As Ichimatsu battles the demons within his soul, the fight for justice against the Shogunate continues. Lord Kozan's new position has increased his power, and thus, the Anti-Samurai Gun Unit has become even more deadly. They have garnered even bigger and badder weaponry - and their counter-intelligence has moved them dangerously one step ahead of our freedom fighters. And that spells trouble.

With three very important missions on the docket, the Samurai Gun warriors cannot afford to lose their technological advantage. A highly secretive package must be transported through enemy territory, an extremely valuable captive must be rescued from prison, and an entire village must be pulled from the clutches of ruthless killers. It's time for the Samurai Gun!
