The Last Princess (2008)

After the Akizuku clan fall in defeat to rival clan Yamana, Princess Yuki and General Rokurota take cover in a hidden fortress, along with their clan and gold treasury. Fortuitously stumbling into the hideaways, brash young miner Takezo and his bumbling sidekick Shinhachi 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.
