Gantz

Gantz is a science fiction anime that I haven't seen yet, although I have been reading the manga and the original concept of the story and engaging visuals have made me very eager to get my hands on this title. The anime itself has two seasons of 13 episodes each and there have been two live action movies made in Japan. The two main characters Kei Kurono and Masaru Kato are hit by train in the attempt to save a elderly drunk from being killed. After death they find themselves waking up in an apartment room with a bunch of strangers and they are unable to leave. In the middle of the room is a black sphere called the gantz sphere, the gantz sphere opens up and it is revealed that their natural life has ended and they have been employed to work as assassins killing aliens that reside on Earth. I can't really recomend this series from personal thoughts, but I've heard positive reviews and now I pass the reviews on to you. Also I'd just like to note that this is the first anime on here that has an R+ rating, just incase you weren't looking for something so mature. Here is the opening song for Gantz.
