Mika's POV

We were in the elevator again and the same woman from before was there. She had red hair and light blue eyes with a dark yellow, dark blue, white and pink uniform on with the same hat and fist in the middle of the shirt.

"Congratulations you guys, all of you get to go to the one hundredth floor, which is an honor." She told us.

"It's not that big a deal." Killua says leaning back on the way with his arms under his head.

"Yeah." Gon agrees. "We wanna go all the way to the top!" He tells her.

She looks back at us and clasps her hands together. "All those who reach the hundredth floor are untitled to their own private room. The prize money goes up by a lot." She says.

"Hey, we know." Killua says in a bored tone.

"Private rooms huh?" Gon asks.

"I guess that means no more pillow fights huh, Gon?" Killua says and I sweat drop and the woman anime falls.

"You guys had pillow fights?" I say.

"Yeah!" Gon tell me. "It was really fun."

"Listen! If I were you I wouldn't kid around! You'll be up against some pretty tough opponent now!" She tells us. "As I was saying earlier, the emendations get a lot better once you reach the hundredth floor, and that's exactly why all the people who make it there will do everything they can to stay! Some competitors will bend the rules with all kinds of nasty tricks! The longer they've been at this level the tougher they get. You can't even compare them to those guys on the fiftieth floor."

Gon looks at Killua. "Killua, is that true?" He asked.

"Well yeah." He says nonchalantly.

"Well good! That's what I was hoping for!" Gon says happily. "I was starting to worry that we might have come all the way here for nothing."

Killua looks at us and smiles. "It's no big deal; last time I was here I had no trouble winning at this level."

She looks at Killua confused. "The last time?"

"Yeah, when I was six." Killua says.

"When you were six?!" She yells and the elevator door opens and we look at her.

"Thank you." Killua and I say and we both smile at her reaction.

"Yeah.." Gon says and she was on the ground and we all exit out.

"You're welcome." She says completely exhausted. "I look forward to serving you again soon." The doors then close and we stop moving.

"Let's go see our rooms." I say and we walk to our rooms they were near each other. Gon runs into his room.

"We're up so high! Look how far we can see!" Gon yells happily and I sit on his bed as Killua walks over to the window near Gon.

"Yeah." He says. "What that woman said was true, you know. It's a big change once you go to the ninetieth floor to the hundredth. Everything here is different; some of these guys who've been up here for a really long time are prepared to do anything to stay right where they are. I know, I was joking about it, but we need to be careful. We're on our way to the top and we're not going to let anyone stop us."

We nod and head to our other rooms. My room looked identical to Gon's. I then went to sleep thinking about the next match I was having tomorrow.

Time skip time for Gon's match~

The crowd was even larger than before and Gon was up against a man with dark brown skin, black hair (it was in an afro and he was in a karate gi. We couldn't hear what they were saying but let's just say that it took one push to defeat his opponent.

"Gon wins!" The referee says and everyone starts cheering for Gon.

"Hn, I guess I was worried for nothing." Killua says.

"We're just flying by this." I tell Killua and he nods and I lean back. "I wonder what the two hundredth floor is like."

"I guess we'll just have to wait and find out." He tells me.

"Killua report to the Ring for your next match!" A person says and he gets up.

"On my way." Killua says.

"Good luck." I tell him and he walks down to the Ring. He was up against a medium sized man, with average muscles and dark red hair.

"Let the match begin!" The referee says and the man tries to punch Killua but he dodges and takes a crop near his neck and he falls face forward.

"The match is over Killua wins!" The referee says.

"Mika please report to the ring for your match." A voice tells me and I walk down. I was against a tall man with large muscles, blue eyes and dark brown hair.

"Begin!" The referee yells and he tries to punch me but I catch his arm and then he tries to kick me but I end up catching his leg.

"Bye." I said and broke all the bones and pressed on his neck and he was down. "I don't think I'll ever get tired of breaking someone's bones. It's so fun." I say with a smile.

"Mika wins her match!" The referee yells and I head out of the match.

Time skip~

We were all sitting in Gon's room listening to the TV. It was about all of us.

