This article is about a/an rider in Kamen Rider Blade.

"Tachibana! Why are you watching? Tachibana...have you really betrayed us?!"
―Kenzaki's infamous quote, which later became a meme[src]

"I will fight fate...and win."
―Kenzaki after turning into the second Joker[src]

Kazuma Kenzaki (剣崎 一真 Kenzaki Kazuma) 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 Kamen Raidā Bureido). He has a good heart and believes in fighting to protect humanity.


Kazuma Kenzaki is a friendly, cheerful man. Partly due to his traumatic past, Kenzaki had a somewhat awkward side at first, struggling to befriend others. Furthermore, his tendency to naively trust others had been manipulated a number of times in the past, something with which Kenzaki himself felt frustrated with. Despite all this, Kenzaki 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 Kenzaki to fight against all odds.

Like many people near his age, Kenzaki initially had difficulty controlling his emotions, easily becoming distraught when dealing with a problem. The guilt Kenzaki felt for his inability to save his parents has also 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, Kenzaki matured greatly, even becoming a sort of mentor for Mutsuki Kamijo/Kamen Rider Leangle.

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

In Kamen Rider Decade though, Kenzaki had a drastic personality change as he went from kindhearted to cold and cynical. This is noted by official material to have been the result of turning into a Joker Undead and having to part 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 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 Kenzaki as an Undead. This implies that Kenzaki's resolve to help others had never wavered even after several decades had passed since sacrificing his humanity.

The Kenzaki that appeared in Kamen Sentai Goraider is shown to be an ally of justice, helping Emu Hojo/Kamen Rider Ex-Aid and the four deceased rider stop Kuroto Dan from reviving himself and taking over the world with Bugsters. Though fighting as an ally of justice, Kenzaki stopped Emu from preventing the sacrifice of the four deceased riders, as he felt it to be necessary to foil Kuroto's plans. Like in Kamen Rider Decade though, Kenzaki only did what he felt was right.

Unlike previous guest appearances, in the Drama CD: Kamen Rider Blade -The Whereabout of Trump, Kenzaki is still mostly the same as he was ten years ago. Still a kind and cheerful man, Kenzaki continues to wander around the world, helping those in need. While managing to retain his sense of self, Kenzaki has worries of losing control over his Undead instincts, which makes him not stay in one place for too long. Despite the troubles he faces from being an Undead though, Kenzaki continues to fight against destiny, confident that he will win.

In a possible future three hundred years later though, as depicted in the Kamen Rider Blade novel, Kenzaki's cynicism has overridden him. Having lived for so long through countless wars and battles without anyone to rely on, this Kenzaki became hopeless and defeated, often trying to find ways to kill himself and failing every time due to becoming the Joker Undead. This Kenzaki 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, Kenzaki become an amnesiac due to the manipulations by the Stone of Sealing, helping him fight again as a Kamen Rider. Yet as time passed by, Kenzaki slowly regained his memories and began losing his sanity once more. Before the final fight, the Stone of Sealing used Kenzaki'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 Kenzaki 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, Kenzaki no longer felt burdened as the second Joker Undead, as he was now freed from his Undead instincts.

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 (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--nowhere 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. Having sworn to fight against destiny and win, Kenzaki continued to live on with his life.

Missing Ace

Kazuma Kenzaki/Kamen Rider Blade in 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 defeated it and the Albino Joker in it with King Form.

Kamen Rider Decade

Main article: Kazuma Kenzaki (A.R. World)

About 5 years later, Kazuma Kenzaki appears as one of the nine Heisei Riders in Kamen Rider Decade then battles Tsukasa after Wataru told the latter that destroying the nine Heisei Riders was supposed to be his true goal, but he had failed to do that, and for that reason all worlds were headed to destruction.

This man has been identified in official written material as both the original Kazuma Kenzaki changed by his lonely life after the finale of Blade, or a A.R Kazuma Kenzaki from a parallel world[1].

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.

Final Chapter

In Decade: Final Chapter, Kenzaki in his regular Ace Form 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 voluntarily lets himself be 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.

Super Hero Taisen GP: Kamen Rider 3Icon-crosswiki


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 Tachibana during their infiltration to Shocker's base. However, it was revealed to be a lie as Tachibana was already an evil rider alongside Kenzaki. But soon Kenzaki alongside Tachibana, 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 TridoronIcon-crosswiki. 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.

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".

Faker Blade

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 afterwards, it can be assumed he left CR right after returning to the real world.

As Blade, Kenzaki 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 Common Blanks to seal the Undead. Having a strong fusion ratio with the Undeads of the Spade category, Kenzaki is able to bring forth each Undeads' true powers, to the point of managing to fuse with all thirteen simultaneously as Blade King Form.

In the final episode of Kamen Rider Blade, Kenzaki mutated into a Joker Undead 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.

Ace Form (エースフォーム Esu Fōmu) is the default transformation of Rider System-02. This transformation harnesses the DNA of the Beetle Undead cultured from the A: Change Beetle Rouze Card and, via the Blay Buckle, initiates a fusion with Kazuma Kenzaki into Kamen Rider Blade. This Rider Form has no distinguishing capabilities or attributes apart from the other Riders except its melee-oriented design and the ability he acquires from his signature Rouze Card deck. Despite this form's initial combat perimeters being lower than Chalice and Leangle, Kenzaki's compatibility, ingenuity and skill as a Kamen Rider more than compensates. This helped him overcome formidable foes including the Caucasus Undead--a King category Undead--without having access to his other Rouze Cards. In fact, in Missing Ace, Kenzaki even managed to defeat the Joker Undead in Ace form alone, further proving his skill.

