List of Kamen Rider Blade characters

Kamen Rider Blade is a Japanese tokusatsu series that serves as the 14th installment in the Kamen Rider franchise and the fifth entry in the Heisei era.

Main characters

Kazuma Kenzaki

Kazuma Kenzaki is a kind-hearted BOARD operative who believes in fighting to protect humanity. He was chosen to use the Rider System 02 to seal the Undead as Kamen Rider Blade. While his Rider powers eventually end up turning him into a Joker over the course of the second half of the series, he uses this to force the Battle Fight into a stalemate and allow his friend Hajime to continue living among humans. During the events of Kamen Rider Zi-O, Kenzaki becomes a human again when Amane uses the powers of Another Blade on him. However, during the events of Kamen Rider Blade 20th Anniversary STAGE&TALK, the Destroyer turns him into a Joker again.
Utilizing the Rider System 02, which consists of the Change Beetle card and the Blay Buckle belt, Kenzaki can transform into Kamen Rider Blade. While transformed, he wields the Blay Rouzer sword and possesses a deck of 13 spade-themed Rouse Cards that allow him to channel the Category Spade Undeads' powers and augment himself to perform special attacks. He can also perform varying Lightning finishers via a combination of the Thunder Deer card and up to two other Rouse Cards. To seal the Undead, Kenzaki uses Proper Blank cards. His personal vehicle is the Blue Spader motorcycle.
Later in the series, Kenzaki acquires the Rouse Absorber bracelet, which he can use in conjunction with the Absorb Capricorn card and other special Rouse Cards to assume the following power-up forms:

Jack Form: Kenzaki's super form accessed from the Absorb Capricorn and Fusion Eagle cards that fuses him with the Eagle Undead to grant a pair of wings. In this form, the Blay Rouzer is enhanced into an extendable Empowered Type.
King Form: Kenzaki's final form accessed from the Absorb Capricorn and Evolution Caucasus cards that was only intended to fuse him with the Caucasus Undead, but his unusually high fusion rate causes him to instead fuse with all 13 Undead in the Category Spade suit, which ultimately accelerates his transformation into a Joker. In this form, he wields the King Rouzer broadsword, which allows him to perform the List of poker hands#Royal flush and List of poker hands#Four of a kind finishers on its own and the List of poker hands#Straight flush finisher with the Blay Rouzer.

Additionally, during the events of Kamen Sentai Gorider, Kenzaki becomes Ao-Rider, the blue-colored member of Kamen Sentai Gorider
Kazuma Kenzaki is portrayed by Takayuki Tsubaki.

Sakuya Tachibana

Sakuya Tachibana is a BOARD researcher turned field operative who was selected to use the Rider System 01 to seal the Undead as Kamen Rider Garren. Unlike Kenzaki, Tachibana fights to seal the Undead to stave off his death from cellular breakdown, which he blames on his superior Karasuma, and displays a rivalry with Kenzaki, who was chosen to provide backup for Tachibana. After learning from a Karasuma body double that his subconscious fears are causing his condition, Tachibana joins forces with Isaka in exchange for Schuld Kestner seaweed to cure himself despite it intensifying his aggression and slowly damaging his nervous system. When Isaka kills his girlfriend, Sayoko Fukasawa, Tachibana overcomes his fear and seals him. Following this, he goes on to take Mutsuki Kamijo under his wing and settle his differences with the Giraffa Undead.
As of the web-exclusive crossover series Kamen Rider Outsiders, Tachibana has become the president of BOARD.
Utilizing the Rider System 01, which consists of the Change Stag beetle card and the Garren Buckle belt, Tachibana can transform into Kamen Rider Garren. While transformed, he wields the Garren Rouzer handgun and possesses a deck of 13 diamond-themed Rouse Cards that allow him to channel the Category Diamond Undeads' powers and augment himself to perform special attacks. He can also perform varying Burning finishers via a combination of the Fire Firefly card and up to two other Rouse Cards. Like Kenzaki, Tachibana uses Proper Blank cards to seal the Undead. His personal vehicle is the Red Rhombus motorcycle.
Later in the series, Tachibana acquires his own Rouse Absorber, which he can use in conjunction with the Absorb Serpent card and other special Rouse Cards to assume the following power-up forms:

Jack Form: Tachibana's super form accessed from the Absorb Serpent and Fusion Peacock cards that fuses him with the Peacock Undead to grant three pairs of wings. In this form, the Garren Rouzer is enhanced into a bayonet-like Empowered Type.
King Form: Tachibana's final form accessed from the Absorb Serpent and Evolution Giraffa cards that unlike Kenzaki's version works as intended and only fuses him with the Giraffa Undead. As such, it does not carry the risk of transforming into a Joker, though it is still incredibly taxing on his body and can only be used for a short time. In this form, he wields a rifle version of the King Rouzer. This form first appears in the web-exclusive crossover series Kamen Rider Outsiders.

