Thank you everyone who's been reading my story so far. I hope you enjoy this new version, and I hope it reaches your standards.

Killua was walking around the forest with his favorite sibling, Alluka, when he suddenly ran off into the woods. Confused, Killua chased after him. They just kept running and running, Killua's child body growing tired from the long distance.

Then Alluka stopped. That in and of itself wasn't the problem Killua had with the entire thing. No, it was the fact that he stopped in front of Mike, the second scariest creature Killua ever had the pleasure of meeting, one rank below his father.

Mike seemed to have curled himself around a body, and Killua had thought that another person must have snuck into the forest on this side of the wall and Mike had decided to snack on them like the good guard dog he was. That thought was pushed to the back of his mind when Alluka decided to work his way past Mike's body and towards the person laying between his paws.

Cue Killua's internal freakout.

Alluka, poor, innocent, helpless Alluka was a hair's breadth away from the second most dangerous creature ever, all so she could see a mutilated corpse and destroy the peaceful image Killua had so painstakingly formed for her of a perfect world.

When he poked at it Killua almost died right then and there.

Alluka did his best to pick up the body and managed to drag it a little ways out of Mike's paws, and that's when Killua saw it wasn't a grown man who was killed by the guard dog, but a young boy. A young boy with bright yellow hair and torn up clothes. A boy with blood staining his yellow hair and dying clothes a bright shade of red..

"Killua, help me! He's heavy!" Alluka whined, and Killua automatically went over to help. A quick pull drew the boy up and into Killua's arms. With the boy fully situated Killua noticed the boy's weight, or lack thereof.

The boy was lighter than even Alluka, even though he looked about the same age as Killua himself. A ten year old isn't supposed to be as light as a seven year old.

Hopefully Silva would be willing to allow this kid medical attention, or Killua had no clue what might happen to the boy. There were cuts decorating his body in a gruesome work of art. It looked as though the boy had been hunted down for a long while before finally succumbing to Mike's greatness. If he was able to draw it out for as long as it looked like he did, this kid is pretty impressive. Sure, Killua could probably last that long, but he was a trained assassin, so that was a bit different. This kid had to have been leading an interesting life before ending up at Mike's mercy.

It's even more impressive that Mike didn't just decide to kill the kid right once he caught him. Maybe Mike gained respect for this little boy who was able to run from him for so long. It's far-fetched, but this is Mike. Everything is weird around him.

Killua took care not to think about how his little sister was able to switch into a personality that could grant any wish or how he was being trained by the greatest assassins known to man-kind for multiple generations. He didn't want to be the thing that attracted the weirdness. Who knows what that would mean for his future.

Maybe this kid would be a good addition to the family. He's cute enough that Kikyo, Killua's mother, might just take him in. She seems to love cute things with a burning passion, that's the main reason Alluka was added to the family. She also took it upon herself to make all of the cute boys of the family act feminine. She tried with Killua, but he tore up the dresses she'd stuff him into.

Hopefully this poor kid won't have to go through that the same way Alluka and Kalluto have to. Killua's been the only one to successfully escape. Illumi just seemed to take it all in stride, so it hadn't affected his personality to the point of changing all of his mannerisms and the way he wanted to be addressed.

Killua was watching his two little sisters playing underneath him. He was sitting in a tree and trying to read but kept being distracted by something they were doing. Actually, he was making sure they didn't get too… excited.

Though his parents didn't know it, Naruto - his newest little sister - was very strong and could do something very interesting with his nen. It's kinda like Alluka and Nanika - also something his parents don't know about - but not exactly. While Nanika is within Alluka and can grant wishes for a price, Naruto is able to change how his body looks and it's abilities. It's pretty amazing.

"Killua-niisan! Come play!" Naruto shouted up at him.

"One moment imouto!" He shouted back. Killua jumped down from his resting spot and joined in their game of hide and seek. Killua thought it was majorly unfair for him and Alluka, but he never complained. Well, he doesn't complain anymore. The one time he told Naruto off for transforming his ears and nose into that of a fox, he got growled at with claws at his throat. Definitely not something he wanted repeated.

"Nii-san, you're it!" Naruto said, running off into the trees; Alluka going in a different direction. Killua started his counting to 50. By the time he was done, no one was in sight. Knowing not to head in the directions they had started off by going in because there was no way either of them would be in that direction, Killua started walking to his left - towards the main road.

And there was Alluka talking with Canary, the female butler apprentice. Wait, no. Not Alluka. Nanika.

Killua intervened, not wanting Canary to know what was going on. "Hey, we're playing right now! There's no need to bother Canary! Come on, Nanika-chan!" Killua shouted out, interrupting Nanika mid-sentence and successfully distracting Canary, if only a little.

"Alright, Killua-nii-san! Catch Naruto for me?" Nanika asked, turning her power to Killua and away from the poor butler.

"Of course!" Killua said, smiling kindly. "Canary, please don't tell anyone what you saw. Thanks!" Killua said before running off to find the fox-eared boy. And yes, he was going to have his ears out, listening for Killua and making it even harder than it already was. Well, good thing they like training!

