In the sequel to Shirows’ classic anime, Al, Leona, and their trusty steed Bonaparte continue to fight crime in New Port City alongside the rest of the Tank Police. A new threat emerges in the form of a series of terrorist attacks that employ cutting‑edge weapons technology. Although the Tank Police are outnumbered and outgunned, Al and Leona set out to discover who or what is behind these assaults. Their investigations lead to massive explosions and high‑speed chases, during which Leona often causes more damage than the criminals she pursues.
