Standard disclaimer: I don't own shit so don't sue me. Well here is the second chapter. To be honest I'm not really happy with the pacing of this chapter and the first. It's too slow for me but at the same time I want to write in a detailed fashion… lemme know what you guys think by dropping a review: fast pacing or slow pacing?

I was really happy with the reaction to my first chapter; it got a lot of favourites, followers and reviews. Well to me it was a lot at least anyways.

So yeahhhhhh. Have fun y'all:

After Naruto had activated his ability he felt a wave of exhaustion hit him. That was probably the most tiring thing he had ever done in his short life. His eyes drooped for a second but his head snapped up when he remembered that there were a few things he had to take with him before he left. He then dragged his drained and tired form towards the other end of the room to get them.

At the same time Zeno was checking his surroundings using En. From what Naruto had told him it suggested that at least two people were aware of Nen in the household, perhaps more. If that was the case then there was no way they wouldn't have felt that big release of aura. At the moment Zeno's En covered the entirety of the house with ease. Although it was a relatively rich household, with long hallways and large main quarters it was still easy to monitor with his En because of is range.

Zeno could see that there were one or two guards walking back and forth near the front entrance, the main quarters and out in the garden. None of those people had a significant amount of Nen in their bodies however there was one with a moderate amount of Nen.

And he was heading right towards Naruto's room.

He turned back to the blonde boy and saw that he had gathered a couple of things in a little rucksack that he had pulled out from underneath his bed. Among the items he had grabbed Zeno could see that there were at least a dozen chocolate milk cartons, which made him sigh in exasperation, and a necklace that had been stashed in his sock drawers. Zeno gave it a once over and was surprised at the quality of the stone that hung from its end. The boy could probably get quite a bit from that if he sold it.

Well it wasn't any of his business.

He walked towards the window and began, "We're leaving. There's someone coming, no doubt due to your little light show, and I make it a habit to never kill anyone but my targets." Zeno popped it open and turned around to see Naruto give him a puzzled look,

"Wait so I really was your target? Huh… this must be one hell of a job then!" He finished with a wry grin and came to stand next to his had-been assassin. Zeno only sighed at the cheek on this kid. Somehow he had known that the old assassin did not mean any harm to him from the moment he had seen him. The Zoldyck patriarch grabbed the kid from the scruff of his shirt before he commented,

"Still wearing your pyjamas; you don't want to change?" The old assassin questioned as he observed the kid's pyjamas. It was comprised of a blue long sleeved shirt with clouds floating along lazily and matching trousers. Naruto had also put a sleeping cap on top of his head that looked like the jaws of some Magical Beast were closing around his noggin.

Hey he liked to sleep comfortably alright.

The blonde let out a yawn before replying, "Nah you can give me some clothes when we get to where we're going," At this point Naruto's sleepy eyes gained a sharp glint, "after all neglect can be pretty harmful ya know…?" and he gave the deadpanning assassin a cheeky grin coupled with a victory sign.

He truly was a cheeky kid. And his ability could even be more annoying than Zeno had predicted. If Naruto's statement was true it meant that 'harm' could mean anything that was harmful not only to his body but his mind too. He pretty much was nigh invincible.

Or so he thought. Unbeknownst to him even if Zeno did suffer the exact amount of harm Naruto did he could more than likely take it. The old assassin made a note to keep that to himself so he wouldn't give Milluki any ideas. That boy was growing a cruel streak that could be seen from a mile away.

He then jumped out of the window just as the door was opened by the hunter under the family boss's command. The hunter meant to give chase but Zeno only glanced back and any thoughts of fighting the old man that was kidnapping his charge fled his mind in a hurry. He was not being paid nearly enough to go against someone of the perpetrator's level. The hunter did not even know that said perpetrator was the second oldest member of the Zoldyck family alive and even though he was old he was still one of the most dangerous men on the planet.

That decision to avoid a confrontation saved the hunter's life.

Instead the man made his way towards the boss's room, thinking of a way to break the news. He then started making plans for the future in case he got fired. Well on second thought he was still pretty valuable to the family. If he played his cards right he could pretty much coast along on his laurels for the time. This thought was justified by the fact that he was being paid quite a bit for jobs that weren't all that difficult.

He arrived at the boss's room and glanced at the two people who were on guard duty. They were two youngsters who had been climbing through the rank of the family ever since they joined. In fact the hunter was not surprised if he was given a mission to instruct them on Nen any time soon which gave him an idea. Smirking at his quick thinking he knocked once before a voice called out to let him in.

Going inside he looked at the man on the other side of a mahogany desk. Sitting on the plush chair was his current employer, the family leader who was currently in his thirties. The man lit a cigar and leaned back on his chair, crossing his legs. He began to say something but the hunter beat him to the punch, "The kid's missing. I just checked his room and he ain't there. The window was open." The lazy hunter had decided that the boss man did not need the whole story. Had he told him that he had seen someone kidnap the kid and hadn't given chase he would've undoubtedly been fired.

So there was no need to tell him that little detail. The hunter did not know that had he been fired this night, or perhaps even later due to the events that had occurred, it would've saved his life later on. Instead the desire to mooch off the mafia family's money in order to have a relatively comfortable life made him keep his mouth shut.

The mafia leader choked on the smoke and began shouting at him, "W-What did you say!? He was your responsibility! Alert everyone and begin searching immediately!" The boy was an important factor in many of his plans later on down the road and his power would be crucial towards fulfilling his goals.

The hunter only nodded and made to leave before he added in another comment, "Well I'm sure he couldn't have gone far. We'll find him soon enough," and now to get in the boss's good graces and increase his reward, "Afterwards I'll start teaching those two kids Nen. They should come in handy down the road right? Of course that's gonna be extra but I'm sure we can figure something out…" The hunter trailed off. Whilst the family leader was pleased with his employees' sense of initiative and the idea of having other underlings who could use Nen, he had no doubts that the man was simply finding ways of increasing his own pay check. It would prove to be a worthwhile investment in the long term so he wasn't too worried though.

