Goreinu

Goreinu (ゴレイヌ, Goreinu) is a Hunter hired by Battera to complete Greed Island. At first, he is wary of joining forces with children, and only grows more apprehensive with the introduction of a naked Hisoka to the mix, but he sticks it out, later calling Killua a friend and saying that he would give them the Angel's Breath card for free if it was used to heal Killua rather than Genthru, the bomber. When Killua objects that his crimes are debatably worse than Genthru's, Goreinu admits that his actions are based on feelings rather than logic.
