This Hisoka is one of the craziest character that Togashi created (or you can simply call him a freak)... But many people like him(me too). He seems has a hot for Kuroro (you may take it as Hisoka got excited of Kuroro's power, and looking forward to have a battle with him ONLY, but I think the way he GOT EXCITED to Kuroro was just ... Check the comic if you don't know what I meant), on the other hand he was trying to date Machi, apparently is a pedophile as he "like" Gon a lot, ambiguous to Kurapika and Illumi... He can just do anything! whoops what a philanthropist....

Usually, when I check the Japanese fan arts ... the fans like him as a pairing with Illumi, or kidnap Kuroro for x*&$*^#() ...
