Fictional character biography

TV Series

At the age of 11, Kenzaki was orphaned when his family died in a house fire. The powerlessness Kenzaki felt would serve as the motivation to try and protect the defenseless, subsequently leading him to be scouted by the Board Of Archaeological Research Department (BOARD). 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. However, later that evening, disaster struck as BOARD HQ fell under attack from the Locust Undead.

With Sakuya's desertion and Kei Karasuma--BOARD's president--nowhere to be found, Kenzaki and Shiori Hirose, one of BOARD's surviving agents, 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, Shiori, and Kotarō successfully began tracking and sealing any active Undead in the area. However, 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.

Events escalated when Kenzaki finds himself abducted by agents of a man named Isaka (the man responsible for Tachibana's strange behavior) as the subject of study for his human-Undead fusion research. Kenzaki was forced to transform and battle against the Trilobite Undead, while his captors monitored his fusion activity. As the battle progressed, Kenzaki showed no changes in fusion stability until Hajime appeared. This cause a noticeable spike in Kenzaki's fusion activity which curiously effected Hajime as well, spurring him to transform and intervene, along with Tachibana. During the course of their battle, the mysterious Hajime is revealed to be non-human, despite the previous speculation and was, in fact, a being called the Joker Undead. Gradually, Kenzaki begins to empathize with Hajime, recognizing him as more than a mindless monster.

As the Riders continued their exploits, Kenzaki and Tachibana would reconcile their grievances and begin operating with each other once more after rescuing Professor Karasuma. They would also find a new ally in Hajime, after a number of encounters and even recruit a new Rider with Mutsuki Kamijo as Kamen Rider Leangle, along the way. However, with the emergence of the Trial Series, Kenzaki (along with his colleagues) would discover the true circumstances behind the emergence of the Undead and the Battle Fight. Recognizing the true natue of the Battle Fight, the Riders would devise a plan to ensure the survival of humanity by allowing Hajime (in Human Undead form) to be the last remaining Undead at the end of the Battle Fight contest. Confident of their plan, the Riders would continue sealing the Undead until the BOARD chairman Hiroshi Tenno revealed himself as the true mastermind of the new Battle Fight. Confident that he would win, Tennouji then told the Kamen Riders of the Kerberos Undead's existance, an Undead who surpassed even the Joker Undead in might. While initially overwhelmed, Kenaki's determination allowed him to overpower Tennouji and the Kerberos Undead in battle, defeating them with help from his allies. Soon after, the Giraffa Undead would kill Tennouji and steal the sealed Krberos Undead's card, attempting to seal Hajime to be declared the new victor of the Battle Fight. With Tachibana's actions though, Kanai would be sealed as well, causing the Joker Undead to be the only unsealed Undead in the world. With all Undead finally sealed, the Stone of Sealing materialized and declared the Joker Undead the winner of the Battle Fight, despite Hajime using the power of the Human Undead at the time. Using its power, the Stone of Sealing began spawning legions of Dark Roaches to ravage the world.

Kenzaki, alongside the other Riders, fought desperately to contain the Dark Roach hordes. They fought valiantly but were ultimately overtaken. Kazuma would find Hajime and the two would engage in combat. However, Kenzaki's objective was not to seal Hajime. Since the Dark Roach Army emerged, he had been using his Rider System's King Form to accelerate his mutation into a full Joker Undead. Being fully aware of the consequences, Kenzaki realized that as long as two Undead remained, the Battle Fight could continue indefinitely as long as he and Hajime avoid combat with each other. His strategy worked, and the Dark Roaches were removed by the Stone of Sealing, allowing the world to continue existing. Horrified at what he had indirectly caused Kazuma to do, Hajime reached out to him. Yet, Kenzaki told him to stay away, assuring his friend through a faint smile before leaving.

