Synopsis
Lipumira is searching for the last survivor of the Nomad Star tribe, a man known as Mapman, and tracks him down in Tokyo. Mapman, whose real name is Gen Tokishima, possesses the means to obtain a fragment of the starmap that is hidden somewhere on Earth. Once they retrieve this piece, Gen must choose between joining Lipumira on her perilous quest to locate the remaining parts of the starmap or remaining on Earth. Before he can decide, his girlfriend arrives at the spaceship and insists on being included in the expedition. However, as Gen learns more about the starmap, he discovers that Lipumira's own sisters have concocted plots to sabotage her, willing to go to any lengths to keep her from achieving her goal.
