One of the obvious problems with summer Kamen Rider movies introducing new characters (most of whom are Riders themselves) is that they rarely have time to develop them in a meaningful way. But with the arrival of streaming services such as the Toei Tokusatsu Fan Club, there's an opportunity to give them a bigger spotlight through prequel specials that can add a little more context to things. For example, just ahead of the release of Kamen Rider Revice: Battle Familia, the service launched (the rather lengthy titled) Kamen Rider Revice Movie Spin-Off Delivered Drama: Birth of Chimera – introducing fans to the characters that will be driving the plot of the film.