"What do you mean you're locking Alluka up? The only reason all those people died was because of you! Not her. Nanika was only doing what she's supposed to do when you messed everything up!" Killua had to force himself to stay calm during the entire confrontation with his parents. They were somehow able to find out about Nanika, and now wanted to lock the two up. Sure, Kikyo promised to make sure everything would be comfortable and she'd have toys and a lot of other comfy things, but that didn't change the fact that she'd be locked up for a large amount of her life.

"That doesn't matter, Killua. Alluka's dangerous. Why knows what could happen to the family if someone we know makes a powerful wish. There's a chance he might destroy our family. I won't take that risk, even if it means putting my precious Alluka in his room forever."

"We could just teach her how to use her powers! It could be so much better if she can control it, not just lock it away!" Killua argued. There was no way his mom would be allowed to do this.

"Killua, you will listen to me. As your mother I order you to go to your room and calm yourself down. Now go." Kikyo ended the conversation before Killua was able to attack her either verbally or physically. Killua glared at her, swearing to himself he would get stronger. Strong enough to protect his sisters. Throwing one last glance at the locked steel door, he grabbed Naruto's hand and walked out of the room.

"Nii-san, what are we going to do? I don't want Alluka or Nanika to be locked in there. It doesn't look fun, even with those stuffed animals. They'll get bored or something. And I can't play with them if they're locked up in there. We're gonna break them out, right?" It was tempting. Oh so tempting just to burst into that room and kill everyone who tried to stop him, but Silva was still stronger than both Killua and Naruto combined. Sure, Naruto had gotten a hold of his transformations and was able to do almost anything physical, but Silva was still the greatest assassin ever, and Killua wasn't experienced enough to face him.

"We will, but not yet. Both of us still need to get stronger." Killua hardened his resolve before heading out into the forest, Naruto following him. He'd have to get Naruto to go all out against him if either of them were hoping for any sort of improvement.

They had to kill the world's greatest assassin, after all.

Two years later

"Naruto, we're going to take the hunter exams." Killua said, interrupting Naruto's focus on catching a bird. Not just any bird, one of the birds that managed to survive within the Zoldyck forest with Mike on watch. They seem to have developed some sort of power that could prevent them from getting caught or eaten, thus making it far more difficult to capture.

Naruto's fox ears perked up as the bird flew away, scared by Killua's entrance.

"You mean those things that are supposed to be really difficult to pass?" He tilted his head as the ears disappeared, looking like they'd never been there in the first place. Killua nodded, serious for once.

"We're going to test our skills against other people besides the family. We know everyone's attacks and patterns already, so any sort of challenge could be a good change of pace. It might help our development better, and make it so we can use different fighting styles after meeting people who are well matched against us. What do you say? Coming with?"

"Yes! Yes, yes, yes! I finally get to see the outside world again! It's been sooo loong!" Naruto's fox features seemed to sharpen during his excitement. The whiskers elongating and seeming to form off of his face, the structure of his bones sharpening and giving his chin a more pointed look, eyes shifting to a golden color and becoming slitted in shape. His happy grin more predatory than friendly.

These changes were normal when Naruto was happy, like his powers were coming into use all on their own without Naruto's notice. It was cute but at the same time caused Killua to worry about Naruto's safety. After all, if someone besides Killua and Alluka saw this they could relay the information to the main family and Naruto could get locked up.

"Okay! Pack up some stuff and we'll head over to the front gate in a little bit. Just make sure you don't use any of your powers at all during the trip or the actual exam. People might still be watching us." He paused to let the words sink in. Naruto in his hyper state takes time to understand serious things. Once he calmed down - though it was just slightly - he continued. "Now, go get ready you slow poke!" He shouted, laughing again as Naruto scampered out of the room, skidding on the ground. Right once he couldn't hear his sister anymore, Killua thoughts took on a serious side. Mom's going to hate me...

After a very interesting confrontation with Kikyo that ended in a violent episode for Killua the two sibling stood in front of the gates leading to the outside world. Mike was waiting for them, seemingly for a send off like he does with Silva, but hasn't ever done with Killua. Naruto turned out to be a perfect playmate for the giant dog, one that was fast enough to play and durable enough to get tossed around lightly (by the dog's standards. It was still enough to break a tree trunk and leave Killua more than a little worried).

Naruto gave a few excited yells as Killua placed his hands on the door, ready to push and test his current strength. The door opened and Killua placed extra force into his arms and pushed it, sending the heavy doors fully open.

"Bye bye, Mike! Naruto shouted before scurrying through the open gate followed by Killua. The two waved goodbye to the gate keeper before heading down the mountain.

Killua had done a small amount of research on the exams, finding out exactly where the exams were taking place and how to get into them without going into detail on what each exam could be about. It's more fun to be surprised by what was happening in the moment than having it spoiled before even starting.

And he wanted to have Fun.
