Gantz Collection

After trying to rescue a man on the subway tracks, two teens wake up in a room dominated by a mysterious black sphere that sends them to hunt down and kill aliens hiding on Earth.

Kato's (Ken'ichi Matsuyama) death changes Kurono's (Kazunari Ninomiya) view of life completely. He decides to keep fighting until he earns 100 points so that he can bring back Kato. GANTZ calls back several other unwilling participants that were allowed to leave after scoring 100 points. Before Kurono succeeds in resurrecting Kato, he unexpectedly comes back. GANTZ and the fighters take on another enemy worse than ever before. To make matters worse, GANTZ starts acting up. GANTZ chooses the next target... this time it's not an alien but a human girl. Each unwilling participant in GANTZ's twisted game has a different motive for fighting, whether to protect a loved one or to do what they think is right.

This film is an alternate perspective version of the first Gantz film from an investigative journalists point of view and depicts the secrets of Kurono and Kato's childhood, and also other character's secrets. Delving deep into the mystery, the film offers another piece towards solving the complex puzzle that is the world of Gantz.

After being brutally murdered in a subway station, a teen boy awakens to find himself resurrected by a strange computer named Gantz, and forced to fight a large force of invading aliens in Osaka.
