This article refers to Kamen Rider Blade, Kazuma Kendate, as he appears in Kamen Rider Decade. For the original Kamen Rider Blade, visit Kamen Rider Blade (Rider).
Kazuma Kendate (剣立 カズマ, Kendate Kazuma) 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, Kamen Raidā Bureido) 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 when 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.
Since Tsukasa Kadoya possesses a Blade card, he can transform Kazuma himself, as Blade, or a doppelganger into Blade Blade, a giant sword.

However, in spite of Yuusuke's encouragement, the stress of working in the kitchen and being demoted again to rank 2 gets to Kazuma as Hajime demands him to relinquish his Blay Buckle.

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 Yuusuke, 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. --Rider War: Prologue
Forms
Just like the original Blade, he harnesses the Beetle Undead DNA from the ♠A: "Change Beetle" Rouse Card, utilizing the Blay Buckle Rider System to fuse with the Beetle Undead's DNA. With the Blay Rouzer saber, he can "rouse" a sealed Suit-Spade Undead's power to utilize personally or use Proper Blanks to seal the Undead. Kamen Rider Decade's Final Form Ride allows Blade to change into Blade Blade (ブレイドブレード ,Bureido Burēdo?), a giant version of his Blay Rouser.
