Discaimer: As you all already know, I just own my OC, Hitomi. Hunter X Hunter, on the other hand, belongs to Yoshihiro Togashi.

Chapter 14: Heavens Arena x To the Top x What's Nen?

"It's just the three of us now," Gon told them. "So? What do you wanna do?"

"Isn't it obvious?" Killua asked. "We've gotta start training!"

"Huh? I thought we'd do something fun."

"If you think that suicide is what you call 'fun', go ahead," Hitomi said, facepalming. "Forget the six months, you won't even touch him in a decade!"

Gon looked at them, cluelessly. Killua, meanwhile, took a stick and draw Hisoka and Hanzo, near to each other.

"Let's put it simple. This is Hisoka and his is Hanzo. If the distance between them represents the difference in their fighting ability, then I would put you..." he said, before drawing a long, long line. After a few meters, he shouted. "... right here! And that's being really generous!"

"Then, where would you put you, Killua?!" he shouted, annoyed.

He seemed to think about it a little bit, before drawing himself in the middle of the line. He smirked, proud of himself. And that's when he realized Hitomi drawing herself a little ahead him.

"Then, there I am," she said, proudly. Killua's eyebrow twitched a little.

"Then, I should put me here," he said, doing the same.

She glared at him and put herself before him once again, making Killua do the same as her. Gon smiled nervously, staring at the huge cloud of dust they had made.

"Umm..." he said, sweatdropping. "Guys?"

At the calling of their friend, they both stopped to see what had they done. The two kids were pointing at the same spot, a few meters ahead Hisoka.

"If only it was true..." Hitomi murmured.

After a while discussing about it, the three decided to go to the Heavens Arena, a place where they could train and get money at the same time.

Hitomi stood in front of the huge man, who was supposed to be her opponent. The guy just raised an eyebrow in confusion.

"A little girl?" he said, not believing it. "Are you serious?"

"I don't think I need to, old man," she teased.

"The purpose of the first floor match is to evaluate each of your skill levels," the referee explained. "You have a three minute time limit to demonstrate how strong you really are."

"Three minutes? Maybe three seconds," he said.

"My thoughts exactly…" Hitomi murmured, before raising her thumb and her index finger. "I'll make it easy for you. I'll use just these two fingers."

"Don't kid with me," he smirked. "Well, let's play then."

The man started to run towards her and she raised her right hand.

One…

Two…

Once he reached her, she flicked his forehead. The fighter flew backwards and collided painfully with the wall.

Three.

"You were right," she grinned, "Three seconds."

She turned around to face the referee, who was the only person in the whole stadium to be quiet.

"You may advance to the 50th floor," he said, giving her a ticket.

She smiled, before making her way to the boys, who were going to the same floor. They three made a high-five.

"Osu!"

They all turned to see a small boy, who they had seen lately. He, too, advanced to the 50th floor.

The elevator girl continued talking, but no one was listening at her. The four boys just continued talking to each other.

"My name is Zushi," the little boy said. "What are your names?"

"I'm Gon, nice to meet you."

"I'm Killua," he introduced himself.

"Hitomi," she smiled politely.

"Osu, nice to meet you all!" he replied.

Finishing her long talk, the woman turned around to them.

"… So, do you understand?"

"Yes!" they all said in union.

However, she was well aware that they hadn't heard one word of the speech she had given them. Once outside, Zushi turned around smiling at all of them.

"I watched the three of your matches," he said. "You guys are amazing!"

"Look who's talking," Killua encouraged. "You're strong too."

"We're all in the same level!" Gon said.

Zushi, however, raised his hands on defense. "No. I've still a long way to go," he said. "By the way, which school of martial arts do you follow?"

The three looked at each other.

"Osu!" he said. "I practice Shingen-ryu Martial Arts!"

"Well, to be honest…" Hitomi scratched the back of her head. "No one."

"Huh?! You mean you got this good without anyone teaching you?!" he exclaimed, in huge surprise. "Osu! I am a little shocked. I have more to learn than I thought."

Hitomi's eyebrow twitched. Osu again… she wondered how many times he had spluttered that word.

