The very first anime/manga fanfictions I wrote are for Get Backers. The anime/manga is included in shounen genre, I think, but many fangirls write yaoi fanfictions for Get Backers. Me? I wrote general stuff for them - I was still an angel back then (er, correction, I'm still an angel even now! ^__^ ) The first two GB stories were published at Animenation forum and the third one was published in Anime Teahouse.
