Romance - Clannad,Clannad After Story, Fruits Basket, Ah! My Goddess.
Action - Soul Eater, Samurai Champloo, Bleach
Fantasy - Fairy Tail, Howl's Moving Castle(movie), Spice and Wolf
Comedy - Hetalia!!!
Horror - Mirai Nikki, Hell Girl, Higurashi

Well since you like Kaichou Wa Maid Sama (The Maid Sama manga is a favorite of mine)
I recommend:
- Kamisama Kiss (I prefer manga, but like the anime)
-Ao Haru Ride- I becoming an anime in the summer
-Kyoukai no Kanata (A mix of urban fantasy, action, and romance.)
-Steins:Gate- (Confusing at first but its basically the butterfly effect and time machines)

For horror-
-Higurashi (Watch both seasons. The first season is Higurashi no naku koro ni. Season 2 Higurashi no naku koro ni kai. It is confusing if you don't watch both.
-Another- Straight up horror

If you like Inuyasha, you should enjoy Ranma 1/2 & Ruroni Kenshin. 15 years ago, both were required watching for otaku. Ranma does have partial nudity though....A lot of it.

You should also enjoy Sabor Marionet J, Sorcerer Hunters, Fushigi Yuugi, Legend of Himiko, Gokudo-Kun Manyuki, Slayers, Master of Mosquiton 99 (has to have the 99 in the title), Majin Tentei Nougami Neuro, Excel Saga, Gintama, Juubei-Chan, & Houshin Engi.

If you're not homophobic there's also Kyou Kara Maou, & 90% of the "heavily implied romance" in Hunter x Hunter 2011 is gay, as well as 60% in Gensoumaden Saiyuki, & 50% in GetBackers, 40% in Yu yu Hakusho, & 30% in Nightwalker.

All of these series have ALL of the elements; action, some degree of horror, comedy, full or implied romance, & fantasy.

Mangas you may like: Dragon Half & Petshop of Horrors.

The animes for GetBackers 7 Majin Tantei Nougami Neuro only cover half of the manga.

If you have a strong stomach & can tollerate the sort of nudity meant to disgust rather than arouse, there's also Apocalypse Zero, which also has all of these elements.
