Blade Joker!? 2019

"Can fate not be denied?!"
―Kazuma screamed on Hajime, struggling to hold his undead's instinct[src]

During Hajime's battle against Sougo, Kazuma Kenzaki had reappeared in front of them. Angrily asking Hajime why he had used his Undead powers, Kazuma transformed into Kamen Rider Blade. In a seemingly uncontrollable fit of rage, Kazuma viciously attacked Chalice, despite his pleas to stop. The battle was evenly matched, with both sides showing no signs of giving up.

2019: Trinity Has Begun!

While Kazuma and Hajime were busy fighting each other, Zi-O and Another Blade resumed their battle. Just when Kazuma used his Lightning Sonic, Another Blade was knocked towards Hajime's side. Noticing this, Hajime attempted to shield her with his body, however, Kazuma's attack proved too powerful to completely block, causing Another Blade to revert back into Amane. Hajime called out to her in concern, causing Kazuma to freeze in shock. Once he was sure Amane was uninjured, Hajime then escaped from Kazuma, with Amane chasing after him.

With the battle concluded, Kazuma went to 9 5 DO with Sougo and his friends. There, Kazuma explained the situation, before telling them that the matter did not concern anyone else. In a huff, Kazuma then rushed out the shop to find Hajime.

Finding Hajime with Amane, Kazuma forced the former to battle him again. In the middle of their battle though, Amane cried out for them to stop fighting each other. White Woz then reappeared before Amane, forcefully turning her into Another Blade. Another Blade then went berserk, attacking both Blade and Chalice. The two tried to turn Amane back to normal, but were unsuccessful.

Once knocking back Kazuma and Hajime into their human forms, Another Blade absorbed the essence of the Joker Undead from them into herself, thus technically becoming the victor of the Battle Fight. Now wounded and bleeding red blood, Kazuma and Hajime were forced to watch as Another Blade summoned the monolith, which started producing an army of dark colored Joker Undeads while the skies darkened. Luckily, Geiz, Black Woz, and Sougo intervened in time, awakening the new power of Zi-OTrinity which defeated the powered up Another Blade. They reverted Another Blade back into Amane and destroyed the Another Blade Ridewatch, while the Blade and Chalice Ridewatches also fell from her. The monolith seemingly was reduced to dust as Another Blade was destroyed. The battle having ended, Kazuma watched from afar as Hajime and Amane reconciled with each other. Sougo then came up to him, trying to hand him the Blade Ridewatch and the Chalice Ridewatch. Kazuma allows Sougo to keep the watches, feeling that he would need it more than them, and noting that thanks to them, the power of the Jokers had been sealed. Telling Sougo that he and Hajime can now continue to live on with their lives, Kazuma goes up towards his old friends, while Sougo and Geiz watch with a smile. 2019: Trinity Has Begun!

Whether Kazuma continued to enjoy his true human life or was once again transformed into Undead following Kamen Rider Ohma Zi-O's timeline reset is currently unknown. 2019: Apocalypse


By 2019, Kazuma has changed greatly for the worse. Due to Hajime Aikawa/Kamen Rider Chalice's actions, Kazuma 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, Kazuma seemed focused solely on defeating Hajime, despite the latter's pleas to stop. White Woz's note only worsened Kazuma's predicament, allowing him to track Hajime's location and force his former friend to fight. Despite this aggressiveness, Kazuma was initially shown to be regretful at having to fight against Hajime, as well as somewhat showing concern with Amane's predicament.

Once his transformation 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.

Ace Form (エースフォーム Ēsu Fōmu) is the default transformation of Rider System-02. The transformation harnesses the Beetle Undead's DNA cultured from the ♠A: Change Beetle Rouse 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 its ability to modify its capabilities with Rouse Cards.

Appearances: Zi-O Episode 29-30

Different Blade ZIOEp29.jpg

  • The color of Blade's discolored helmet (previously seen in Kamen Sentai Gorider) was adjusted in the teaser trailer to make its appearance look more similar to the original TV series quality.
    • Producer Shinichiro Shirakura explained that due to the way Blade's helmet was made, its colors change uncontrollably under various lighting conditions.[4]
