I came to the idea a while ago about if Levi had an older sister

For the sake of age range I made her a year older than Levi; making her 36

I tried to make her opposite to Levi and yet similar in some ways

Levi stood outside Erwin's office quietly; he had been called to see him after the fall of his squad. He was only grateful that Oluo and Petra were given nice send-offs at the funeral. For their sake if not for the rest of those who he cared for; He would see to the demise of the titans. So that way their deaths would not have been in vain.

Suddenly the door opened and Mike stood at the doorway "You may come in now" he said bluntly. With that Levi entered and Mike exited; as to give them some alone time to talk in privacy.

Levi stood at the end of the room near the door; Erwin was sat as his desk quietly his elbows leaned on the desk were his chin rested on his hands. He had a cold, stern expression; but his eyes were filled with complexity.

"Levi I cannot begin to understand what complexities are surrounding your mind right now. I only hope in time you're pain begins to ease" Erwin said calmly but his voice was filled with concern.

Of all the losses they had suffered trying to beat the titans; this had been the most personal to Levi. His team had been like his family; and he had to watch helplessly as they were crushed before him.

Levi frowned and clicked his teeth "Is that all you called me here for? To remind me of the loss of my comrades?" he snapped sharply. He did need time to heal; he was human after all. However he was not like Eren and his friends; he was used to seeing bloodshed and death. However he was still hurting but was good at not letting it show.

Erwin shook his head slowly "No; that was never my intention. The thing is we have decided to bring in extra hands to aid after the loss the female titan caused" he explained. The loss they had suffered under the female titan attack had been great. They didn't have enough recruits to fight the titans as it was. The fact that they needed further training didn't help either.

Levi raised his eyebrow "You mean the 105th squad? I mean while most of them show promise. They have nowhere near the experience needed right now" he stated bluntly.

The top 2 students in the class were Reiner Braun and Mikasa Ackerman; followed by Annie Leonhart and Jean Kirstein. With enough training and further enhancement of their current skills; they could become the new prodigies of their age and era. They just needed their skills tapping into and taken advantage of instead of going to waste.

Eren was talented and showed promise; however he had weak fighting stance and tended to let his anger get in the way of his concentration. However his titan form proved most useful to their efforts. But he needed to combine those skill in order to be at his best; as of right now they worked as separate entities.

Connie Springer and Sasha Braus were talented; but tended to slack off sometimes. During their training years they tended to mess around like idiots. Their skills had a long way to go for what it was worth. But in time they would become skilled cadets; but that time was going to be way off.

As for Armin; he was lacking in the physical strength needed as a soldier. However he had above average intellect which was surprising for his age. However Hange had taken a liking to him and had offered to make him her assistant. While he would not partake in being a lab rat; he would assist in her experiments in the future.

Erwin sighed heavily; this was going to get interesting. He had looked up personal information on Levi and decided now was a better time than any to bring in help. "Not exactly Levi; I brought in someone a bit more skilled. Someone who will be able to help out when you are detained" Erwin explained awkwardly.

He had no idea of what kind of relationship Levi had with his sister; when he first met her he was stunned they were even related. However she was none the less one of them; and a valuable asset to the team.

Levi raised his eyebrow; if it wasn't one of the newbie recruits then who the hell did he bring in? He contemplated his memories and thoughts for a while. Suddenly he realized who Erwin was talking about; his calm expression became more annoyed and scary.

"Erwin...this had better be a fucking joke" Levi snapped sharply. He didn't exactly hate his sister; in fact they had quite a healthy relationship. They did have similar personalities; only she tended to tease him and smiled quite often.

Erwin sighed heavily "I know this seems problematic for you Levi. But we need the best we can get right now. Next to you she is the most experienced fighter and can handle Eren as best as you can" he explained firmly.

Levi clicked his teeth "Whatever; You only called for her because you find it funny how she patronizes me" he scowled bitterly. He had given Levi some bare details on their past family life; while also going over her files together.

"Well you had best be on your best behaviour; she's on her way now" Erwin explained firmly. He had asked Hange to bring her over so they could be introduced. He knew she was secretly loving every minute of this; and truthfully so was he.