"It took only three days for newcomers Gon, Killua and Mika to reach the one hundredth and fiftieth floor. They're both 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?" Killua then turns of the TV.

"It's not about luck." He says. "We're just better than them." He then leans back on the bed that Gon and I were sitting on. "I can hardly believe the last time I was here it took almost two whole months just to get up to the hundredth and fiftieth floor." He then looks at us. "Are you listening?!"

Gon was looking at the money he had received. "Tens! Hundreds! Thousands! Millions! What?! How much is this anyway?! I've never seen a number this big! I mean, a few days ago I was pretty much broke!" Killua then takes Gon's money account paper.

"Let me borrow it, okay?" He asked him smiling.

"Hey... How come? Didn't you have the same amount deposited into your account?" Gon asks him.

Killua smiles sheepishly. "Yeah, but I spent it."

"You spent it?! On what?!" Gon yelled and Killua pointed to multiple boxes of chocolate robots.

"I was wondering where all that came from." Gon and I said.

"And what is it?" Gon asked Killua.

"They're chocolate robots." Killua says with a cat's smile. "They were on sale so I'd thought I'd stock up."

Gon gave him an annoyed look and pointed at the boxes angrily. "I think you've already bought enough chocolate, for now! So..." Killua then threw a pillow on Gon's face and I jumped on the bed watching Gon and Killua fight. "I want my money back!" Killua then pushed the pillow hard on Gon's face.

"Don't worry I'll give it back later!" Killua said and Gon grabbed him by the arms and threw him off the bed but Killua landed on his knees and not on his precious candy. Gon then ran after him and pushed him into some of the boxes and took his money back and Killua tried to grab him but missed as all the boxes fell on him.

Gon then tucked his money in his shirt. "I won't let you waste any more money Killua." Killua then jumped out of the boxes and ran towards Gon.

"Hey! Don't call chocolate robots a waste of money!" He then went around Gon and pulled both his hands behind his back and kicked him in the back. "Take it back!"

"Okay! I take it back!" Gon yelled and flopped on the bed, his head on the pillow.

"Boys.." I said while I just stared at them. I then got back on the bed and sat crisscrossed like Killua.

"How do you expect to make it to the top floor in the shape you're in." Gon let out a sigh in exhaustion. "Hisoka's even stronger than me, you know."

Gon opened his eyes. "Yeah, know that. But I'm not sure what kind of training I'd need..." He then closed his eyes. "Killua, Mika? What do you think Zushi's up to?"

"I don't know." We said. "He's probably trying to get off the fiftieth floor."

"From what I could tell he still isn't ready to move up at the moment." Killua finished.

"Yeah, but didn't you say it was hard to take him down?" Gon asked and Killua nodded and looked away.

"During our match.. No matter how many times I hit him, he kept getting back up. It was so annoying! Finally I hit him as hard as I could. Somehow he has this power to never back down."

Gon then got up. "Maybe it has something to do with Ren like that thing Wing mentioned?"

"Or Nen." I said.

"Nen?" They asked me. "What's that?"

"It's just something that Hisoka mentioned to me during our match." I told them.

"Do you think they're some kind of new technique?" Gon asked.

"I don't know." We said to him.

"But as we level up to the higher floors we'll face more people who can do stuff like this." Killua then put his hand on his chin. "We gotta find out how."

Gon then smiled at us. "Well, then why don't we go and find Zushi and ask him?"

"Okay!" Killua said.

"But do you think we'll really understand what he's about to explain to us?" I asked them.

"Who cares! Let's go!" Killua yelled and we ran out the door and got on the elevator and went down to the fiftieth floor.

Time skip~

We finally found Zushi and asked him about it.

"Ren is one of the four exercises, and the four exercises are fundamental to all martial arts, to use discipline and to show character. Learn Ten, know Zetsu and through Ren attain Hatsu! That's how you train for Nen! Now you know." He then bowed and we gave him blank looks as Gon had multiple sweat drops on his head.

"Nen?" Killua asked.

"Isn't that what Mika was talking about?" Gon said.

"What's Nen?" I asked.

"That doesn't make any sense!" Killua yelled.

