A/N: Gon, Killua, Karuto... These kids just get more dangerous every time we see them, don't they? Time-frame set near the end of GI Final, the OVA series.
Mysterious Intentions
Skipping from tree to tree, one of the younger Zaoldycks pursues his targets adeptly and silently. They have not sensed him, but remain wary of their surroundings nevertheless. Even at the unripe age of nine, Karuto already has a perfect Zetsu. He guesses at their destination, a rocky field in the northern parts of Greed Island, where they are to continue solidifying their training under the command of one Bisuke.
This person, Bisuke, is most certainly not what she seems. Hypothesizing from their lack of fear for her, brother and that person Gon do not know that she is one of the endangered tribes of giants. He is impressed by the way that her nen is completely compressed into her faux body, an illusion to make herself seem inconspicuous. She doesn't seem to have noticed him, but he isn't sure if she would react anyhow, as there is no murderous intent in his nen.
Though Karuto feels that brother Killua is losing his edge by being around Gon, it doesn't matter to him. Killua may as well have been exiled from the Zaoldyck family. Pity, too - he has so much disgusting talent that could have been used for better purposes than the ones this Gon can think up.
Even though Karuto is much more powerful at this point, having been conveniently and efficiently tutored in the art of nen by his mother Kikyou, he does not thwart the possibility that Killua may still surpass him - with his sickening talent and all. He's glad Killua's exiled. The attention was all on him, before. Now, Karuto is actually given missions, and mother wouldn't shriek all the time anymore.
Karuto has been recruited as the newest member of the Spiders. This happened right after Hisoka had Illumi disguise himself as the clown, so that he could proceed to try and fight the leader of the Spiders, Kuroro Lucifer. The members of the Spider were good enough to discover him, despite his masking techniques. They were intrigued by his young age and skill, then captured him to have him be interviewed by their leader. Kuroro liked him very much, and he was immediately recruited; two of the obvious benefits were his skill and obedience, not having known any other way within the world of the Zaoldycks. Not having an urgent mission at the moment, Kuroro had Machi order him to spy on these two targets on the basis that they should be prevented from going to help the chain assassin, once the Jyonen user has released Kurapika's nen from the Spider's leader.
He shakes himself out of his reverie. He should pay more attention, after all. Just in time as well, for his targets stopped three hundred meters in front of him, having reached their destination. They are practicing their special abilities... This should be useful.
About two thousand feet into the air, neither Bisuke's party nor Karuto can sense Netero and Ging watching bemusedly.
Ending Notes: Ah, I ended up continuing it after all. Though I'm not sure what I have in mind yet, maybe it'll further develop. I can never cease being fascinated by these characters. Chapter length will be inconsistent.
