I see a hell of a lot of girls buying anime and manga. A pretty equal mix of guys and girls actually.
Caught someone out in my local CEX the other day (second hand games/DVDs) She had some anime boxsets that they didn't have on their system and so couldn't take, so the guy serving her called me over as we're friends and he knows I like anime, and when he asked me if I wanted them I sort of pointed out that they were Chinese bootleg boxsets. Don't think I made a friend there ^_^
