Kamen Rider Gaim Gaiden: Kamen Rider Duke

Kamen Rider Gaim Gaiden: Kamen Rider Duke (仮面ライダー鎧武 (ガイム) 外伝: 仮面ライダーデューク) is the spin-off featurette focusing on the character of Ryoma Sengoku (Kamen Rider Duke), released alongside Knuckle as part of the second double set of Kamen Rider Gaim Gaiden, a series of V-Cinema (direct-to-video) releases that each serve as a spin-off hosted by a supporting Kamen Rider from Kamen Rider Gaim.

Premium Bandai then announced the DX Lemon Lockseed as well as a Kamen Rider Duke faceplate, which would be included in the DVD/Blu-Ray release.

Continuity and Placement
In the case of Duke, this Gaim Gaiden installment serves as a prequel to the Gaim series.

Plot
Ryoma Sengoku continues his research of the Sengoku Drivers along with Takatora Kureshima. Takatora thinks that the lives of humanity was the number one priority, however Ryoma disliked his way of thinking increasing the production with cost as the main priority than efficiency.

Meanwhile Sid and Yoko investigate a suicide attack that was taking place in Yggdrasill. The mastermind of this incident was Black Linden. They come to know that one of Ryoma's former colleague was part of Black Linden and had used the Zakuro Lockseed to brainwash people. Ryoma knows this is impossible, because his former colleague died in the Out-of-Control Lockseed incident a long time ago.
