User blog comment:Martialmaniac/Enough with Alluka!/@comment-10528819-20150220201831

I don't mind the page saying that Alluka is a boy, but there's still some arguments that make possible that he's a girl, Killua refered to it as her and since his mother is blind and he's the closest to it I take hus word as more reliable than the other ones. Besides that I always thought (this is clompletly unproved and only suposition) that Alluka was a boy and "Nanika" a girl