Her chain of thoughts got cut once they heard someone clapping behind them. They turned around to see a man with glasses. He was Zushi's master.

"You obviously remembered what I told you," he said, before looking at the other kids. "We haven't met, did we?"

"Oh, these are Hitomi-san, Gon-san and Killua-san," Zushi introduced them.

"It's a pleasure," he said. "My name is Wing."

"Osu!" Gon instantly said.

"O-Osu!" Killua said, a little insecure.

Hitomi raised an eyebrow at both of them. Wing, on the other hand, just smiled at them kindly.

"I didn't think there would be other kids competing here besides Zushi," he told them. "You must be quite accomplished if you've managed to get to this far. You should always remember to take care of yourself and your opponent's body."

He gave Zushi his prize and then told them that they could get it in the counter to cash their tickets.

"Osu!" Gon and Killua said at the same time.

And after that, the three of them started to walk away.

"This 'osu' thing is contagious," Killua commented.

"Yeah," Hitomi said, irritated. "And annoying too."

"The money hasn't changed either. That's what you get on the first floor, whether you win or lose," Killua commented, looking at the little money they had won. "After that, you get nothing if you lose. If you win, on the 50th floor you'll get around 50,000 jenny. After the 100th it's one million jenny and beyond the 150th it's over ten million."

They all looked at him, surprised at the huge amount of money they could earn.

"But you said you reached the 200th floor last time!" Hitomi exclaimed.

"You got that far?!" Zushi yelled.

Hitomi sweatdropped. They all were looking at them at the moment.

"Well, to be honest, I actually quit after the 190th floor," he said and started to think. "I guess I won… 200 million."

"What did you do with all that money?" Gon asked, as shocked as the other two.

"That was almost four years ago! You didn't think I have anything left, did you?" he looked at them, like they were nuts. "I spent all of it on snacks."

Their faces fell, and couldn't say anything else.

"Hey you little kids!" a voice said behind them. "What are you doing like you're a bunch of big shots?"

Gon, as well as the guys, got surprised by seeing each other. They were the Amori Brothers, from the Hunter Exam.

Hitomi and Killua sighed, in annoyment.

"What are we gonna do now, bro?" the youngest asked.

"I was your idea to come over here and teach these conceited kids a lesson!"

"Conceited kids?" Killua said, as he and Hitomi turned around. "Are you talking about us?"

"So you are going to teach us a lesson?" Hitomi smirked. "It will be interesting…"

But they all ran away.

"… Maybe not, then," she completed her sentence, annoyed.

"Oh my, this place sure isn't what it used to be," Killua said. "Not if losers like that can get to this level. Getting off the 50th shouldn't be too tough."

Then a female voice sounded in the speakers. It said that the next match was between Killua and Zushi, what made the youngest pale at it.

"Well, we'll be off," Killua said, standing up.

"Best of luck to the both of you," Gon said.

"I'll wait for you two in the lobby on the 60th floor," he said, before walking away.

After the two boys were gone, both Gon and Hitomi sweatdropped.

"No sense of niceness," Hitomi murmured.

Gon nodded, smiling nervously.

"Attention, the next battle will be between the Amori Brothers in one team and Gon-sama, Hitomi-sama and Kei-sama. Please report to Ring C on the 58th floor."

Gon and Hitomi looked at each other and grinned. The Amori Brothers just paled.

"W-What?!" the participant, Kei, shouted in shock.

Gon smiled sheepishly at him and then to the Amori Brothers. They had all collided with the wall, thrown by both Gon and Hitomi. The other one, however, didn't even have the chance to fight. It was all over in a flash.

That's when they both felt something… unusual from the floor beneath them. Where Killua and Zushi were fighting.

They looked at each other and nodded.

When all was over, they started to run. Once they found an unscratched Killua, both kids sighed in relief.

"It seemed to take longer to finish than you thought," Gon commented.

"Yeah," Hitomi teased. "What happened? I thought you were invincible! Was Zushi that strong?"

"I had a little hard time, but Zushi is talented for sure and he'll be good someday. But to me his technique is full of holes," he replied. "But it was still pretty hard to take him down. Not only that… There was a moment when Zushi changed his stance. I got this bad feeling, just like when my brother confronted me."

