And a story of an ambitious individual in pursuit of vengeance.

Always make sure your kills are clean, Killu

Killua clutched onto the dagger in his right hand as he eyed his target across the street. He had been hiding behind the limelight for about 10 minutes, waiting for his target to return back to his luxury car. His target, Dorris Gonzales or whatever, had just exited from a house party for whatever business he was in. Not like Killua cared who his target was and how his life was like. He was going to die soon anyway. As soon as his target was about a few feet away from his car, Killua made his move. As soundless as a feather, Killua basically teleported to the white Mercedes. Dorris Gonzales did not notice a thing as he walked to the driver seat and open the car knob. Killua however, was faster. Killua swooped down on the tree branch above the car, tied a white cloth over the target's mouth just in case he had the ability to scream in less than a second, and then stabbed his target through the chest. Killua skewered right into the target's vital organ, and in no time, the target fell, lifeless on Killua's arms. Even if Dorris Gonzales had not been gagged, he didn't have a second to spare to scream out for help. Killua skillfully pulled out the dagger from the target's chest, and immediately cleaned the blood with a disposable towel.

The next step Killua must do was to dispose of the body. Already mapping out the dump site, Killua hauled the corpse over his shoulders, and disappeared into the shadows once again. Only taking ten more minutes to arrive at a secluded park with only one water fountain, Killua gently laid the body down on the ground next to a big oak tree. Taking a quick picture of his dead target, Killua then proceeded to bury Dorris Gonzales with fallen leaves. Taking a look at his awful handiwork for the last time, Killua retreated from the scene. It was time to get his payment.

…..

"Ah Killu, welcome home! Your client left wonderful feedback from your work today! In fact, the number of your request box is overflowing! I knew you would be the most requested worker in our family!" Kikyo Zoldyck gushed as her 20 year old son tossed his jacket to the side. Canary, the family's butler, quickly retrieved the jacket, and bowed down as Killua pushed past upstairs in a rush. Hurt by her son's cold response, Kikyo screeched, "Killu, listen to what your mother is telling you!" When she saw that Killua had no intention of listening, she huffed and snarled, "If that thing comes out of Alluka's body again, we will dispose of her immediately." That definitely worked on the silver haired Zoldyck. Killua stopped his tracks and glared down at his mother. In a flash, he leaped down from the top of the stairs and landed right in front of the cherry-lipped mistress.

With his icy cold eyes, Killua glared and quietly murmured, "She has a name. Nanika is part of Alluka, whether you like it or not." Instead of listening to her son's correction, the lady assassin gasped in delight at how menacing her son was acting. Killua roughly pushed past his mother and decided to change his destination. He passed by the family dining hall, which his youngest sibling Kalluto was at.

Kalluto looked up as his older brother passed by and quietly whispered, "Good work, big brother." Killua only acknowledged the kimono-wearing Zoldyck a nod, before he exited downstairs to their basement floor. Their downstairs to the basement was like a dungeon—dark, hollow, and stony. After a long flight of stairs, Killua finally reached the base floor, and the stairs led him to a long, narrow hallway. At the edges of the hallways were the butlers, maids, and cooks rooms. Each room was about 150 square feet holding one single bed, single wooden desk, and private bathroom. The hallway was long, and on this floor had two giant rectangular sections each serving to be all the non Zoldyck members, with the exception of the giant square room connecting the rectangular sections. After passing by rectangular section A, Killua came face to face with a giant double doors adorned in pink ribbons. Killua knocked on the door three times.

"Come in," a high-pitched voice called. Killua allowed himself in, mentally slapping himself for forgetting that Alluka was a teenager now. It wasn't like he was expecting her to swing open the door and jump in his arms like she did years ago.

"Hey," Killua said in a soft voice, comfortably sitting on Alluka's giant king sized bed. Her room was now filled with posters and make up desks instead of all the toys and dolls she collected when she was young.

Alluka, who was on her stomach reading a magazine, looked up and smiled at her favorite sibling. "Hi. How was work today?"

"Terrible as always," Killua muttered, his heading leaning back as he recalled how he could feel Dorris Gonazale's life fading away in his hands.

"I figured," Alluka quietly said, tracing her finger on her magazine. Killua glanced at what Alluka was staring, and a lump caught on his throat at what he saw. She was wistfully rubbing an image of a high school, with laughing kids around her age.

"Do you wish to go to high school?" Killua asked, patting his sister in the head.

"Nanika does."

Killua swallowed, and the petty insults from his mother from earlier ran through his mind. He then said to the raven-haired girl, "Mom said she would get rid of Nanika if she comes out again."

Alluka angrily shoves the magazine away from her and huffs, "Why can't they get that I have another person in me! Mom and Illumi has some problems in their heads, and so do I!"

