I only just finished watching Princess Tutu, and I gotta say, it's one of the best animes I've ever seen. The plot is really complex and unique, characters are interesting, animation is lovely, and the soundtrack is all different songs from famous ballets...it's quite a ride!
Yaoi-wise, I'm seriously in love with Fakir/Mytho. It's so cute and sweet.

You can't deny that kind of cute.
