Gen-An's character was inspired by Johnny Depp's titular character from the Tim Burton film Edward Siccorhands. When asked why Gen-An became a green, hunchbacked character instead of more resembling Depp, series creator Yasushi Adachi replied: "I think you’ll agree with me on this, but Genan is more handsome than Johnny Depp. [Laughs]"
