Mimay, sometimes spelled Miime, remains the sole survivor of her unnamed alien species from the planet Jura near the star Antares. Her people perished when the plant-based Mazon invaded and ravaged their homeworld. Left alone in space, she was rescued by Captain Harlock. From that moment, she devoted herself utterly to him, joining his crew aboard the starship Arcadia and pledging unwavering loyalty in both body and soul. In the "Harlock Saga" continuity, her origins differ: she is a Nibelungen from the planet Valhalla and Alberich's younger sister. Witnessing her brother's malevolence, she defects and aligns with Harlock to thwart his schemes. Physically, Mimay embodies Leiji Matsumoto's signature willowy design: pale skin, pupil-less yellow eyes, and no visible mouth. Her hair color varies but is frequently purple, complementing her typical long, loose-fitting lavender dress. Her personality radiates calmness, wisdom, and deep empathy. She maintains stable, respectful bonds with all Arcadia crew members, serving as their moral compass and counselor. Her absolute loyalty to Harlock stems from gratitude for her rescue and shared ideals. She follows him without hesitation, even into grave danger, demonstrating quiet courage. Mimay possesses minor psychic abilities, mainly telepathy, which she uses sparingly and only when critical. In some series, these powers extend to prophetic visions. Biologically unique, she subsists entirely on alcohol as her primary nutrient source, though excessive consumption can induce drunkenness and sleep. She often shares drinks with Harlock and Dr. Zero, reinforcing her role as confidante. Across media, she consistently acts as Harlock's closest advisor and emotional anchor. In "Endless Odyssey," her telepathy proves pivotal in reuniting the scattered Arcadia crew. In "Harlock Saga," her knowledge of Nibelungen lore and defiance against Alberich directly aid Harlock's quest. She symbolizes resilience amid loss, her presence underscoring themes of found family and interspecies camaraderie aboard the Arcadia. Her species' tragic extinction and her devotion to Harlock's cause form the enduring core of her identity.
