Masahiro Inoue (井上正大) previously portrayed Tsukasa Kadoya/Kamen Rider Decade. He appeared in a show that had a similar premise to the currently airing show Kamen Rider ZI-O. Decade used the powers of previous Kamen Riders with cards, while ZI-O uses Ride Watches.
Inoue will reprise his role in upcoming episodes of Kamen Rider ZI-O. Unlike other past Riders who have helped ZI-O defeat their Another version enemies, Decade isn’t so friendly.
Woz is feeling pressured as he watches ZI-O succeed time and time again and knows the future is bound to change. To achieve his goal, Woz recruits a “person who can destroy everything and change the future.” He seeks the help of Kamen Rider Decade, including giving him a modified transformation Decadriver belt that will allow him to transform into Kamen Rider characters after his original debut.
Inoue will appear in the 13 and 14th episodes, which is styled after Kamen Rider Ghost’s world, but also into episode 15.
