Megazone 23 (1985) IMDb
A group of teenagers have carefree lives in what they believe is contemporary Japan. The discovery of an advanced motorcycle, and a government cover-up of its existence, starts a chain of shocking revelations and violence.
Science fiction, action. Direct-to-video feature, supposedly a compilation of material from a TV series that was never produced. Clearly a child of the time of Akira (1982) and a potential seed of The Matrix (1999). This is slightly harder science fiction, but loosely directed. I get the sense that, as in Mobile Police Patlabor: The Movie 2 (1993), part of the power of the film comes from the idea that the calm and wealth of Japan at the time were conceited and based on a false sense of isolation. Good bummer ending.
Shogo and Yui reunite after some months, with the nihilistic motorcycle gang. They have lost the Garland, but continue to track the real Eve.
The resolution of the story arc from the first “episode”, also at feature length. Very different in visual style, mostly because all of Mikimoto Haruhiko’s characters are very ambitiously redesigned by Umetsu Yasuomi. Strongly nihilistic and, ultimately, apocalyptic. Heavy on the punk in cyberpunk.
Arcade games are cool.
Only barely a sequel. Almost completely isolated from the plot of the preceding parts by several centuries and what appears to be a retcon. Part III has two episodes, rather than being a feature-length work like the other entries. More typical cyberpunk stuff. Much less original.
