Theme song


  • to be added


  • This is the second summer film to be released in July.
  • This is the first movie to be released in the Reiwa era.[10]
  • As with Build's summer film, this movie is also named after its theme song, with the film's theme song being sung by the featuring artist of the show's theme song.
  • Although this film is a conclusion to the last Heisei Rider TV series Zi-O and is released in the Reiwa Era, its three villainous Riders' names and designs take elements from and represent series that have aired in the Heisei Era, but do not fall under the Heisei series classification:
  • Krim Steinbelt's ancestor living in Sengoku period Japan is a reference to the fact his actor, Chris Peppler, is an actual descendant of Akechi Mitsuhide, a Sengoku period warlord who betrayed and murdered Oda Nobunaga.
    • Coincidentally, Mitsuhide Nira is a character named after Akechi Mitsuhide, who is in fact a corrupt police officer aligned with the Roidmudes who set up Shinnosuke Tomari after he is revealed to be the culprit of his father's murder.
