Kazuma Kenzaki

"Tachibana! Why are you watching? Have you really betrayed us?!"

- his words when Garren seemingly betrays BOARD

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 to become Kamen Rider Blade (仮面ライダーブレイド). He has a good heart and believes in fighting to protect humanity.

TV Series
At the age of 11, Kenzaki was orphaned when his family died in a house-fire. The powerlessness he felt would forever serve as the motivation to try and protect the defenseless, subsequently leading to being scouted by the B oard O f A rchaeological R esearch D epartment (otherwise known as B.O.A.R.D.). Because of his intelligence and exceptional survival instincts, 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 partnered with fellow BOARD Rider and senior operative Sakuya Tachibana on assignment to hunt down three Undead over the next two months.

Eventually sealing the Bat Undead, Kenzaki meets a web-journalist named Kotarō Shirai, who begins investigating the Riders after witnessing Kenzaki carelessly changing back from his transformation. To lessen the risk of exposure (and to find a place to board after losing his apartment due to delinquent payments), Kenzaki made a deal with Kotarō: In exchange for information concerning the Riders, Kotarō would provide him a place 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's desertion and Karasuma--BOARD's president--no where to be found, Kenzaki and Shiori Hirose, one of BOARD's surviving staffers, set-up a new base of operations in Kotarō's home, using whatever equipment left undamaged during the Undead assault on BOARD HQ. Though operating at a limit capacity, Kenzaki, Hirose, and Kotarō successfully began tracking and sealing any active Undead in the area. But eventually Kenzaki redirects his focus on tracking down the rogue Tachibana, leading to a rivalry with a being named Chalice, who possesses similar powers & abilities to his Rider System. Their frequent encounters led to the discovery that Chalice was in fact a human named Hajime, but the origins of his powers and his motives remained a mystery at the time.

Kenzaki was later abducted by agents of a man named Isaka (the man responsible for Tachibana's strange behavior) who intended to used him in human/Undead fusion research. Kenzaki was forced into combat with the Trilobite Undead, and his fusion rate remained stable until Hajime appeared among his captors. Isaka witnessed a spike in Kenzaki's fusion ratio causing Hajime to transform and intervene, along with Tachibana. Hajime is revealed to be not human at all, but, in fact, the Joker Undead. Yet despite this knowledge, Kenzaki started to believe that there's some good in Hajime and not the monster he originally thought. 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 Dark Roaches 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, despite Hajime's pleas to Kenzaki to seal him once and for all to save the world, Kenzaki opted to sacrifice his humanity through excessive use of King Form in order to both save the world and Hajime, thus becoming a Joker himself. 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. The show ends with an engine running and motorcycle tire tracks in the desert, most likely to be made by Kenzaki riding his Blue Spader away from humanity.

Missing Ace
In an alternate ending to the final episode, 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 Albi Roaches. 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 appears as one of the nine Heisei Riders in Kamen Rider Decade then battle Tsukasa after Wataru told him to destroy nine Heisei Riders as true goal.

All Riders vs. Dai-Shocker
To stop the fusion and destruction of worlds, Tsukasa Kadoya, announced a tournament gathering all Riders to learn who was the strongest. Blade participated in the tournament fighting against Kamen Rider Stronger.

''In the manga adaptation, Blade fought against Skyrider rather than Stronger. He was also in his Jack Form rather than the standard Ace Form.''

Rider War
Kazuma shows up in the World of the Rider War 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 ♠A: Change Beetle Rouze Card. His transformation screen turns from blue to gold, further emphasizing 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.

Final Chapter
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.

OOO, Den-O, All Riders: Let's Go Kamen Riders
Kamen Rider Blade appears yet again in OOO, Den-O, All Riders: Let's Go Kamen Riders, fighting against Undead that allied themselves with Shocker and other Kamen Rider villains from the 40 years of the franchise.

Although his human form isn't shown in the movie itself and he doesn't speak, Blade is confirmed to be Kazuma Kenzaki by the movie's official website.

Kamen Rider × Super Sentai: Super Hero Taisen
Blade, along with All Riders (until Fourze), tagged along with core Super Sentai members to fight Dai-Zangyack and Dai-Shocker. He is last seen using Refleclear (Gosei Blue's Power Cards) to counter Kani Laser's attack and use his Rider Kick (it's unknown if it is Lightning Blast or Lightning Sonic) along with Decade's Dimensional Kick and Ryuki's Dragon Rider Kick.

Kamen Rider Wizard
Blade appears with all the Heisei Riders from Kuuga to Fourze, led by Decade, in a special two-parter after the finale, The Ring of Kamen Rider and Neverending Story.

Forms
As Blade, he harnesses the Beetle Undead DNA from the ♠A: Change Beetle Rouze 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 the final episode of Kamen Rider Blade, he mutated into a Black Joker to put the Battle Fight at a stalemate, thereby ending it without sealing Hajime. This form was never shown in the series but was released in later materials such as the S.I.C. Hero Saga and Kamen Rider Blade novels.

Blay Buckle
Designated "Rider System 02", the Blay Buckle (ブレイバックル) was the second Rider System developed by B.O.A.R.D. intended as a means to combat the Undead via the fusion of Undead & human DNA. The Blay Buckle was designed for specific compatibility with the ♠A: Change Beetle Rouze 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 (Jack Form)

The Blay Rouzer (ブレイラウザー) is Blade’s primary armament; a hi-tech saber which serves as a weapon for combat and storage unit for Rouze Cards, including Proper Blanks. It has a built-in 'rousing' technology, which enables Blade to "rouse" the sealed Undead's power to utilize personally. Blade utilizes Rouze Cards' abilities by slashing the cards onto the blade's side, similiar to the Ryuki's Kamen Rider Alternatives' Slash Visor. 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.

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

King Rouzer

 * AP Cache: 9600AP

The King Rouzer (キングラウザー) is Blade's signature armament in King Form. Modeled after the broadsword, the King Rouzer is Blade's most powerful Rouzer weapon given its size and weight. The King Rouzer's voice, when inserting a card, changes and states the card's category and number instead of stating the name . 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 Spader


The Blue Spader is a motorbike developed by B.O.A.R.D. specifically designed to the aspects of Kamen Rider Blade's Rider System. The Blue Spader is fitted with limited Rouzer technology, enabling augmentation to certain aspects of its performance with different performance modes.

Extreme Shot Was not used in the series, so this combo's abilities remain unknown, but considering the sheer amount of the AP this combo costs, it is possibly a last-resort attack, as it would nearly completely drain Blade's AP Cache in Ace form, with a mere 200 AP left.
 * Cards Required: Thunder Deer (♠6) + Fire Fly (♦6) + Tornado Hawk (♥6) + Blizzard Polar (♣6)
 * AP Cost: 4800 (♠6=1200, ♦6=1000, ♥6=1400, ♣6=1200)

Portrayal
Kazuma Kenzaki is portrayed by Takayuki Tsubaki (椿 隆之). He reprised this role in Kamen Rider Decade. As Kamen Rider Blade, his suit actor was Seiji Takaiwa (高岩 成二), who has been the suit actor for the majority of leading Heisei Kamen Riders (except Kuuga and Hibiki).