Zushi looked up at us. "What? It doesn't? Then I'll try explaining it again. Listen carefully, Ren is one of the four exercises and the four exercises a-"

"Zushi that's enough." Wing said and walked towards us. "Only those who have mastered the training are qualified to teach it to others."

Zushi bowed. "Of course, I'm sorry master."

Wing then looked at us. "Hello again, Gon, Killua, Mika. There's an old cessionary proverb warning that a smattering of knowledge can leave you wallowing in greater ignorance, have you heard it?"

"I've heard that a lot of knowledge can be a dangerous thing, but I want to know exactly want Nen is. I really want to learn. Even if you don't tell us, we're still gonna try and find out. But I don't want to get stuck wallowing around in ignorance. So if you agree to teach me I won't have to force myself to learn about it myself."

"And I wanna learn to!" Gon said. "One of the reasons we came here is to learn more."

"So do I." I said

"Osu!" We said together bowing.

Wing let out a sigh. "I understand, follow me." We then got out of our bow and followed him to his training room. There was a board on it and it was almost night. The sun was falling down and we could only see the colors of the sunset.

"Nen is a power that inflames our souls and is expressed by strength of will. The training to obtain Nen is comprised of four exercises we call these four exercises the four fundamentals and they are: Ten, Zetsu, Ren and finally, Hatsu. Let me explain each of them in details first with Ten which focuses the mind and helps you concentrate on your inner self helping you concentrate on your goal.

"Following that Zetsu, helps you put that goal into world." Zushi seemed surprised with Wing's explanations. He's lying to us. Killua and I noticed. "Ren helps you intensify your will and Hatsu puts it into action. Zetsu's Ren or his will to win is what intimidated you, Killua. I think that explains it, now allow me to demonstrate. Killua will you please stand up?"

Killua stood up and looked at Wing. "My mind will be filled of thoughts of killing you, is that okay?"

We gave him a blank look. This'll be interesting.

"Well it's just an exercise, so go ahead." Killua told him.

"I'll do it in the proper order. Ten." He gets into a strange stance. "Now Zetsu. You can say it loud or to yourself it doesn't matter." He then releases his stance and looks at Killua. "I am going to, kill you." Then there was a flash of anger and hatred coming from Wing and everyone could feel it. After Wing was done Killua wasn't in his spot from before. I looked back and saw that Killua was on the right side of the wall with his legs on the side of two different walls and him beside the ceiling. Gon didn't know where he was yet but he was looking around.

"So that was Ren. With enough strength and focus your will or Ren becomes action or Hatsu. This is how you intimidate others." Gon then looks up. "Sometimes it can make your opponent so scared that they'll surrender before the fight even begins. However this can often lead to dangerous misconceptions about how powerful you actually are and cause you to lose focus. To be truly effective, Ren requires unwavering the mind. All four of you are ready. I will then now try to focus the mind and ignite your spirits. If you want to learn Ren you must first dedicate to mastering Ten. In order to do that you won't feel intimidated by others." Killua jumped down.

"Thanks a lot Master Wing." Gon said and I looked out the window and it was nighttime. We then walk out and Gon waves goodbye while Killua and I just continue to walk. Gon then says "Osu!" and bows. "I really like Master Wing, Zushi's so lucky."

"You know he was lying to us, right?" We ask him and Gon stops moving.

"He was?" Gon asked.

"Everything he taught us today sounded right and the demonstration of his power was very real, but it didn't explain why Zushi kept getting up during our fight. They're hiding something." Killua explains.

"Plus, didn't you see how Zushi reacted when Wing was teaching us? They both know." I ask him.

"You could be right." Gon said. "But I don't get it! Why'd do you think they'd lied to us?"

"Cause Nen must be something very powerful." Killua says.

"And dangerous. They don't trust us enough to explain it." I tell them.

"Before we leave Heavens Arena we're gonna have to figure it out."

Time skip~

"This is unbelievable! Gon, Killua and Mika have all won their first matches on the one hundred and ninetieth floor! They move up to the two hundredth floor undefeated and they've only been here a week." The woman said by the elevator we were on the one hundred and ninetieth floor waiting for the elevator to come up.

"You know this kind of bugs me." Killua said.

