The Harlock Saga manga, like many of Leiji Matsumoto's works, remains unfinished. Eight volumes were published, with the last two of a planned three available online in English. The first series, Harlock Saga: The Rheingold, was the basis for the Harlock Saga anime OVA. Harlock Saga: Valkyrie is the first of a two-part story dealing largely with the events surrounding the epic voyage and subsequent death of Great Harlock, Captain Harlock's father, in 2964 AD. The story begins immediately after the events depicted in Harlock Saga: The Rheingold. Wotan, lord of the gods of Valhalla, is furious over Captain Harlock's earlier appearance in Valhalla and his insolence toward himself as lord of the gods. Wotan does not care that Harlock has just gotten through saving Valhalla ; he wishes the whole affair had never happened. To that end he orders his daughter Brunhilde and her cohorts, the legendary Valkyries, on a journey back through time with orders to kill Harlock while he is still a youth. In order to accomplish her mission Brunhilde must cross swords with Great Harlock, the father of the boy she has been sent back in time to kill. The both of them must also deal with the Metanoids, who have designs of their own for the universe that do not take into account the gods of Valhalla. Caught up in this storm of events are four singular young people. First is young Harlock, a teenager who has a great destiny ahead of him but must first live long enough to achieve it. Second is young Tochiro Oyama, young Harlock's best friend and the spitting image of his famous father Dr. Oyama in looks, personality, and intelligence. Third is young Emeraldas, who along with her younger sister Maetel have chanced upon an ancient starship of great power on the planet Metabloody that awaits "... its rightful master." Fourth is young Maetel herself, mysterious even as a child, who seems strangely attracted to young Harlock and correctly senses that the destines of all four of them are bound together by the strands of time upon the eternal Sea of Stars. Harlock Saga: Siegfried is the second of a two-part story dealing with the adventures of Great Harlock. It is also set in the year 2964 AD and covers the events leading up to the death of Great Harlock. The Metanoids are planning to conquer the known universe and have built a fleet of sophisticated warships, the likes of which have never been seen before. All that stands between them and their goal is an unlikely alliance of mortal and immortal: Great Harlock, the legendary space pirate, who sails the Sea of Stars in the second incarnation of his space battleship Death Shadow; and Brunhilde the Valkyrie, shieldmaiden of Valhalla, who has defied her father's orders to kill Great Harlock's son and joined forces with him under the flag of freedom, the skull-and-crossbones of old. Witnessing this great event unfold are Meeme the Nibelung sorceress and four youths who as adults are destined to shape the future of the universe. The manner in which Great Harlock and Brunhilde face the impending threat of the Metanoids, one that will certainly result in both of their deaths, will make a lasting impression on the young lives who must deal with their willing sacrifice. Harlock Saga: Götterdämmerung picks up the story almost a decade after the death of Great Harlock. Meeme, now serving Captain Harlock aboard the mighty space battleship Arcadia, has just finished telling him the full story behind the death of his father. Now that he understands the extent of Wotan's involvement in the affair Captain Harlock is aroused to wrath. Together with his ally Emeraldas he dares to defy Wotan once again and challenge Valhalla's rule over the universe. His actions have been foreseen by Erda the soothsayer, who had earlier predicted that Wotan's attempt to change Harlock's past would result in the Twilight of the Gods and the end of Valhalla. Now that prophecy is coming true, and even as Captain Harlock finishes resolving the legacy of his late father, cosmic forces array themselves for a final showdown at the center of the universe. For some, it will almost certainly mean the end of all things; for others, perhaps, a beginning.
Overview of the anime
Legend tells of the Rheingold, an all-powerful metal used by the gods of Valhalla during the forging of the universe. Legend says that he who wields the Rheingold wields ultimate power over all things; yea, even over the gods themselves. The Nibelheim, former servants of Valhalla who were cast down aeons ago for daring to defy the gods, are once again fomenting a rebellion. Their leader Alberich is on a ruthless quest for the Rheingold and will let nothing stand in the way of his desire to utterly crush Wotan and the gods of Valhalla. Fearing the implications of his actions, his sister Meeme, currently in the service of the space pirate Captain Harlock, warns her friend about Alberich's plans. Together with fellow space pirate Emeraldas, his best friend Tochiro Oyama, and Maetel the eternal traveler, Captain Harlock sets out to thwart Alberich's designs and save the universe... not for the gods, but for all the living beings it contains.