Sakuya Tachibana is portrayed by Kousei Amano.

Hajime Aikawa

The Joker, also known by his human alias of Hajime Aikawa, is a mysterious and infamous longhorn beetle-themed Undead whose victory in the Battle Fight results in the end of all life on Earth. After the Human Undead won the original Battle Fight, he willingly surrendered himself to Joker to help him hide his presence. When the Undead were released two years prior to the series, Joker re-sealed the Mantis and Human Undead. However, the Royal Club Undead knew of his use of the latter and mounted attempts on Joker's life, with the most recent leading to the death of photographer, Kurihara. Upon learning of the photographer's family, Joker took on the identity of freelance photographer "Hajime Aikawa" and vowed to protect them in atonement. Initially holding a low opinion of humanity, Hajime slowly comes to accept them due to his time with the young Amane Kurihara.
Over the course of the series, Hajime develops rivalries with Kazuma Kenzaki and Sakuya Tachibana, though he gradually warms up to them, eventually considering the former a dear friend of his. Once all of the other Undead are sealed, Hajime loses control of his Undead powers until Kenzaki sacrifices his humanity to force the current Battle Fight into a stalemate so Hajime can resume his human life. During the events of Kamen Rider Zi-O, Hajime becomes a true human when Amane uses the powers of Another Blade on him. However, during the events of Kamen Rider Blade 20th Anniversary STAGE&TALK, the Destroyer turns him back into the Joker.
In an alternate ending depicted in the film Kamen Rider Blade: Missing Ace, Kenzaki seals Hajime, though he eventually frees him four years later to help defeat the Albino Joker. Ultimately, Hajime sacrifices himself to do so, though his spirit continues to watch over Amane.
Unlike the BOARD-sanctioned Riders, Hajime utilizes the Chalice Rouzer belt to transform into sealed Undead via their corresponding Rouse Cards. As such, he can use either the Change Mantis card to transform into the Mantis Undead, which became known as Kamen Rider Chalice due to its resemblance to the Kamen Riders, or the Spirit card to transform into the Human Undead, which became his human form. As Kamen Rider Chalice, he wields the bladed Chalice Arrow bow, which can change from Blade Mode to Rousing Bow Mode by combining with the Chalice Rouzer's Rouzer Unit buckle, and possesses a deck of 13 heart-themed Rouse Cards that allow him to channel the Category Heart Undeads' powers and augment himself to perform special attacks. He can also perform varying Spinning finishers via a combination of the Tornado Hawk card and up to two other Rouse Cards. His personal vehicle is the Shadow Chaser motorcycle.
Using the Evolution Paradoxa card, Hajime can fuse himself with his entire card deck to transform into his final form; Kamen Rider Wild Chalice. While transformed, he wields the Wild Slasher kama, which can change from its two-piece Rousing Sickle Mode to its one-piece Rousing Bow Mode by combining with the Chalice Arrow. He can also fuse all 13 of his Rouse Cards into the Wild card card, which allows him to perform the Wild Cyclone finisher with the Wild Slasher in Rousing Bow Mode.
Hajime Aikawa is portrayed by Ryoji Morimoto.

Mutsuki Kamijo

Mutsuki Kamijo is a weak-willed high school student who was chosen by the improperly sealed Spider Undead to reluctantly utilize the Rider System 03 and become Kamen Rider Leangle. While under the monster's control, he battles the other Kamen Riders until the sealed Tiger and Tarantula Undead give him the strength to fight under his own power, overcome the Spider Undead, and seal it properly. Soon after, Mutsuki joins the other Riders in their fight against the remaining Undead.
Utilizing the Rider System 03, which consists of the Change Spider card and the Leangle Buckle belt, Mutsuki can transform into Kamen Rider Leangle. While transformed, he wields the Leangle Rouzer staff and possesses a deck of 13 club-themed Rouse Cards that allow him to channel the Category Club Undeads' powers and augment himself to perform special attacks. He can also perform varying Blizzard finishers via a combination of the Blizzard Polar bear card and up to two other Rouse Cards. His personal vehicle is the Green Clover motorcycle.
During the events of Kamen Rider Blade 20th Anniversary STAGE&TALK, Mutsuki acquires his own Rouse Absorber, which he can use in conjunction with the Absorb Tiger and Evolution Tarantula cards to assume his King Form. Like Tachibana's version, Mutsuki's does not carry the risk of transforming into a Joker, as it only fuses him with the Tarantula Undead, but it is highly taxing on his body. In this form, he wields a spear version of the King Rouzer.
