Joker: Marginal City

In 1937, before World War II begins in earnest. Lieutenant Colonel Yuuki of the Imperial Japanese Army forms the "D Agency," an army intelligence outfit under his command and tutelage. Army General Staff attaches Lieutenant Sakuma to observe the unit's performance. D Agency casts a wide net to find agents beyond Japanese military personnel, and Yuuki establishes D Agency's tenets, which go against IJA doctrine: "Don't kill, don't get killed, don't get captured." With this, Yuuki trains a team of operatives who conduct missions against domestic and foreign powers.

Motorcycle enthusiast Shogo mistakenly comes into possession of a government prototype bike. Pursued by ruthless goverment agents he plans to save himself by exposing the bike to the public on a live TV show hosted by a popular singing star. But, even the lovely Eve has secrets of her own and the government has much more to hide than just a transforming military motorcycle. As Shogo begins to unravel the mystery of the bike, he discovers a reality-shattering secret about the city and the world he thought he knew.
