Author's Note: Hello! This is my first major fanfic EVER, so I hope it's good and people like it! I came up with the idea one night at work, actually. You know, when you're bored out of your mind you can come up with some of the best stuff you've ever thought of. I can, at least. :3

This fanfiction will contain Primarily OC's, but please don't let this scare you off. I know a lot of people don't like fanfictions with OC's (Me being one of them), but since I'm still new to the world of fanfiction, I found writing with my own characters was a lot easier than trying to get the personalities of all of Isayama's characters down perfect. Of course it will have Levi in it as a main character, and there will be a few guest appearances by other characters from the anime/manga (Not gonna spoil those for you just yet), but it is primarily OC's. I hope you guys don't mind. Not all of my stories will have OC's.

Also, I apologize if I accidentally switch between 'Scouting Legion' and 'Survey Corps'. Couldn't decide on which to call it (Ended up going with Scouting Legion, so if there's a few 'Survey Corps' in there, my bad)

Now, after an uncomfortably long Author's note, let's get into the story, shall we?

DISCLAIMER: Lucius and other OC's belong to me. Levi and Attack on Titan do not.

The Military Police; the king's personal lap dogs. Once upon a time they were respected and many young children looked up to them, one day hoping to join the ranks themselves. It was known that only the best of the best soldiers could make it in to the Police, and so trainees tried extra hard to work their way to the top of their graduating classes, many doing whatever it took just to get there.

Because of this, the Police were also known to be full of corrupt, backstabbing men and women as of late. Soldiers who had gone as far as to kill their comrades before graduation just to boost their placement by default; ones that joined the Police merely for the status and not for protecting the citizens and making sure everyone lived in peace in the inner wall. Some even found enjoyment in making regular citizens as miserable as possible.

During the depression in the Years 820-837, many people, even within the normally wealthy wall of Sina, lost their homes or couldn't afford to provide for their families. Taxes had been raised to insanely high levels and unemployment rose with it. Many resorted to stealing just to eat. Those who couldn't deal with the stress took an alternative route out: whether by gun to the head or knife to the throat or wrists. The latter was more common, guns being horded by the Military Police.

Members of the Police made it their mission to show up at the funerals of those who'd killed themselves and taunt the dead, right in front of their families, most times. They'd laugh at the homeless children, scrounging for scraps in alleyway dumpsters, occasionally flicking a coin or two at them, aiming directly for their heads. While hundreds of citizens suffered in poverty, they relished in riches, working directly under the king.

As for the king, he did nothing to stop the torment his people faced day in and day out by his subordinates. After all, he'd been the one to put them in the situation in the first place. Since the current king had taken the throne after the previous king- his father's- death, things had been getting worse and worse for anyone who wasn't born into nobility. The young king was greedy and only cared about himself, that much was obvious. Some even speculated he'd killed his own father to get to the throne sooner.

That speculation, of course, only made the Military Police's torment that much worse. They began to arrest people for treason, even if they'd done nothing or not said a word to suggest they would go against the king. Many innocent people were unjustly thrown in jail, some even killed. Blood soaked the streets these days, and, sadly, everyone had grown used to it.

In the year 823, Dmitri Ackerman, one of the Scouting Legion's best soldiers, was counted among those casualties. Many members of the Scouting Legion, especially the higher-ups, were being accused of treason simply because they were fighters for justice, and they knew the King and the Military Police were corrupt and unjust. Many escaped with their lives and freedom, because humanity couldn't afford not to have them fighting the Titans for them, but some were less fortunate. Dmitri had been hard-headed, and spoke his mind. He always said what he felt, no matter the consequence. Well, the consequence one fateful day when he'd called the king a 'Greedy, Shit-headed Pig', had been a bullet to the head, courtesy of an MP handgun. His blood had stained the streets, and his two young sons, that day.

Now, in the year 825, Dmitri's wife, Darline, was also under suspicion of treason. She'd lost most of her will to live when her husband had been killed, the only reason she hadn't gone off and killed herself or as many Military Police members as she could is she was the only one left to take care of their sons. The twin boys, now nine years old, had no other family. No aunts or uncles, no grandparents… nothing that she knew of at least. Her entire family was deceased and Dmitri had lost contact with his before she'd even met him. As far as either of them had known, they were all dead. She was all the two boys had left, and they were all she had left in the world. She swore she'd never leave their sides.