Kenzaki's sacrifice enabled Hajime to keep the Human Spirit card and maintain his disguise while living among the Kurihara family and would forever be indebted to him. Kenzaki on the other hand, having sworn to win against his destiny as an Undead, left to parts unknown.

Kamen Rider Decade

Near the end of the series, Kenzaki would reappear in the last two episodes of Kamen Rider Decade. His actual nature and origin have received conflicting explanations in written material. He has both been described as the original Kazuma Kenzaki, after living in solitude for years ^[1] or more recently is suggested to be a separate A.R. World version of the original Kazuma Kenzaki^[2] ^[3] . Showing up in the World of the Rider War just after his equivalent, Kazuma Kendate and the iteration of the World of Blade was destroyed by the merging of the Rider Worlds, Kenzaki revealed to Tsukasa's group the true root of their problem; Decade's presence. With the situation growing more dire by the second, Kenzaki then immediately transformed into Blade King Form and attacked Tsukasa, telling him to leave the world that they were in. With Natsumi still held hostage by Dai-Shocker, Tsukasa refused and retaliated as Decade. With none of his allies assisting him, Tsukasa was swiftly defeated by Kenzaki, sustaining severe wounds in the process. Yet, Tsukasa remained adamant to save Natsumi, despite Kenzaki's continued warning to him. Later on, with Tsukasa having failed to stop the alternate alternate worlds from merging, Kenzaki would reappear to him once more, attacking him again alongside the other original Nine Heisei Riders.

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. Kamen Rider Decade: All Riders vs. Dai-Shocker

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

OOO, Den-O, All Riders: Let's Go Kamen Riders

A mishap caused by the Greeed Ankh unintentionally altered the timeline which enabled Shocker to utilize the Core Medal to create the Shocker Greeed which defeated the Double Riders and seemingly erased the legacy of the Kamen Riders from history. In 2011, after Kotaro Nogami's attempt to repair the damage, he along with Kamen Rider OOO and M-Ankh awaited execution. However, it was revealed the Double Riders had their brainwashing removed by a Shocker scientist.

The Double Riders joined with New Den-O and OOO to fight Shocker's forces but were eventually defeated. When the order was given to kill everyone, V3 suddenly appeared, asserting that there were more than four riders. V3 was soon followed by all the other revived riders that came after him, including Blade, as even though Rider's history was changed, the people's memories haven't changed.

After the riders were united, they faced off against Shocker's Great Leader. Later, when joined by a force of extra riders, Blade and all the other riders got on their motorcycles and performed the "All Rider Break", ramming into the Rock Great Leader and defeating it once and for all.

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.

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.

Despite the fact that it was not shown in the movie itself, Blade was killed by a Showa Rider and was turned into a Lockseed.

Blade later appeared when Gaim and ZX released all of the Kamen Riders from their Lockseeds. Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai

Super Hero Taisen GP: Kamen Rider 3

In a timeline alteration, after Shocker gained their victory, most Riders had been placed under their control with Leangle leading a small portion of their army. Kamen Rider Blade was claimed to be imprisoned by Sakuya during their infiltration to Shocker's base. However, it was revealed to be a lie as Sakuya was already an evil rider alongside Kazuma. Soon Kazuma alongside Sakuya, Hajime, and Mitsuki had their hearts changed despite still brainwashed after they couldn't accept how Shocker treated its own allies and aiding Drive.

After Takeshi Hongo and Hayato Ichimonji broke free from the Rider Robo, their brainwashing was fully destroyed.

Surviving the onslaught of the History Modifying Machine, Blade fought and destroyed Shocker's N-Gamio-Zeda with the Lightning Blast shortly before the Rider Robo was destroyed along with the machine by Shurikenjin Tridoron. Among the remaining Riders who witnessed the farewell of Kyoichiro Kuroi as the perversion of history was reversed, Blade's place in history was restored.

Kamen Rider Ghost: Legendary! Riders' Souls!

