* Danbei Makiba, a character Go Nagai had already used in previous mangas: {{Abashiri Ikka}} and ''Anime/CuteyHoney'', is Hikaru's father. He is obsessed with meeting aliens (making him the poster boy for BeCarefulWhatYouWishFor) and spends a lot of his time gazing at the sky with a telescope, hoping for seeing a flying saucer instead of taking care of his ranch. When Kouji arrived at the ranch, he thought it was a visitor from another planet (then again, Kouji WAS flying a built-on-Earth flying saucer and wearing a LatexSpaceSuit, both of which didn't help his case) and tried talking to him in what he would think was an alien language...but it was nothing but gibberish. He is also fiercely protective of his daughter, constantly threatening to blow the brains out of anyone who even thinks about hurting her in any way, shape or form.