"You better find him…" He trailed off and his greedy underling replied as he headed out.

"You got it Mr. Nostrade."

Zeno had travelled through the night and had made good headway; Naruto had not been staying very far away from his home after all. Of course when Zeno thought that it wasn't very far away that was only because he could cover the distance in over ten hours. That distance was from a city on the north of the Republic of Padokea to his home at Kukuroo Mountain and was approximately over 500 miles. To anyone else that would've been impossible to cover in ten hours but he wasn't a Nen trained elite assassin for nothing.

When Naruto had woken up they were standing in front of the famous Testing Gates of the Zoldyck family. Noticing that Naruto was now awake he put him down from his back. Half an hour into the journey the kid had fallen asleep and Zeno had propped him on his back. It wasn't very comfortable, or safe, to hold him by the nape of his shirt and run at high speeds after all.

"Ah master Zeno you are back." The gatekeeper Zebro greeted his employer but made no attempt to question who the kid that he had brought along was. It wasn't any of his business and there was sure to be a good reason behind it.

Naruto yawned and stretched and then spoke to the gatekeeper, "Morning chief, how's it going?" Zebro glanced at his employer and was promptly ignored. Instead the old assassin walked towards the massive gates and with a simple push he opened all seven of the right panels as if it was nothing. Zebro had seen this many times but it still made him shake his head in astonishment. Zeno, and most Zoldyck family members, really were on another whole level. The noise of the massive gates opening had captured Naruto's attention and he turned around to look at them. His jaw dropped at the massive gates that were being opened with relative ease by his current employer.

Seeing the kid's astonishment Zebro decided to explain, "Those are the Testing Gates. The first two panels weigh 2 tons each. The following panels weigh double of the previous and so on and there are 7 in total. Meaning that master Zeno just pushed open 128 tons with one hand… I'm always impressed even though I've been the gatekeeper for two years now." At the end of Zebro's explanation Naruto only stared at the old man's back with a massive sweat drop. The geezer was an even bigger monster than he had imagined. No wonder he hadn't been worried about being found out whilst in the house. For the first time Naruto kinda felt out of his league and wondered what exactly he had gotten himself into. Well he had no choice now cause there was no backing out of a contract.

Actually that made a question come to mind. What would happen to Naruto if he broke a contract? He had always followed the rules of his contracts and every time one had been broken it was due to the other parties' actions. It was something to keep in mind for later Naruto figured as Zeno turned around and told him to hurry up.

The old man thought that the sooner he could set things into motion the better.

After a lengthy stroll in the woods, in which Zeno had explained that the entirety of Kukuroo Mountain belonged to his family, which had consequently made Naruto's head swim at the thought of what their coffers must look like, Naruto had met the family pet.

Mike was terrifying.

Naruto had been listening to the old man's explanations and hadn't noticed the giant dog until he bumped into him. It had taken all of his self-control to not scream in terror. Zeno had quietened him down by stating that Mike would not attack him unless Zeno told him to and he didn't plan on doing that so Naruto was safe.

He was still shaken but at least he wasn't going to become dog chow anytime soon.

Afterwards they passed through the gatekeeper's quarters as he had been informed by the butlers stationed there. At first they weren't sure if they should answer the blonde's questions but after a relenting look from Zeno they had informed him some more about the estate. Kukuroo Mountain was 3722 meters above sea level and had belonged to the Zoldyck family for generations now. All of the butlers that were hired were handpicked and trained from a young age in order to better protect the family members. After seeing what the old man was capable of the blonde wasn't sure if they needed protecting at all but kept that to himself. Naruto also wasn't quite sure what sea level was exactly but he just figured that it meant the mountain was pretty damn high.

They passed over the butler's quarters too where a young man with glasses with pointed frames and an impeccable black suit had greeted Zeno. The old man ordered the young butler, whose name was revealed to be Gotoh, to tell the family members that were in at the time that he was calling a family meeting and thus to go to the meeting room. Gotoh nodded and then called, "Canary, come here."

From seemingly nowhere a dark skinned girl, who seemed to only be a year younger than Naruto, appeared next to Gotoh. She wore a black pantsuit and had her hair done up in a weird fashion that reminded Naruto of a jester hat with multiple points. Naruto had thought about pointing that out to have a laugh but after seeing the short staff that she had in hand, which was rounded at one end and pointed out at the other, which looked incredibly sharp, he swallowed the comment he had on the tip of his tongue.

"Take Zeno-sama's guests' things and put them in one of the guest rooms." Gotoh ordered the newly hired butler's apprentice. She nodded and went to do as she was told but Naruto put his rucksack on the ground and fished out a milk carton. He then handed the rucksack over to the girl with a grin. Before she left Zeno added in that she should try and find a room as close to either Killua's room or his own.

"Yes sir." Canary replied and rushed off. Naruto was shocked at her speed. He doubted he could match that even if he tried his hardest. 'I wonder what kind of training she's gone through…'

Gotoh then bowed and rushed off to complete his own task. If Naruto had been surprised by Canary's speed he was blown away by Gotoh's. The man had literally blurred out of sight. Still reeling from his shock he was forced to jog in order to catch up to the old assassin. With that giant beast of a dog Mike lurking around he did not want to get separated from Zeno.

A couple of minutes later Naruto felt something trigger his self-dubbed sixth sense off. He squinted his eyes and peered through a cluttering of trees to his right. Zeno then spoke, "What is it Milluki?" and from the direction Naruto had been looking at a chubby kid who seemed to be ten walked out from behind a tree. He was wearing a grey hoodie with an image of some kind of anime character and was holding onto the hands of a two year old. The toddler was wearing a grey sweater and blue pants and had his hand in his mouth. In all honesty the little kid was quite cute but there was something that creeped Naruto out about him. It wasn't even his sixth sense, just something felt weird. Deciding to ignore the feeling he tuned in to the conversation in front of him.