Despite not appearing in the web-exclusive series, Ghost can use the power of 16 Heisei Riders, including Blade, with the Heisei Rider Damashii in the final episode.

Kamen Rider Ex-Aid "Tricks": Kamen Rider Genm

Despite not appearing in the web-exclusive series, Blade and 13 Heisei Riders were the projections of the Ganbarizing Critical Strike.

Kamen Sentai Gorider

"Indeed your plan is a success, but you made one big mistake. My power that you used is an Undead power which has lured me to come here. Aside from that, you erased the Undead power, making only one Undead triumph in this world by default, me. And to make it worse, I am an Undead that brings the destruction of the world should I be the winner, Joker"

― Kenzaki explained the greatest mistake of Kuroto Dan's plan^[src]

Blade is one of five dead riders who have been brought into another dimension, along with a still alive Emu Hojo. Though Kazuma is technically still alive as an Undead, he considers losing his humanity to be his "death".

As it turns out, however, Kenzaki isn't who he appears to be as he stabs Emu in the abdomen with his Blay Rouzer. Before Emu narrowly escapes with his life, "Kenzaki" drops his disguise and reveals himself to Emu. Kuroto Dan turns out to be the one disguising himself as the Undead Kamen Rider, but the real Kenzaki eventually shows up to help the heroes and also still alive as the mirror reflection reflects himself, having found the "impossible" Game World's entrance in CR by sensing Kuroto's use of Undead powers. Due to Kenzaki being the only Joker Undead within the Game World, the rules of the Undead Battle Fight applied to the Game World and began its destruction. During the final fight against Genm and Totema, Blade and the other four deceased Kamen Riders are given the Gorider's cards to become Kamen Sentai Gorider, with Kenzaki becoming Ao-Rider. At the conclusion of the fight, Blade prevents Ex-Aid from stopping the four deceased Kamen Riders sacrifice themselves to defeat Genm. Both Blade and Ex-Aid escape the Game World right after Genm's defeat. Though it is unknown what happened to Kenzaki afterward, it can be assumed he left CR right after returning to the real world.

Personality

Kazuma Kenzaki is a friendly, cheerful man. Partly due to his traumatic past, Kazuma had a somewhat awkward side at first, struggling to befriend others. Furthermore, he has shown himself to be quite naive. Despite all this, Kazuma genuinely does care for the well-being of others and will go to great lengths to help those in need. His vow to never let an innocent person feel pain if he can help it is what motivates Kazuma to fight against all odds, hoping to save all those in need.

The guilt Kazuma felt for his inability to save his parents have continued to haunt him for years, the tragedy having reappeared in his dreams at one point. This feeling of guilt though was slowly soothed by the friends that supported him. As the series progressed, Kazuma matured greatly, even becoming a sort of mentor for Mutsuki Kamijo/Kamen Rider Leangle.

Humorously, Kazuma (along with Mutsuki) in Missing Ace once tried to steal from the now rich Kotarō hinting a slightly devious side.

In the novel, Kamen Rider Blade: Twilight, over the years, Sakuya Tachibana/Kamen Rider Garren would hear of a strange creature saving children and other people all throughout the world, said strange creature hinted to be Kazuma as an Undead.

In Kamen Rider Decade though, Kenzaki had a drastic personality change as he went from kindhearted to cold and cynical. This is noted by director Shōji Yonemura in 「ライダー40年の歩み 40　YEARS CHRONICLE」 to have been the result of turning into a Joker Undead and parting with all his friends. No longer having any qualms about ending a person's life, Kenzaki mercilessly attacked Tsukasa Kadoya/Kamen Rider Decade and nearly killed him. However, despite his cold personality, Kenzaki did give Tsukasa the option of leaving peacefully, hinting that he still had some good left inside. Indeed, Kenzaki's actions toward Tsukasa were not out of malice, but simply because of the urgency of the situation.

