Now you know one of the few things about anime that's irksome. All the androgyny. Fangirls into bishonen who are so bishonen they're borderline lesbians.
But I say it looks like a girl. It's more than just the hips. The cheekbones are higher than a male's and the nose and mouth are closer together as well. Also, the way the neck is attached to the head is a giveaway too.