"Grandpa I heard you were back. Who is this?" The chubby kid greeted and questioned his grandfather in the same breath. Naruto stored the info that he was Zeno's grandchild for later and assumed that the toddler with him was another grandchild.

"Well it's good I've already found you. I'm calling a family meeting and I'll explain everything there so come along." The so called Milluki nodded and matched their pace towards the mansion. Normally Naruto would've said something but his sixth sense hadn't stopped. It had only gotten worse which meant that it was indeed coming from the chubby kid next to him. This disturbed Naruto which is why he didn't strike up a conversation, instead he just decided to ignore him although he did smile at the toddler. Even though he had been kind of creeped out at first the little one was cute so he put his previous thoughts behind him. In return the young child had only looked up at him with a blank face and a spark of curiosity in his eyes.

Deciding to at least say something Naruto questioned Zeno, "What's the chibi's name?" The old assassin glanced at the boy from the corner of his eye and replied that he was called Kalluto and was Zeno's youngest grandchild.

About twenty minutes later they finally reached the mansion. Naruto whistled as he looked up at the giant house in front of him. It put the Nostrade families' to shame. The house was absolutely massive and was made up of an architecture that hinted at both good taste and a like for the traditional look. Not that Naruto could tell because at this point in time he wasn't very cultured at all.

They walked through the halls and Naruto noticed that there were various paintings, some probably of family members; in fact he saw Zeno's and one of Milluki along with others. There was one of a muscled and stern faced man with long flowing silver hair and slitted blue eyes. Next to his there was one of a woman in a black kimono with her hair pulled up into a big bun. The strangest thing was that she had an electronic visor that covered her eyes.

Naruto was beginning to think that everyone in this family were weirdos.

He'd look back and see that he had no idea how right he was at the time.

The next one was of a teenager with jet black hair that reached his shoulders wearing long sleeves and a shirt underneath and grey pants. The guy kind of looked normal, except for his seemingly empty large black eyes.

They finally arrived at a large room which was mostly taken up by a long table. Naruto assumed that this was due to the fact that the family itself was large. Standing at the space available past the table were all of the people Naruto had seen in the paintings along with another boy. He seemed, like that Canary girl, to be a year younger than Naruto. The boy had spiky silver hair, very light skin and blue eyes. He wore a blueish green jacket and a blue turtleneck sweater underneath with blue shorts.

"Everyone's here, good. This young'un here is someone I met in my last mission. His name is Naruto Uzumaki and he was my target but I decided to bring him along instead of killing him." Zeno gestured towards Naruto and he waved at them. Killua smiled at the kid's nonchalance at the fact that his grandfather had announced that he had been supposed to kill him and waved back to him.

'Well at least he seems to be normal.' Naruto noted with happiness.

"I see…" Silva trailed off as he waited for his father to continue on. There had to be a pretty good reason for Zeno to bring back his mission target instead of killing him. Naruto interrupted then by pointing out something that Zeno had confirmed,

"Ah so you really were hired to kill me. I half thought you'd only said that to get a rise out of me old dude." The blonde said in between sips of his chocolate milk. Killua only blinked in puzzlement; didn't he find this situation weird? Killua then concluded that the chocolate-sipping strange blond must be special if his grandfather spared him.

"Hmph, I did say that before didn't I kid?" Zeno replied as he glanced at the short blonde out of the corner of his eye and he hummed in confirmation.

"So what's my job exactly old dude? You haven't really told me anything about it." That fact was actually kind of bothering Naruto. The reason why was because in hindsight he realized that he might've screwed up when he worded the contract. In the contract Naruto hadn't specified what the job or request was. How did then the contract know if Naruto had fulfilled it or not when he completed the task? It was a thought that he had been pondering upon through their walk up to the mansion and it scared him.

What if the contract could not be fulfilled because Zeno had not told him what the request was even if he completed said request? In Naruto's mind that basically meant that because of the way he worded it he would be bound by it forever. However if he couldn't complete the contract he always had the choice of breaking it. But that again lead to the question:

What would happen to Naruto if he broke one of his own contracts?

Naruto didn't want to find out in all honesty.

"Youngsters these days… I was getting to that kid. I want you to make a contract with one of my grandchildren. I'll tell you the terms so don't worry about that." Zeno picked up from where he left off. To Naruto it didn't seem like that big of a deal but according to the reactions that statement roused it apparently was.

"Honourable grandfather you cannot mean…" Silva's wife, Kikyo Zoldyck spoke up with a hesitant tone. Her husband next to her only frowned and took a closer look at Naruto. He had noticed that the kid a high amount of Nen for his age but he was apparently even more special than he had first seemed. Killua then questioned Zeno,

"What do you mean by a contract?" He gazed curiously at his grandfather. Naruto decided to jump in and explain his talents. It was partly because ever since he had seen just how awesome it was Naruto had taken a particular pride in his ability but it was also so he could hopefully make a good impression on the normal looking silver haired boy. It wouldn't hurt to have a friend whilst being here right?

"Basically I can make contracts with… uhm I think it was called Nen. And whatever terms I write down in the contract have to be followed by me and whoever signs it. If there's a breach in the terms then whoever broke it will be punished accordingly. I'm not entirely sure but I think that the more complicated the terms the greater the punishment although I haven't tested whether that's true yet." Naruto spoke in between sips of his chocolate milk again. Killua hummed in response. His grandfather had explained that later on Killua would develop his own assassination techniques through a special power. He wondered if it was the same thing.

