let's go and find out." Levi said curtly, closing the door of his locker.

Despite their captain also being the coach, the basketball team is actually skilled enough to go to Nationals the previous year. Hence, even Levi is curious to know just who had captured the basketball captain's attention enough for him to appoint her as the manager.

The basketball captain, a tall senior with black hair by the name of Hayden was talking with a small petite girl that all have assumed to be a freshman. Hayden looked up the moment that Levi and his friends approached.

The rest of the team were already in their practice clothes, standing before the captain in a straight line, each of them eyeing the petite freshman that Hayden had been speaking to. Levi, Gunther, Eld and Oluo quickly took their places amongst the team and waited for Hayden to start speaking.

"There won't be much practice done this morning as we have the club recruitment drive to worry about this week." Hayden told the team, with the small freshman being partially hidden behind him. Levi frowned, as he could swear that he felt as if he should know her… "Levi, starting today, you'll be the vice-captain."

Levi was taken aback for several moments. Sure, he knew that it is probably coming, but it is still a surprise to hear it. Claps and cheers filled the gym not long after that, and Gunther smacked Levi on the back.

"Way to go!"

"We'll be counting on you, Vice-Cap!"

"Doesn't that mean that Ackerman will be Captain next year once Hayden graduates?"

Hayden cleared his throat loudly, and silence reigned once more. "Thank you," he said curtly. "Also, I'm sure that all of you have heard already, but starting today, we finally have a manager." He grinned triumphantly, and relief could also be seen in his posture.

"Bet you are glad that you can now focus on the training and not worry so much about other teams, Hayden." Levi said snidely, and Hayden's eye twitched, and the team laughed.

"A smart ass as ever, aren't you, Ackerman?" Hayden retorted. "I have half a mind to name Jinn as my vice-captain instead."

Eld raised his hands up in a surrender notion. "Please no."

Hayden shook his head. "The things that I put up with for the sake of this team," he sighed. He then looked over his shoulder. "Well, this bunch of crazies are the basketball team of Rose High School, unfortunately, and also last year's champions at the Nationals." He then looked at the basketball team before stepping aside to reveal a petite and small brunette nearly two heads shorter than he is.

Levi's eyes widened in surprise and shock as he stared back at equally surprised blue-green eyes. On either side of him, Gunter, Oluo and Eld stiffened in surprise and shock, staring at their new manager.

"This is our new manager." Hayden told them, oblivious of his juniors' inner turmoil. "Her name is Eren Jaeger, and she is a freshman in our school. Treat her well."

A/N: Is this too awkward for a beginning? I mean, I've seen tons of reincarnation stories, but not once have I seen one where Eren is a girl, so I thought that I want to write one. And yes, I know that in nearly all my stories, Levi is taller than Eren, but I always had a thing about guys that are shorter than myself, so I made Levi taller than Eren in my stories. Besides, writing a tiny Eren is fun as well!

Anyway, I hope that you like this story and chapter, and please read and review! Reviews give me inspiration to update!
