Original specials of mini-anime by Nii Marco presented after the premiere of the main movies.

Despite having seemingly returned to their normal lives, Kei Kurono, Masaru Katou, and Kei Kishimoto are forced back into the lethal game after Gantz's recent activity. The black sphere continues to summon recently deceased people to fight alien invaders. And having survived the two previous encounters, the trio are more than prepared for the upcoming missions. As they progress through the tournament's stages, the three proceed in their attempt to earn 100 points, which is said to be the only way to leave the parallel dimension for good. However, with the constant onslaught of alien invaders and the threat of imminent death, they must first focus on the task at hand—immediate survival.

In the wake of the destruction of a worldwide non-nuclear war, the city Olympus has become the control center of the world. Run by Bioroids (cloned humans made from only the best DNA), it is defended from terrorists by special military forces. Among these are former LAPD SWAT member Deunan Knute and her multipurpose cyborg partner Briareos. They face a challenge from the Human Liberation Front and its terrorist underbelly the Argonauts. The leader of this group, Al Ceides, supposedly died 20 years ago in an attack on Poseidon, but now his shadow emerges once again. (Source: Aniworlds)