Killua shook his head in disagreement, "That's not true Alluka, there is nothing wrong with you."

Angry tears spilled from her eyes, and Killua quickly wiped them off from her. She sniffled, "Nanika helped me go through so much. Because I couldn't handle t-their… their training, Nanika came out to deal them for me. And all the punishments we received… I was only alive because of her." Killua pulled her into an embrace and kissed her forehead.

"I know, sis. I know." Killua rubbed her back in comfort, and as he helped her calm down, Killua said in a soft voice. "I know Nanika is so good. You love her, and I love her. But for her safety, tell her not to come out in a while. Our messed up family can't accept that their precious daughter has two people in one body. They can only love one daughter, as stupid as that sounds." Alluka coldly laughed, sending shivers to Killua's spine. One thing he was afraid of besides his father and older brother was a sinister Alluka.

"What a dysfunctional family we have, brother. You've been killing for more than half your life, and now even Kalluto has been getting more popular than ever. How in the world did the government not catch us yet?"

Killua shrugged, "I guess we have to thank piggy. He is basically our garbage man, cleaning up our traces, finding locations of our next hideout, and building a crazy ass defense system that no one can ever step foot 30 mile radius from our household."

Killua smiled when Alluka finally laughed sincerely, "Oh God, Milluki is actually that important?" The two laughed at their common dislike towards their older brother, Milluki Zoldyck. The Zoldyck siblings continued to lie down on Alluka's bed before another call was made to the silver-haired assassin.

"We got an important client wanting you, Killu, "a slithery voice said on the other side of the phone. Both Zoldycks squirmed at the sound of their feared oldest brother, Illumi Zoldyck.

"Okay, I will be going there soon. Send me the address and target file," Killua said. He ended the call and turned to his sister. Alluka gave him a sad look on her face, knowing fully well how her brother despised assassinating. Returning the sad smile, Killua gave her sister a pat on the shoulder and said, "Well, I guess I'll see you later."

"See you later," Alluka called as she watched her older brother leaving the room. Once Killua exited out of his sister's room, Killua's smile instantly turned into a frown. There was no way Killua wanted to return to this awful place. All this place, his family, and everything here reminds him of his despicable occupation and unwanted memories. Memories of all the torture he endured and insane training he had to face. He knew that this was the last straw, after taking in about 10 assassination requests from 20 hours ago. It hasn't been a day, and he had already passed the average assassinations his whole family takes on a daily basis. He was going to do it. Killua has officially decided that he is going to escape from this life. Tonight.

…..

Kicking down the old, wooden door, Gon rushed inside and held out his gun with both of his hands. He swiftly turned right, then left, and looked straight ahead to the dark, messy hallway.

"Clear!" he yelled, motioning his team to rush inside. Kurapika, Palm, Leorio, Melody, Knuckle, Shoot, and a couple of the FBI swat team all swarmed in. Giving each other knowing glances, Gon and his team all dispersed from the entryway. Half of the team immediately ran upstairs, while Gon and the other half stayed on ground level. Gon and Knuckle, side to side, walked towards the room next to the empty kitchen.

Earning a quick nod from Knuckle, Gon slammed open the door while Knuckle quickly jumped inside the room and yelled, "FBI!" Gon soon followed in after Knuckle and raised his own gun in the opposite direction of Knuckle. Both agents lowered their guns when they discovered that the office was vacant.

"It's clear in his office!" Gon yelled out, scavenging around files on the messy office table.

"Clear in the downstairs bathroom!" another voice responded. Knuckle grunted in frustration, violently swiping the papers on their suspect's bookshelf. Gon continued worked on the suspect's table, until he noticed something odd. Out of the abundant pile of manila folders. tax documents, and maps, Gon found a picture frame. One quick look at the picture frame instantly added fuel to Gon's motivations.

"Guys! I found Laura Crone's stolen picture frame! This guy was definitely here in the last three days!" Gon called out. He repeated the message through his mic in his ear, informing everyone upstairs.

"Copy," Kurapika said through his earphones. Kurapika sighed, observing the serial killer's room. Nick Cue was his name, and Kurapika and his team must find him fast to save Laura Crone. He and his team deduced that Nick Cue was a sadistic serial killer kidnapping women between the ages of 20-40 and torturing them for his own pleasure. Because this man had the guts to kidnap a senator's daughter, his team was assigned to capture him without question. Reflecting back on this mission and what kind of guy they were dealing with, Kurapika ordered through the mic, "Freecss, I want you take someone with you and search outside. He may have a shed somewhere or something that he escaped to. Go quickly."

