PLOT
The 35th Masked Rider Anniversary File is Kamen Rider's equivalent to the Super Sentai Series' The 30 Sentai Encyclopedia, a series of featurettes that aired at the end of each episode of GoGo Sentai Boukenger, the Super Sentai show which aired alongside Kamen Rider Kabuto celebrated the 30th anniversary of the Super Sentai Series.
This segment acted as a look back to the Kamen Rider franchise and an early advertisement for the God Speed Love movie. During these five segments, the characters discuss the history of the Kamen Rider franchise, sometimes in a comedic tone, but always with serious background music.
Like the Sentai Encyclopedia, the Anniversary File is not included as part of Kabuto on home video or streaming.
