"According to this DVD, it is said that the ghosts of a sister and brother disappeared in this school while playing here. They are still wandering around to find a playing partner, even to this day. And there is one man who awakens in this school tonight. His name is Geiz Myokoin. He has a hidden secret that he won't tell anyone: And that secret is--Oops. I can't get cursed from here on out. Now then, please watch what happens next."

  • As a Hyper Battle DVD featuring horror/thriller themes, some elements of this special are taken from Japanese horror films or famous animation series.
  • The outfit that Geiz is wearing in this special is the same exact outfit that he wore during the Ex-Aid arc.
  • This is officially considered the last Heisei Hyper Battle DVD Special for the Heisei era. However, the last one to release within the actual Heisei Era was Kamen Rider Prime Rogue, while this one released in the Reiwa era.
  • The title being romanized as BibillGeiz may be a reference to billionaire and Microsoft founder Bill Gates.
    • A similar joke connecting Geiz's name to Bill Gates was made in Kamen Rider Zi-O: Supplementary Plan episode, Mystery of Naming.
  • The Hyper Battle DVD's release date is the same day as Kamen Rider Zero-One's premiere date.
  • At one point The Another Riders perform a dance that is identical to the one seen in Michael Jackson's Thriller video.
  • It is unknown whether the three Another Riders are mirages, or simply ghosts that are identical to the real ones, as they vanish along with the Boy and Girl.
    • Even though they share the same facial appearance, it is confirmed that both of the ghost siblings are not Heure and Ora, thus making this event not linked to the Time Jackers's scheme.
  • This is writer Kota Fukihara's only work in the whole Kamen Rider Series before he passed away.
