We currently see Killua and Zushi in the arena, preparing to fight each other.

Commentator: "All right, everyone! This is the event you've all been waiting for! A unique match-up between two young boys who've both got something to prove!" The commentator said, hyping up Killua and Zushi

Commentator: "But dont underestimate these fighters! Both had strong showings in their first rounds and now they've jumped all the way up here to the 50th floor!" The commentator said as Killua and Zushi popped up on the big screen.

Commentator: "And now let's take a look at the big screen for the playback of those events!" The commentator said as Killuas first fight begins to play.

Commentator: "Killua beat his opponent in a flash!" The commentator said as the screen showed Killua one hitting his opponent.

Commentator: "One chop was all it took to knock him out!" The commentator said, now showing Zushis fight.

Commentator: "Zushi used martial arts to punish his opponent scoring a flawless knockout against a giant weighing over 200 kilograms!" The commentator said as the screen showed Zushi delivering a barrage of punches.

Commentator: "Okay now, everyone! Ready to press your wager buttons? Go on! Make your picks right now!" The commentator as everyone pushed one of the wager buttons.

Commentator: "All the bets are in, and we have a clear favorite! Zushi!" The commentator said, making Killua a bit mad.

Commentator: "Maybe his knowledge of martial arts has given him the edge!" The commentator said.

Zushi: 'This isn't good... Killua is mad.' Zushi thought to himself while crying anime tears.

Referee: "Three Rounds! Three minutes per round decided by points or K.O.! Begin!" The Referee said.

Zushi then got into his fighting stances.

Killua: 'I see. His stance doesn't leave many openings. He's trained hard to master it.' Killua thought to himself, commending Zushi.

Killua: 'But he doesn't stand a chance against me.' Killua thought to himself confidently as he walked toward Zushi.

Commentator: "Wow! Killua is walking boldly toward his opponent!" The commentator said.

Then, as Killua got closer to him, Zushi tried to punch him. But Killua just vanished behind him and chopped him in the neck.

Killua: 'Sorry, but I'm sticking to one chop per match 'til I reach the 150th floor.' Killua said as Zushi fell to the ground.

Referee: "A clean hit!" The referee said.

Commentator: "Killua has laid out another opponent with a single blow! A clean hit and a knockout earn him two points!" The commentator said as Killua began to walk away.

Commentator: "As you know under the points and knockout system, there are clean hits, critical hits, and knockdowns. Great attacks count as 'clean hits', with one point each. Superb attacks are 'critical hits', and are worth two points. Knocking your opponent down is one point. Collect ten points and you're awarded a technical knockout. Of course, if your opponent can't continue the fight after one hit you win by a knockout!" The commentator said, explaining the point and knockout system.

Killua: 'Pretty sure that chop ended it. Idiot.' Killua thought to himself.

Referee: "Can you fight?" The referee said as Zushi got up.

Zushi: "Yes! I'm all right!" Zushi said, shocking Killua.

Commentator: "He got up! Zushi will continue the match!" The commentator said.

Killua: 'Did I hold back too much?' Killua thought to himself while dodging Zushis attacks.

Killua then vanishes behind Zushi again and chops him in the neck.

Commentator: "He's taken another hit! Zushi is down!" The commentator says as Zushi gets up.

Commentator: "But he's getting up before the referee reaches him, meaning Killua won't be awarded the point!" The commentator said.

Killua: 'He's good. I'll have to change my tactics.' Killua thought to himself as Zushi got into his fighting stance.

Killua: 'But something's not right. That attack was so strong that even if I just grazed him, he'd be out cold.' Killua thought to himself, Thinking that zushi was hiding something.

Zushi: 'Unbelievable! Such awesome power and speed! At this rate, I won't stand a chance! But I've gotta try. I have to!' Zushi thought to himself as he got into another stance.

Then, Zushi stares at Killua with an angry-like look on his face. And after a few seconds, he starts using Ren. Scaring Killua shitless.

Killua then instinctively jumps back. But then, Zushi speaks up.

Wing: "Wing shouts, making everyone cover their ears.

-Cut to prisoner realm.-

We currently see you about to use White on Kalluto. Who scraped his knee while running earlier.

Over time, you got better at using White. To the point where you could actually use it instead of struggling to even make it. The only thing you had to work on was to make it heal better.

Kalluto: "Ow..." Kalluto said while holding his leg in pain.

Y/n: "Be more careful next time. You idiot." You said to Kalluto as you finished healing his knee.

Kalluto: "Don't call me an idiot big brother. It's mean." Kalluto said while pouting.

Y/n: "Alright, alright, You aren't an idiot..." You said to Kalluto while patting his head, making him instantly switch back to a happy mood.

Kalluto: "That's better!" Kalluto said while flashing a million-watt smile. Rivaling a certain girl with a horn.

Then suddenly, you and Kalluto hear the faint shout of someone. It isn't clear what it was saying, but you know that it was an angered shout.

Y/n: "You hear that?" You asked Kalluto while looking around.