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 Rouze Cards (in this case, the Jack: "Fusion Eagle") via the Rouze Absorber. Initiating Blade's Jack Form transmogrifies the Rider Armor with the attributes and characteristics of the Eagle Undead DNA with the J's "FUSION JACK" effect, effectively enhancing Blade's natural combat capacities. Blade's Jack Form imparts a number of enhancements; the first being the enhancement of the Blay Rouzer through a blade extension.

Outside of this cosmetic appendage, the Blay Rouzer essentially functions the same. The second advancement is the addition of reinforced golden-armor plating which increase resilience to impact damage. But the most drastic modification is the inclusion of wings, which enables flight for the Rider.

King Form

Ability Parameters

  • Punching Power: 4.5t (450 AP)
  • Kicking Power: 7.0t (700 AP)

  • Maximum Running Speed: 100m per 6.6 seconds

King Form (キングフォーム Kingu Fōmu) is the ultimate combat extension of the Rider System, which only Blade can obtain. Using the Rouze Absorber, this transformation is initiated using the K's "EVOLUTION KING" effect in conjunction with the Q's "ABSORB QUEEN" effect.

When transforming into King Form, Kenzaki's Spade Category cards will place themselves on his body to form armor. The King Form addresses many issues with Blade's combat capabilities, such as its defensive capacities, with a complete armor overhaul. This new heavy armored design is gold-plated and is increasing resilient to damage, but at the sacrifice of agility. Though King Form lacks agility, theoretically the usage of the Mach Jaguar, Time Scarab or Fusion Jack cards would more than make up for this flaw. The King Rouzer does not have a card storage like the Blay Rouzer. Instead, Kenzaki can automatically use his Rouze cards without scanning them. Moreover, it has been shown that Blade King Form is able to use both the Blay Rouzer and King Rouzer at once, usually as a form of dual wielding.

In Kamen Rider Wizard, Kenzaki has shown the ability to use a Rider Kick in this form, doing so without summoning any Rouze cards from his armor.

Undoubtedly, this is Kenzaki's strongest form as Kamen Rider Blade, overwhelming the likes of the Joker Undead, Kerberos Undead, a weakened Jashin Fourteen, and even Kamen Rider Decade himself.

Nevertheless, with all these improvements, Blade's King Form suffers from one glaring flaw: Kazuma Kenzaki. Initial specs intended only for the Blade Rider System to extend its combat capacities with the K: "Evolution Caucasus", but due to Kenzaki's unusually high fusion co-efficiency, the system exceeded its perimeters and exposed a disastrous glitch in the overall Rider System.

In the case of individuals like Kenzaki, activating the King Form extension initiates the fusion of, not just one, but the DNA of ALL 13 sealed Undead associated with a particular card-suit. With extended activity in this form, the subject's fusion co-efficiency would raise exponentially, ultimately mutating the human being into a Joker-type Undead.

To that end, use on Kenzaki's part was strictly cautioned and advised only as a last resort. This is currently no longer a problem since Kenzaki became an Undead after several uses. Being that he was originally a human though, Kenzaki still retains his sense of self and does not succumb to his Undead instincts.

"Final Form Ride: B-B-Blade!"
―Transformation announcement[src]

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, Movie War 2010

Beltless Leangle Episode 16

Leangle Ace Form

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 Kenzaki as seen in Day After Tomorrow.

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 Darkroaches, 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 Rouze 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 himself from near-death experiences.
  • 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 Rouze Card to obtain said Undead's form and powers.
  • Danger Intuition: During his half transformation into Undead around the series, Kenzaki seemed to develop a symbiosis with the real 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


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!!


Kazuma is the center of a Japanese meme dubbed "Ondul" (オンドゥル), 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 uragitta ndesu ka!), with "honto" ("really") coming out as "ondul", turning into Ondourur ragitta ndisukā! (オンドゥルルラギッタンディスカー!)). 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.

King of Poker Blade Gashat

Blade Rider Gashat

  • King of Poker Blade Gashat (キングオブポーカーブレイド Kingu obu Pōkā Bureido): Based on Kamen Rider Blade.

  • Blade Ridewatch (ブレイドライドウォッチ Bureido Raido Wotchi): Based on Kamen Rider Blade, this Ridewatch provides access to the BladeArmor used by Zi-O. Dated 2004 AD.[2]


  • As acknowledged in the hero change battle between Kamen Rider Decade and Gokai Red in Super Hero TaisenIcon-crosswiki, Blade's Spade motif makes him his series' equivalent of Spade AceIcon-crosswiki from Shotaro Ishinomori's second and last Sentai series J.A.K.Q. DengekitaiIcon-crosswiki.
  • 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.
  • 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, but the idea of the armor itself holding the cards as opposed to the weapon could apply to the other hypothetical King Forms.
  • Blade is the first primary rider and the third rider to be in 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.
Faiz and Blade Passing The Torch

Passing the torch.

  • 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-offsIcon-crosswiki would later become a tradition in the Super SentaiIcon-crosswiki series, starting with Blade's Super Hero TimeIcon-crosswiki partner, Tokusou Sentai DekarangerIcon-crosswiki, 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", gaining his powers through mystical means which also alter his body (The Undead) but requiring technology to access it (The Rouze system). He was preceded by Ryuki would later be followed by Den-O, Decade, and Gaim.
    • He is, however, the only Rider aside from Minami Kotaro/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 true happy ending, he may well be the most tragic of all the main Kamen Riders.
    • This is noted by some of the fans who question on 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's end is, in a sense, a happy end for him.
    • This is somewhat paralleled by the non-canon novel as Kenzaki was clearly unhappy with the choice he made and seemingly regretted it.
  • 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.
  • 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 Souji Tendou's Rider form.
  • 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 Rouze 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.