Hitomi and Gon glanced at each other.

"We felt it," she said. "From the floor above yours. It felt a little… dangerous."

"I overheard his master say something about Ren," Killua told them.

The boy told them when he overheard Zushi and Wing's conversation and narrowed her eyes.

"I think we need to have a change of plans!" Killua declared. "I'm going for one thing… the top floor."

The blonde girl flicked her enemy once again, making him fly backwards, just like the first one she had encountered. The screen divided, showing another two kids who had just defeated their opponents as well.

"It took only three days for the newcomers Gon, Killua and Hitomi to reach the 150th floor! The three are undefeated after seven matches! What's even more remarkable is that, so far, none of their opponents have managed to score a single point against either of them! How long will this good luck last?"

Annoyed, Killua turned off the television and sighed.

"It's not about luck, we're just better than them!" he murmured.

"Really? I do remember someone telling us that the guys in the 100th floor were tough," Hitomi said, turning over a page of the book she was reading. "You made us all worry for nothing."

"But, you know, I'm a little vexed," he placed his arms behind his head. "The first time I was here it took me almost two months to get up to the 150th floor, yet…"

"You were six," she didn't take her gaze out of her book.

Killua looked at her, she wasn't paying him attention at all. He looked at Gon, who wasn't doing that either. He was like… panicking over the money he won.

But it got stolen by the other boy.

"Let me borrow it for a little while," he asked.

"How come?" he asked, in confusion. "Didn't you have the same amount deposited into your account?"

"Yeah, but I spent it!"

For the first time, Hitomi looked at him. She raised an eyebrow, before he pointed at a long line of boxes.

"I was wondering about those since I came in…" the girl murmured. "May I know what are they?"

"Chocolate Robots," he replied, in cat-mode. "It was on sale, so I thought I'd stock up."

They both sweatdropped.

"I think you've bought enough chocolate for now!" Gon shouted. "So give me my money ba-!"

He got cut when Killua put a pillow in his face. Annoyed, Hitomi sighed and moved out the way, sitting next to the boxes. She tried to read in peace, but it was fruitless.

"I said I'll give it back later!" Killua shouted.

"No way!"

Gon pushed the boy out of him, and he landed right in front of the boxes. Irritated, she hit the boxes with her hand, making all of them fall on Killua. Hitomi stole back Gon's money.

He glared her from beneath the chocolates.

"You're annoying," she just replied, it giving back to the other boy.

"Oh. Thanks, Hitomi," he said, before scolding his male friend. "You shouldn't waste your money, Killua."

"Don't call Chocolate Robots a waste of money!" he yelled.

Now Killua was pissed off. He jumped from where he was and ran to the boy. He stood behind him and grabbed both his hands and legs, resting his back on the bed.

"Ouch, ouch, ouch!" he shouted in pain. "I give up, I give up!"

He released the boy, making him stay there, with his face in the pillow. Killua stared at him for a while and sighed.

"How do you expect to make it to the 200th floor in the shape you're in?" he said, "Hisoka is even stronger than me, you know?"

"Yeah, I know that. But I'm not sure what kind of training I need," he murmured, before remembering something. He shot of the bed. "Killua... How good is Zushi?"

Hitomi's attention draw out the book, as she closed it. She looked at Killua, waiting for him to answer Gon's question.

"The guy is still trying to get of the 50-somethingth floor," he told them. "I told you before, but that is his level at the moment."

"But wasn't it hard to take him down?" Hitomi jumped in the conversation. He nodded.

"Yeah, during our match he kept getting back up no matter how many times I hit him, so I got a little ticked off," he recounted. "Finally, I hit him with some serious force and, even though I won for by a TKO, he stood up again. That was beyond the level of what one could manage with willpower."

"Maybe it has something to do with Ren, you know, that thing that Wing mentioned," Gon commented.

"That means he has some technique that Gon and I could sense from our floor," Hitomi said.

"I don't know, but as we move up to the higher floors, we'll probably face more people like that," Killua said, putting his hand under his chin in deep thought. "Maybe we'll find out if we fight them."

