So many people with Atro's gender. Appearances count for NOTHING, in the Anime, Japanese culture. Andrygonous characters exist all over and Atro is one of them. It's very hard to tell his gender as it flipped in Global to a guy instead of a girl (I think, don't quote me.) It all depends on how you see him/her. Personally, I see him as a guy (with a secret twin sister XD)
