Herlock Saga: Nibelung no Yubiwa

Alberich means to bring down the gods of Valhalla, and the stolen Rheingold gives him the power to try. Forged into a ring, the metal turns his revenge into a threat to the entire universe.

His sister Miime warns Harlock of the danger. The captain and his companions set out to recover the ring, fighting for the lives caught in this struggle rather than for the gods who rule over them.
