List of Kamen Rider Blade characters

This is a list of characters from the Japanese tokusatsu series Kamen Rider Blade (仮面ライダーブレイド, Kamen Raidā Bureido).

BOARD[]

Short for the "Board Of Archaeological Research Department", BOARD uncovered the seal Undead Cards and developed the first two Rider Systems. In Super Hero Taisen GP ending, the organization becomes one of the sponsors along with Tachibana Racing Club for the former Kamen Rider 3 of altered timeline, Kyoichiro Kuroi.

Kazuma Kenzaki[]

Kazuma Kenzaki (剣崎一真, Kenzaki Kazuma) 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. He has a good heart and believes in fighting to protect humanity. He would ultimately sacrifice his own human existence by mutating into the second Joker after excessive use of his Rider form's King Form transformation. This forces a stalemate in the Battle Fight while there is more than one Undead, keeping mankind safe while allowing his friend Hajime, the original Joker, to continue living among humans. Kazuma makes return appearances in Kamen Rider Decade and Kamen Rider Zi-O; the latter of which saw his humanity restored.

As the user of Rider System-02, developed by BOARD to enable a human to augment themselves with Undead DNA via the Rouse Cards, Kazuma uses the Blay Buckle (ブレイバックル, Burei Bakkuru) belt in conjunction with the Change Beetle Rouse Card to become Blade. In his default form, Blade uses the Blay Rouzer (ブレイラウザー, Burei Rauzā) sword as both a weapon and a storage unit for Rouse Cards, including Proper Blanks. The Blay Rouzer's built-in 'rouzing' technology allows Blade to use an Undead's power in his attacks, using a combination of cards to execute a finishing attack.

Kazuma later receives the Rouze Absorber (ラウズアブゾーバー, Rauzu Abuszōbā), a brace-like supplementary Rouse device developed by Kei Karasuma to bolster his capabilities by harnessing the Royal Club Undead. Using the Absorb Capricorn as a catalyst, Kazuma uses the Fusion Eagle card to assume Jack Form (ジャックフォーム, Jakku Fōmu) with flight ability and the Blay Rouzer enhanced. After acquiring the Evolution Caucasus card, Kazuma gains the ability to assume King Form (キングフォーム, Kingu Fōmu) with the King Rouzer (キングラウザー, Kingu Rauzā) broadsword. While assumed to only absorb the DNA of the Caucasus Undead, Kazuma's Fusion Ratio was potent enough to assimilate his entire deck. With extended activity in this form, the subject's fusion coefficiency would raise exponentially, ultimately mutating the human being into a Joker-type Undead. To that end, use on Kazuma's part, was strictly cautioned and advised only as a last resort.

Kazuma Kenzaki is portrayed by Takayuki Tsubaki (椿隆之, Tsubaki Takayuki).

Sakuya Tachibana[]

Sakuya Tachibana (橘朔也, Tachibana Sakuya) was originally a researcher of BOARD's Humanity Foundation who graduated from the Sazahaibu University and was selected to be the user of Rider System 01, using the sealed Category Ace of Diamond (Change Stag) to become Kamen Rider Garren (仮面ライダーギャレン, Kamen Raidā Gyaren). From the beginning of the series, Sakuya begins to suffer a form of cellular breakdown, and only by sealing the Undead did the process slow down. Sakuya blames Karasuma for his condition, and the fact that Kazuma was appointed as his backup rider in case he could not cope on his own did not improve his relationship with Karasuma. When he attempted to seal the Locust Undead before it attacked BOARD, Sakuya is forced to abduct Karasuma for answers prior to him going into a coma. However, it is only revealed later that the "Karasuma" he safeguarded was only a decoy as Sakuya learns that it is actually his subconscious fear that is causing the breakdown.

Sakuya encounters Isaka, the Peacock Undead, who recruits him by removing his fears with exposure to Schuld Kestner seaweed, an extinct plant that intensifies the aggressive nature of the subject. Though he became more aggressive and worked under Isaka for more of the seaweed, Sakuya was unaware of the eventual damage it would do to his nervous system. Though his dear friend Sayoko Fukasawa tries to warn him, Sakuya does not listen until he learns that Isaka murdered Sayoko for meddling in his affairs. Sakuya overcomes his fear while defeating the Peacock Undead and sealing him.

