We currently see Leorio, Kurapika, Killua, and Gon walking down the street after leaving Kukuroo mountain. Gon was currently holding on to the prison realm.

As they were walking, they were talking about possible ways to get you out of there.

Gon: "Maybe we could break it?" Gon suggested, thinking that breaking the prison realm will just automatically release you.

Kurapika: "I dont think that's a good idea. And we don't even have the power to break it anyway. The thing is really durable." Kurapika said, disagreeing with Gon.

Leorio: "Maybe there's some type of key out that can unlock it?" Leorio suggested.

Killua: "I dont see a keyhole anywhere on this." Killua responded.

Gon: "DAMMIT! How are we supposed to get Y/n out if we know nothing about this stupid thing!" Gon said angrily.

Kurapika: "Here's an idea, maybe it depends on Y/n." Kurapika suggested, confusing everyone.

Kurapika: "Let me explain, Maybe instead of us releasing him, Y/n has to will himself to come out." Kurapika suggested.

Killua: "Are you saying that only Y/n has the power to get out?" Killua asked.

Kurapika: "Exactly. Keep in mind, we have no idea what's going on in there. Maybe he's training his butt off to get out." Kurapika said, making the atmosphere around them a bit happier.

Leorio: "You could be right!" Leorio said cheerfully.

Kurapika: "Dont gets your hopes up yet. We just have to wait, and see what happens." Kurapika said.

-Cut to Y/n-

You were currently shirtless, drenched in sweat, and dead tired. Turns out, learning these techniques would be harder than You thought.

Y/n: "Holy crap... This is so damn hard... How did you manage to do this??" You asked through exhausted breaths.

Satoru: "Well, I was stuck here for many years. So I had a lot of time to create and refine these abilities." Satoru said while grinning smugly, pissing you off.

Y/n: "I didn't think sending my energy into other people would be so hard." You said while getting up, preparing to try again.

To use white, you have to send your energy into other people to heal. It was difficult to learn because it required not only an incredible amount of focus, It also required that you maintain that focus for a certain amount of time. It was like trying to hold weights while standing on an exercise ball, on one leg.

Of course, Satoru could do this without breaking a sweat. Which he constantly mocked you about.

Satoru: "Wooow. Didn't know healing was sooo hard to do. It's really easy. But, I guess that you're just incapable of doing it. What a shame." Satoru said mockingly.

Y/n: "DAMMIT OLD MAN! QUIT MAKING FUN OF ME!" You shouted angrily, making Him and Kalluto laugh.

You then angrily put your shirt back on and sat down. Wanting to think about a way to use White easier.

Kalluto: 'This is what a family should be.' Kalluto thought to himself while smiling.

Kalluto: 'Wait. Once we get out of here, what am I gonna do?' Kalluto thought to himself, forgetting that he was disowned.

Kalluto had nowhere to go. He was basically disowned and kicked out of the Zoldyck family. Once he got out in the real world, he would be homeless. Yes, he may be an assassin, but he had no idea how buying houses worked. He didn't know about the essentials for survival, so he was panicking a bit now.

Satoru notices this and looked toward Kalluto with a concerned expression.

Satoru: "Kalluto, something wrong?" Satoru asked, making you look at Kalluto.

Y/n: "You okay? It looks like your thinking about something." You asked, also concerned about the person you now considered a friend.

Kalluto: "I-Its just that... Before I was sealed in here, I was disowned. And once we get out of here, I'll basically be homeless." Kalluto said while looking down.

You and Satoru then looked at each other, You then nodded, and Satoru looked back at Kalluto.

Satoru: "Well Kalluto, how about I take you in?" Satoru asked, making Kalluto widen his eyes.

Kalluto: "You'd really do that?" Kalluto asked while tearing up slightly.

Satoru: "Yeah! What's the harm in having more family members? It's a bit boring have just me and Y/n." Satoru said.

Y/n: "Yeah. And I've always wanted a sibling!" You said while smiling.

Kalluto was moved to tears because he never really liked his family. And after everything that happened with Silva was the boiling point. And after seeing you and Satoru interact, how a father and son SHOULD interact, he deep down wanted to be a part of that.

And now that he was offered to be a part of a new family, a better family, he was ecstatic.

Kalluto: "YES!" Kalluto shouted happily while tackling you into a hug, crying into your shirt.

Y/n: "Geez little brother... Cool it with the waterworks." You said while smiling and stroking his hair, referring to him as your sibling.

Satoru: "Then it's official. From this day forward, You shall be known as " Satoru said happily.

-Timeskip 1 day.-

Gon's group of friends have officially split up. Leorio went home to study to be a doctor. Kurapika went off to find an employer willing to employ him as a hunter. And they also make time to find information on the Prison realm and ways to release you.

