Toei has posted the announcement for the next straight-to-video Kamen Rider Gaim Gaiden films.
Taken from the Kamen Rider Zangetsu/Kamen Rider Baron Live Talk Event, Yuki Kubota (Takatora/Kamen Rider Zangetsu) and Yutaka Kobayashi (Kaito/Kamen Rider Baron) announce the second V-Cinema starring Tsuneori Aoki (Ryouma/Kamen Rider Duke) and Gaku Matsuda (Zack/Kamen Rider Knuckle).
Kamen Rider Gaim Gaiden: Kamen Rider Duke/Kamen Rider Baron will be released on DVD and Blu-Ray in Japan on November 11th. Both format versions of the film will come in standard and Lockseed Editions, the latter containing the non-Energy (and cast voiced) Lemon Lockseed and a Kamen Rider Duke Faceplate for the DX Sengoku Driver.
