Ride Booker

Decade's primary weapon is the Ride Booker (ライドブッカー) which has three modes: the default Book Mode (ブックモード), which is placed on the left side of his belt and holds the Rider Cards that Decade uses in his arsenal, Gun Mode (ガンモード) which can be used to execute the Dimension Blast (ディメンションブラスト) finisher and Sword Mode (ソードモード) which can be used to execute the Dimension Slash (ディメンションスラッシュ) finisher.

When fighting Gyūki, Decade briefly fought as Ryuki with a red bullfighting cape adorning the blade of Sword Mode. In either Mode, Decade primarily uses the Ride Booker in the place of the Heisei Kamen Riders' signature weapons, bladed or firearms.