"Another thing that I've noticed is that the contract is binding in a physical sense too." Zeno added in his own two cents. Naruto turned around to look at him with a confused expression,

"Whaddya mean physically binding? Huh?" Zeno sighed and explained that on the way here in order to test what would happen if he tried to harm Naruto under the influence of the contract he had set the blonde down for a second and acted as if he would attack him. Much to his surprise he had felt an actual force restrict his movement and it wasn't until he banished any thoughts of harming the blonde that the force had left him and he was able to pick him up again. Zeno estimated that he could probably have been able to break the force with a combination of pure strength and Nen but he had deduced that if the binding in the contract was this strong it meant that the consequence for breaking it would be worse.

Naruto completely ignored the fact that the old man tried to hit him or worse whilst he was asleep and questioned his logic instead, "But with the way I worded it wouldn't you have just taken as much damage as I did?" he would've continued with the logic but he realised where it lead.

If Zeno was simply tough enough to not care about the damage he took didn't that make the contract a bit pointless? Sure he would take the same damage as Naruto but if he was strong enough to ignore it, in other words if his pain tolerance was high enough, then it didn't matter to him. On the other hand whilst Naruto had been beat in the past and it had built up some pain resistance it probably wasn't on the level of an assassin like Zeno.

The old man pretended not to realise the follow up of Naruto's logic and spoke again, "Perhaps however there's no guarantee that I wouldn't be penalised separately. Once for breaking the term and another time for breaking the contract itself. With what you've told me all the terms that you've made so far were along the lines of 'do this or you'll die'. When a person would break these terms they would be punished for breaking the contract and as a result they would be assaulted with your Nen. However you assumed that they had been penalised for breaking the contract and not for both failing the terms set which thus led to the contract being broken."

Naruto stared at him as his mind tried to comprehend the old man's logic. So he was basically saying that because previously the punishment for breaking a contract with him was death, he couldn't tell if a person got penalised for going against the term set and then penalised for breaking the contract? Because in the case of breaking a contract where the punishment stated for failing the term was death then either way the person would die right?

Naruto continued to ponder this as he looked down at the ground. Silva, Kikyo and Illumi on the other hand immediately understood why this ability was both useful and dangerous. If there was a separate penalisation for failing to follow a term and for breaking the contract this meant that even if you survived the first Nen assault there was still a chance to be done in by the second.

And if what the blonde had said about the more complicated the terms, the more powerful the contract and the more severe the consequences for breaking one was true it meant that if this ability was used properly it could be incredibly powerful.

Illumi was very interested in it.

Naruto, because he was so deep in thought, missed the calculating gaze that Silva's oldest son gave him.

"Hmmm that sounds pretty handy… by the way who did you mean grandpa?" Killua questioned after admitting that it sounded impressive.

"He means Alluka right?" Illumi answered Killua's question with his own. The young assassin then frowned. A contract with Alluka? But from what they had been told breaking one was dangerous so wasn't it dangerous to make one with Alluka in the first place?

"Grandpa… what kind of contract?" Killua stepped forward and Naruto was surprised at the sudden hostility in his tone. He wondered who Alluka was before concluding that young boy must've cared about him or her. Along with the hostility there was also a hint of protectiveness in his voice.

Zeno stared at his grandchild. He had the same thoughts on the way. Zeno would be the last to admit but his decision to bring Naruto along to make a contract with Alluka had not been entirely thought out. Which is why on the way here he had been thinking of a safe contract to make. The old assassin came to the conclusion that completely restricting Alluka's abilities would probably be the best thing to do. That way she would not make any requests and thus it would be safe to let her out of her room. The obvious downside was that they would lose an incredibly powerful tool to the family but considering the fact that they currently were not using her because they were afraid of the repercussions it would be pointless to make a contract that would do less.

"Hmmm… ideally one to seal her abilities. Even if it is temporarily it'd be for the best. Don't you agree Silva?" Zeno replied and looked to his son. Killua thought about what it meant to seal Alluka's ability. This meant that she wouldn't have to be locked in her room anymore right? He could take her outside on his walks and play with her and not have to worry about her making requests anymore.

It almost sounded too good to be true.

Killua adored his little sister; she was one of the things that he loved the most in his short life. It was for this reason that he wanted to spend as much time with her as possible. She was a breath of fresh air from the darkness; from the assassinations that he was sent to do, from the bloodshed and from the immense pressure put onto him from his family. Alluka did not expect anything from Killua except for his unconditional love which Killua was more than happy to give her.

"…You can do that?" The boy murmured in the silence that had taken over the room. Silva along with Kikyo had been thinking whether that was the best solution and thus had not replied to Zeno's question. Naruto blinked and tilted his head,

"Well I can try. Actually I have to try cuz otherwise I might get punished for breaking the contract ya know?" the blonde replied to the child assassin. Killua frowned before biting his lip. Silva looked at his son and then spoke,

"Killua?" the boy in question turned around at his father's voice and the older Zoldyck continued, "What do you think?" Killua blinked in shock. He was actually getting asked his opinion about something like this? His mother turned to her husband and frowned at him. Killua was talented yes but he was too young to be involved in these matters, he didn't even know what Nen was yet!

"Dear, Killua-kun isn't old enough to know what's best." The child frowned in annoyance at his mother's logic but his father then replied,

"That may be the case but Killua is the one who knows Alluka best. I want his opinion on this matter." Silva explained as he crossed his arms. Milluki was the next to protest but a sharp look from his father shut him up. Looks like he was still pissed about Milluki using Alluka's powers to get him a brand new computer. The chubby kid swallowed what he was going to say next and only held onto Kalluto's hands tighter.

Killua looked at his father for a few moments before replying, "I think we should do it. I don't want Alluka to be locked up in that room forever." Silva considered his son's response. It was what he had expected. Killua was very emotionally attached to Alluka and in a way that was a good thing; it meant that Killua would undoubtedly do what was best for his little sister. But the logical part of Silva added in that what may be best for Alluka may not be necessarily best for the family as a whole.

In this case however he agreed with his talented son.

