Ouran High School Host Club :)

Of course there are, such as Karneval.
Personally, I always hated all other anime except for Naruto. I really think its the best one out there; however there are many other animes that some people really like. Try browsing the site below.
Karin , Kanokon , Sekirei , Love Hina and Maburaho .
sailormoon
Agon Kongo ,
There's Ghost Hunt, and Vampire Knight.
The Cat Returns and Cat Soup .
any there isn't exactly a genre
wolf's rain and Wolf God
I dont think there will be any after that. But i would like to hope for more since this is one of my favorite animes.