And after Kurapika explained what Hisoka said, they all planned on meeting back up in Yorknew City on September first.

And now, In the present time, we see Gon and Killua discussing something.

Gon: "Guess it's just You, Me, and Y/n now, Killua. So? What next?" Gon asked, being completely clueless on what to do next.

Killua: "You seriously have to ask me that? We've gotta start training." Killua said.

Gon: "Oh. For what? What not have fun?" Gon said, completely forgetting about Hisoka and You.

Killua: "You remember what you told me about a second ago? You think you can free Y/n AND punch Hisoka in the face without training?" Killua said angrily.

Killua: "THAT'D TAKE TEN YEARS! FORGET ABOUT SIX MONTHS!" Killua shouted angrily as he aggressively poked Gon in the face.

Gon: "Okay." Gon said meekly.

Killua: "Here. I'll break it down for you." Killua said as he grabbed a stick.

Killua: "This is Hisoka and this is Hanzo." Killua said as he drew Hisoka and Hanzo in the dirt.

Gon: "Right, I'm with you." Gon said.

Killua: "If this is the strength gap between Hisoka and Hanzo... The gap between you and Hisoka is..." Killua said as he began to draw a massive Line in the dirt.

Killua: "This wide! And I'm being generous!" Killua shouted from a few meters away.

Gon: "Thats just mean!" Gon grumbled angrily.

Gon: "Okay, then how far apart are you?" Gon asked, annoyed that he's being underestimated so heavily.

Killua: "Who, me? Well, probably here..." Killua said as he drew a tiny line in the dirt.

Killua: 'Im so humble!' Killua thought to himself.

Gon: "Oh... So Hanzo's the stronger one? Wait..." Gon said, before thinking for a bit.

Killua: "What is it?" Killua asked, not prepared for the oncoming compliment.

Gon: "You really are awesome, Killua!" Gon said, making Killua embarrassed.

Killua: "Knock it off, all right? It's embarrassing... And Im not nearly as awesome as Y/n..." Killua said mumbled while looking away.

Gon: "It's just... I don't know how to tell the difference in strength between my opponent and me." Gon said.

Killua: "It doesn't really matter, dummy. I'm only estimating, anyway." Killua said as he walked away.

Killua: "Besides, you get the general idea, right?" Killua asked as Gon began to follow him.

Killua: "And with experience, your estimates will become more accurate. But the stronger someone is, the better they can hide that strength. So it's not a method that I'd recommend." Killua said.

Gon: "Okay, I won't." Gon responded.

Killua: "Point is... Hisoka's really strong." Killua said.

Gon: "Yeah." Gon responded.

Killia: "With just six months, we're gonna need to get real creative. And once Y/n comes back, We're gonna wanna look like completely different people!" Killua said, wanting to get stronger to impress you.

Gon: "Yeah!" Gon said cheerfully as he raised his fist in the air.

Killua: "Hey... got any money?" Killua asked.

Gon: "I'm a little low, actually." Gon responded sheepishly.

Killua: "I dont have much either. But there's a place Where we can make ourselves some money and train at the same time." Killua said while smirking.

Gon: "Make money while we're training?" Gon asked, not knowing of a place that they can do that.

Killua: "At the Heavens Arena." Killua said.

Gon: "Heavens Arena?" Gon asked.

Killua: "Yeah! I'll explain later. But we really ought to get going now!" Killua said as he ran into the building he and Gon were standing in front of.

Gon: "Right!" Gon said, following behind Killua.

-Cut to Heavens Arena.-

Killua: "Gon!" Killua said, making Gon pay attention.

Gon: "This is a really long line. Is everyone going to Heaven Arena?" Gon asked.

Killua: "There aren't any rules to worry about. Not like there were for the Hunter Exam. You just gotta knock your opponent out." Killua explained.

Killua: "The higher you go, the more prize money you make. If you want to earn a living with your fists, this is as good as it gets!" Killua says.

Receptionist: "Welcome to Heavens Arena." She said as he handed Gon and Killua a form.

Receptionist: "Now, if you wouldn't mind filling out this form..." She said as they filled out the form.

Receptionist: "Killua Zoldyck, you're number 2054. Gon Freecss, you are 2055. On the first arena floor, they'll be calling you by your number, so try not to forget it. Please go on ahead." She explained as she pointed them to the right.

Gon: "Wow..!" Gon said in awe of the sight in front of him.

There were little 1v1's going on, arm wrestling, and other stuff.

Killua: "It's been a while, but this place hasn't changed." Killua said.

Gon: "Wait... You mean you've neem here before?" Gon asked.

Killua: "Yeah. When I was about six. My Ex-Dad left here flat broke. Told me to reach the 200th floor. Took me two whole years." Killua explained

Gon: 'Two years? I mean, sure, he was only six... But it took him that long?' Gon thought to himself.