"Forget it, if that technique is really powerful we will be dead before we even lay a finger on them," she waved her hand at him. "Can't we just ask Zushi?"

"Oh, yeah!" he exclaimed, not having thought about that possibility.

They found Zushi not long after. He gladly accepted to explain that Ren thing to them, but that wasn't the problem...

"Ren is one of the four exercises, and the four exercises are fundamental to all martial arts to instill discipline and develop character. Learn Ten, know Zetsu and through Ren attain Hatsu! That's how you train for Nen!" he said, before bowing. "Now you know!"

They blinked at him and stared at the boy blankly, cluelessly.

"Nen?" Gon repeated.

"What the hell is Nen?" Hitomi murmured.

"That doesn't make any sense!" Killua snapped, making both Gon and Hitomi back away a little.

"It doesn't?" Zushi didn't even react to Killua outburst. "Then I'll try explaining it again, listen carefully. Ren is one of the four exercises, and the four exercises are-"

But then Wing appeared from nowhere and made him stop in mid sentence. Zushi bowed in greeting at his master.

"Gon-kun, Killua-kun, Hitomi-chan, there's an old cautionary proverb warning that a smattering of knowledge may leave you wallowing in greater ignorance," he told them.

"But little knowledge can be as dangerous as that," Hitomi replied. "I mean, if the enemy knows more than you, you're as good as dead. Isn't it like that?"

"I wanna know this Nen stuff right now," Killua added. "Even if you don't tell us, I'll find out without fail. But I don't want to get stuck wallowing around in ignorance. So if you agree to teach us, we won't be forced to go and learn what it is by myself."

"Please, Wing-san," Gon pleaded. "Killua, Hitomi and I came to train."

"Osu!" Gon and Killua bowed.

"O-Osu," Hitomi said, a little uncomfortable.

Wing sighed, giving up.

"I understand. Please, follow me."

The three children walked off Wing's place. Gon waved at him happily, before catching up his two friends with a grin in his face.

"Wing-san is really amazing," he told them. "Zushi is lucky to have such a master."

"But what he told us earlier, that was a lie," Killua said, Hitomi nodded.

"A lie?"

"What he said sounded right and the demonstration of his power was very real, but..."

"Have you seen Zushi's face at that moment?" Hitomi completed. "The guy is on it, and he knew that Wing was telling us a lie."

Gon thought about it for a moment.

"But, why would he tell us such a lie?" Gon murmured.

"This Nen stuff is something dangerous. "I think that Wing is afraid of what we could do with it, " Hitomi sighed, before murmuring sarcastically, "He trust us way a lot..."

"But, before we leave Heavens Arena, we're gonna have to figure out what Nen really is!" Killua declared.

"It does bug me a little after all," Killua murmured, waiting in front of the elevator to get to the 200th floor. "It took me two years to get to the 200th floor. On the other hand, you two..."

"Killua, you were six," Hitomi reminded him, annoyed.

"I know, but still..."

The elevator opened, revealing the same girl who had been annoyed by them before, making her back away slightly.

Once inside it, they stood in silence.

"I wonder what the 200th floor is like!" Gon exclaimed.

"I don't know," Killua admitted. "When I got this far last time I didn't bother to register. I just left and went back home."

"Oh well," Hitomi sighed, before directing to the elevator girl. "Miss, do you know-?"

"I don't know," she cut her, dryly.

"So you don't know? How useless," Killua said.

Realizing what was happening, Hitomi took a couple of steps closer to the door. Meanwhile, Gon tried to shut Killua up.

"This place is really going downhill. They don't even bother training their employees anymore!" he continued.

"Killua!" Gon tried to stop him.

"If they can't, they could have at least made a better choice on the looks..."

"Killua!"

Hitomi's eyes flew open. "Uh-oh," she murmured.

Killua shut up, looking at Hitomi cluelessly. He then realized what she meant when he noticed the elevator girl turning around, angered.

Hitomi looked away, nonchalantly, as she hit them. Once the elevator stopped, she got out it as quickly as she could.

She turned around to see both of her friends and started to laugh hard. She put a hand over her hurting stomach. Their faces were a complete mess.

"It isn't funny!" Killua shouted, annoyed.