Later in the series, as restitution for being manipulated by an Undead, Sakuya takes Mutsuki under his wing, attempting to help him stay in control of the Spider Undead. During the final few episodes, Kamen Rider Garren came face to face with the Giraffa Undead and battled it out with him. Despite the Undead warning him the consequences of Hajime being the last Undead standing, thus making him champion of the Battle Fight, Garren insists on believing in his friend before the two fall off a cliff. The battle ended with Garren nowhere to be found and the King Undead sealed leaving the Joker as the winner. He is found upon the arrival of the Chief telling Kazuma that he was saved because of him.

As the user of Rider System-01, the prototype of the Rider Sistem-02, Sakuya uses the Garren Buckle (ギャレンバックル, Gyaren Bakkuru) belt in conjunction with the Change Stag Rouse Card to become Garren. In his default form, Garren uses the Garren Rouzer (ギャレンラウザー, Gyaren Rauzā) handgun as both a weapon and a storage unit for Rouse Cards, including Proper Blanks. The Garren Rouzer's built-in 'rouzing' technology allows Garren to use an Undead's power in his attacks, using a combination of cards to execute a finishing attack. Sakuya later receives his own Rouze Absorber from Kei Karasuma to bolster his capabilities by harnessing the Royal Club Undead. Using the Absorb Serpent card as a catalyst, Kazuma uses the Fusion Peacock card to assume Jack Form (ジャックフォーム, Jakku Fōmu) with flight ability and the Garren Rouzer enhanced

Joker later seals the previous Battle Fight winner known as Human Undead, who willingly surrendered to provide him human form to hide his presence. But Royal Club Undead like the Griffa Undead knew of this and attempted to seal him, with a photographer named Kurihara mortally wounded by accident in the skirmish. The dying photographer handed him a photograph of his family and Joker decided to protect his family in order to atone for his death, assuming the identity of freelance photographer Hajime Aikawa. Though he thought less of humans originally, Hajime's time at the Jacaranda Cafe with Kurihara's daughter Amane's helped him accept humanity to the point of wished he was truly human.

Though he and Kazuma disliked each other earlier, Hajime's growing humanity eventually warms up to Kazuma, who became a dear friend of his, then Garren and later to a limited extent, Mutsuki as well. However, when the Caucasus Undead takes most of his cards, the sealed Mantis Undead among them, it causes Hajime to regress back into the Joker after attempting to resist until Leangle unseals Hajime's cards and uses the Undead against him. Even after managing to reseal them all, the Joker aspect regained control and goes on a rampage until he is provided with the Evolution Paradoxa, allowing Hajime to regain full control of himself. This lasted until the Giriffa Undead was sealed, leaving the Joker the final victor of the Battle Fight. Hajime loses control once more and his impulse as Joker comes forth with the Stone of Sealing creating his army of DarkRoaches to eliminate all life. In the end, Kazuma is the only one to fight him head on, with Hajime pleading Kazuma to defeat and seal him.

Titan (ティターン, Titān) is an Undead that Tennoji created by merging the Scorpion and Chameleon Undead into one body with access to the former's poison and the latter's cloaking/disguise abilities with two buckles on its belt. Titan is deployed to turn the Kamen Riders on each other before they trick the Undead into revealing itself and sealed it back into two cards.

Kerberos[]

Kerberos (ケルベロス, Keruberosu) is an Undead that Tennoji made from the DNA of all 53 Undead to surpass the Joker in power, created as the fifth Ace that Tennoji intended to be the victor of the Battle Fight he set up. But Keroberos was beyond Tennoji's control, killing his entire staff upon being born from the Stone of Sealing. The Undead succeeded in absorbing the decks of Chalice and Leangle, along with Jack and Queen cards of Garren. Kerberos even overpowered Blade King Form at first, but was defeated by Royal Straight Flush with Tennoji using the Change Keroberos on herself to become Keroberos II before Kanai takes it. While the card is lost in the series finale, Change Keroberos was recovered and used by Kamen Rider Glaive in the alternate events of Missing Ace, with two copies of the card used in creating Riders Lance and Larc.

Kerberos is voiced by Katsumi Shiono.

Darkroaches[]

The Darkroaches (ダークローチ, Dākurōchi) are cockroach-like Undead grunts that are extensions of the Stone of Sealing which manifest once Hajime is the sole remaining Undead in the Battle Fight with their only purpose is to wipe out all life on Earth, able to respawn from the monolith after being destroyed. Once Kazuma became the second Joker Undead, the Darkroaches vanished since Battle Fight was put into stalemate. The Darkroaches resurface in 2019 during the events of Kamen Ride Zi-O when Amane becomes the world's only Joker after extracting the Undead essence from Kazuma and Hajime into herself, only to be permanently destroyed once the Joker essence is completely eradicated.
