Bao Luzen is an older male member of a spaceship crew surviving the post-apocalyptic wasteland of planet Aqualoid. He habitually smokes and displays a noted appreciation for attractive women, embodying archetypal lecherous old man traits. His role is to join protagonist Nam, Rasa, and her creature Monga in combat against the Inorganics—a destructive inorganic lifeform posing a deadly threat to the universe. Their critical mission focuses on wielding a crystallized light-energy sword to activate a planetary rebirth called "Birth." Bao Luzen operates solely within this collective effort; no individualized character development or personal backstory is provided within the OVA's narrative.
