Gantz (2010) Timeline Explained – Every Event in Order

Each Gantz participant earns points by defeating alien targets during their assigned missions, with points awarded based on the difficulty and number of kills. Reaching 100 points unlocks a crucial menu of three options: return to your previous life with all memories of Gantz erased, acquire a powerful weapon for future missions, or resurrect a fallen comrade. This mechanic drives almost every strategic decision the characters make throughout the film.

During the climactic moment of their third mission in Gantz, Kato deliberately threw himself into danger to take out the last remaining alien target while Kurono lay severely injured nearby. Kato absorbed the enemy's final attack so that Kurono could escape alive, even though he knew it would cost him his life. This selfless act becomes the emotional turning point of the entire story and reshapes Kurono's character forever.

Foreshadowing: Kato's willingness to die while saving the homeless man at the subway tracks foreshadows his later willingness to sacrifice himself for Kurono during the third mission.

According to the revelation during the final invasion arc in Gantz, the mysterious black sphere is not a human invention but a gift bestowed on Earth by a superior alien species. These benefactors armed humanity with Gantz in order to give them a fighting chance against hostile alien invaders who sought humanity's extinction. The actual motivations of these superior aliens remain ambiguous, leaving one of the film's biggest mysteries unresolved.

Kurono and Kato joined the Gantz game because they both died in a heroic but fatal attempt to rescue a drunken homeless man who had fallen onto subway tracks. After the train struck them, Gantz resurrected them in a Tokyo apartment alongside other deceased participants and forced them to hunt alien threats. Their selfless act of saving a stranger is what pulled them into the death-game cycle in the first place.

Before Kato's sacrifice, Kurono was largely self-interested and focused on his own survival during the brutal Gantz missions. After watching Kato give his life to save him, Kurono undergoes a dramatic transformation, adopting a heroic mentality and resolving to use his accumulated points to revive his fallen comrades. The change turns Kurono from a reluctant player into a determined leader willing to risk everything for his team in future battles.

The catastrophe countdown was a hidden display that the veteran Gantz player Joichiro Nishi uncovered on the surface of the black sphere itself. It revealed an impending global extinction-level event tied to the alien forces already operating on Earth, giving Kurono's team only about one week to prepare. This discovery directly foreshadows the massive alien invasion that arrives at the climax of Gantz.

Eeva, the alien commander leading the invasion of Earth in Gantz, singled out Kurono as Earth's champion because he had become the most accomplished and recognizable Gantz fighter of his generation. By demanding Kurono step forward personally, Eeva framed the conflict as a one-on-one duel between Earth's strongest warrior and alien leadership, with the fate of humanity hanging on the outcome. Kurono accepts the challenge knowing that Earth depends on him.

Kurono revived Kato by carefully accumulating enough points across multiple Gantz missions to reach the 100-point threshold. Once he hit that benchmark, Kurono chose the 'resurrect a fallen comrade' option from the Gantz reward menu, which brought Kato back to life. This resurrection mechanic is the same one that allows any successful Gantz participant to bring back allies lost in earlier battles.

As the alien threats escalated and the missions grew more destructive, the boundaries between the Gantz battlefields and the real world began to break down. This evolution made the hunts observable by regular humans, dramatically raising the stakes and removing the secrecy that had previously protected the participants. The change signals that the alien war is no longer a hidden phenomenon but a public crisis threatening all of humanity.

Facing an extinction-level alien invasion, Kurono and his allies deployed Gantz's advanced suits, energy weapons, and coordinated tactics to defend Tokyo against overwhelming odds. The battle culminated when Kurono personally defeated the alien commander Eeva in direct combat, with Kato providing crucial support during the duel. Their victory saved Earth and returned the pair as celebrated heroes who had sacrificed everything for humanity.

During a critical late-stage mission in Gantz, Kurono's Tokyo team was forced into a joint operation with a rival Gantz team from Osaka that operated independently with its own roster and scoring system. Their cooperation was tense because both groups wanted to maximize their own point totals and prove their superiority against increasingly powerful alien targets. The collaboration ultimately proved essential in tackling enemies that neither team could defeat individually.

Nurarihyon was a boss-level alien assigned during one of the most difficult Gantz missions, far stronger and more durable than standard alien enemies. Defeating Nurarihyon required the combined efforts of both Kurono and Kato, with Kato ultimately landing the killing blow while sustaining grave injuries in the process. The battle demonstrated how the escalating difficulty curve of Gantz missions was pushing even top-tier fighters to their absolute limits.

During a later Gantz mission, Kurono's team encountered a powerful nest of vampires whose speed, strength, and regenerative abilities made them far more dangerous than any previous alien targets. The battle cost Kurono his life when the vampires overwhelmed him, though his teammates used the points earned from the mission to eventually revive him. This encounter marked a clear escalation in the difficulty and deadliness of the participants' hunts.
