Sankarea is another super popular ecchi manga, it's probably the only zombie/ecchi manga series currently. The story originally has a touch of terror and romance, but the extra spices quickly blend in and you just can't get enough of it. Even if you're not a big fan of zombie media and gore, you should definitely give this manga a try.