"I concur, this is probably the best solution for Alluka's and the family's sake." Silva nodded his head and Killua smiled at his father. He then turned around to Naruto and in a flash was shaking his shoulders,

"There you have it so you can make that contract thingy now right? Hurry up and do it then!" Naruto was mercilessly shaken around like a ragdoll, his head being whipped back and forth before Zeno put his hand on top of Killua's head to calm him down.

"Killua, he needs to meet Alluka first. And before that he also needs to see clearly so stop shaking him."

"Ah I see then. Sorry about that." Killua told Naruto as he let go of his shoulders. The blond stumbled around a bit with swirls in his eyes but gave him thumbs up anyways. Silva then decided to intervene as well as explain something to his son,

"Killua we won't have him do it immediately." The silver haired child turned around with a disappointed look and questioned,

"Huh why not pops?" Zeno was the one to reply to him however,

"It's because we first need to see what the safest way to use Naruto's power is. You don't want Alluka to get hurt right?" Killua nodded in consent before stepping back.

The blonde in question had finally gotten the swirls out of his eyes and spoke, "Well there ya have it… Killua right?" Naruto said and the child assassin realised that they hadn't been formally introduced yet,

"Yeah, Killua Zoldyck; nice to meet you," Killua then turned around and began to introduce the rest of the family members one by one, "That over there is my dad, Silva, and my mom Kikyo," he motioned to the stern faced man with the slitted pupils who only nodded back to Naruto and the woman with the strange visor who gave a 'too nice' smile at the blonde, "Over there is my big brother Illumi," Next he motioned to the tall young man with the empty black eyes and short haircut who waved and greeted him happily. Naruto could tell that the smile wasn't all that truthful but he didn't care enough to try and figure out why.

Then Killua questioned Naruto, "You met Milluki and Kalluto on your way here right?" the blonde nodded his head and replied,

"Yup, the chibi and the… otaku right?" Said mentioned otaku grew a tick mark at being called out whilst the chibi only tilted her head. Killua laughed at the new kid's description of Milluki and decided that they would get along just fine.

"Well you already know grandpa Zeno so that's everyone in the family. Have you met Canary and Gotoh?" The child assassin asked Naruto and said blonde replied that Gotoh was the tall teen with the framed glasses whilst Canary was the young girl with the peculiar hairstyle. Killua nodded in satisfaction at the fact that he knew.

A growling sound was then heard and Naruto then questioned, "So when's breakfast?" He rubbed the back of his head in embarrassment whilst chuckling.

That was six months ago. Now he was going to make the contract with Alluka. Over the past six months Naruto's ability had been stretched, pulled, squashed, and pretty much tested in every way that the eccentric family could think of. He said eccentric but he really meant crazy. Illumi was a complete creep whilst Milluki was incredibly annoying. Kalluto wasn't too bad and he enjoyed playing with the toddler. Kikyo was not that bad when he got to know her but he was still put on edge when with her.

The ones he liked the most were Zeno, Silva and Killua. Whilst he already liked the old man because he was witty and fun to talk to he had been surprised that Silva was rather easy to talk to as well. Killua had practically dragged Naruto into his father's room when he had learned that Naruto was hesitant in speaking to the man because he thought he was intimidating. His newest friend had simply asked his dad to tell them stories of his adventures and fights and just like that the awkwardness had been broken.

Naruto had been more sucked in than Killua by the tales. The boy figured that it was because Killua had heard stories like these quite a few times and had even had his own adventures on his assassination missions.

In all honesty Naruto had not believed Killua when he had said that he was an assassin but after a short demonstration of what he was capable of he had taken back his words. And he had also been jealous. The boy was actually two years younger than him but he was incomparably stronger. It was the same with Canary too; she was the same age as Killua and was too stronger than Naruto in every way. From pure strength to speed to stamina they had him beat.

Killua had offered to show Naruto some things and the blonde had been excited but their hopes had been brought crashing down when they spoke to Zeno about. The old assassin told them that Naruto could not have any harm done to him otherwise it would break the contract they had signed.

It was then that Killua innocently suggested that in that case why didn't they simply alter the contract?

Both Zeno and Naruto stared at him as if he was from another planet for a couple of seconds. They blinked a couple of times and Naruto admitted that he had never thought if he could do that. Killua encouraged him to try and Zeno agreed that it was a good idea, and that it opened a lot of possibilities.

Naruto had then sat himself down on the floor and thought of how he would go about doing this. He thought for all of two seconds before deciding that he would simply do just as he had done previously; he simply wished for his ability to activate and it did.

"Deal with the Devil: The Contractor, activate!" After those words and a burst of Nen the roll of parchment that Naruto wrote in to make contracts appeared in his hand along with the bottle of ink and the black quill. The parchment was completely blank and Naruto figured that he needed to call up the one that he had made the contract with Zeno on.

Making his intentions known by speaking out loud Naruto continued, "Amend the contract made with Zeno Zoldyck!" After that was said the words began to appear on the parchment and Naruto realised that it was the contract he had drawn up. Then it rolled upwards so there was more space to write on it and the writing that was on it previously became translucent. The words seemingly lost the solidness that they had and Zeno commented that it was perhaps because the contract was being reviewed with the intention to be amended, therefore it signified that Naruto had not made the decision whether he would reaffirm those terms or not.

It was thus that Naruto had written the contract again but this time he had added the exception that should he beforehand have agreed to it harm was allowed to befall him as long as it was in a controlled manner. Satisfied with his work he read it all over again and immediately noticed that there had been another change, one that he had not made.

Whereas before it said that Naruto would fulfil Zeno's request, now it said that Naruto would fulfil Zeno's request which was to make a contract with his granddaughter, Alluka Zoldyck.

The contract had updated it by itself. This told Zeno, Naruto and Killua (after it had been explained to him what else had changed) that his ability was sentient to an extent, or it at the very least was based on what Naruto knew at the time and could be updated as he gained new information.