In Kamen Sentai Gorider, he is shown to be an ally of justice, helping Emu Hojo/Kamen Rider Ex-Aid and the four deceased riders stop Kuroto Dan from reviving himself and taking over the world with Bugsters. Though fighting as an ally of justice, Kazuma stopped Emu from preventing the sacrifice of the four deceased riders, as he felt it to be necessary to foil Kuroto's plans.

Unlike previous guest appearances, in the Kamen Rider Blade -The Whereabout of Trump, Kazuma is mostly the same as he was ten years ago. Still a friendly and cheerful man, Kazuma continues to wander around the world, helping those in need. While managing to retain his sense of self, Kazuma has worries of losing control over his Undead instincts, which makes him not stay in one place for too long.

In a possible future three hundred years later, as depicted in the Kamen Rider Blade novel, Kazuma's cynicism has overridden him. Having lived for so long through countless wars and battles without anyone to rely on, this Kazuma became hopeless and defeated, often trying to find ways to kill himself and failing every time due to becoming the Joker Undead. This Kazuma had lost sight of himself and the meaning of his actions as his own death would mean the end of humanity and other life on Earth. During the novel, Kazuma becomes an amnesiac due to the manipulations by the Stone of Sealing, helping him fight again as a Kamen Rider. Yet as time passed by, Kazuma slowly regained his memories and began losing his sanity once more. Before the final fight, the Stone of Sealing used Kazuma's diminishing sanity against him and caused him to turn into the Darkness Undead. It was only by Hajime's actions as the Crimson Undead that Kazuma broke free from the Stone of Sealing's influence, restoring his sanity in the process. Once the Battle Fight had ended once and for all, Kazuma no longer felt burdened as the second Joker Undead, as he was now freed from his Undead instincts.

When reappearing in Kamen Rider Zi-O though, Kenzaki had changed greatly for the worse. Due to Hajime Aikawa/Kamen Rider Chalice's actions, Kenzaki was influenced by his Undead instincts, becoming angry and cynical. This is to the point of showing little care towards the possibility of humanity's extinction, something unthinkable in the original series. Instead, Kenzaki seemed focused solely on defeating Hajime, despite the latter's pleas to stop. This shows that Kenzaki had ultimately succumbed to his Undead instincts, despite having managed to retain his sense of self in the original series. Despite this aggressiveness, Kenzaki was shown to be regretful at having to fight against Hajime, as well as being slightly concerned with Amane's predicament.

Once his mutation as the Joker Undead was reversed, Kazuma no longer became bound by the Battle Fight's effects, effectively losing his former aggression. In a somewhat calm but satisfied manner, Kazuma even stated his gladness at being released from his Undead instincts.

Combat Skills

Initially, Kenzaki was an inadequate fighter, barely proving a match against even the weakest Undeads in battle. Gradually though, the experience he accumulated throughout the series would turn Kenzaki into a formidable Kamen Rider, to the point of defeating the powerful Caucasus Undead in Ace Form without any power-ups whatsoever. Even against other formidable foes such as the Joker Undead, the Keroberos Undead, Kamen Rider Wild Chalice, as well as a weakened Jashin Fourteen and Tsukasa Kadoya/Kamen Rider Decade, Kenzaki would prove to be the victor, managing to overwhelming each in combat.

Jack Form (ジャツクフォーム, Jakku Fōmu) is a combat extension of the Rider System which harnesses the power of Category Jack Rouse Cards via the Rouse Absorber. Blade assumes his Jack Form by inserting the Absorb Capricorn Rouse Card into the Rouse Absorber and scanning the Fusion Eagle Rouse Card. This endows the Rider Armor with the attributes and characteristics of the Eagle Undead's DNA, enhancing Blade's combat capabilities.

In this form, Blade gains golden reinforced armor plating which increases his resilience to enemy attacks. Blade also gains wings on his back, enabling him to fly. Assuming this form additionally upgrades the Blay Rouzer into its Empowered Type, which lengthens its blade and expands its AP cache.

