Yeah, but i was thinking how during the whole show, absolutely no one noticed it. Not even Wing and Biscuit, who used gyo in front of Killua.

<p>Hisoka uses In to conceal his bungee gum which is visible with gyo, so I figured Illumi must have also masked his needle with In. I think anyone could see with gyo that Killua has a different aura on him, even a little. Because that is certainly a nen needle. </p>

<p>So is Killua's luck just so bad that nobody ever noticed it and said something?</p>

Was it not possible to see Illumi's needle with gyo?
