Gantz

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, equipment, and weaponry. Both the manga and anime are noted for their heavy violence and sexual content.

The Gantz anime adaptation, directed by Ichiro Itano and animated by Gonzo, the series contains 26 episodes divided into two seasons. It was licensed in North America by ADV Films.

Plot

A pair of high school students, Kei Kurono and Masaru Kato, are hit by a subway train in an attempt to save the life of a drunk homeless man who had fallen onto the tracks. Following their deaths, Kurono and Kato find themselves transported to the interior of an unfurnished Tokyo apartment. The pair soon realize others are present and find that they are not able to leave the apartment. At one end of the room there is a large black sphere known as "Gantz".

After some time in the room, the Gantz sphere opens up, revealing a bald naked man with a breathing mask and wires attached to his head, with three racks protruding from it, that offer various items for them to use. These include the custom fitting black suits Gantz made for each of them, giving them super-human strength, speed, stamina and relative invincibility, a controller which acts as a radar and stealth unit, and three types of weapons.

When the Gantz sphere opens, green text appears on its surface, informing those present that their "lives have ended and now belong to him". A picture and brief information is shown of some of the Gantz' targets; Gantz orders them to go and kill them. All but one target shown thus far have been aliens living on Earth, which take on a wide variety of forms. After a period of time which varies between missions, everyone except Gantz is transported to the location of the mission. Those sent cannot return from the mission until all enemies have been killed, or the time limit has run out. If they survive a successful mission, each individual is awarded points for the aliens they have killed. Once a participant has scored 100 points, a "100 point menu" will appear. The menu offers three options. The first option allows the participant to return to their normal life, not to be summoned by Gantz again. Their memories of Gantz and the missions will be erased. The second option grants the participant an extremely powerful weapon. The third and final option allows the participant to revive someone who has died during a mission from Gantz' memory.
