A new Kamen Rider series has been confirmed for this Fall. It is going to be called Kamen Rider Fouze (仮面ライダーフォーゼ ), Fouze = four (4) & zero (0). Kamen Rider 40! Well.. whatever the title means, I am eagerly anticipating this new series.
Some info from what is known thus far about the series (Source: Jetfusion):
First rumored as Kamen Rider Dragon, it is finally confirmed that the 13th Heisei Kamen Rider will be called Kamen Rider Fouze. The trademark had been registered on May 19, 2011.
No other information have been confirmed up to this post. But as per previous rumors, D-Boys member Ryuki Takahashi is slated to play a high school student who suffers from memory loss. He inherited the Kamen Rider Fouze Rider System from his father to fight "Noa."
Accordingly, Kamen Rider Fouze will be stylized as Kamen Rider 40, with "40" be read as "Fouze," "Four-zay" or something along those lines. But this one doesn't show up in the registration, unlike Kamen Rider OOO's.
