Gaim and Kikaider share the screen in this crossover episode of Kamen Rider Gaim: The Red and Blue Kikaider.
Episode 30: The Red and Blue Kikaider
Writer: Nobuhiro Mōri
Director: Ryuta Tasaki
Kōta and Mai encounter a strange youth. When trying to cover themselves from rain, they make physical contact with the youth, it feels just like metal. Is he a robot? Apparently having lost his memory, the youth seems to remember only his own name, Jirō. Kōta, not able to leave someone like this, decides to take him into his home until he remembers something.
Meanwhile, Ryōma, facing an unfamiliar android, seems quite pleased. The android, entrusted to him by a fellow scientist to run a final test, has the unique design of a robot designated as “Kikaider” input in his memory.
Who is Jirō? Who is the android with Ryōma?

Aww, come on…We already seen Gaim with the Showa Riders and Tokkyuger. What’s wrong with seeing Gaim again with some other Showa Heroes Revived? 😉
Why would they do something like that T_T *hides in a corner
