“The things that change. The things that don’t change. And the things that I wouldn’t want to change.”

Takeshi Hongo was a man with both keen intellect and great fitness. He gained extraordinary power after being transformed into an augmented human being by SHOCKER. While the secret society SHOCKER claimed itself to be all-loving, as well as aiming to pursue happiness for humanity, its true intent was unknown. In the wish to protect human race and let human beings stay “human”, Takeshi Hongo decided to team up with Ruriko Midorikawa and fight against SHOCKER as Kamen Rider.