King Form (キングフォーム, Kingu Fōmu) is the ultimate combat extension of the Rider System, which only Blade can assume. This transformation is initiated by inserting the Absorb Capricorn Rouse Card into the Rouse Absorber and scanning the Evolution Caucasus Rouse Card. It is undoubtedly Blade's strongest form, allowing him to overwhelm the Joker Undead, Kamen Rider Wild Chalice as well as defeat the Kerberos Undead, and Jashin Fourteen with the support of other Riders.

When transforming into King Form, all of Blade's Spades Suit Rouse Cards form a full suit of golden armor for him. This massively increases his defenses, but at the cost of agility. In addition, Blade can activate the effects of the individual Rouse Cards on his body without having to scan them.

This form grants Blade the King Rouzer. The King Rouzer does not have storage for cards like the Blay Rouzer, as all of Blade's cards are fused with his body. For Rouse Combos, Blade can separate the necessary Rouse cards from his body. Blade is still able to use the Blay Rouzer, and often dual-wields both the King Rouzer and Blay Rouzer.

King Form was designed to only fuse the user with the DNA of the Caucasus Undead via the Evolution Caucasus Rouse Card. However, Kenzaki's unusually high fusion compatibility resulted in him fusing with DNA of all 13 Spades Suit Undead. As a result, extended activity in this form continually raises his fusion rate, ultimately transforming him into a Joker-type Undead. Because of this, Kenzaki was cautioned against using King Form too often. However, Kenzaki intentionally used King Form to turn himself into an Undead and prevent the Battle Fight from ending. Thus, he no longer suffers any side effects from using this form

Rider Statistics

Rider Length: 280 cm.^[5]
Rider Weight: 101 kg.^[5]

Via the Final Form Ride Card Blade Blade, Kamen Rider Blade would transform into Blade Blade (ブレイドブレード, Bureido Burēdo), a large sword similar to the Blay Rouzer.

With the Blade Blade, Decade performs the Decade Edge (ディケイドエッジ, Dikeido Ejji), where the Blade Blade charges with electricity before being slashed down to make a huge electric shockwave similar to Blade's Lightning Slash. When Diend uses the Blade Blade, Diend can perform the Diend Edge (ディエンドエッジ, Diendo Ejji), which is the same as the Decade Edge.

So far, this form appeared twice, once via Diend in Kamen Rider Decade: All Riders vs. Dai-Shocker and second in Movie War 2010 during his and Ryuki's assassination attempt on Decade but backfired and forcefully killed Ryuki in this form before being eliminated via Decade's Dimension Kick.

Appearances: All Riders vs Dai-Shocker

Leangle

In episode 16, when Kotaro accidentally opened the Leangle Buckle, Kenzaki came into contact with the projection produced by the belt and temporarily transformed into Leangle, though he is not wearing the Leangle Buckle on his waist. After a while, the projection sent Kenzaki flying back into a distance.

Joker

Statistics

Height: 219 cm.^[9]
Weight: 108 kg.^[9]

Joker (ジョーカー, Jōkā) (called "Navy Joker" by the fandom) is a mutation caused by excessive usage of Blade's King Form. During the final episodes, he began using King Form excessively to the extent that he would use it right from the start of a fight to ward off mere Darkroachi, even if it put a huge strain on his body. It was revealed in the final episode that he did so deliberately to lead the Battle Fight into a stalemate, by discarding his humanity and transforming himself into a Undead, so as to allow Hajime to live as a human and saving the world at the same time. Because he had mutated into an Undead, Kenzaki can currently use Blade's powers more efficiently as well as gained the standard powers of a Joker Undead. Unlike Hajime who struggles to control his instincts as the Joker Undead, Kenzaki appears to be able to retain his sense of self without using any Rouse cards.

In this form Kenzaki is armed with a sword identical to that of the Caucasus Undead.

