The main series right now are Clannad, Ef~tale of memories (I have just one last ep. to watch), Prism Ark, Minami-ke, Dragonaut, Night Wizard, Ghost Hound, Shana season 2, and Da Capo II. I'm behind on most of these... >.>; And I also have a couple shows from previous seasons I need to finish eventually.
I recently got a hold of the first episodes of Rosario + Vampire, H2O ~footprints in the sand~, and Ayakashi. So I'll also be watching those soon.
