Megazone 23 Part II: Himitsu Kudasai

The events take place in a post-apocalyptic future, where Tokyo only exists as a simulated reality. The story follows Shogo Yahagi, a delinquent motorcyclist whose possession of a government prototype bike leads him to discover the truth about the city.
This is a direct-to-video follow-up to the movies Megazone and Megazone II.