The fact that Naruto could alter the terms in contracts previously made and that said contracts could change as new information was introduced encouraged Naruto and the Zoldyck family to test his ability even more. They had discovered the following things:

Naruto could not alter a contract more than twice. A third attempt would result in the contract being nulled. He also did not need the other parties' consent to altering the contracts like he did when first making one. His max of five contracts a day could be upped because after he had done some training with both Killua and, later on at his request, with Zeno his physical capabilities and Nen reserves had been improved upon and his current max was ten contracts a day. This also showed that the strength of a contract that Naruto made was directly linked to how strong he was Nen wise.

Zeno had taught him the basic Nen techniques that any Nen user could use. The basic ones were Ten, Zetsu and Ren. The old assassin explained that there was the last one called Hatsu however it was the technique that Naruto was already using in order to make contracts so there was no need to reteach him it.

They had then moved on to other techniques such as Gyo, an advanced application of Ren, by which a Nen-user can concentrate a larger than normal portion of their aura into one specific body part. Gyo increased the strength of that one body part, but it left the rest of the body more vulnerable because less aura would be flowing through it. Zeno told him that Gyo was most often used in the eyes, allowing a Nen-user to see aura and things which would otherwise be hidden.

Naruto asked what he meant by that and Zeno replied by teaching him about In, an advanced form of Zetsu, which is used to almost completely conceal the presence of a Nen-user's aura. In could also be used on a Nen-user's Hatsu ability to make it invisible to other Nen-users.

His current instructor had explained about En, a technique where you combined Ten and Ren. It was used as a scouting technique because you deployed your aura around you, usually in the shape of a sphere, and you could feel the shape and movement of anything in it.

Naruto commented that it probably came in handy for assassinations and Zeno replied that sometimes it did. For example when he was in the mafia family's house he had used En to monitor any incoming threats. However the man explained that the downside to En was that it could be felt by skilled Nen users which meant that using En was like broadcasting that you were scouting for something.

The old assassin and Naruto's Nen instructor for the time being had then taught the blonde about the other basic techniques. They were Shu, which was an advanced application of Ten where a Nen-user would shroud an object with aura in order to fortify it.

Ken: a defensive application of Gyo all over a Nen-user's body. Zeno told him that this was an incredibly important technique which was most commonly used when you were being cautious in a fight and were hanging back and analysing your opponent.

In contrast to that there was the 100% offensive technique Ko where a Nen-user would focus their entire aura into one body part, or a weapon they were using, for maximum damage. Zeno had explained that Ko was a risky technique because it left the rest of your body unprotected and one attack from a Nen-user could be devastating in that condition.

Lastly there had been Ryu, which was the practical real time use of Gyo in a fight. This was when they had begun to spar. Zeno could not be bothered because he was tired of teaching things to the youngster whose thirst for knowledge seemed to be insatiable and thus Illumi had stepped up to the challenge.

Naruto had gotten the crap kicked out of him.

Illumi was an absolute monster. Nothing that Naruto tried worked. He had tried everything from throwing dirt into his eyes to trying to ambush Illumi using Zetsu to simply rushing him at his fastest but he simply was not good enough. Even after the physical conditioning that Naruto had gone through with Killua he was simply not skilled enough. Naruto had gotten frustrated and used Ko in order to try and actually land a meaningful blow on the teenager but he had simply blocked it using Gyo almost effortlessly.

Zeno, who had been watching by the side lines and whom had been joined by Silva and Kikyo after they had felt the flux of aura at the front of the house, commented to them that this was a good idea. It served to keep the blonde humble and to increase his skills so a safer and more powerful contract could be made with Alluka when the time came.

Neither Silva nor Kikyo commented on what exactly was the use of keeping the blonde humble to the family out of respect for the old man but also because they understood to an extent.

They had gotten attached to the odd Nen genius. It was hard not to, the kid had a warm personality and his quirks made him endearing in a way. He did not judge or find their ways weird but instead asked and commented on the things that he found interesting with a simple mindedness that only a child could have.

He had also befriended Killua, which Illumi had been against first because he argued that Killua did not need friends, but Silva had shot that idea down when he stated that Killua had been more focused and determined to succeed ever since the blonde had come to the household. Zeno explained that it was because Killua saw Naruto as a rival as much as a friend; they competed against each other in order to see which one was better and this drove Killua to improve.

Illumi had seen the advantage in this and thus had backed down. It was because of this that he had even volunteered to spar against the blonde so the Nen genius could practise the Nen techniques that Zeno had taught him. He figured that the more he pushed the blonde, the more Naruto would push Killua and thus the stronger Killua would become. Deciding that there was no harm in it he trained with Naruto in gusto in between missions.

Of course if you asked Naruto it was more like torture. The teenager curb stomped Naruto whenever he was home. The blonde would be covered in bruises, cuts and even sometimes burn marks after their training sessions. And when Illumi would leave on a job he would order Gotoh to pick up the slack and drill the blonde into the ground.

Per his master's orders Gotoh would do just that. The young butler commented to Naruto that it would serve to improve the blonde's skills and that Gotoh could practise his own which led to Naruto having to run, duck and dodge for his life as the, in his opinion, sadistic butler fired coins with the power of bullets at him.

Seriously those things could pierce trees, they were insane!

At the same time Killua did not wish to be left out of the fun and had approached his father about Nen. Silva could not argue that Killua was too young to use it if he did not think that Killua was too young to commit cold blooded murder and thus had decided to teach his son a thing or two. The young assassin was taught the basic techniques like Naruto had been taught and had taken to practising with the young blonde as well as Gotoh and, sometimes, Canary.

However it had payed off a lot. Naruto was now, both Nen wise and physically wise, more than twice as strong as he first was when he was working for the mob family.

