Knives. Knives can be used for all sorts of activities, ranging from preparing a scrumptious meal to murder. They are viewed as simple equipment for the 'innocent' whose hands are clean from bloodshed. However, they are also viewed as weapons of torture more than defence to peculiar types of people. One clan in particular was obligated to view it as the latter—the murderous one. That clan was the infamous Ackermans.

The Ackermans were masked villains that roamed the Underground district, staining their hands with blood for others who were willing to pay the price, but unwilling to commit the deed. From time to time, they would venture the surface, hiding in the alleyways as they proceeded with their business. Although they were bold and strong, they would often refuse any task that required too much involvement with royalty.

Many wonder the history of the Ackermans, however, none dared seek the answer. They were known for being monstrous after all. Little was really known about them. And considering that they were masked, it wasn't easy to identify them either. The innocent bread shop owner across the street could be an Ackerman, and no one would know. Many called them cowards for this reason, and yet, ironically, some of that many had probably sought out help from them.

Though, some time ago, the Ackermans began to be severely wiped out. Some say it was a disease that broke out that they were susceptible to, others say that the late King finally decided to actually take action against them. Yet, it was odd how the infamous clan—known for their physical abilities, along with their manipulations and such—were quick to be defeated.

At least, most of them were. There were just a few Ackermans left that no one could catch. To everyone's knowing, there were three left. No one knew their names, no one knew their faces. But everyone knew that they better rid them quickly in order to attain peace within the kingdom—at least, that's what the late King said.

That same King had passed away, along with his wife. The reasons for their death was unknown to commoners, and even to most of the royal and elite guards. But that didn't matter, there was an heir to the throne—Eren Jaeger—who was still alive and well. And when he'd finally turn twenty, the throne was all his.

As for the Ackermans, or at least what remained of them, they couldn't care less about royalty… at least two of them seemed very disinterested. For years ever since the 'Ackerman cleansing' (as what people called their wipe-out.), they had continued their lives as per 'normal'—committing crimes in place of those who feared to dirty their hands. It was ironic, how their supposed loyal customers would turn against them, supporting the cleansing of them, and yet come crawling to them, beseeching them to kill someone because they were too cowardly to.

It didn't matter. That was how life always was for them.

"Do we have any jobs today? I rather… finish it off quickly." A raven asked, as she glanced over to her brother who was sharpening a knife. "Yes we do, in a while. I take it that you already know the background of the situation?" He had responded. The way they talked about killing in such a casual way was nothing new, it was all they knew.

"Yeah… is he coming back today?"

"Most likely. Kenny finishes his job with no delays. Although, I wish he would be late. His presence is shitty."

"You know, he's our boss, you sho—"

"And?" The older of the two asked in a snide manner.

Mikasa heaved a heavy sigh, sometimes she wondered how her older brother could be so open about his resentment towards their maniacal Uncle. While she shared similar sentiments towards him, she would more often bite back her tongue if he was in a sour mood. Perhaps that stem from the fact she was a little more terrified of him than Levi, for reasons she rather not recall at the moment. "And," She continued, "You know what happens if we disrespect him in front of his face."

"Yeah, he makes us spill more blood, commit more crimes than necessary. Riskier crimes. Amazing, isn't he? Did I forget to mention he tried to kill us before?" Levi scoffed sarcastically, before he lifted his knife, examining it meticulously to see if it was sharp enough. Their relationship with their Uncle wasn't always this bitter, but ever since their life took a darker turn, and with Mikasa having issues with her bloodlust, Kenny changed. He became stricter, and sometimes more violent during his trainings with Mikasa due to her lack of control. Maybe that's why she feared him more than Levi.

Mikasa only responded with a simple nod, muttering something inaudible before turning away from her brother and made her way to check on her own weapons. Catching a glance of her, Levi noticed a tinge of pain stinging her.

It was always this way. Behind the monotonous look that they wore and had acted as a mask, was an infinite amount of pain and guilt that they both gradually learnt to supress. In the first place, who with a sane mind would want to kill? At least, not them. Although, even with all the guilt they felt, they continued their journey on the bloody path set for them since birth, knowing that deterring away from it was not an option.

"You alright?" Levi managed to ask, setting down his knife and approached his sister. "What do you think?" She laughed weakly, responding with a rather rhetorical, bitter question before turning to face her brother.

