While we are waiting at an open window I had sensed a presence with my Observation Haki which I keep always active, it helps train it when doing that as well.

He sent a little killing intent over to us, Gon and Killua looked over to where they felt it come from, I also looked over there to play along with Netero, then Gon asked.

[Did you guys feel that as well?]: gon

[[Yeah]]: soren and killua

I notice Netero behind us so I turn around to intercept him.

[Ohoh. So you noticed me huh?]: netero

[Yeah, I had felt your presence since you were behind that corner over there]: soren

[Oh? So if you knew then why didn't you get in a stance to fight with an unknown enemy?]: netero

[Because, there are hardly any worthy people who could beat me, if I count right now.. it would be about 4 or 5, including you]: soren

[Oh, so bold. I came here looking for entertainment, would you 3 like to join me for some fun?]: netero

[Yeah! We-]: gon

[Gon! Shut up, you don't know this guy]: killua

[But he seems nice Killua]: gon

[Not everyone is what they seem Gon]: soren

'I do want to play his game so I will get everyone to participate'

[What kind of fun do you have in mind Old Man]: soren

[Hmm, if you can take the ball away from me within 10 hours you will become Hunters on the spot]: netero

Netero pulled a ball from behind his back and showed it to us.

[I'm in, how about you guys?]: soren

[I'm in as well]: killua

[Me too! If I can get the ball I will be a Hunter faster]: gon

I kind of want to help Killua and Gon win right now and train with them but what about Gon's friends. Leorio and Kurapika I think it was. I think Gon wouldn't like to see his friend not become Hunters.

[Follow me to the training room then, and we will have some fun]: netero

We follow him to the room and it is a padded room it's about 5 meters in diameter.

[Okay, when I say start you will have 10 hours to take this ball, if you do. I will make you Hunters on the spot, if not. You will still take the rest of the exams]: netero

[And START!]: netero

I go first covering my hands in Armament Haki my hands become Black and have a Purplish Red aura around them.

'Hmm, this kid! He can use Nen at his age?'

Netero thought and I guess I caught him off guard because I was fast enough to almost grab the ball. I back off and release the Armament Haki so Gon and Killua wouldn't see it.

[How about you guys try for a bit I need to think of a strategy]: soren

[[Okay!]]: gon and killua

I sat on the wall and observed from afar. As I watch Killua and Gon work together I see Killua get frustrated.

[I quit, He hasn't even used his right hand and left leg. Gon let's go]: killua

[No, I want to stay]: gon

[Gon! You will never get that ball]: killua

[I know]: gon

[Then why? Why keep playing at his game?]: killua

[Because, I want to make him use his right hand]: gon

[...What ever, I'm out of here, Cya later Ren]: killua

Killua had a look of murder on his face. He almost would have tried to kill Netero.

[Will you try again Ren?]: netero

[You can't call me Ren only my closest friend can call me that]: soren

[Ohoho, so will you continue Soren?]: netero

[Yes but, I need a bit more time to observe]: soren

[Okay!]: netero

I watch more as Gon attacks Netero, then Gon pulls his Head buster move, Netero doges with his Right hand. Gon crashes into the wall and then gets back up.

[I did it! I made you use your right hand!]: gon

[Hmm, I guess you did]: netero

Gon passed out and I walked over to Gon and move him to where I was.

[Oh, so will you attack now?]: netero

[Old man, I want to make one thing clear]: soren

[Oh? And what would that be?]: netero

[I didn't want Gon and Killua to witness my power because I didn't want them to see how powerful I really am]: soren

[Oh? So you will use your full strength now?]: netero

[Yes! And one more thing. When I take the ball I still want to take the rest of the Exam, will that be okay?]: soren

[Well if you could take the ball from me then you would qualify as a top rank Hunter in around the top 200's. But if you take it then yes you can still take the rest of the Exam]: netero

[Okay good, I didn't want to leave them 2 to finish alone]: soren

[Then shall we start now?]: netero

[Yup! Get ready Old man you will half to use more power than normal to keep that ball from me]: soren

I start to release all my Nen covering my body, then use Armament Haki to cover both my Hands and Feet.

[Oh, quite strong!]: netero

[Oh, I'm not done yet]: soren

I then use Observation Haki to the max making my aura Spike and change color to a Reddish Purple mist and then I yell.

[REN!]: soren

My aura Spikes again and the look on the Old man's face changes.

[Oh my, what a monster]: netero

[Are you ready old man?]: soren

[...Yes, come at me when ever]: netero
