Gantz

Gantz (ガンツ Gantsu^?) is a Japanese manga and anime series written and illustrated by Hiroya Oku. Gantz tells the story of Kei Kurono and his friend Masaru Kato who die in a train accident and become part of a semi-posthumous "game" in which they and several other recently deceased people are forced to hunt down and kill aliens armed with a handful of futuristic items of equipment and weaponry.

The Gantz anime, directed by Ichiro Itano and animated by Gonzo, ran for 13 episodes and had a direct sequel called Gantz: Second Stage, which continued the series for another 13 episodes. Both seasons make up the 26 episode series. It was licensed in North America by ADV Films. The anime series is distributed in the United Kingdom by MVM Films, and in Australia and New Zealand by Madman Entertainment. Dark Horse Comics started releasing the manga in English in June 2008. A series of two live-action movies based on the manga are also currently in production and will be released in 2011.^[1]