Her monotonous look remained, her guard was still up for the most part. Yet, Levi noticed just a little bit of her vulnerability slipping out. A vulnerability that only he was permitted to see. He was the only one Mikasa could fully trust, the same went for Levi with her. They only had each other in this hell after all. As for Kenny, he was more of a 'boss' to them rather than a family member.

"…It's not a solo mission." He assured. Comforting wasn't usually his forte, and while he had taken countless lives, there was still room left for him to show some form of empathy to her. "I'll be there just in case. Kenny knows better to assign you to one again." Levi sighed, "Has your control… improved?"

Little was known about the history of the Ackerman Clan, it was practically unknown to everyone on how the Ackermans had impeccable strength and how they were able to carry out such crimes in a ruthless way. Even Levi and Mikasa knew very little of their family's history thanks to Kenny, who kept information about their heritage to a minimum for whatever reason he refused to tell.

One thing both of them knew very well, however, was the bloodlust that hid in their veins, waiting to bite.

Levi managed to gain control of it… at least, more than Mikasa. The last time he had let his bloodlust get the best of him was years ago. Even so, the suppression of such corrupted desires was more difficult than it looked.

Levi still recalled how disastrous her first solo mission turned out. She was meant to kill one person, just one. But as if something had snapped in her, she went on a rampage, and started a well-known massacre in the underground district. While Kenny had explained to her before that it was just some form of 'puberty' Ackermans went through, it didn't exactly explain why her bloodlust unveiled itself at a much earlier age than the expected age of sixteen.

Fortunately, Levi had later came to her rescue, managing to tame the monster within her before snatching her back to the grimness of the shadows to hide. He knew this massacre wouldn't spread all too much nor would it be made public—considering the royalty and surface dwellers couldn't care less about the ones living beneath, they only seemed to ever show concern for the underground when it involved some illegal business that could benefit and profit them. Of course, such connections were not made known public.

In a way, it was a good thing since Ackermans—like most criminals— didn't like the spotlight all too much. And the last thing Levi wanted was an investigation to be conducted by the elite royal guards who were much more meticulous and a hassle to deal with as compared to the regular guards.

Although the underground was known for its several, countless and daily brutal and horrid crimes, there were still innocent people residing there who wished to lead a peaceful life—but their social and economic status said otherwise.

Levi still remembered the look she had when he removed her mask once they reached the safety of their hideout—their home. Her obsidian orbs had shifted into a darker shade, and although it was hard to see her pupils, he swore they were in slits. Was that how he looked like when his bloodlust got to him too?

He wasn't sure, nor could he care. He was more concerned for Mikasa—who was only thirteen during then, during her first bloodlust outbreak.

"I don't get it! Why must we kill?!" She once screamed before shedding tears. Levi tried his best to comfort her, but he didn't answer her question. He couldn't, because he didn't know the exact answer himself. He just knew that there was no escape from killing nor the bloodlust that had the possibility of consuming them whole if not supressed appropriately. He remembered his first 'outbreak' and how he failed to control it, it was a chilling memory, at the same time he recalled the wicked and disgusting satisfaction he felt from watching red liquid ooze from the corpses. Since then, he began to discipline himself to control it better— but he knew that wouldn't be enough to permanently prevent future outbreaks, even he hadn't had an outbreak for quite a long while. Although, there were times where he didn't mind succumbing to become a monster, but there were still… things and people that held his sanity together.

Unfortunately, unlike him, Mikasa struggled much more in controlling and containing.

After Kenny found out about Mikasa's little incident, while he was caught off guard by the abnormally early outbreak, he initially decided to shrug it off, thinking nothing too much of it. He assumed, like Levi, after her first 'outbreak', she would be able to control it better.

He sent her to another solo mission, and the results were the same—a bloody mess that drew in too much unwanted attention. He shrugged it off again, sending her off for another solo mission on and on again receiving the same results until he came to the conclusion that Mikasa had… issues. Long story short, because he wanted to keep a low profile and didn't want any unnecessary attention or future potential customers to be slaughtered, he became stricter with her and forbade her to go on any solo missions. For the most part, she was accompanied by Levi.

After all, it would just take one mess up from an Ackerman who lacked senses and control when the bloodlust took over to reveal everything, their identity included. At least with Levi to watch over her during their missions, the chances of her going completely out of spiral was lower since he would be there to bring her back to her senses. There was something about Levi that made Mikasa calm, perhaps it was because he was the only one who she could actually call family.