"What?" I asked while Gon said. "Huh?"

"It took me two years to get to the two hundredth floor and you've done it in a week." Killua said.

"Well, sorry." I said.

"Come on get real Killua!" Gon said. "You were only six years old at the time right?!"

"I know but still..."

The elevator dinged.

"Finally." Gon and I said.

"Anyone going up?" The same woman from before said and screamed when she saw us.

"Hey." Killua said.

"Hello." Gon said and I waved. We then got into the elevator.

"I wonder what the two hundredth floors like!" Gon said excitedly.

"Me too." I said.

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

"Excuse me, could you tell us what it's like up th-" Gon tried to ask her.

"I don't know." She told us.

"What?" Gon said surprised.

"I said I don't know!" She yelled.

"Come on what kind of elevator operator are you?" Killua said rudely.

"Killua." Gon said.

"She's gonna get pissed." I said.

He shrugged. "This place is really going down hill, they don't even bother training their employees anymore.'

"Sh! That's enough." Gon said.

"If they're not going to be smart you'd think they would be good looking." Continued.

"Killua!' Gon and I yelled and she turned around.

"I don't have to take this!!" She yelled and I ducked as she punched Killua and Gon in the face. The elevator dinged and I got out of the elevator first and then the boys with marks on their faces.

"I guess I should of stopped huh?" Killua asked and we nodded and walked forward. But we immediately stopped because there was a pressure. "Do you feel that?"

We nodded. "It's a good thing we made it to this floor someone down this hallway is using Nen."

"What now?" Gon asked.

"I say we keep moving, if Wing isn't going to tell us what Nen really is then we'll just have to figure it out for ourselves. Let's do it, come on." Killua said.

"I have a bad feeling about this." I told them.

"We'll just have to keep going." Killua said and we made steps forward down the hall where one light was flickering on and off. After a few steps the light broke and the room started feeling heavy and there was a large pressure against us. We stopped walking.

"No! I can't move! I don't want to go any further." Gon said and Killua moved around.

"Hey! We know you're there! Why don't you come out and face us!" Killua yelled and a woman with short dark brown hair and blue eyes walked out with a purple, dark yellow, blue and white uniform. She was smiling and wearing lipstick.

"You must be the newcomers Gon, Killua and Mika." She told us and she pointed down the hall. "In case you're wondering the reception desk is over there. You have until the end of the day to register for you matches. Please be aware that once it's past midnight you'll no longer be allowed to register, oh one more thing, from the two hundredth floor up weapons are allowed in the matches so if you have any, feel free to use them."

"This energy?" Gon asked. "Is it coming from her?"

"I can't tell." Killua and I said.

"You should also know that this level prize money is no longer awarded if you win. Here, you fight only for honor and reputation. I hope I made myself sufficiently clear." Then a hand came beside her and we all gasped.

Hisoka walked out of the hall with dark red hair instead of blue.

"Hisoka! What are you doing here?!" Killua yelled and Hisoka laughed.

"What am I doing here?" He asked putting his hand on his face. "Is that really all you've got to say to me?"

Killua blushed and Hisoka looked at us. "To tell you the truth." He lifted up a card. It was a red ace. "I came here because the cards told me to." We gave him a confused look. "They told me that our fates were intertwined." We then gave Hisoka a grossed out look and the lady moved far away from him. "Of course, I'm only joking." He then started messing with his hair.

"Fate has actually nothing to do with it. You used the internet to purchase your airship tickets, so all I had to was search for your names and ta da! I knew exactly where you were going and when I found out that you were coming here to Heavens Arena, I just couldn't resist!" He said still staring at us. "I boarded my private airship and arrived here well ahead of you. "

"You told me to come here." I said to him.

"Of course, I was planning on meeting you here anyway." He told me. "I was just surprised that you came here with them. Nice look."

I looked at my blue hair falling down to my shoulder and gave him a blank look. "Thanks."

"So you're stalking us?!" Killua yelled at him.

"Don't be silly willies I'm a regular tenant here on the two hundredth floor, have been for a long time, now. So aside from that, I'm a person that knows his way around here. So I'll give you a little piece of advice, for right now, the three of you aren't ready." He then flung his hand back and the woman's hat flew back and the pressure was too much that we fell back on the floor 10 feet away and landed on our feet.