Killua: "There are guys of Hisoka's caliber but only farther up, so dont waste time. Ya got it?" Killua asked.

Gon: "Uh, hey, do you know if anyone here is Y/n's level?" Gon asked.

Killua: "Most likely not. But it has been a long time since I've been here, so I probably forgot." Killua responded.

Announcer: "Number 1973 and 2055. to ring E." The announcer said.

Gon: "2055! That's me! Oh man, I'm getting pretty nervous right about now." Gon said as he took off his backpack.

Killua: "Gon. You made it through the Testing Gate, right?" Killua said, making Gon confused.

Killua: "So, relax." Killua said as Gon ran toward the Arena.

-Cut to the Arena.-

Random: "Check it out! It's just a kid!" Someone shouted.

Random 2: "Hey! Ya better run while you still can, kid!" Another person shouted.

Random 3: "This ain't a game! Punch him and send him flying!" Another person shouted, wanting to get Gon out of the arena quickly.

Referee: "This is a first-floor fight so we will be appraising your Skill levels. You're allowed three minutes to demonstrate what you're capable of." The ref explained.

Referee: "Now then... Begin!" The red said.

Opponent: "I'm real sorry, kid. But I'll make it fast, so you dont have to suffer!" He said as he tried to punch Gon, only for him to dodge.

Gon: "Okay, so just... push hard!" Gon shouted as he palm struck his opponent, sending him flying.

Gon: 'When did I get so strong?' Gon said as he stared at his hand.

Referee: "2055, proceed directly to floor 50." The ref said as he handed Gon a slip of paper.

Killua then had his fight. Which he ended with a single chop to the neck.

Referee: "Wait. This says you've already been to the 200th floor? And those were some powerful moves. All right. Go to the 180th floor-" He then gets cut off by Killua.

Killua: "Nah. I'll start at 50. I want to take it slow." Killua said as he looked at Gon.

Then, he looks over to see another kid who knocked out his opponent in one hit.

Referee: "You're permitted to advance to the 50th floor." The ref said as he handed the kid a slip of paper.

???: "Osu! Thank you!" The kid said.

-Cut to Y/n.-

We currently see you laying down, staring at the That is the prisoner realm. As you were staring, you were suddenly snapped out of it by Kalluto.

Kalluto: "Big brother!" Kalluto shouted as he laid down next to you.

Y/n: "What is it Kal?" You responded to Kalluto.

After you and Kalluto became brothers, you decided to give him a nickname. You also told him he was allowed to give you a nickname, but he prefers to call you big brother instead.

Kalluto: "I know that you need to Master those new abilities and all, but is there any way of leaving this place?" Kalluto asked.

Y/n: "Hm. You know, now that I think about it, I haven't asked dad about a way to leave yet." You responded.

Kalluto: "Really? Im gonna go ask." Kalluto said as he ran toward Satoru.

Satoru is currently snoozing. Just having the time of his life.

Kalluto: "Hey... Hey dad..." Kalluto whispered while poking him, trying to wake him up.

But to no avail, he didn't even budge.

Kalluto: "Dad... Wake up!" Kalluto said a little louder, but still not waking him up.

You then get up and walk toward Kalluto.

Y/n: "Stuff like that won't work Kal. Watch me, and see how it's done." You said as you walked to the Side of Satoru.

Then, you leaped into the air and landed on Satoru, waking him up instantly.

Satoru: "OW! DAMMIT, KID THAT HURT!" Satoru shouted angrily.

Y/n: "And that, my dear brother, is how you do it." You said as you got up and smiled toward Kalluto.

Satoru: "Ow... Ok, im up... What do you want?" Satoru asked.

Kalluto: "Once y/n's training is done how are we meant to leave." Kalluto asked.

Satoru: "Who knows? Maybe we could combine Solid Grey and Hollow Purple to bust our way out of here." Satoru said, not really knowing how to get out.

Y/n: "How come you didn't do that one on your own when you created Solid Grey?" You asked.

Satoru: "You kidding me? Even after all of the time I spent in here, Im still not skilled enough to combine Solid Grey and Hollow purple on my own." Satoru said.

Y/n; "So you plan to have me help you maintain the combination of Purple and Grey long enough so that we can tear our way out of here?" You asked.

Satoru: "Bingo! Now, go sleep. Gonna need your rest." Satoru said as he went back to sleep.

Y/n: "Well, Now we know. You happy with that answer?" You asked Kalluto, as he nodded.

Y/n: "Alright, Later." You said as you walked off and laid down.

Kalluto: 'This is nice. If I would've known that I would end uo with these two, I would've left the Zoldycks a long time ago.' Kalluto thought while smiling.
