Hokuto no Ken: Raoh Gaiden Junai-hen

In the wasteland left by nuclear war, Raoh marches toward conquest as the self-proclaimed King of Fist, supported by his childhood companions Souga and Reina. His advance brings him close to the empire of Souther, the Holy Emperor and master of Nanto Ho-Oh Ken, whose mysterious body makes even Raoh wary of challenging him directly.

Meanwhile, Kenshiro confronts Souther and discovers that his Hokuto techniques cannot strike the emperor's vital points as expected. After Kenshiro is defeated and Shu is captured, Reina searches for Toki in hope of finding a way through the crisis. The clash with Souther exposes not only the limits of strength, but the forms of love and devotion that drive Raoh, Kenshiro, and those who stand beside them.