Even though Kenzaki was seen with his own Chalice Rouzer in Kamen Rider Blade's finale, his Undead form was never shown in the series. However, it later appeared in a S.I.C. Hero Saga story Kamen Rider Blade: Day After Tomorrow, only to reveal that Kenzaki's Joker form looked exactly like Hajime's. In the Kamen Rider Blade Novel though, it was stated that Kenzaki's Undead form more closely resembles the Beetle Undead and Caucasus Undead. Thus, what Kenzaki's Undead form looks in design is still up for debate among fans.

Powers and Abilities

Biological Immortality: As an Undead, Kenzaki can survive from any physical injuries, no matter how grave they may be.
Human Disguise: Since Kenzaki is an Undead resulted from mutation, he can shift himself from his human to Undead form, making him similar to Royal Club Undeads.
Undead Mimicking: Similar to Hajime, Kenzaki (as the Joker Undead) would in theory be able to use a sealed Undead's Rouse Card to obtain said Undead's form and powers.
Danger Intuition: During his half transformation into an Undead around the series, Kenzaki seemed to develop a symbiosis with the original Joker, Hajime Aikawa where he can sense his defeat at the hands of Kerberos.
Undead Tracking: As Undeads are attracted to each other, he was able to track Genm to the Game World as he used Blade system.
Security Door Unlocking: Somehow, he can break the security system of CR when touching the control panel and open the door.
World Destruction: As a Joker, if he is the only Undead existing in a world, that world will be destroyed. He used this power to destroy the Game World, transforms it into a desolated land and thwarts Genm's plan.

Behind the scenes

Portrayal

Kazuma Kenzaki is portrayed by Takayuki Tsubaki (椿隆之, Tsubaki Takayuki), who reprised his role in Kamen Rider Decade by voiced his character in Kamen Rider × Kamen Rider W & Decade: Movie War 2010. As a child, he was portrayed by Takumi Kagawa (香川拓海, Kagawa Takumi). As Kamen Rider Blade, his suit actor was Seiji Takaiwa (高岩成二, Takaiwa Seiji), who has been the suit actor for the majority of the leading Heisei Kamen Riders (except Kuuga and Hibiki).

Rider No.

As the leading Rider protagonist of Kamen Rider Blade, Kazuma Kenzaki (Kamen Rider Blade) is labeled Kamen Rider #20 (仮面ライダー20号, Kamen Raidā Nijūgō) and Heisei Rider #5 (平成ライダー5号, Heisei Raidā Gogō). Quiz! Decade Countdown!!

Memes

Kazuma is the center of a Japanese meme dubbed "Ondul" (ｵﾝﾄﾞｩﾙ, "Ondul"), in which actor Takayuki Tsubaki's emotion-slurred speech, is treated as a separate language (the name comes from his line in the first episode, "Have you really betrayed us?!" (本当に裏切ったんですか!, Hontōni uragittan desu ka!), with "honto" ("really") coming out as "ondul", turning into Ondourur ragitta ndisukā! (ｵﾝﾄﾞｩﾙﾙﾗｷﾞｯﾀﾝﾃﾞｨｽｶｰ!, Ondourur ragitta ndisukā!)). This meme was named the "Ondul Language" (オンドゥル語, Onduru go) and has been referenced in other works, such as The Melancholy of Haruhi Suzumiya.
- The meme has been acknowledged within the Kamen Rider franchise, with Kazuma Kendate of Kamen Rider Decade mistaking "Chief" and "cheese". It is further referenced in Kamen Rider Climax Heroes, where "Have you really betrayed us?!" is Blade's special intro dialog with Garren, and in Kamen Rider: Battride War, where the quote is the name of one of the game's achievements.
- Memes surrounding the other main characters (Sakuya Tachibana, Hajime Aikawa and Mutsuki Kamijo) have since spawned among Japanese fans, and have been referenced in many parodies uploaded online.
In episode 3 once learning from Tachibana that their bodies are deteriorating from using the Rider System, a traumatized Kenzaki shouted "No way! There's no way that's true!" (嘘だ!嘘だそんなこと!, Uso da! Uso da sonna koto!). This scene is memorized by fans due to Tachibana's infamous "My body is falling apart!" quote came before that, including Kenzaki's over the top manner of shouting it.