"It is!" she replied.

After calming down, the three friends made their way in the corridor. However, after a while, they felt something... strange.

"Can you two feel it?" Killua asked.

"Yeah, this feeling is..." Gon trailed.

"This has to be that Nen thing," Hitomi concluded. "It was worth coming to the 200th floor after all."

They nodded at each other, and started to walk once again. After they took two steps or so, a huge wave of wind made them move back.

"Hey! We know you're there, why don't you come out and face us?!" Killua yelled.

From the corner, a worker from the Heavens Arena appeared. She looked at them, with a emotionless expression in her face, and pointed at some direction.

"You must be Gon-sama, Hitomi-sama and Killua-sama," she said. "The reception desk is right over there. You have until the end of the day to register for your matches. Please be aware that once it's past midnight, you'll no longer be allowed to register."

A person stepped closer and stood at her side. The three kids looked at him and gaped in huge surprise.

"The clown... great," Hitomi rolled her eyes.

"Hisoka!" Gon exclaimed.

"What are you doing here?!" Killua asked.

"What am I doing here? Such an expected reaction," Hisoka replied, holding a card. "Here is my answer... I came here because the cards told me to. They told me that our fates were intertwined."

Their faces fell in disbelief and disgust, at the same time.

"Just kidding. Of course it wasn't fate, I planned the whole thing," he told them. "You used the internet to purchase your airship tickets, didn't you? It's easy to search that thing and find out who is going to be when and where. After that, I boarded my private airship, arrived here and waited for you."

"So you're stalking us!" Killua and Hitomi shouted in unison.

"Don't be silly," he smirked. "I'm a regular tenant here on the 200th floor and have been for a long time now. So, as someone who knows his way around here, let me give you a little piece of advice. It's too early for you to step on this floor... turn back!"

The pressure got stronger, at the point that the kids weren't able to stand on their feet anymore. After that, Hisoka sat in the floor, saying that he would wait for when they were ready.

"Come back another time," he said. "It's just too soon for you now."

"No way, we've come this far and we're not leaving!" Killua shouted.

They tried to even stood in their feet, but it was fruitless. That's when Wing arrived at the place.

"Stop trying to force yourselves. You're totally unguarded against his Nen," he told them. "It's like you've wandered into the snowstorm naked and don't understand why it's so cold. You might die if you kept forcing your body and spirit."

"See that?!" Hitomi yelled, pointing at Hisoka, "That's more that a thought, you lying bastard!"

"I've decided to teach you true Nen," Wing replied, he looked at Hisoka. "So, let us retreat from here now."

Hisoka stopped and smirked. Meanwhile, Gon asked the worker what happened if they didn't register by midnight. She told them that Hitomi and Gon would have to start all over again, but Killua would be banned because the last time he didn't bother to register.

"If we leave here with you now, can we come back here within the midnight?" Killua asked Wing.

"That will depend on you," he told them.

Several roses that Wing threw stabbed the vase, using his Nen.

"What was that bull about burning your spirit?" Killua said, irritated. "What kind of master are you, anyway, lying to innocent kids?"

"Innocent?" Hitomi raised an eyebrow. "Well, Gon at least..."

"Killua-kun, you seem to be quite passionate about learning Nen," Wing commented. "Any particular reason?"

"Because it explains the secret of my brother's power," he said.

"Your brother uses Nen?" Wing asked in surprise.

"Yeah, I'm sure he does," he nodded.

The man looked at them for a moment, with a serious expression.

"Okay, I'll teach you assuming you understand the dark side to Nen as well," he said. "Nen is the ability to control at will the life energy which flows through your body. Ten is a technique that will help you retain that energy within your body. Zetsu is a technique for shutting off your aura. And Ren is for generating your aure beyond ordinary amount."

And Wing continued explaining about that Nen stuff, and Hitomi found it really interesting. It was a miracle that she pay attention in all his speech without even spacing out.

"Do you understand?" he said, finishing his explanation.

"Yeah, I understand three things," Killua said. "One, how powerful true Nen is. Two, we won't be able to win without it from here on out. And three, you are a tricky bastard!"

"My thoughts exactly..." Hitomi murmured.

