Baba Lamunade is trailed home by two odd peddler girls who hand him a CD-ROM game. Once he defeats "The Legend of Lamuness," the girls emerge from his computer and transport him to DokiDoki Space. He is the third descendant of the hero Lamuness, tasked with stopping Don Genosai from resurrecting the great evil Abraham. Alongside PQ, his advisor robot, and Parfait and Cacao, he must pilot the Kaizer Fire mecha. However, a second pilot is required, and Da Cider is selected for the role.
