Character Profile: Illumi Zaoldyeck

Irumi is Killua's older brother, he is oldest of the Zaoldyeck children. Irumi took the hunter exam under the alias Gittarackur. His weapon is needles, needles that look like something used in sowing. As Gittarackur, the needles stick out everywhere from his body, but as Irumi they stick out near the chest.

Irumi is also a hunter, and friends with Hisoka. He calls his brother Killua "a person with out any humanity and a dark puppet who is controlled."

Illumi's nen ability is the ability to change his face using nen, so he can look like some one else. He does this in the YorkShin arc so Hisoka can go fight Kuroro. Illumi can also use pins to disguise himself by sticking them in his face to change his face's shape. He seems to prefer using his pins to his nen because his disguise with nen only lasts about an hour.