The three had gone in to hiding when they'd learned that Darline was being hunted down. They were currently all huddled together in the basement of an abandoned house on the outskirts of the city, while the MP rampaged through the nearby buildings looking for them. She knew time was growing shorter until they were eventually found, and her fear mounted, spreading to the boys sitting on either side of her, clinging to her shirt.

She felt them tremble, and soothingly ran her fingers through raven black hair. "Shh… Lucius, Levi… don't worry, everything will be fine. Momma won't let anything bad happen."

She admitted she maybe babied the two a bit. They were nine now, after all. They were growing in to little men right before her eyes. They'd stopped calling her 'mommy' or even 'momma' a few years ago, they insisted on doing everything for themselves, and they even sparred with the wooden swords their father had crafted and taught them to use before his death. But, they were her babies, and would still be her babies when they were full-grown adults.

She just hoped she got to see them get that old.

"Mom…?" Lucius spoke up to her left, peering up at her with ice-blue eyes. "Are the Police coming to get you, too…?"

Levi tensed up on her right, clutching her shirt tighter in his fist. She smiled lightly, rubbing the boy's back as she answered his brother's question. "Yes…. They are." She wouldn't lie to her sons, no matter how much she wanted to protect them. "But, don't worry… Nothing will ever tear me away from you two. Not even a Titan could separate us. Understand?"

Lucius nodded, mirroring his mother's smile. "Understand." He looked over to the other boy, who'd been silent up till now. "Understand, Levi?"

Levi didn't respond because, quite honestly, he didn't understand. How could his mother and brother be saying such things? He'd seen what the Police had done to his father. And now they were coming, with the intent to do the same to his mother. But the other two acted as if truly nothing bad would happen. If they were found, he knew exactly what would happen, and his chest tightened in fear because of it.

"Levi?" Lucius frowned, looking over at his brother. It wasn't normal for the other boy to be so quiet. In fact, Levi was usually the loudmouth of the two brothers. He'd definitely taken more after Dmitri, whereas Lucius was more like Darline in personality.

"Levi, dear, are you okay?" Darline frowned lightly at her younger son, running her fingers through his hair. Her only response was a nod, which wasn't sincere at all, but she decided not to pester him further about it. Besides, the sound of the front door of the house being kicked off its hinges a floor above them spurred them all into silence.

Having taken it upon herself to lock the basement door and blockade it with as many heavy items as she could find on the lower floor, Darline found she was a lot calmer than she ought to be. If the Police insisted on breaking through the barricade, she'd at least have enough time to help the twins get through the small window to the outside that they hid beneath.

Heavy footsteps sounded above them, causing dust from the basement ceiling to rain down. Lucius had gone back to hiding his face in his mother's chest, both boys trying to find some kind of comfort as the threat quite literally loomed over them.

Darline held the boys tightly, trying to soothe them. She whispered in a worried tone as the footsteps moved closer to where the door leading to the basement was. "It'll be okay, my loves… don't you worry, it will all be okay… nothing will happen to you, nothing will tear us apart…"

The door wiggled violently, the person on the other side of it trying to pry it open, only to find it locked. Muffled voices were heard, and more sets of footsteps headed towards the door.

Levi finally looked up at his mother, steel-grey eyes burning into hers. "Mom… they're going to try to break the door down…"

Just as he'd finished the sentence, a great jolt rattled the door and splintered the wood. Darline and the two boys jumped, hearts thudding in their chests.

"Shit…. Shit, shit!" Darline panicked, holding her sons tighter. "Lucius, Levi.. I'm going to hoist you two up to the window so you can run away, okay?"

Both boys looked up at her now as another jolt to the door caused the wood to splinter further.

"No, mom. We're not leaving you behind." Lucius frowned, clinging tightly to his mother.

"You said nothing would tear us apart." Levi added, and Darline felt her eyes stinging with tears.

"I know… I know I said that. And I meant it. But you two have to stay safe. Even if they throw me in jail, I'll still be with you. Maybe not physically, but I will be. Now come on." She pushed the two off of her, standing up and holding her hands out for them.