Legend Rider Devices

Several Rider Cards allow Tsukasa Kadoya/Kamen Rider Decade to access the power of Blade.

KamenRide Card: Regained when Tsukasa shows Kazuma that even followers are important as leaders.Blade Blade Decade uses the card to assume the form of Blade's Ace Form. A KamenRide: Blade card is also possessed by Diend, which he uses to summon Blade. First used in the World of Agito to fight the Lords.

When Kamen Rider Decade is in his Complete Form, he uses the K-Touch to summon the Final Forms of the Nine Heisei Riders. After he presses the Rider's symbol, a card of that Rider's Final Form appears in a set of nine on Kamen Rider Decade's chest. The Blade King card summons Kamen Rider Blade King Form, armed with the King Rouzer. Using the Blade Final AttackRide card allows Decade to execute a Royal Straightflash-style attack alongside Blade King Form.

These cards allow Decade to perform any of their own attacks, Decade is also able to use any signature attacks of whatever Kamen Rider he has transformed into. The Blade Attack Ride Cards allow Decade as Blade to invoke the power of the Rouse Cards.

Metal: As Blade, Decade invokes the power of the Seven of Spades Rouse Card, Metal Trilobite, to enhance resilience to physical harm by transmuting his body into organic metal.
Mach: As Blade, Decade invokes the power of the Nine of Spades Rouse Card, Mach Jaguar, to enhance his speed and agility.

Notes

As acknowledged in the hero change battle between Kamen Rider Decade and Gokai Red in Super Hero Taisen, Blade's Spade motif makes him his series' equivalent of Spade Ace from Shotaro Ishinomori's second and last Sentai series J.A.K.Q. Dengekitai.
He shares the same surname as Makoto “Makopi” Kenzaki (Cure Sword) from Doki Doki! Pretty Cure as Kazuma & Makoto both share the same kanji spelling 剣崎 (Kenzaki, 剣崎). Fittingly, just like Makoto, they both share a spade motif, their series has the main motif of card suits, and has a sword themed identity (Blade, Sword).
The name "Blade" is a pun on the Minor Arcana version of the Spade cards: The Suit of Swords.
Every time Blade uses Tackle Boar, his attack is always evaded since it is too predictable. Ironically, the only time it worked was when it was used against him in the Hyper Battle Video.
The Kamen Rider Blade suit has showcased a few oddities over the years.
- The suit's midriff portion would at times appear to be made of cloth rather than the leather-like material the rest of the suit was made out of, while at other points it would appear to be uniformly made of the latter material.
- The face portion of the helmet would at times appear gold as opposed to silver, necessitating post-filming editing to appear consistent. According to Kamen Rider Zi-O producer Shinichiro Shirakura, this is the result of certain lighting conditions affecting the materials the faceplate was constructed from.
Although it was thought that Kenzaki's King Form is different in terms of looks compared to the intended form by BOARD developers, the A.R. Blade seemingly disproves that.
- The nature of K-Blade may differ between Rider worlds, but it could also be considered a result of cost-effective designs, production-wise. If the S.I.C. models were any indication, the original intent of the armor overhaul would possess Spade suit-shaped designs, with the King Rouzer intended to still possess a storage space for Rouse Cards.
Blade is the first primary rider and the third rider to be in the blue colored suit in basic (not by changing form) after G3 and Knight, and then followed by Gaim.
- Conversely, Blade is so far the only one of the primary Heisei Riders not to have a form dominantly associated with the color red, or a shade of red (counting Decade's magenta as being a shade of red).
Of the four suits, the Spade Suit Undeads are the only ones to have each member appear in the series in their unsealed forms.
Notably, Kenzaki is one of the few Kamen Riders to have defeated Tsukasa Kadoya/Kamen Rider Decade in combat. Even more impressively, he did so with little trouble, something that no other Kamen Rider was able to do in Kamen Rider Decade.

