Hmm well I recommend the animes: Code Geass, Black Butler, Ouran High School Host Club, Fruits Basket, Soul Eater, Darker Than Black, Vampire Knight, Trinity Blood, Ghost Hunt, Mirai Nikki, Death Note.
Mangas: Fruits Basket, Mirai Nikki, Black Butler, Vampire Knight, Ouran HSHC, Soul Eater, Death Note etc
If you're into horror/mystery I suggest Higurashi/When They Cry, Elfen Lied, Hellsing, Umineko, Another.
