From the creator of Astro Boy and Blackjack comes an epic sci-fi western on Mars starring Captain Ken and his trusty steed, Arrow. Captain Ken is an enigma. Not a single person alive knows who he is, why he’s on Mars, or why he looks just like Miss Kenn Minakami. His presence sparks a revolution—while the Martians seek to reclaim the lands stolen from them, human townsfolk aim to rid themselves of the corrupt Mayor Deven. Amidst the whirlwind gunfights and horseback chases, Captain Ken must go on his greatest adventure yet to save a woman of great importance in the middle of a Martian revolution.