Back in the present, Mikasa eyes trailed towards her palms, where she envisioned blood stained on them, again. "I…" She paused, unsure of how to answer his question and instead, responded with one; albeit it seemed more directed at herself than him. "Why can't I control it…?" She mumbled. Ever since Mikasa found out about how uncontrollable her bloodlust was, she had given up any hopes of leading a normal life. When her emotions spiralled, anything trivial can trigger her bloodlust to take action, and the last thing she wanted to do was harm any more lives than the ones she was appointed to kill. At least now, after years of training and discipline, she had gotten slightly better at controlling it, though she still had those moments where she came close to starting another massacre.

"Mikasa." Levi whispered, before gripping her shoulder in a reassuring manner. "Don't worry… I won't allow things to get out of hand."

Mikasa flashed a little smile, "Thank you." She murmured before standing up. "I just wish I could control it as well as you do." She continued silently, speaking too quiet for Levi's ears to catch. But before he could ask her to repeat her words, she grabbed both their masks resting on the table. She tossed Levi his, before wearing hers. "Let's get this done and over with."

Before anything else, Mikasa grabbed her cloak and necessary weapons before leaving immediately, lurking in the shadows. Levi sighed, following after swiftly.


The lives that the Ackermans took weren't necessarily innocent ones. They never were, and according to what Kenny told them, the Ackermans never took the lives of the innocent, unless their bloodlust got the best of them. Normally, after an Ackerman's first bloodlust-takeover, they'd be quick to control and adapt on their next kill. But that wasn't the case for Mikasa. He never explained why; and maybe it was because he didn't have one. She was the first abnormal case after all.

Before Mikasa's first bloodlust breakout, she had done all her kills swiftly, no flaws whatsoever. Kenny was amused at how quick she learnt to kill with skill, she was a fast learner just like Levi, if not, faster. That amusement didn't last long after he realised Mikasa's lack of control when it came to her bloodlust, but rather than disappointed he was more agitated and frustrated.

The lives that Ackermans often took were beyond corruption, at least that's what Kenny claimed. But at this point, both Mikasa and Levi were uncertain if he was just spouting flat lies—but even if he did, what could they do?

Levi had once thought about escaping Kenny's control, but he had to grudgingly admit, Kenny was a formidable opponent who wouldn't let them leave so easily, especially when they were the last known remaining bloodline of the Ackermans. The last thing Levi wanted was to endanger his sister's life if they were to get caught escaping.

Killing Kenny was an option, but that was anything but easy. Sure, both Levi and Mikasa were strong. But Levi knew even with an unfair fight with two against one, they probably stood no chance against him, their mentor who had taught everything they knew, but not everything he knew.

"Levi, we're here." Mikasa whispered.

The lives the Ackermans took weren't necessarily innocent ones. But, in this life, were there anyone truly pure? Humans are humans, they are bound to commit a crime or a sin, whether it be trivial or not. So, doesn't that mean no one's innocent?

The Ackermans can and will take anyone's life, is what outsiders said, and it's what Levi unfortunately and reluctantly had to agree.

"I'll deliver the kill. You just stay on a look-out." Levi murmured.

That night, they were sent to kill the guy who owned a well-known weaponry shop that Levi would often purchase his equipment from, at a very unreasonable price, and his crimes that he committed were unreasonable as well.

"But you delivered the kill last time… I know you don't like me dirtying my hands. I know you want to protect me. But it's only fair, I'm not little anymore." Mikasa silently argued.

"Mikasa. Now's not the time to argue. We agreed on thi—"

"You agreed, not me."

Levi resisted an agitated groan, his tone grew grimmer, sterner. Even if he was soft to Mikasa at times, it didn't mean he wasn't any less strict with her when needed. "Mika—"

But before he could finish his sentence, Mikasa immediately pulled him aside before shushing him. The sound of footsteps were approaching towards their direction. Both Mikasa and Levi readied themselves, gripping tightly onto their knives. However, a familiar voice echoed the alleyway that caused them to loosen up their grip, but tense their shoulders.

"It's just me yer' little shits."

Taking a peek, they saw Kenny. Kenny Ackerman.

"I got bored and handled yer' business. I would say I pity that old guy but he abused his wife, to the extent his daughter called out to us! Hah! That's a first in a long time." Kenny cackled.

Levi narrowed his eyes, Mikasa slowly approached him after Levi. All three had their masks on, and were prepared to flee should anyone catch them in the shadows. "What are you doing here?" Levi scowled. Kenny scoffed, "Not even a hello to yer' dear beloved Uncle? I'm offended. I thought I taught y'all manners."