Wing just smiled, nervously, before continuing.

"There are only two ways to awaken it: slowly... or by force," he told them.

"And by the looks, we'll be forced to awaken it by force," Hitomi muttered, bored. He just looked at her, before resuming his explanation.

"Zushi took the slow path, he is a quick learner who is very dedicated to his training so he was able to master Ten in a relatively short period of time. It took him six months," he said. "But we don't have enough time. So, as Hitomi-chan said, we'll have to awaken it by force."

"And then we can make it on time?" Killua asked.

"That depends on whether you can master Ten or not," he said. "I'm going to attempt to transmit my aura into you. This is known as Hatsu, similar to what I used earlier."

"Great," Hitomi rolled her eyes. "So that means we'll get killed by our so-loved teacher instead of the clown?"

"I'm going to hold back, of course, but that doesn't mean it's not going to be rough," he chucked at her. "By sending my aure through your bodies, I'll force open your nodes. Now, please remove your jackets and turn your backs toward me."

Hitomi nodded and took her hoodie off. She felt a warmth in her back, even though she knew that Wing wasn't even touching her. Wing first opened Killua and Gon's nodes and instantly after Hitomi's.

She felt like something hit her in the back, nearly making her lose her balance. Hitomi then felt something... strange. It was like something warm inside her was escaping for her.

She stared in amazement at the aura around her. She had never felt anything like it.

"At this rate, your life's energy will soon be depleted," Wing said, "and when it's gone, you'll be too exhausted to even stand."

"How can you say something like this that calmly!" the girl shouted, panicking a little.

"Listen to me!" he said. "Just imagine you're containing your aura. Now close your eyes. Stand however is easiest for you. Feel the aura as the very blood coursing through your veins and now try slowing it down!"

They did as they were told and, much in Wing surprise, the three of them mastered the aura in a matter of a few seconds.

"Now slowly open your eyes," he instructed. "Tell me how you feel."

"I feel like I'm soaked in lukewarm viscous fluid," Gon answered.

"Like I'm being surrounded by a wave of stream," Hitomi murmured.

"It's like I'm wearing clothes that don't weigh anything," Killua said.

"Try to hold on those first impressions. Once you internalize them, you'll be able to use Ten in your sleep," Wing said, after activating his own Nen. "This time, I'm going to attack you with a malicious aura. If you can withstand this, you'll be ready to past Hisoka. Here it comes."

They all nodded, ready for that.

Hisoka smirked, when he looked at the three kids in front of him, who had passed through his wall of Nen.

"Welcome to the 200th floor. Looks like you won't need to be initiated," Hisoka said, before looking directly to Gon. "I can guess why you decided to come here. You're here to train yourself to fight me, aren't you?"

"I didn't know you were gonna show up here," Gon admitted. "Guess that saves me time."

"Don't get too cocky just because you've learned Ten. Nen has many facets," he said, before standing up. "Quite frankly, I don't plan on fighting you anytime soon. But if you can win one match on this floor I'll reconsider it."

And he walked away. The three friends made it on time and succeed in registering. The woman who worked in the reception tried to tell them all the new things in the 200th floor, but none of them were interesting at all.

"Well, we just came for training, didn't we?" Hitomi said.

But then, they felt someone behind them. As the other two did, Hitomi looked over her shoulder, just to see three men.

"These weirdos want to fight us… they look boring," she thought. "Wait, what if I make them wait, until their deadline? I don't know when it is, but…"

"I'm ready for a march anytime," Gon told her.

"In the first days of April," Hitomi said and looked over her shoulder, smirking.

They glared at her, she had been right. Their deadline was before then.

Killua shook his head. Even though Wing told them to not fight until two months, they both were going to do so before then.

They walked to Gon's room and found out a sign on it.

"Match date confirmed; March 11th at 3:00 PM at the 225th Floor Arena."

"That's tomorrow!" Killua exclaimed.

"I probably won't win this one, but that's okay," he said, his Nen increasing. "I wanna find out what I'm capable of with this power."

"It's not okay," Hitomi facepalmed. "Now I'm really worried."

End of the chapter... Maybe it was a little too long? Well, sorry...
