I recommend:

-Ao Haru Ride- I becoming an 日本动漫 in the summer
-Kyoukai no Kanata (A mix of urban fantasy, action, and romance.)
-Steins:Gate- (Confusing at first but its basically the 蝴蝶 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 你 don't watch both.
-Another- Straight up horror

There are a lot of good romantic comedies C:

If 你 like Inuyasha, 你 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.

你 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 或者 implied romance, & fantasy.

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

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

If 你 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.
