Kazuma Kendate

''This article refers to Kamen Rider Kiva, Kazuma Kendate, as he appears in Kamen Rider Decade. For the original Kamen Rider Blade visit Kamen Rider Blade (Rider), Kazuma Kenzaki''

Kazuma Kendate (剣立 カズマ) is a Rank Ace employee of BOARD who has the ability to transform into Kamen Rider Blade (仮面ライダーブレイド) with the sealed Beetle Undead. However, due to his ranking, Kazuma is prideful to the point of seeing himself to be invincible. It is not until after he gets demoted while Tsukasa Kadoya arrives that he realizes that ranking is not everything and that followers are just as important as leaders. Soon after helping him with the crisis occurring in his world, Kazuma thanks Tsukasa who is confident that he would look after the Ace Lunch. He sometimes calls Tsukasa "cheese", rather than "chief", though it is not known if this is made purposefully or not.

Kazuma later appears in the World of the Rider War as his reality is absorbed into it, leading his Rider comrades against Wataru's. Though at first he refuses to aid Tsukasa and Yusuke, Kazuma has a change of heart and joins in the fight against Super Apollo Geist with Kamen Rider Garren before the villain causes more worlds to merge into the World of the Rider War, destroying the World of Blade which causes its Riders to fade away as a result.

Since Tsukasa Kadoya possesses a Blade card, he can transform Kazuma himself, as Blade, or a doppelganger into Blade Blade, a giant sword.