The boys refused yet again. Levi stood, crossing his arms over his chest as he glared at her, and Darline saw his father in him. "I'm not going to let them do to you what they did to dad."

Darline choked back a sob, her throat tightening at the mention of her husband's murder. Lucius stood and joined his brother, also crossing his arms over his own chest. The two were perfect mirrors of each other. "You two…"

With one last jolt, the door gave way and shattered into a dozen pieces. One surprised Military police lost her balance and stumbled into the blockade, successfully knocking it over and tumbling down the stairs along with it. She landed on the cement with a sickening 'crack' as her neck broke and the chairs and boxes Darline had pushed in front of the door landed on top of her.

The other two were a bit luckier and descended the stairs carefully. They drew their guns and aimed the moment they spotted their target. Darline's breath hitched in her throat and she threw her arms out to shield her sons.

"Don't worry Mrs. Ackerman", the older of the two remaining Police said calmly, aiming down the sights of his gun, which was pointed directly at her heart. "If you come with us quietly, your life will be spared and your boys will be put into nice foster homes and won't be hurt. We might even put some effort into finding a home that will take both of them."

"Fuck you!" Levi growled out from behind his mother's arm. Lucius stared wide-eyed at his brother, worried that the soldier might go back on the words he'd just spoken.

"Ahh, the little one's got some spunk, huh?!" Both Policemen laughed, and Darline looked over her shoulder at the small boy. "Levi, please… don't antagonize them. I promised nothing bad would happen to you two, but they won't hurt you if you don't tempt them!"

"Mom…" Young Levi Ackerman looked up at his mother, a feeling of dread weighing heavy on his chest. Despite that, he spoke the next words with such confidence that they could rattle any adult man. "I won't let them hurt you, no matter what. Dad said he'd always protect us, but since he's not here anymore, I have to."

His words touched her deeply, and her heart swelled with pride that this was her son. She was filled with new determination never to be separated from him or Lucius. Flinging her arms wide, she wrapped them both close to her chest, tears finally spilling down her cheeks. "Please!" she shouted to the Police behind her. "Please, don't take my babies away from me! I'd do anything!"

"We gotta take you in, ma'am. With your connection to Dmitri Ackerman, the King has determined that you're too dangerous to remain a free woman. We can't promise the cell you'll spend the rest of your days in will be comfortable, but if you come quietly, we can assure you that you won't be immediately sentenced to death."

The two men took a step towards the huddled three, one of them pulling a pair of cuffs off of his belt, the other still holding his gun aimed at the woman. As they got closer, Darline's cries not to separate her from her sons grew louder, more frantic; and the two boys in her arms trembled at the impending fate.

But they wouldn't settle for it. At least, Levi wouldn't. In a split second, he'd ducked under his mother's arm and was making a mad dash toward the approaching police. The man was caught off guard by the sheer speed the kid possessed, and barely even registered when he had grabbed hold of one of the hilts of his 3Dgear, snapped a blade into it and severed the cord that held the hilt to his belt all in one fluid movement. Before he knew it, his own weapon was being held to his throat.

"Make one move and I'll kill you!" The steeled determination in the young boy's eyes was enough to knock fear into the man's heart, and he raised his hands in defeat. He wasn't ready for his life to end. Let alone at the hands of a nine year old kid from the slums.

But his partner had other ideas. He swung the barrel of his gun away from Darline and pointed it at the boy. Upon seeing this, Darline gasped, a scream wrenching itself from her throat. "No! Don't hurt him!"

In her moment of weakness, Lucius also sprang into action. He rushed at the Policeman with the gun, barreling into his knees and knocking him off balance enough for them both to fall to the cement floor.

The gun went off. In the tense silence that followed, the woman could swear her heart skipped forty beats.

"LUCIUS!"

Her head swam when she thought maybe her elder son had been shot, but the jumble of limbs a pool of blood was forming around moved, and soon Lucius sat up. The soldier lay beneath him, lifeless.

"You…. You little shit!" The last remaining soldier shouted, drawing his other sword and turning to Levi, who stood motionless, stunned from what had gone down with his brother. The boy just barely managed to regain his composure in time to keep his head, ducking underneath the sweeping blade.