"YOU WHAT?!" Levi yelled angrily. Was Erwin doing this intentionally to test his nerves? Because it was bloody well working; he was seriously mad.

Eventually there was a knock at the door and Levi stiffened. He was barely containing his anger right now. How dare Erwin bring in his sister without consulting him at all?

"Yes?" Erwin responded bluntly. He hoped Levi wouldn't do anything rash; he didn't want anything breaking. He could take this elsewhere later and beat up a training dummy.

"It's Hange; I brought the new Lieutenant" Hange explained nervously. Working beside Levi she had learned how scary his temper would be. She could practically smell his rage through the door.

"YOU MADE HER LIEUTENANT?!" Levi raged furiously. First they bring her without his knowledge or consulting; now he was learning they would be working together?!

Didn't she live with her husband and work for a separate part of the core? Why the hell was she being transferred here? I mean he knew the lack of his team was great but why bring in his sister of all people?

He was going to chew out Erwin and Hange for this later. He knew that despite the seriousness they loved every second of this. The fact that he had no control over this situation angered him even more.

Erwin breathed in heavily; this was not going to go down well. He hoped that Levi would get violent; he had worked with the shorter man long enough to know what he was like. Some days were harder than others; that was for damn sure.

A young woman in her mid thirties around Levi's age entered the room. Like her brother she was very youthful for her age and didn't look her biological age. She had a curvy but well built body from years of training. She had large breasts that were held firmly by the corset she wore under her clothes. She found them to be far superior to bras and were easier to wear. Given proper training they caused fewer problems too.

She had steely greyish blue eyes like her brother that were as piercing as his. However compared to Levi's bitter rage her eyes were more gentle yet dominant. Her hair was black like Levi's only hers was cut in an above shoulder bob with a side parting cut over her forehead. Despite the shorter hairstyle and difference in fringe; people might barely of mistaken her for an older Mikasa.

Erwin raised his head from his hands "Lieutenant Ackerman I presume?" He asked firmly. They really did look alike; and they looked impossible for their age. If you covered their faces their eyes screamed that of a 20-odd year old.

The woman thumped her hand to her chest respectively "Yes sir; Lieutenant Evelyn Ackerman sir. I look forward to aiding my skills to destroying the titans" she said solemnly her eyes hard.

She took her skills and training from her younger years very seriously. Even after marrying her ex husband she still trained her body and her skills came as naturally as ever to her. If given the chance she could easily take down someone bigger than her.

Erwin smiled "I see; are you up to date with everything about or current situation?" he asked calmly. He knew Hange had given her details on the way here; as well as asking personal information for records. However he wasn't aware yet of what kind of data he would find once he read her files.

Levi's eyes flashed with pain; the fact that everyone would be talking about his loss would become irritating. He was in no mood to talk about it right now or share his feelings.

Eve's eyes became pained but her expression remained solemn "I have indeed sir. I cannot imagine my brothers feelings right now; but I will respect them by not prying until he is ready to speak" she said firmly.

While she cared for her younger brother and teasing him. She was also very considerate of his feelings as a person. She knew her limits to joke and knew that he needed space and support more than anything.

Levi flashed a grateful smile; he had always loved how his sister respected some form of his privacy. She may have teased him but she knew when to never pry into his business if he didn't wish for her to. It was one of her many redeeming qualities next to her less favoured ones of his opinion.

Erwin's gaze sharpened "I presume you are also aware about the trainee Eren Yeager. The boy that can shift into a titan" he said sternly. Eren was the secret weapon of the survey core and used to destroy the titans. However while his abilities weren't limited; but there were times a titan was just a bit stronger than him.

Given the loss of Levi's entire team who were of the most skilled cadets; they had lost a lot of good fighters. Meaning that apart from Mikasa; they didn't have as naturally skilled scouts.

Eve nodded "Yes sir. As far as I am aware he is being kept watch over by my brother. If he turns on us or betrays us we have the ability to slay him" she said sharply.

She had been given the information on the way here by Hange. Mainly it was filled with the nerdy scout going on about how amazing Eren's body was. But she managed to get the proper information eventually.

In truth Eve was quite amazed by this; for a prepubescent boy to be able to wield such power. She couldn't help but wonder if it was genetic or maybe it had been dormant and awakened by something.