Hisoka then sat down. "As for when you'll be ready. It's really hard to say. So take my advice, come back another time, and try again."

"No way! We've come this far and we're not leaving!" Killua yelled at him.

"Can you get pass me?" Hisoka asked us and more pressure was added on and this time we didn't land on our feet.

"He's right." A voice said and we looked back and saw Wing. "You don't have nearly enough training to overcome his Nen. It's like you've wandered naked into a snowstorm and you have no idea where you are and how to get back home. If you stay here much longer you're not going to survive."

Killua then pointed at Hisoka angrily. "Is this what Nen is?! All he's gotta do is hold up his hand and we can't move a muscle?!"

"I've decided to teach you the true meaning of Nen. But right now we need to get you three out of here and quick." I looked back at Hisoka and saw a blue glow come off from him and he put his arm down and looked at me. His Nen was gone and we got back up.

"Yeah, but we've got to register for our matches just by midnight! What happens if we don't?!" Gon asked the woman.

"Well, then you'll have to work your way back up from the first floor again. However..." She stopped.

"Yeah what?" Gon asked.

"Since Killua didn't register the last time he was here on the two hundredth floor, and if he fails to do it a second time, he will be considered as someone who lacks the necessary commitment and he'll be banned from ever competing here again." She explained.

"No way!" Gon said and we looked back at Wing.

"If we leave here with you, right now, can we come back in time to register, or not?" Killua and I asked him.

"That will depend on you." The clock then struck 8:30. We don't have a lot of time. We then got up and followed Wing back to his training room. He was throwing flowers at a pot and they stayed there making marks in the glass.

"This is Nen." Wing said and Killua glared at him.

"Tell me! Why should we believe you now?!" He yelled. "What kind of Master are you anyway?! Lying to kids who just want to learn?!"

"Killua, you're more passionate about learning Nen then any student I've ever had. Any particular reason?" He asked him.

"Yeah." Killua said. "Because I think my older brother used it against me."

"Your brother uses Nen?" Wing asked him.

"Yeah, I'm sure he does." Killua answered.

"Plus that guy, Hisoka, he showed me Nen in a fight once." I told Wing.

Wing looked down and then back at us. "Okay I'll teach you, as long as you understand that there's a dark side to Nen as well. Nen is the ability to control at will, the life energy, or what some people call Aura. Which flows through your body. We all emanate a limited amount of this Aura. The average person is not even aware of it in their bodies. Ten is the technique that helps you retain that energy within your body strengthen and helping it maintain its youthful vitality. Zetsu is the technique for containing your Aura, it's best for concealing your presence and recovering from injury or exhaustion and finally Ren is the technique for maximizing your Aura."

There was then a presence of something around us. The boys also noticed it.

"Tell me, can you feel that?" He asked us.

"Yeah, it's like pressure." Killua and I said.

"But it's not scary or anything" Gon said.

"It's letting you know that I'm not a treat." He explained to us. "Aura is life energy that is produced by our bodies, which is why it is most effective against other human beings. It can be used for good or for evil. If you attack someone who does not know how to defend themselves you can easily kill them with your Aura alone. There's only one way to protect yourself against an attack from a Nen-User and is to become a Nen-User yourself."

"I think I get it." Killua said. "It's like fighting fire with fire." Gon and I nod.

"Defend with Ten, use your Aura to block the Aura of your enemy." He then started moving towards the wall. "Because if you don't." There was another feeling of Aura as he put his arm on the wall and the wind picked up around the room and the wall shattered. "Your body will shatter into pieces."

We looked at him shocked. "Just like that." Gon said.

"Do you understand?" Wing asked us and Killua answered.

"Yeah, I understand three things." He said.

"Really? What three things?" Wing asked and Killua began counting to three.

"One, real Nen is powerful than anything else. Two, we won't be able to win without it from here on out and three, I still can't believe you lied to us the first time!" He screamed and Wing smiled.

"Right."

The clock then said 8:55. Will we be able to make it in time?
