Kei Yuki

Serving as the Arcadia’s skilled chief navigator and science officer, this blonde-haired crew member was rescued by Captain Harlock after an altercation with a military officer. Though she initially appeared to harbor romantic feelings for Tadashi Daiba, their bond eventually transitioned into a platonic friendship. As one of the ship's youngest members, her role is vital to the crew's success, though some later interpretations suggest a deeper, romantic connection between her and Harlock himself.