Erwin smiled "Correct; but its only for precaution as he had little control upon his first transformation. I presume Hange gave you all the details on the way here" he said contently.

Eve stiffened and looked away; she had given her the information needed among other things. She had also gotten very touchy feely when she learned about her being Levi's older sister. Granted she was older by a year but she was still Levi's sister. Levi had been an unexpected baby but the pregnancy had been one of much joy to their mother.

"Y...Yes sir..." she said awkwardly. While in the carriage she had almost been groped, face handled and bombarded with awkward questions. She had come close to kicking her in the face with her boot.

Erwin gave a confused look "Did Hange do something to you?" he questioned curiously. He knew she came across as scary; but she was truly a good person when needed be.

Eve blushed a little and coughed awkwardly "You're...Your squad leader is very...that is...very hands on so to say" she explained awkwardly. She had never met a person like Hange before. So obsessed with learning every little thing about her in just one second; she had felt like she was being interrogated.

Erwin blinked as did Levi before eventually clicking. They had worked with Hange long enough to know what she was like. Her desire to learn new information knew no bounds. Even if she had just barely met that person she would become very forward and touchy feely.

Erwin smiled awkwardly "I see. I'm sorry your introduction to her had to start so awkwardly. I assure you Hange means well but she does sometimes get a bit excited about meeting new people" he explained.

Levi frowned and clicked his teeth "Shitty glasses really needs to learn her limits" he muttered crossly. She had only just met his sister and already she was getting all touchy feely with her. She really needed to learn when something was not appropriate.

"She seems nice but I just hope that such matters aren't repeated" Eve asked politely her tone hopeful. While she was keeping herself calm remembering the subject; she mentally wanted to break his desk into bits.

She would most likely snap and attack Hange if she got too personal and grabby again. Even she had her limits as a human being. The idea of someone she barely knew getting touchy feely annoyed her.

Erwin nodded "Levi will have a word with her later. Make sure she knows your discomfort" he said kindly. God this conversation was going to be awkward later on; having to explain to Hange how perverted she came across.

He knew that Hange and Levi were close friends; but even they had their arguments now and again. But he always made sure to let her know when enough was enough and to back off.

Eve smiled gratefully "Thanks; but just don't be too harsh on her. It was just more uncomfortable than anything" she admitted quietly.

While she was not hoping for it to ever happen again; she had been more embarrassed about it than angry. If so then she would have to get violent even if she wasn't fond of hurting her fellow recruits.

"I can't promise anything" Erwin chuckled nervously. Even if you gave him orders Levi followed his own self interest not the opinions or commands of others. He followed the beat of his own drum; not the instructions given to him.

Eve gave an awkward smile but was mentally angry; she knew of all the people Levi could never stand against it was her. Even as small children he could never say no to her. While he was feared by most of his other recruits; he was scared to the bone of her.

Being an ex Yankee she had quite the violent temper and a dark side to her personality; One that even scared the likes of Levi who was one of the coldest current members on the core.

Now and again she was prone to violent and harmful outbursts should someone important to her be threatened. While they had gotten less frequent as she got older; they got worse as did her temper and they always made a lasting impact. If she warned Levi enough not to do anything to Hange he would do it. He knew better than to cross his older sister given her temper.

"If you don't mind me asking sir; where will I be stationed? I'm already expecting it to be barracks of course" Eve asked curiously. It was one the few things she hadn't been told about on the way here.

She used to live with her husband within the walls quite happily. However after the fall of the walls he was crushed under a large piece of stone impaling him. After that day she lost the ability to cry even when heartbroken.

Erwin blinked then realized she hadn't been told about where she would be staying. Considering they were stationed at the castle with Eren locked in the dungeon; she would get her own room here.

"Levi will take you to your room. We have already put your things in there and you can relax after your journey" Erwin explained politely. How had Hange managed to miss telling her something so simple?

Once she had settled and relaxed a little; the plan was to introduce her to Eren. They would both be in charge of keeping an eye on him. Her job was to kill Eren also if he lost control and tried attacking humans instead of titans.

Due to the fact that Levi may sometimes be detained, busy or separated from their new group; chances could not be taken. The only person who was capable of rivalling Levi's skill next to Mikasa was his sister.

