Plot
The story sees the Kamen Riders helping brother and sister Reito (レイト, voiced by Aoi Yuki (Younger version)) and Reina (レイナ, voiced by Rie Tanaka) to restore Reito's memories by reliving the events of the Kamen Riders' various movies. The two siblings are assisted by Cinema (シネマ, Shinema, voiced by Keiji Fujiwara), who is ultimately revealed to be the game's main antagonist who is more interested in filming the Kamen Riders for an unknown purpose.
