I don't watch anime that often, but I read alot of manga specially shoujo(romance) manga <3
My favorite anime and manga is Bishoujo Senshi Sailor Moon all the way, it has a great story though you can't really see it by only watching the anime.
I also like Shamanic Princess, Princess Tutu, Rockin' Heaven, AAA, NANA, Bokutachi Shitte Shimatta, Taranta Ranta, Princess Ai, Lovely Complex, Saboten no Himitsu, Chocolate Cosmos and alot more ~
but Sailor Moon is Sailor Moon <3 *addicted*