Levi rolled his eyes. Mikasa simply looked away. "And my dear beloved niece can't look me in the eye. Ah, no matter. I don't have much time. I gotta' return to my business soon. I have a new job for you. Actually, a solo mission. For…" He lifted his index finger lazily, before pointing right at Mikasa. "For yer'. My favourite niece."

Mikasa tensed, Levi growled lowly. Kenny smirked, and continued before they could oppose, "It's on the surface." What? Both their eyes widened, but their Uncle didn't give them to express their shock at his sudden contradiction. "And, congratulations, for the first time in decades or centuries, my dear niece, your mission involves the royal family!"

Both of them widened their eyes, and Levi was the first to speak, "I'm not allowing it."

"Did you forget who I am, Levi?" Kenny said threateningly, Levi clenched his fist. He didn't wish to start a fight with him, he knew better, he knew the consequences of losing to him. Kenny proceeded to approach Mikasa, towering over her. She bit her lip, in agitation and fright.

"You told us Ackermans don't accept requests regarding the royal family. And you instructed me specifically not to do any solo missions." Mikasa retorted softly, suppressing her fear.

I did say that. But it's time for a change. Something yer' rascals won't understand." Kenny then removed and threw some documents towards them as he began to summarize the context of the situation. "Your identity will be Mikasa Azu. You're from Oriental royalty. Seduce the prince or somethin', because this particular important customer wants information regarding—"

"Seduce?!" Levi interrupted, and just from his tone, it was clear the male was livid and disgusted at such an outrageous idea. "You—"

Before Levi could continue, Kenny took out a knife and was quick to place its tip against Levi's neck, applying a little pressure on it as a threat. "Yer' know better than to shout, didn't I teach yer' that? Ackermans despise unwanted attention." Kenny scoffed, even with his mask on, Levi could feel an eerie smile spreading on his lips. After a tensed moment, Kenny retracted the knife and began to speak, "I'm feeling generous today even after yer' little temper tantrum. If Mikasa permits, yer' can accompany her. There's a reason why I don't want yer' to follow but… oh well. Whatever happens up there, it's y'all fault." Kenny commented, but Levi and Mikasa knew this wasn't an act of generosity, but more of the fact he didn't want Mikasa to suddenly go mad in the middle of town, up on the surface where security was much, much higher.

"This special mission has no room for mistakes. If one of yer' messes up…well…" He proceeded to take out a knife, a different knife. The knife he used to kill their victim. It was stained with fresh, crimson blood.

He waved it in front of Mikasa's face. Mikasa flinched, but nothing more happened. "Seems like yer' getting better at controlling yer' bloodlust. A taunt like this after ya first outbreak made yer' go mad after your first outbreak. Pft. Teenagers and puberty." He joked, ignoring the uncomfortable atmosphere he was practically building up. "Then again, yer' still go cuckoo mad on your lil' shitty bad days when yer' kill." He teased harshly, Mikasa bit back a scowl. "But don't give me that look my beloved niece."

"All the information in those documents. I have other shit to deal with now." With that, Kenny turned and began to walk off. Although, he halted mid-way, turning towards them one last time. "Y'all both better scurry off now." The masked male then disappeared in the shadows.

Mikasa and Levi turned to each other, but before they could open their mouth and say anything else, they heard more footsteps coming, loud voices talking over one another about some racket going on. Ackermans never liked unnecessary attention, because any attention they received was for the worst, so both of the remaining Ackermans quickly fled.

As the Ackerman siblings hid in the shadows while they fled, at the corner of Mikasa's eye, she saw a group of people crowding over something. She then spotted a corpse laying outside the weaponry shop. She then noticed the people grieving, for the weaponry shop owner seemed like a jolly fella who didn't deserve an early demise. But then, she saw a little girl with her mother, crying—not out of despair, but rather out of joy, as if they were free.

Freedom was something Mikasa couldn't even dream of.

"Don't look." Levi chided quietly, "That isn't our mess that we had forgotten to clean."

Mikasa nodded, facing back front as they continued to sprint to their hideout. Deep down, the raven-haired female knew that the mess Kenny purposely left wasn't because he suddenly desired the spotlight, but to serve as a reminder to both of them. A reminder of their inescapable fate and bloody path they were forced to walk and the consequence that he would inflict on them should they fail.
