Maps follows a normal Earth boy named Gen. He and his girlfriend Hoshimi meet Lipmira, a scantily-clad blonde woman from outer space, who tells Gen that he is the "mapman," meaning the map to a great treasure is coded in his genes. Gen and Hoshimi leave Earth with Lipmira to find the treasure, a quest shared by evil space people whom they are often compelled to fight against. Notable aspects of the series are the spaceships (which look like giant silver angelic women, often described as "hood ornaments") and the robot women that control them, or more precisely embody them for dealings with regular-sized life forms (Lipmira is one of these robot embodiments). Each ship and its pilot have a distinct character, from playful to evil.

Maps was serialized in the Gakken magazine Monthly Comic Nora from 1985 to 1994. The series was adapted into two anime original video animations (OVAs): the 1987 original, fully titled Maps: Densetsu no Samayoeru Seijintachi (マップス 伝説のさまよえる星人たち, lit. "Maps: Legendary Space Wanderers") in Japan, and the 1994 remake, simply titled Maps.
