Well, I only know one Anime series that I've enjoyed watching sense 2007 and to me, this mostra is one of the best ones on my account. "Cardcaptor Sakura". =) It's a really great show, a mostra filled with mystery and adventures, and the characters in this series just adore me too much.
Try the Anime "Black Cat" Its not very popolare but seriously... when I watched it I loved it so much! And it's not like most animes... where it takes a long time to get good... it's already pwnage at episode 1! xD every episode is a "Must Watch". (Also if your a girl te gonna like it a lot più xD)