"Got it," Gon responded. Gon didn't even need to look at Knuckle for his signal. Knuckle was already on the run, forcefully opening the office window and jumping out on the grass. Gon followed behind the eager agent, and then turning on his flashlight for extra light source. Although the moon was out tonight, Gon and Knuckle had to use their flashlights to detect any sign of sheds, barns, or even an outhouse. Through the grassy field that was well above their knees. The two men continued searching until Gon's flashlight illuminated a tiny shed southwest.

"There!" Gon shouted, before breaking into a sprint. Gon could hear Knuckle's heavy footsteps behind him. It only took them ten seconds for the two agents to arrive at the door of the wooden shed. The two immediately noticed that there was a lock on the shed, and now that they are in front of the shed, they could hear faint weeping inside. Quickly making a decision, Gon fired the lock, and without wasting a second, Knuckle slammed the door open. Gon rushed inside and pointed his gun in front of him while yelling, "FBI! Don't move, Nick Cue!"

In front of Gon and Knuckle were Laura Crone bounded by chains and the frozen Nick Cue, who had a torture instrument on his hand.

Knuckle demanded, "Drop your weapon and put both of your hands up where I can see them!" Nick Cue stood still, and the senator's daughter continued to whimper in fear. Impatient, Knuckle shouted, "Drop them right now!" Nick Cue still did not that Nick Cue had not turned his back around, Gon took the chance to sneak around the tables to avoid Nick Cue's range of vision. Knuckle quickly took notice of this, and distracted the serial killer, "I don't have to shoot, and you don't have to harm any more women. All you have to do to walk out of here unharmed is for you to drop your weapon. Right now."

"You don't understand, "Nick Cue whispered. Gon was only a few feet away from Nick Cue and Laura. He concealed himself between the two tables that had all kinds of torture weapons on top, and he had a clear sight of Nick Cue's shaking hands. Gon then took aim, while Nick Cue cried, "She is evil! They all are! I saw her! I saw her infidelity!" The sound of a loud gunshot echoed through the night. Knuckle quickly tackled the wailing serial killer while Gon jumped out from his crouching position and ran to the sobbing woman.

"Shh, it's alright now. You're safe. He won't hurt you anymore." Gon soothed the woman while unchaining her. Now free from her bounds, the woman sobbed into Gon's chest. Gon smiled and patted her head while Knuckle handcuffed their wanted man. By this time, Kurapika and the others rushed inside the shed. Kurapika sighed in relief while Leorio loudly cheered at their victory. Mission accomplished.

…

"Another sweep for our one and only Agent Freecss!" Leorio whooped, slapping the back of Gon's back.

"Sooner or later, you're going to wipe the floors on your father, kid!" Knuckle added, slapping Gon on the back on the other side. Gon chuckled, rubbing his aching back.

"How's this my victory? We all saved Laura together!" Gon pointed out.

"Tsk tsk," Knuckle clicked his tongue as he wiggled his pointer finger. "Who was the one that disarmed insane our serial killer?"

"I did, but—"

"And who is the one that got the girl's phone number!" Leorio interrupted, glaring enviously at the spiky haired agent.

Palm, who was too busy admiring the younger man suddenly flashed her eyes angrily. "That blondie asked for Gon's number?!"

Gon laughed, "I mean, I offered her our team phone number, but she suddenly wanted to get mine for extra protection—"

"You have a lot to learn, miracle boy," Knuckle said while shaking his head. The two loud men continued to tease the young agent, while the mature agents rested back to their chairs in their office room. Their mission was truly a success. Kurapika especially was pleased with the results. Their deduction and the rescue mission itself took less than a day, which only benefits their entire team, the Hunter team. The Hunter team of the FBI may not be a well-known section of the FBI, but they are usually assigned to take care of national crisis that had one of the greatest stakes. He and his team members were specifically chosen as a group to handle the worst of the worst of the worst cases, and they were expected to carry out their mission with at least a 90% success rate. So far, their team was doing splendid.

He was especially proud of their youngest member, Gon Freecss. Gon was certainly the greatest addition to the team when he joined 2 years ago. Despite his young age, the FBI chief accepted him in the team because of his relation with one of the greatest agents of all time, Agent Ging Freecss. As expected, Gon passed the physical test with flying colors and studied well in criminology.

His team members definitely recognized the young agent's incredible talent. Melody softly giggled and interrupted the rambunctious agents' teasings to the younger agent, "Well Freecss, I have to agree with them in this one. You once again disarmed Nick Cue without injuring him. Your aim is deadly."

"Yeah! What she said!" Knuckle yelled.

This time, the quiet one of the team interlude, "It's inspiring to see a young agent have empathy to our suspects enough to make sure they come out unharmed."

"That's why Freecss is so much better than you losers!" Palm huffed, crossing her arms.

"Awh come on babe, don't be like that," Knuckle cooed the attractive lady agent.

"Call me babe again, I will cut your tongue out," Palm growled.

"Ouch," Leorio commented with an exaggerated wince.

