Trivia / Kamen Rider Spirits

• What Could Have Been:
  • On his blog, the author said that he was denied permission to use Black and RX in the story, but did a few sketches of Kotaro for fun.
  • He also did a sketch of Tsukasa Kadoya as a favor to Masahiro Inoue. Who knows...
  • Kodansha was considering to release the manga outside of Japan, but decided against it due to the mangakas having an inconsistent schedule to release the chapters in Japan for starters. And when it was still serialized, Kodansha preferred to translate/market titles that were already done in Japan.
