Tao, found within the Outer Rim Territories, was a planet of continental size, known for its abundant natural beauty and long-standing traditions. Despite possessing substantial resources, it faced challenges in achieving modernization, ultimately leading it to accept occupation by the Galactic Empire during the Imperial Era in return for industrial progress. The planet's pristine ecosystems were negatively affected by the industrial activities of the Empire, and the people of Tao grew increasingly discontented with Imperial rule. Notably, numerous Lepi, who were not originally from Tao, were subjected to enslavement by the Empire during this time. Furthermore, the Empire established compulsory labor camps on the planet.
Yasaburō, the Boss leading a significant clan, made the decision to retaliate in response to the Empire's oppressive actions. Conversely, his own daughter, Ochō, chose to align herself with the Empire.