Also whether the strength of the contracts would increase according to Naruto's Nen reserves was confirmed when after increasing the amount of Nen he had, Naruto made a contract with Zeno again and it had been harder for the old man to try and break it. Naruto had used as many terms as he had the first time and had made them just about as complicated in order for a fair comparison so it was a reliable observation.

It was also proven by the fact that the contract that they had originally became harder for Zeno to try and break as well. Another thing was that the more terms a contract had the more Nen it took for it to be made but the more powerful it was. It was the same thing with the more complicated the terms were which meant that a very powerful contract should be made of a lot of complex terms.

Naruto had also found out what the punishment was for him breaking his own contract. It had been incredibly annoying to say the least. His Nen had been locked down for an entire month and moreover all the contracts that he had at the time were nulled. They weren't put on hold; they were completely wiped out meaning that Naruto had to make his contract with Zeno again. This was what led to him making his next discovery:

Making a contract with an exception to the terms stated in it was a lot more Nen consuming than making a normal contract. After finding this out he had then tried to make a contract with as many complex terms as he thought he could handle at the time and with an exception to it.

He had been promptly been knocked out cold for two weeks because he simply did not have enough Nen for the task. Zeno told him that it was a failsafe as much as a restriction; using all of your Nen was fatal and so was trying to use techniques that required more Nen than you actually had.

Another discovery they made was that the terms had to be balanced otherwise it was easy for the parties involved to break the contract and when they did break it the according punishment was not very powerful at all.

In other words the terms could not put one party at a massive advantage to the other or the contract wouldn't be very powerful binding wise and punishment wise. In a contract where there was an exchange of items after a service had been done the item or items stated had to be of a near value, whether money wise or importance wise to the one signing the contract, as the service being requested or the binding effect of the contract and the punishment effect for breaking it would, again, not be very powerful.

On the other hand Naruto had shown that when he successfully made a really complicated contract without being knocked out and someone broke it…

The results hadn't been pretty. The amount of Nen that had assaulted the person in question, a glory hunting bounty hunter that had tried to assault the estate, was immense. The keyword was 'tried' because one foreboding glare from Mike had the man pissing himself. Illumi had been nearby at the time and had taken the man instead of letting Mike eat him for the purpose of testing Naruto's abilities.

Naruto did not wish to do that again to someone.

The punishment had been devastating. The man had been a Nen user that according to Illumi had just about as much Nen as Naruto had but it didn't matter. The making of the contract itself had used a ridiculous amount of Nen.

Zeno told him after what was left of the man's remains, a few strands of hair and his right shoe along with a massive stain of blood, had been cleaned up that he figured the punishment was calculated as such:

It was the starting amount of Nen that had been spent in making the contract, which could be increased by adding more complex terms and/or exceptions, plus however many of the terms had been broken. This meant that if someone broke all of the terms stated the punishment would be doubly as powerful as the amount of Nen put in to making the contract. He wasn't sure how much power the exception stated in the contract contributed to it but it was still incredibly deadly.

Naruto vowed to keep messing around and experimenting with this amazing power he had been blessed with. He once again asked that Zeno would continue to help him in Nen training and the old man had agreed.

The old assassin told himself it was because he wanted, when the time came, for Naruto to make a powerful contract as possible with Alluka however a part of him realised that it wasn't just that. Ever since the blonde had come to live with them the house had felt more alive than Zeno could ever remember. Killua was more talkative as well as more driven in his training. He could tell that Silva and even Kikyo to an extent enjoyed the blonde's company. His seemingly innocent curiosity in all types of manners was endearing as was his open mind to pretty much anything. It could be attributed to his less than perfect moral compass that Naruto gotten along swimmingly well with himself, Killua, his parents and Kalluto as well as Alluka.

Naruto had met Alluka. After being told of Alluka's condition, that she was a natural Nen genius like he was and of how her power worked, he had insisted on meeting her. Naruto had never met someone like him so she had intrigued him. At first the others had been against it but Naruto calmly analysed that Alluka could not make requests to someone if she did not know their name. Naruto even questioned whether it was possible for him to meet Alluka under a false name and whether Alluka would still make requests of him.

Zeno and the others admitted that they had not thought about that possibility and it was then that Naruto had seen Illumi's cruelty first hand yet again. The young man had told him to introduce himself to Alluka under a random name and then had seemingly questioned to himself: if Alluka did make requests to the random name and Naruto denied four of them, would Naruto die or would any person who had that name die?

Naruto had refused to test it out, afraid of the consequences. It was not simply because there was a chance that he might die but also because if the second scenario was true the amount of casualties that he would, indirectly, be responsible for would be huge.

Instead he had not told his name to Alluka when meeting her. He and Killua would play with Alluka in her room or outside whenever no one else was around. It was strange that Alluka did not make requests of Killua when they were playing but both took that as a blessing and did question why it was. Alluka had gotten as attached to Naruto as she was to Killua. Even if she couldn't make requests to him like carrying her on his back or throwing her up high Naruto still did regardless. He enjoyed the chibi's company and found her to be endearing.

Killua had told Naruto that he was going to do whatever it took to protect Alluka and Naruto as his friend agreed that he would help too. This had solidified their friendship even further.

After all was said and done the whole family decided that it was finally time for Naruto to make the contract with Alluka. Naruto went in to Alluka's room after being told by Zeno what the terms were.

'Do not make requests of anyone unless told otherwise. In return you'll be allowed to have as much freedom as you want.'

It was exceedingly simple. However Naruto, just like Killua, gnashed their teeth at the wording. They were intending to have Alluka's freedom, of being able to go outside and playing as much as she wanted with her beloved brother, restricted so mercilessly? It made Naruto frown; this was not how he wanted to use his powers.

One could call him a hypocrite because previously he had also made contracts where someone's freedom or even life was at stake. However those people had been mafia thugs! They had been murderers, conmen, rapists and greedy assholes that did everything they did for power and money! Alluka was different; she was just an innocent child that had no blame in developing those powers, it wasn't her fault!