Kalluto: "I do, but I dont know what it's saying." Kalluto said while looking around.

Y/n: "Well, it doesn't really matter. Wanna play?" You asked Kalluto accidentally.

You then realize what you said and turn bright red while covering your mouth. You dont know why or how that came out of your mouth, You never even played with any sort of toy before. But, you were glad you did. Because you got to see Kalluto's precious smile again.

Kalluto: "Yes! I'd love to!" Kalluto said excitedly while hugging you.

Kalluto had never played anything with anyone before. Not even with her parents or siblings. All he knew was assassination. And like Killua, he was getting sick of it. He just wanted to have a nice and happy family, where he could play games and have fun. And now that he was being offered the very thing he wanted, he was eager.

Y/n: "Alright then! What do you wanna play?" You said while looking down at him.

Kalluto: "Hmm... How about a race?" Kalluto suggested excitedly. Wanting to play his first game as soon as possible.

Y/n: "Sure." You said as you jumped away from him.

Kalluto: "Okay, 3...2...1... G-" But before he could finish, he gets cut off Satoru.

Satoru: "WAIT!" Satoru said, intervening with you and Kalluto.

You and Kalluto then look over at him, only to see a stern look on his face. Being worried, you try to calm him down.

Y/n: "H-Hey dad... You see, I and Kalluto are just having a fun little race, nothing more. So-" You then get cut off by him again.

Satoru: "Let me finish sir." He said with a stern look, before switching to a grin.

Satoru: "Dont go too far." Satoru said while grinning.

You and Kalluto breathe a sigh of relief before looking back at each other while smiling.

Kalluto: "GO!" Kalluto said as he started running, making you do the same.

Satoru: 'Man. Those two... I'll protect them with my life.' Satoru said while smiling, appreciating the family he was blessed with.

-Cut to Killua -

Everything was silent after Wing shouted, It was just so out of nowhere that everyone was too stunned to speak. Then, the commentator begins to speak.

Commentator: "So... a very loud and overenthusiastic spectator has temporarily interrupted the fight but let's see if we can get it going again! Come on folks, whaddya say?" The commentator said, trying to get everyone to forget about what just happened.

-Cut to Gon after Killua's fight.-

We currently see Gon sitting on a bench, alone and bored out of his mind. Then, Killua comes out of the elevator next to him.

Gon: "Oh, hey! Killua! Over here!" Gon said, making Killua turn toward him.

Gon: "Check it out! I got 60 thousand. How about you?" Gon asked, starting a conversation.

Gon: "It took you longer to get here than I expected." Gon said.

Killua: "Yeah, I ran into some trouble." Killua said while walking away.

Gon: "So, was Zushi pretty strong? Or what?" Gon asked.

Killua: "No way... No. He has potential. He'll be strong one day. For now, anyway, he's just target practice for me. Punches that weak, I could knock him around easily." Killua said, then he stopped walking.

Killua: "But I couldn't beat him." Killua said, catching Gon by surprise.

Killua: "I won the match. TKO by points. But still, I just couldn't knock him out. Also... When he changed his stance, I got this really creepy feeling, like when I faced my brother." Killua said, thinking back to Illumi and Zushi.

Killua: "I dont know what it was, but it felt... dangerous. It's gotta be some kind of technique. I heard his master call it 'Ren'." Killua said.

-Flashback.-

Zushi: "Please! Forgive me, Master!" Zushi said while bowing.

Wing: "I thought I made it clear to you that you were not supposed to use Ren yet, Zushi." Wing said.

Zushi: "Im sorry! It's just... He-he was so strong, I couldn't help myself." Zushi said.

Wing: "Yes. I understand the urge to win. But you have another goal. A goal that lies beyond this. At the top floor of this tower." Wing said as Zushi raised his head.

Wing: "Dont focus too much on simply winning, Zushi. Impatience will only erode your potential." Wing said.

Zushi: "Osu!" Zushi said while getting up.

Wing: "You must be prepared to lose a thousand times while you're here." Wing said.

Zushi: "Osu!" Zushi said, taking Wing's words to heart.

-Flashback over.-

Gon: "So, he's not supposed to use Ren? Until he gets all the way up to the top floor, I mean." Gon asked.

Gon: "Thats where the strongest fighters are, right? At the top?" Gon asked.

Killua: "Gon. We need to change our plan." Killua said, completely ignoring Gon's question.

Killua: "I say we shoot for the top floor. No longer will we stand In Y/n's shadow! He has super cool and powerful abilities, what do we have? All we got is physical strength and speed! We can't repel our opponents so fast that their heads explode, We can't FLY, We can't pull off the amazing and outrageous feats that Y/n has, hell, The reason he got trapped in the first place was that WE were too weak! We can't let something like that happen ever again!" Killua said.

After you got sealed the in prison realm, Killua realized how truly weak he is compared to You or any of the Zoldycks. He couldn't even resist Ren or against Illumi. Nor could he help you against Silva. He was helpless, and he didn't like it one bit. And he has been bottling up the anger and frustration ever since.

