"Vampire Knight Guilty" - 13 episodes
The sequel is better but the ending sucks. The build up was filled with dramatic suspense and I wasn't prepared to see the story simply ending just like that. The manga is still ongoing and I'm hoping for the proper finishing touch straight from the original creator herself. Up to the end I still can't decide if I'm Team Zero or Team Kaname. :s The bishies are pretty much fanatic over Kaname until the very end of the anime. But for those who are wishing for a reverse harem, here's a great news. There'll be an otome called "Vampire Knight DS" to be released this January 29. It's a different storyline and you can pair up Yuki with your favorite bishie. Watch the teaser here.
"Hakushaku no Yosei"- 12 episodes
Lydia becomes Edgar's fairy doctor in his quest to become the Earl. This is one sweet anime. I love the opening classic/pop music and the ending credits starting from episode 2. Don't forget the episode ends only after the credits. Only two guys are officially after her, while the other two guys are followers of the Earl. I'll check the light novel and try to see if the other guys will give some clues and if there's a possibility for a second season.
"Shitsuji-sama no Okiniiri" - 5 volumes (ongoing)
Ryou transfer to an elite school serviced by butlers. The other two are loyal butlers of the 'butler'.
