The masters of the Nanto Seiken school are known as the Nanto Rokuseiken-the Six Holy Fists of the South Star. Of the six, the most powerful is the Holy Emperor Souther. But Shu, another warrior of Nanto Seiken, dares to resist Souther's tyranny. Shu once saved Kenshiro's life and they will team up once again. Kenshiro now faces Souther, but is unaware of Souther's secret-a secret so powerful even Raoh won't challenge Souther's reign… For older teen audiences.