Before the broadcast of Kamen Rider Blade, there was a filmed scene which would have Kenzaki meeting his predecessor, Takumi Inui/Kamen Rider Faiz. Takumi would pass the baton on to Kazuma, before the two transform together. This scene was only seen by several members of the production team and was never released anywhere else until pictures of said scene were leaked onto a magazine.
- The concept of hand-offs would later become a tradition in the Super Sentai series, starting with Blade's Super Hero Time partner, Tokusou Sentai Dekaranger, with previous Red Rangers acknowledging their time as finished as they pass on the franchise to the next Red Ranger.
- The concept of Riders from different series meeting each other would later become an important plot point in the Movie War movies.
- Similarly, a succeeding Rider appearing in a special final episode acknowledges this concept. With the two-part special finale of Kamen Rider Wizard being the main example.
Kenzaki, and by extension Blade, is the second "Hybrid Rider" whose power originates from technology that harnesses supernatural forces. (The Rouse system). He was preceded by Ryuki and would later be followed by Den-O, Decade, and Gaim.
- He is, however, the only Rider aside from Kohtaro Minami/Kamen Rider Black (RX) that is all three types of Riders in one. (Mystical, Biological, Technological)
Along with Shinji Kido/Kamen Rider Ryuki, Kenzaki has never killed a sapient creature, as he only seals the Undeads instead of outright murdering them.
- In the Trial Series' cases, it can be argued that the Trial series are only programmed machines, rather than actual living creatures.
Since Kenzaki is the only one without a truly happy ending, he may well be the most tragic of all the main Kamen Riders.
- This is noted by some of the fans who questioned why someone as kind as Kenzaki had to suffer such a terrible fate at the end of his series.
- However, Kenzaki's actor Takayuki Tsubaki himself stated that Kenzaki did technically have a happy end, since he managed to achieve his goal of saving every person in the world, including his dear friends.
- This is somewhat paralleled by the non-canon novel as Kenzaki was clearly unhappy with the choice he made and seemingly regretted it.
  - Currently though, as of the events of Kamen Rider Zi-O, Kenzaki has regained his humanity and reunited with his friends. This means that he technically has indeed achieved a happy ending, just not in his own series.
Kenzaki is the first of the three Riders whose final form caused him to turn into the race he was fighting against, with the other two being Eiji Hino and Kouta Kazuraba.
Alongside Tachibana, Kenzaki is the only Kamen Rider in Kamen Rider Blade to defeat a Category King Undead in combat, excluding the events of Missing Ace.
- Even more impressive is the fact that Kenzaki not only defeated the Undead using just Ace Form, but that he did not use any Rouse cards other than Change Beetle.
The card Kenzaki uses to become Blade, the Spade Ace, is more properly known as the "Change Beetle" card. "Change Beetle" would eventually become the transformation announcement for Soji Tendo's Rider form.
Kenzaki Kazuma is one of 2 characters to have 2 A.R. World counterparts. The other being Wataru Kurenai.
The reason behind Kenzaki's high fusion coefficiency is never explained in the series. However, Noboru Shima notes that many Undead simply have an ingrained instinct to protect their own kind. Considering Kenzaki's strong will to protect people, it is likely he synchronized with this part of them.
The Blay Rouzer and King Rouzer differ in the Rouse announcements: Whereas the Blay Rouzer announces the cards' ability and the name of the attack formed after scanning a group of cards, the King Rouzer calls out the cards' place in the playing card deck, as well as the name of the playing card hand produced by the cards scanned.
- Both of them are also voiced by different voice actors.
