I swear, this happened to me, this weekend on a tournament... perhaps it is not the reason why such a few girls are playing go (it could be the consequence; who knows), but it certainly might be the reason why a girl would quit playing - or, at least, stop attending tournaments :)
at first I thought of a second panel showing chidori throw that melon she is carrying at the nice oh so funny fellow, but I think this should be enough :)
