Genji and his victorious G.P.S. alliance find themselves facing down a new challenge by the students of Hosen Academy, feared by everyone as 'The Army of Killers.' The two schools, in fact, have a history of bad blood between them. And the simmering embers of hatred are about to flare up again, burning away any last remnants of the truce they had so rigorously observed until now.
After the Akizuku clan fall in defeat to rival clan Yamana, Princess Yuki (Nagasawa Masami) and general Rokurota (Hiroshi Abe), take cover in a hidden fortress, along with their clan and gold treasury. Fortuitously stumbling into the hideaways, brash young miner Takezo (Matsumoto Jun) and his bumbling sidekick Shinhachi (Miyagawa Daiuske) hatch a daring plan to help transport the gold out of enemy terrain - in exchange for a share of the stash, of course. With assassins hot in pursuit, Yuki disguises as a male and ventures into the real world with Rukurota and her peasant companions, getting her first taste of danger, toil, and budding romance with the strong-minded and willful Takezo.
