- What Could Have Been:
- A previous concept had Yuuta depicted as a girl, which would have made him one of the very few female main characters in the Brave Series. His features still carry more of the show's female characters' traits than of the males' of his age. Lampshaded when he disguises as a school girl — with school uniform dress and pigtails - and absolutely looks the deal. To be fair, many children his age are androgynous before puberty hits.
- There were rumors about a sequel or spin-off of the show, partly focusing on the Scotland Yard Brave Police.
