Sei Juushi Bismarck is the story of four space explorers stationed on Ganymede, a moon of Jupiter. Their goal is to protect our solar system from the Deathcula imperium.Although not as popular as its (arguably Macrekred) version Saber Rider and the Star Sheriffs, it is more sophisticated, and does have action figure toys in its own country.
