Gantz - Hiroya Oku

Life is complicated for Kei Kurono, possibly the horniest teen in Tokyo. So far he's had to deal with sleeping next to a sad but excessively cute and endowed girl who asked to be his 'pet'; the fact that he's apparently really a fax copy of himself - the real version having died in the first volume; and falling out of the sky after being dropped by some sort of alien eagle. Hiroya Oku's "Gantz" takes sci-fi and manga to a whole new level. Chock full of action and awkward sexiness, "Gantz" is not to be missed!
