Kazuma Kenzaki


 * For the alternate version of Kamen Rider Blade from Decade, visit Kazuma Kendate.

Kazuma Kenzaki (剣崎 一真) is the main protagonist of the Kamen Rider Blade television series. He was chosen by the B.O.A.R.D. organization to use the sealed Category Ace of Spades (Change Beetle) to become Kamen Rider Blade (仮面ライダーブレイド Kamen Raidā Bureido?). He has a good heart and believes in fighting to protect humanity.

In episode 30 and 31 of Kamen Rider Decade, Takayuki Tsubaki (椿 隆之 Tsubaki Takayuki?) reprises his role as Kazuma Kenzaki and again, voice-only role in Movie Taisen 2010.

TV Series
At the age of 11, Kenzaki was orphaned when his family died in a freak fire accident. The powerlessness he felt[ would forever serve as the motivation to try and protect the defenseless, subsequently leading to being scouted by Board Of Archaeological Research Department (otherwise known as B.O.A.R.D.). Because of his intelligence and exceptional survival tactics, he would eventually be promoted to field operative and the designated user of Rider System-02.

However, during assessment for the Rider System, Kenzaki displayed unusually high fusion coefficiency. Though this caused no immediate concern, as his levels maintained steady intervals. After being promoted to Rider status, Kenzaki would be paired with fellow BOARD Rider and senior operative Sakuya Tachibana in hunting down three Undead within a period of two months.

After sealing the Bat Undead, meets a web-journalist named Kotarō Shirai, who begins investigating the Riders after witnessing Kenzaki carelessly changed back from Rider form. To lessen the risk of exposure, and to find a place to board after losing his apartment for not paying his rent in time, Kenzaki made a deal with Kotarō: In exchange for information concerning the Riders, Kotarō would provide a place for Kenzaki to stay; being that his salary with BOARD was barely enough to make a living. But later that evening, disaster struck as BOARD HQ fell under attack from the Locust Undead.

With Tachibana walking off without offering aid and Karasuma, BOARD's president, no where to be found, Kenzaki and Shiori, one of BOARD's surviving members, set-up a new base of operations in Kotarō's home, using whatever equipment left undamaged during the Undead Raid on BOARD HQ. Though operating at a limit capacity, Kenzaki, Hirose, and Kotarō successful began track and sealing any active Undead in the area. But eventually Kenzaki began tracking down his renegade partner Tachibana, leading to an encounter with Chalice, whose attempts to befriend him ended sourly.

Kenzaki was later kidnapped by men working for Isaka(the man behind Tachibana's strange behaviour) to be used in a experiment to test the human/Category Ace fusion ratio by pitting him against the Trilobite Undead, his fusion rate increasing upon seeing Hajime with his captors before Chalice gets involved as well before Garren provides backup. After that Kenzaki learns that Hajime is the Joker Undead, confronting him before they fight until the Zebra Undead start his attack. Though he knew that Chalice was an Undead operating under the alias "Hajime Aikawa", Kenzaki started to believe that there's some good in Hajime and that he's not the monster he originally thought him to be. However, once Griffa Undead was sealed, Hajime begins to lose control and his impulse as Joker comes forth with the Stone of Sealing creating an army of DarkRoaches to eliminate all humans. In the end, Kamen Rider Blade is the only one to combat him head on, both equal in power, intent on saving the Earth and Hajime from himself.

In the series ending, Kenzaki sacrificed his humanity in order to save Hajime, thus becoming the Navy Joker. Hajime is allowed to keep his Human Spirit card to maintain his disguise and stays with the Kurihara family for the rest of his life; but still remembers what Kenzaki has done for him; for if he and Kenzaki cross paths, fate will step in and force them to fight.