Eve smiled with a sense of relief; she had done enough travelling for now. To be able to relax for a short while on a soft bed was comforting to hear. "I see; is there anything else I need to know about. Or am I to be excused sir?" she asked politely her tone hinting hopefulness.

Erwin smiled "No that is all lieutenant; you may go now" he said firmly and raised his hand to the door. He had paperwork to deal with and a long lecture about inappropriate behaviour to give to Hange.

Eve nodded and bowed politely then turned to walk out the door. As she reached it Levi followed quietly from behind closing the door behind them. As they reached outside Levi clicked his teeth crossly his frown he had been holding back growing.

Did Erwin get a kick out of mocking him like this? Fucking superior old goat; he would get his. While he respected the older man; he pushed his limits and boundaries way too much, way too often.

As he did so his sister smirked cheekily her grayish blue eyes lighting up with amusement. Even as an adult Levi still acted like a child sometimes which she found amusing. God he really hadn't changed in all these years; it was both cute and annoying.

Levi shot her an angry glare; she was enjoying this too much "Something funny Evelyn Onee-san?" he asked darkly his eyes flashing with anger. While he respected her as an individual; she did things that pissed him off greatly including her teasing attitude around him sometimes.

Eve peered at him quietly still smirking "Still as sulky as ever Levi Otouto-san" she teased patronizingly. He was still sulky, moody and short tempered as always; he had been like that ever since he was a child.

Levi stiffened at the nickname and frowned; she still patronized him even when he was a grown ass adult. He thought a person would have dropped such things a long time ago.

"Hiding your true colours from Erwin until necessary eh Onee-chan?" he snapped in annoyance. She liked to remain quiet and keep her temper at bay until her buttons were pressed to the limit. Then all hell broke loose and all you could do was pray and apologize for what you had done.

Eve frowned and yanked his ear hard causing the latter to cry out in pain. She hadn't done this since they were teenagers. But it seemed that he needed to be taught another lesson about respecting your elders.

"You've got a lot of nerve getting mouthy with me Levi. You've always been a mouthy shit since you were a kid" she growled sharply. Levi hadn't started swearing until he was at least 18 and by then was legally an adult. However it hadn't stopped his sister or mother from punishing him for hid bad mouth.

Levi glared at her "Guess I got it from you eh Onee-chan?" he mocked in a mischievous tone. To this day he would never back down in an argument or fight with her unless he felt she had won. He was old enough and strong enough to stand up to her compared to back then.

Eve's glance sharpened into a glare and she twisted it harder causing his yell to turn into a high pitched yelp. He really needed to fix that attitude of his or he would never get married to anyone.

"You should know better than to speak to me like that Levi. You're not too old to get your ass kicked" she warned. When she meant ass kicked she didn't mean beating him in a fight. She meant a literal boot up the ass causing him to be so sore he wouldn't sit for weeks.

Levi stiffened and felt himself shudder; one time as kids she kicked his ass so hard it hurt to take a shit; God the painful memories. He would say "You wouldn't dare" but he knew she would.

Eve smiled menacingly "You going to behave now Otouto-san?" she threatened darkly. She was in no mood to deal with Levi's shit right now. She had been groped, pestered, investigated, transferred and lost her husband within a short period of a month. She was in no mood to be fucked with and especially little tolerance for Levi's shit.

Levi grimaced at the fact he was weakened by his sister's authority over him. But he knew about her colourful past and how much scarier she was than him. It was one of the other reasons he respected her.

He relented sighing angrily but gave into his sisters wishes "Yes" he muttered crossly. God he was glad Hange wasn't here to see this. She would tease the living hell out of him for being weak against his older sister.

Eve perked up and released Levi's ear causing him to cry in relief. His ear throbbed with pain and it would hurt for a while. That would teach him not to get lippy with her in a hurry.

"You know better than to challenge me" she teased cheekily her tone patronizing. While Levi had grown stronger and was a respected soldier; he was weak to his big sisters authority.

Levi stood where he was and watched his sister walk ahead of him. She was a beautiful, strong and powerful woman; but she didn't half annoy him sometimes. "I'm gonna kick Erwin's ass for this" he muttered crossly to himself. His life was going to be a living hell from now on.