Naruto understood however just why the contract was worded so simply. Whilst the wording might've been simple it actually wasn't. The first phrase used the vague term 'anyone'. Naruto and the others had discovered that when vague wording that covered a wide range of things was used it counted as an incredibly complex term and thus it gave the contract a lot of power.

For example if Naruto was to make a contract with Killua that Killua could not eat chocolate-balls, his favourite, and in return Naruto would give him a chocolate milk carton, this meant that Killua could not have chocolate-balls but he could have any other form of chocolate.

However if Naruto worded the contract differently, saying that Killua could not have any chocolate and in return he would give him sweets, for example, then Killua could not have any chocolate. This did not only mean things that were only made out of chocolate, it even applied to things that only had the slightest trace of the sweet goodiness in it. No matter how little of it there was Killua could not eat them no matter what, no matter how hard he tried to struggle against the powerful force restricting him it was hopeless.

Killua had never felt as much despair. Seeing the state his friend was in Naruto had decided to null the contract. They had all discovered that Naruto could null a contract without having to break it but the punishment was not being able to use Nen for a week. In comparison to the month long ban it was much better.

So using a blanket term that could apply to a lot of things counted as a very powerful term, which in term would have a very powerful binding effect. However in this contract there were two 'blanket terms'. Freedom counted as a vague term too which meant that this contract was going to be very powerful. The use of an exception in the contract served to only make it even stronger.

So Naruto got to work. He sat down in front of Alluka and smiled at the curious look the chibi was giving him. Focusing and exercising his Nen Naruto activated his ability. In response the signature roll of parchment, bottle of ink and black quill appeared on the ground in front of him.

He quickly wrote down the contract on the parchment and looked over it just to make sure there were no mistakes. He doubled and even tripled checked it and it was then he was satisfied with it. He walked over to Alluka and placed the parchment in front of her, sitting himself by her side he spoke, "Alluka-chan, can you sign your name on this?" said toddler only tilted her head at him. Naruto at first had no idea how a two year old was going to sign her name but because they had discovered the following it did not matter.

When signing a contract it was not required for the other party to sign their name. An abbreviation or nickname would do. Even a false name would work. That was because the contract did not recognize who it was signed with by name, it recognized by the person's Nen. The person did not need to even be initiated in Nen, the moment they signified their acceptance of the terms the contract would take a bit of their Nen as a 'signature' and thus it would be formed. However the act of signing it was important because that was how his ability would store a tiny bit of Nen of the person in question which would be used to recognize them as the one mentioned in the contract. This meant that forging a signature was meaningless and that Naruto had to get the right person to actually sign the contract otherwise it wouldn't apply to them.

However Naruto had to sign his name on it. They had tried everything, from having him use a false name to nicknames or even having someone else write down their name in the space for Maker: and nothing had worked. Naruto had to be the one to sign and he had to sign his full name or the contract would not activate.

So he watched as Alluka scribbled down some gibberish, it didn't matter because the second the quill, which was held in her hand, had touched the parchment a bit of aura had been absorbed into the parchment. Using Gyo Naruto had been able to see it clearly.

Naruto took the contract from her hands and with a massive build-up of Nen his ability activated.

"Deal with the Devil: The Contractor activate!" With a huge amount of effort his ability took effect. The amount of Nen used was truly massive. It swirled around in the room in a torrent of white and black energy, making the lights blink and the walls tremble and circling the two children before it started being condensed and compressed into the roll of parchment in Naruto's hands and then disappeared after a few minutes. Outside of the room the rest of the family had watched the events that had occurred and Zeno immediately noted something.

The amount of Nen used had been perhaps twice as much as the contract that Naruto had made with the old man. Said contract also had a blanket term in it "any harm" and there was also an exception in it. But the amount of power used in the making of the contracts was completely different. Was it because Naruto had gotten stronger since making that one?

'No. When he had to remake that contract with the exception he had already gotten stronger. Since then he has not made such a huge amount of progress that it would lead to such a difference...'

Unbeknownst to Zeno and the others Naruto had perhaps discovered the most important rule to his ability. When he had activated it he wished, with all of his will and might, that the contract be as strong as possible for Alluka's sake and, like always, his Nen had replied. It had thus poured out as much aura into the making of the contract as it was safe for its wielder. Enough to make it as powerful as possible but not too much that it would have to knock out its wielder for his safety because he would've been using way too much aura and it could lead to his death.

So Naruto again found himself in a massive state of exhaustion after the activation. He blinked his eye lids sluggishly and felt someone pick him up with a vague sense of detachment. It was the old man that had gotten him into this mess. Unbidden a memory made its way to the forefront of Naruto's mind. This had happened before, right after making the contract with Zeno he had felt a massive wave of tiredness hit him and had fallen asleep shortly.

Naruto realised it was because back then he too had wished that the contract would be as powerful as possible, to save his own hide, but this time he wished so it would benefit someone else. His last thought before he went to sleep was:

Doing something for someone else or doing it for yourself; which one made it stronger?

So there ya have it. Naruto begins to question whether it's better to use the power he was blessed with for himself or for others.

Personally I'm pretty happy with how Naruto's ability worked out. I feel that it has a lot of potential but at the same time isn't just downright overpowered and I enjoyed making rules, requirements and exceptions to it but in return making his ability even stronger because he's using them. I'm aiming for this to be a smart story with smart fights and the like so I'll try my best to make it like that.

If you were wondering about the pacing thing I mentioned at the start, after reading this chapter you probably know what I meant. Like I said I'm not happy about it personally because I don't think I'm progressing enough with the story but at the same time I like writing in a detailed fashion, giving a lot of insight as to how characters think and react to situations, so I'm torn. Anyways lemme know what you think.

Lastly it would make me write a lot faster if I got at least ten reviews on this chap… ;)

See ya.