Missing Ace
In the movie Missing Ace, however, he was forced to seal Hajime as the Joker Undead, effectively ending the Battle Royale. Four years after, he became a garbage man who witnessed the combat of the New BOARD Riders when the Albino Joker released half of the Undead, eventually joining them back as Blade after Leangle resealed his Category Ace. He asked Leangle to unseal the Joker Undead so as to save Amane from the AlbiRoaches. When she was sealed by the Albino Joker to access Jashin 14, he intended to exchange his life for her, but was pushed over by Hajime to be sacrificed instead. Once more he was forced to seal Hajime to weaken Jashin 14, then killed it and the Albino Joker in it with King Form.

Kamen Rider Decade
About 5 years later (after the series ending), Kazuma shows up in the World of the Rider War in Kamen Rider Decade pointing out that their real enemy isn't Dai-Shocker, appearing just before his equivalent, Kazuma Kendate and the iteration of the World of Blade was destroyed by Apollo Geist's merging of the Rider Worlds. He also has become able to transform into King Form automatically, using only the Blay Buckle and Change Beetle Rouse Card. His transformation screen turns from blue to gold, further emphasising that he is able to assume King Form automatically and the screen comes to him now similar to the "Open Up!" feature rather than Kenzaki running into it.

In Decade: Final Chapter in his regular Ace Form he teams up with Kamen Rider Ryuki to destroy Decade now in Violent Emotion's Form but Decade turns the tables on them by turning Kenzaki into Blade Blade to destroy Ryuki and later destroys him with his Final Attack Ride resulting in both Riders being turned into cards. He is later revived after Decade is voluntarily destroyed.

Forms
He mostly assume as Kamen Rider Blade. As 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.

In final episode of Kamen Rider Blade, he mutated of Navy Joker to put the Battle Fight at a stalemate, thereby ending it without sealing Hajime. This form was never shown.

Gear & Accessories
Blay Buckle Designated "Rider System 02", this transformation device was the second Rider System developed by B.O.A.R.D. intended as a mean to combat the Undead via the fusion of Undead DNA and human DNA. The Blay Buckle was designed for specific compatibility with the ♠A: "Change Beetle" Rouse Card and harnesses the DNA of the Beetle Undead. This model utilizes the "Turn-Up" mechanism to produce a stationary transformation screen, which initiates the fusion of Undead DNA with a human to produce the Kamen Rider transformation. More often than not, the transformation screen itself can act as a deflective wall against assaults.

Blay Rouzer AP Cache: 5000AP; 7400AP (after initiating Jack Form) Blade’s primary armament; a hi-tech saber which serves as a weapon for combat and storage unit for Rouse Cards, including Proper Blanks. It has a built-in 'rousing' technology, which enables Blade to "rouse" the sealed Undead's power to utilize personally. After activating Jack Form, the Blay Rouzer gains an enhancement in the form of a blade extension. Its extended length aside, all of the standard features and functions remain intact, although now its AP Cache has been largely expanded.

Rouse Absorber A special accessory developed by Kei Karasuma to bolster the Rider’s capabilities. The Rouse Absorber was designed to be a supplementary Rouse device to Rider System and specialized container for the top category Rouse Cards. Its system was designed to harness the ♠J: "Fusion Eagle", ♠Q: "Absorb Capricorn" and ♠K: "Evolution Caucasus" Rouse Cards and is only compatible with those cards. Initiating either Jack Form or King Form, modifies the Rouse Absorber with a signature spade-plaque (a spade-eagle plaque for Jack Form; spade-Caucasus plaque for King Form). Though the Rouse Absorber is dubbed King Absorber henceforth, the modification, in either case, proves more cosmetic if anything.

King Rouzer AP Cache: 9600AP (Or maybe more) The King Rouzer is the signature armament of Blade in King Form. Modeled after the broadsword, the King Rouzer is Blade's most powerful Rouzer weapon given its size and weight. That aside, the King Rouzer functions as most Rouzer weapons, although its AP Cache has been given a much larger expansion. Where as Rouze Cards were roused by scanning the cards through the system, the King Rouzer does it differently by having up to five Cards be inserted into the slot where the blade of the Rouzer meets the grip.

Blue Spade