But the man was fast. Faster than the nine year old anticipated and he managed to cut the boy's arm, despite Levi's nimble dodging ability. Levi hissed, clutching the gash on his arm as the sleeve of his gray shirt was quickly stained red.

That was when Darline couldn't stand to just sit by anymore. She had to do something before one or both of her sons were killed. She willed her body into motion, pushing past the pain and fear that was threatening to eat her alive in order to protect her sons. They were all she had left in this world. She couldn't lose them. She wouldn't.

Sprinting to the fallen soldier's side, she grabbed one of the sword hilts from the gear hanging at his hips, and did as her son had done mere moments before; snapping a blade into the hilt and severing the cord that connected it to the rest of the gear, before turning on her heel to face the last man standing, who was still swinging wildly at her son. Levi stumbled backwards, tripping over a crack in the floor and falling back just in time to dodge another swing of the man's sword. He was getting lucky, but Darline knew it wouldn't last forever. She had to act now.

"Lucius! Take your brother and run! Get out of here!" She screamed over her shoulder, charging at the Military Police. She had been in the Scouting Legion herself for several years before becoming pregnant, and so was decent with the flexible blades commonly used by the military. But, she'd been out of commission for nearly ten years, and her skills were rusty. The man she faced was much more in practice, despite the Police being relatively lazy and never having to face combat with Titans. He blocked her attacks easily and returned with a few of his own, all swifter and more precisely aimed than Darline's were.

"Lucius, now!" She screamed again, noticing neither of the boys had moved. At the frantic tone now in her voice, however, Lucius darted over, grabbing Levi by the arm (And ignoring his brother's protests as his wound was squeezed), and dragged him up the stairs. They had to maneuver a bit around the fallen blockade and the body of the first dead soldier, but being young, small, and nimble; they were easily able to make it to the first floor of the abandoned building, and outside.

Sun greeted their eyes harshly, having been sensitized by spending so long in the dim-lit basement. Pausing briefly to catch their breath, Lucius looked around. The house they'd taken shelter in was in the poorer part of the city (Which was saying a lot because most of the city was poor), with dirt roads and all the brick buildings huddled close together, forming narrow alley ways. Of course, he and Levi had been through said alley ways thousands of times before, the home they'd grown up in being less than a mile from where they were. They could easily lose the bumbling Military Police among them, if the bastard managed to escape from their mother, that is.

Lucius tugged at his brother's sleeve again, noticing the other boy hesitated and looked back at the house.

"Come on, Levi, let's go."

"But… what about mom?"

"She'll be fine. That bastard doesn't stand a chance against her! She was in the Scouting Legion, same as dad, remember?"

"But…"

"But nothing! Come on now, let's-,"

But before Lucius could finish his sentence, a gunshot cracked through the air, causing both of them to jump. Lucius felt his blood run cold as the sound bounced between the enclosed walls of the other buildings, causing it to repeat over and over, getting quieter each time. He saw his brother tense up, knowing the other boy probably felt the same. It wasn't a good feeling. It was like a boulder in the pit of his stomach. His knees started shaking and he felt like he could pass out any second.

"L-Levi…. You don't think…"

He trailed off as loud footsteps were heard coming up the stairs from the inside of the house. Footsteps that were too loud to belong to a woman wearing flats. They belonged to a man, wearing boots.

Their fears were assured when a blonde head peeked out of the house, disheveled hair gleaming in the sunlight. The man had a smug look on his face when he saw the boys, and exited the building the rest of the way. His uniform was dirty (Probably from climbing over the mess at the bottom of the stairs), and cut in a few places, blood staining the white pants red and the brown jacket nearly black He smirked, raising the barrel of his shotgun and pointing it at Levi's head, then Lucius'.

"Come on now, kids. If you comply, I'll make sure you two don't end up in a detention center."

It was then the boys both knew: Their mother was dead. Lucius shook uncontrollably from fear. Levi shook, though for a completely different reason. Uncontrollable rage. All he could think about was killing the man in front of them. He wanted to see the man choke on his own blood after his throat had been slit. He wanted the entire Military Police to suffer as they'd made everyone else suffer.

He hated them all. But this man in front of him was the worst in his eyes. This man had killed his mother. He'd be the first to die.

Still wielding the stolen sword, Levi charged at him.

