is a 2004 Japanese tokusatsu superhero film adaptation of the anime series of the same name. It was written and directed by Kazuaki Kiriya. It is one of only a few films (Sky Captain and the World of Tomorrow, Immortal (both 2004) and Sin City (2005), among others) to be shot entirely on a "digital backlot". Plot A fifty-year war between the Eastern Federation and Europa ends, with the Federation taking control of the continent of Eurasia. A resistance movement rises in Zone 7 and the Federation mobilizes its military. However, the war and heavy industry have exhausted the Federation and polluted the environment. Dr. Azuma presents his discovery of Neo Cells, human cells that, in theory, can be converted to regenerate human tissue. The Neo Cells are only found in the genome of "a primitive ethnic group." He states that he can develop the Neo Cells for human use, but is quickly denounced. But Kaoru Naito, from Nikko Hairal Inc., offers Dr. Azuma sponsorship. Azuma is persuaded when Naito insinuates that accepting will also help Dr. Azuma cure his wife, Midori. A photo shoot at the Azuma Residence follows, commemorating Tetsuya's (Azuma's son) engagement to his girlfriend, Luna. They argue about Tetsuya joining the military. One year later, Tetsuya is deployed to Eurasia Zone 7. He kills civilians, and is killed by a booby trap. Azuma invites Luna's father, Dr. Kozuki, to his lab. They are rivals, since Azuma's cell research makes Kozuki's armor research redundant. However, although organs have been grown from the Neo Cells, they are not usable. Meanwhile, Midori, now almost blind, is visited by Tetsuya's ghost. Shortly after she is told of his death. His body is sent to Azuma's lab. Tetsuya's ghost sees the body. A lightning bolt strikes the facility and stimulates the Neo Cells, causing the limbs and organs to restructure into humans. Naito calls for the military to kill them. But a few escape and encounter Midori in her car, which they hijack. Azuma carries Tetsuya's body into his lab. Tetsuya is resurrected, but his condition is unstable, and he is brought to Kozuki's residence. Kozuki puts him in prototype battle armor. The Neo humans travel to Zone 7, sheltering in a derelict castle, where they discover a robot army. Calling themselves "Neo-Sapiens," they vow revenge and reactivate the robots to wage war upon humanity. Kozuki's residence is attacked and Tetsuya