Kurapika cleared his throat, grabbing the attention of everyone in the room. He said in a clear voice, "Today, we had a successful mission. The government especially trusted us with this mission since this involved with a figurehead's daughter. This abductions were all over the news, but we have managed to avoid the worst, and saved her in the end. We won't be taking any more cases until tomorrow, so have a good night." The agents blinked at their supervisor.

"Uh Kurt, I hope you know that it's 2 am right now. Even if we had a case, would we really take that at this time?" Leorio nervously asked. Kurapika gave the taller man a blank stare. The staredown between the blonde supervisor and the tall agent lasted a full minute, increasing the tension in the room. For each second passing by, Leorio could feel cold sweat dripping down his neck. "You gotta be shitting me—"

"Of course I was kidding. What, you really think we would take a case this late without proper sleep?" Kurapika responded, still holding the blank stare. Gon and Knuckle bursted out in laughter, while the rest of the time snickered at the stunned agent.

"W-what the hell? You can't just joke like that!" Leorio hollered.

"I can. Now, go back to your homes and get a good rest. We will have a busy day tomorrow," Kurapika ordered.

"Yes sir!" the agents replied.

…..

During this time…

Killua never looked back. Once he slipped past all the butlers and security system from his mansion, he was running like a mad man. He ran on feet, scurrying past tree by tree, hopping over logs, bushes, small critters, and whatever that was in his path. Tonight was the night he decided to finally escape from that household. There was no turning back. Killua grunted when his left thigh caught onto a jagged branch. Ignoring the stinging pain in his thigh, Killua continued to whizz down the slope of the hill. He is not stopping. Stopping means an increase in risk of getting caught by his family members or butlers. Panting heavily from the constant running, Killua estimated that it would take him another ten minutes to reach the bottom of the mountain. He was trained for this. His family force him into arduous training that allowed him to be able to run 30 minutes straight at top speed. Flashbacks of his so called "training" ran through his mind. These flashbacks gave Killua more motivation, prompting him to pump his arms faster, his heart beating faster and faster from adrenaline and excitement. He was this close of being free. Being free from being told what to do, from his stupid job, and seeing his insane family members. Underneath his feet, Killua could feel the steep downwards slope slowly becoming on level to the ground. A few more minutes later, instead feeling the soft dirt, Killua's feet felt the hard, paved road. Killua finally slowed down his pace, and stopped his tracks. He took a moment to catch his breath, leaning over with his hands on his knees. Wiping the sweat from his forehead, Killua looked back behind. Still breathing heavily, Killua stared at the tall mountain he and his family had been hiding in the last year. And now, he was finally seeing his former house at a far distance. He is has officially quitted his job as an assassin.

Killua let a smile form on his lips. He did it. He managed to run from home and his family. Taking a last look up at the foggy mountain, Killua turned back around and ran alongside the road. Eventually, an orange truck ran across the running man. Wearing a navy blue hoodie to conceal his hair and face, Killua didn't flinch when the orange truck in front of the fleeing man. The driver rolled down his window, revealing a somewhat big man with black bushy eyebrows.

A bit confused and scared, the driver asked, "What are you doing, man?"

Killua shrugged and answered, "Jogging on the road, you?"

Relaxed by Killua's casual response, the driver chuckled, "At this time? You should watch out, there has been occasional murders here in this area."

"Then what you doing here, driving around at this dangerous time?"

The driver shrugged too, "A mountain marathon is going to be held soon, and my business be a part of it. I needed to find a good spot."

Killua snorted, "Aren't you earnest." The driver noticed how the stranger in front constantly look behind him as if he was expecting someone to sneak up behind him. And in truth, it seemed like this wanderer is lost and in need of a vehicle.

Hoping he wouldn't regret this, the driver told the stranger, "Well uh, do you need a lift? I won't ask why you're really running in the middle of the road." Killua hesitated at first, but decided that it was the best option he had. If his family figured out that he had ran away about now, it wouldn't take them long before they send a search party. In response to the driver's offer, Killua let himself in the passenger seat and closed the door. The driver nodded and then started to drive off the road.

As Killua watched through the window the sides of the mountains, Ikalgo peeked at the side mirrors. He noted how the stranger he invited to the car had piercing blue eyes and shiny, light hair. The driver swallowed, realizing that he had never seen this kind of person before. He had seen many kinds of people from different races, but who is this man exactly? Who in this country has the kind of eyes, pale skin, and shimmering hair?

The stranger interrupted the awkward silence, "Hey, can you drop me off a motel along the way? You can drop me off in any motel that is in the way to your destination."

"Sure thing, By the way, I never learned your name." Killua hesitated, contemplating whether to give him his real name.

"I'm Lukia. Yours?"

"Name's Ikalgo."