Lucius' head spun when he saw his brother running at the Military Police, brandishing the sword. "No, Levi! What are you doing?!"

"You've got some guts, kid. I guess you want to join your parents, huh?" The man pulled the trigger, and the ground exploded mere centimeters in front of Levi's foot. It didn't slow him down. He was dead set on making this man suffer a horrible death, and he wouldn't stop until he'd accomplished that.

Tossing the rifle, which was now out of ammunition, aside, the Military Police grabbed the hilt that hadn't been severed from his gear and snapped a blade into it, meeting the strike that Levi sent his way. The kid was relentless. As soon as his sword bounced off the other, he was swinging it again, and again. The man dodged and parried, barely able to keep up with the incredible speed the nine year old had.

'How the hell is a kid so good with a blade?!' he screamed in his mind, trying to get his own attacks in, but as soon as he went to try and swing at the kid, he had to maneuver the sword back in front of his body to block again.

It was then he remembered who the kid's father was. Dmitri Ackerman had been one of the strongest soldiers in the Scouting Legion. There was no doubt he'd trained both of his sons in combat before his death.

And then something hit him. Literally hit him. It was small and hard, and bounced directly off of his forehead. It didn't hurt, per say, but it did distract him enough to count.

Levi swung the blade at the man's stomach, and this time it wasn't met with the resistance of another sword. There was a tense silence for a moment before he realized what had happened. The warm spray of a red substance that coated his shirt and skin. The squishing noises of whatever was inside the man as it spilled out onto the dirt. The startled gasp of the Military Police as he came to the same realization that Levi did, before the lights dimmed in his eyes and he collapsed to the ground along with his innards.

He'd just killed the man.

Shaking lightly, Levi looked down at the sword in his hands. It was stained with blood. His hands were, as well. Everything was. His shirt, his pants… he even felt it on his face. It was the most sickening feeling ever. He wanted it gone. He wanted any evidence of what had just happened to disappear from the face of the planet. He didn't want to believe he'd killed a man, even though before it had happened he'd wished for nothing more than that man's death.

He deserved it, after all, didn't he? He'd killed Levi's and Lucius' mother. The man deserved to die. Levi had wanted to kill him. But… now that he'd actually committed the deed, he felt sick to his stomach. And he wanted to scrub at his blood-stained skin until it peeled off and he could feel clean again.

"Levi…?"

Turning to the sound of the voice, he saw his brother standing a few feet away from him, a few pebbles still clutched in his hands. So that's what had distracted the man so much it lead to his demise…

"Lucius…. I….I killed him…"

Lucius nodded, dropping the rocks in his hands and pulling his younger brother into a hug. Levi squirmed, trying to pull away.

"Stop it. I'm covered in his blood, you'll get filthy!"

"I don't care… as long as you're okay, and the man that killed our mom is dead, I don't care if I get the blood of a million members of the Police on me." He pulled away, giving the other boy a comforting smile. "Everything's gonna be okay, Levi. Understand?"

Levi's mouth dropped open a little, grey eyes widening before he had to squint against the sting of tears. 'Understand' was something they and their mother had always done. She would tell them something and then ask 'Understand?' Instead of answering 'yes', or 'understood', Levi and Lucius would always answer with the grammatically incorrect response of 'Understand'. It had been their thing. And having Lucius ask him that just reminded him that they'd never see their mother again. She was…. Gone.

He nodded, gritting his teeth to bite back the tears and responded.

"Understand…"

Lucius smiled wider. Levi noticed he had red stains on him, transferred from him by the hug. The older boy didn't seem bothered in the least by it, though. All Levi wanted to do was find the nearest source of water, whether it be a faucet or a puddle, and get the blood off of himself.

"Let's go." Lucius said, nodding his head in the direction opposite of the house they'd been hiding in with their mother. He contemplated going back to the basement to see their mom one last time, but didn't think his brother was stable enough at the moment. Levi was still shaking like a leaf, and he gripped the hilt of the bloodied blade so tightly his knuckles were white. He also had a hollow look in his eyes that told Lucius it was better not to do anything else to rattle him just now. So he took Levi's free hand in his and started away from the building.

Whoo! First chapter down. Many more to come. Let me know if you liked it by leaving a review. I'd like to hear what you guys think!
