Rairaiden

A young, large-breasted ninja girl is captured while attempting to steal a legendary sword from a powerful collector named Asano. Thrown into a dark prison cell, she encounters Raikoumaru, the true owner of the blade, who has also been imprisoned. Despite their initial distrust, they realize that working together is their only chance to escape.

As they plan their breakout, the ninja girl learns that Raikoumaru's sword holds a deep significance, and Asano's collection is far more dangerous than it seems. With limited time and resources, they must navigate the prison's traps and guards, relying on each other's skills. The ninja girl's agility and Raikoumaru's knowledge of the sword's power become crucial as they face Asano's forces.

Their escape attempt leads to a confrontation that tests their resolve, forcing them to decide whether to reclaim the sword or leave it behind. The bond formed in captivity becomes their greatest weapon, but Asano's obsession with the legendary blade may prove to be an insurmountable obstacle.
