i liked it

No wonder Illumi and Hisoka get so along well, they both like watching "interesting" things ^o^

Killua isn't his younger brother though, Kalluto is. Then there is an another one (who only made a cameo in both anime and manga) then Killua (who is the third son).

interesting... i'll stay tuned.

haha never thought kuroro and Illumi were friends. In the last bit where he thought Killua and his friends were stupid to take on the Genei Ryodan, i've always wondered what Illumi would've been thinking when he was disguised as Hisoka and saw his brother with Gon all tied up at the base...would he have tried to save him?
neways good job :)

Illumi interested in something. Now that's a scary thought...