And during his rant on how strong you were, he released it. He was even pissed even before the whole sealing happened. During the Hunter Exam, when he discovered that You were leaps and bounds more powerful than them, and could stand up to Netero, even though you were the same age as him pissed him off.

So, he wanted to get as strong as possible, as fast as possible. And the heavens arena was the perfect place to do that.

Gon: "I agree. I also want to be as strong as Y/n is. I dont want to be constantly protected and saved by him any longer." Gon said while clenching fists.

In their opinion, You have done so much for them. And it was time that they do something for you.

-Timeskip 1 day.-

Commentator: "Killua defeats another opponent with one chop for a knockout win!" The commentator said.

Commentator: "Now there's action over in the next arena. Gon has knocked out another opponent with a single push!" The commentator said, showing Gon's fight.

Commentator: "Each of them has won six consecutive matches over the past three days, and they've reached the hundreds without even a scratch to show for it!" The commentator said.

Commentator: "Killua's Chop. And Gon's push. They seem unstoppable. But can they keep it up?" The commentator said while showing Gon and Killua on a big screen.

Commentator: "But the real question is who if anyone, can stop them?" The commentator asked.

-Timeskip a couple of hours.-

Gon: "Yay! Our own room!" Gon said while jumping on the bed.

Gon: "We're not gonna have to worry about money and lodging anymore!" Gon said.

Killua: "I wouldn't be so sure. Tey to remember, drop below the 100th floor and you lose the room. There's a huge difference between getting here and staying here on the 100th floor. It's a real threshold." Killua said.

Killua: "Beyond the 100th floor, you get special treatment. And so, naturally, no one wants to lose their standing. There are people here who'll do anything it takes to stay on the 100th floor." Killua said as he stood up.

Killua: "You can waste a lot of time on 'em. Time we dont have right now. So be careful, Gon." Killua said.

We currently cut to the next day, seeing Gon win another match.

Commentator: "Gon wins another match with a single push!" The commentator said.

Killua: 'Guess I didn't need to worry about him.' Killua thought to himself while smiling.

Gon and Killua just kept on winning and winning their matches, All by using their traditional chop and push. And we currently see them getting their prize money.

Staffer: "Your prize money has been deposited into your account." The staffer said.

Gon: "You were right. I've never seen so many zeroes before. It felt like yesterday when I was totally broke." Gon said while looking at his balance.

Killua: "I'm a little bit annoyed. The first time I was here, It took me two whole months to reach floor 150. You, on the other hand..." Killua started.

Gon: "Yeah, but back then, you were only six." Gon retorted.

Killua: "Well... Yeah, there's that." Killua responded.

Gon: "Oh, by the way, I saw Zushi on TV earlier." Gon said.

Killua: "Yeah, so did I. He's still on the 50th floor." Killua said as he and Gon stopped walking.

Gon: "I wonder what that 'Ren' thing was that creeped you out. And why." Gon said.

Killua: "Maybe we'll meet some opponents higher up who use it." Killua suggested.

Gon: "Or maybe... It'd be faster to just ask Zushi!" Gon said.

-Cut to Zushi.-

Zushi: "Ren is one of the Four Exercises. The Four Exercises are fundamental to all martial arts. They instill discipline and develop character. "Learn Ten, know Zetsu, through Ren to attain Hatsu!" And all of that is how you train for Nen! Thats it!" Zushi said, explaining Nen in the most nonsensical way possible.

Killua: "Start making sense!" Killua shouted angrily, not understanding a thing.

Wing: "Zushi..." Wing said, making Gon and Killua turn toward him.

Wing: "Are you certain that you're sufficiently qualified to be teaching others?" Wing said.

Wing: "Now, Gon, Killua... An old proverb warns: that it's possible a smattering of knowledge may not reduce one's ignorance, but increase it." Wing said.

Killua: "So, you're saying that a little knowledge is a dangerous thing? Thanks for the tip, but I really want to learn this. Because I'm convinced it's behind my brother's and Y/n's powers." Killua responded.

Wing: "You say that your brother and this 'Y/n'... can use Nen?" Wing asked.

Killua: "I need to understand what Nen and Ren even mean! And not just halfway. I need to know it! If you're willing to teach me, I won't try to figure it out for myself." Killua said.

Wing: "Well, in that case..." Wing said before cutting himself off for a second.

Wing: "Let's adjourn to my room." Wing said as he walked toward his room.

Gon: 'Yes! Finally, I can learn something that can give me a potential chance to stand alongside Y/n instead of behind him!' Gon thought to himself happily.

Killua: 'Oh yeah! Once Y/n gets unsealed, He'll be so surprised!' Killua said, imagining a shocked looked on your face while smiling.

And as they were walking away, we see the same cloaked figure behind a wall, overhearing everything.

???: 'So they're gonna learn Nen huh? Not like it matters. Not only am I far superior to everyone in this tower full of weaklings, but Im also a floor master.' The cloaked figure thought to himself.

???: 'I do really need to find a way to get to the Prison realm. After all...

I need to seal Netero."
