 * An old man who owns a repair shop that Bocca worked at. Kurofune comes to him to have his aibar machine, Jaguar Sun, repaired. When the authorities arrive after Kurofune fights Hor, Saburou flees and joins the armed theater group, Chentaruo (this is not known until later in the series in episode 8–10). When Bocca meets Saburou again, it is revealed Saburou was a scientist who helped in the development of Aibar Machines and the Metronome, the space fortress that gives the Aibar Machines the ability to fly, and was supposed to destroy all monsters.
