Green onions are enough for me. That's what the poor little alien says, but green onions aren't enough for the trigger happy alien hunters who are being controlled by the black ball known as Gantz. After seeing a dog going down on a girl, and the same girl nearly getting raped, you'd think it couldn't get worse right? Wrong. In this episode, we see just how rutheless the "dead" can be when given space age weapons and a mission.
Kurono and Kishimoto decide to head to Kishimoto’s old house to see what the "other Kishimoto is like". What will they discover? Meanwhile, Kato is having trouble at home, with his aunt beating his littler brother, and at school, with bullies picking on his friends. When a senior challenges him to a fight, will he go too far?
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.
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.
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.
