Recently, the identity of the new Kamen Rider Grease was finally revealed. Yet, for those who have not been following the Kamen Rider Build television series, Grease is the third Rider that will appear in the series. This character’s information has been teased since mid to late fall through various toy catalogue and magazine scans. Now, unlike Kamen Rider Build, Kamen Rider Grease will be using the Sclash Driver and the Sclashjellies to transform rather than the Build Driver and Full Bottles. His signature weapon is known as the Twin Breaker.
Now, as for the identity of Kamen Rider Grease, it is Saruwatari Kazumi who will be portrayed by Kohei Takeda. Kamen Rider Grease is stated to a secret assassin hired by Hokuto. According to Natalie, Saruwatari Kazumi will debut in episode 17 of Kamen Rider Build, which will air on January 7, 2018.
Longtime fans of Kamen Rider will know Kohei Takeda as Otoya Kurenai, Wataru Kurenai’s father from Kamen Rider Kiva. In addition, as Otoya Kurenai, Takeda could transform into both Kamen Rider Ixa and Dark Kiva. However, Takeda also portrayed Wataru’s son in the series epilogue, as Kamen Rider Kiva of 2031.
