Several people from the original Shinobi return. Kaneko was also the writer for Rider Time Shinobi 1-3. Hatsumura Kenya who narrates is also the voice of the Shinobi Driver.
Amakusa Shirou Tokisada is based on a real life person. His alternate form, Geronimo, was one of the real Amakusa's western names. He was later known as Francisco.
Fuku, a celeb well known for his love of Kamen Rider, plays a parody of himself being a fan of Kamen Rider Shinobi. However, in the background he has a poster for an adventure show with some parody of Rider show catchphrases. "Now, I'm the trump card!" (a mashup of either W or Wizard and Blade) and "Understand everything, connect everything", a parody of Decade's show motto.
As the camera pulls out, it shows that Fuku's show airs at the same time slot as Kamen Rider, and that his show is much more popular. At 32.5% viewership, it beats the original Kamen Rider's top viewership rating of 30.1% for Kamen Rider 41.
