List of Kamen Rider Blade Characters - Kamen Riders

Kamen Riders

• 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 (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. He would ultimately sacrifice his own human existence by mutating into the Navy Joker after excessive use of his Rider form's King Form transformation. This, to create a stalemate in the Battle Fight and save mankind, but more importantly, to allow Hajime—his friend & the Chalice Joker—to continue his life as a human.

• 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?). By the start of the series, Tachibana begins to suffer a form of cellular breakdown with only sealing the Undead slowing down the process. That, combined with his feelings towards Kenzaki being his backup when he can't manage it, Tachibana blames Karasuma for his condition. When he attempted to seal the Locust Undead before it attacked BOARD, Tachibana 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 Tachibana learns that it is his subconscious fear that is causing the breakdown. By then, Tachibana 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, Tachibana was unaware of the eventual damage it would do to his nervous system. Though his dear friend Sayoko Fukasawa warned him in vain, Tachibana shrugged it off until he learned that Isaka murdered Sayoko for meddling in his affairs, overcoming his fear while defeating the Peacock Undead and sealing him.

Later in the series, as his way of repenting for being maniplated by an Undead, Tachibana takes Mutsuki under his wing. 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 if only Hajime is the last Undead standing, Garren insists to believe 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 Kenzaki that he was saved because of him.

• Hajime Aikawa

Hajime Aikawa (相川 始, Aikawa Hajime?) is a mysterious man who is the Joker Undead, the most feared of the Undead as his victory in the Battle Fight would mark the end of all life on Earth. Unsealed around the time the other Undead were released, Joker battled The Mantis Undead and uses the sealed Category Ace of Hearts (Change Mantis) to become the wild card Kamen Rider Chalice (仮面ライダーカリス, Kamen Raidā Karisu?). He later seals the Human Undead, who willingly surrendered to him without resistance, using the card to assume human form. The effect of prolonged use of both of these cards to assume their forms resulted with both the Human Undead's compassion for life and the Mantis' Undead's fighting spirit collectively suppressing Chalice's natural destructive impulse as the Joker. However, many of the Royal Club Undead who knew his true identity made attempts to dispose of him. One such attempt by the Giraffa Undead ended with an innocent bystander witnessing the battle being mortally wounded by accident in the skirmish. The dying photographer handed him a photograph of his family and Joker decide to protect his family in which he did to atone for his death. The Joker took on the identity of freelance photographer Hajime Aikawa since then. Though he thought less of humans originally, Hajime's time in lives at Jacaranda Cafe with Kurihara's family warmed him up to humans and eventually, he wish for himself to be human instead of being the Joker.

Though he and Kenzaki disliked each other earlier, Hajime's growing humanity eventually warms up to Kenzaki, who became a dear friend of his, then Garren and later to a limited extent, Mutsuki as well. But 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 use the Undead against him. Even after managing to reseal them all, the Joker failed to regain control and goes on a rampage until he is provided with the Evolution Paradoxa, allowing Hajime to finally have full control of himself. However, this lasted until Giriffa Undead was sealed, with Hajime losing control and his impulse as Joker comes forth with the Stone of Sealing creating his army of DarkRoaches to eliminate all humans. In the end, Kenzaki is the only one to fight him head on, with Hajime pleading Kenzaki to defeat and seal him.

While in the series ends with Hajime allowed to live as a human thanks to Kenzaki sacrificing his humanity to put the Battle Fight in a stalemate, the movie provides an alternate ending to the fight that has him sealed by Blade. However, the actions of the Albino Joker four years later forced Kenzaki to have Leangle unseal Hajime to aid in protecting Amane as his true self and later as Chalice. In the end, Hajime sacrificed himself by switching places with Amane to save her and give the other Riders an advantage over their enemy. His spirit was later shown watching over Amane, the girl assured by Kenzaki that Hajime will always be there.

• Mutsuki Kamijo

Mutsuki Kamijo (上城 睦月, Kamijō Mutsuki?) is a weak-willed 17-year-old high-school kid was chosen by the improperly sealed Category Ace of Clubs (Change Spider/Spider Undead) to use the Rider System 03 and become Kamen Rider Leangle (仮面ライダーレンゲル, Kamen Raidā Rengeru?), though reluctantly at first. He gains a thirst for power as the Spider Undead takes over his mind, using him to attack the other Riders. But, later he is redeemed thanks to the sealed Tiger and Tarantula Undead giving Mutsuki the strength to force the Spider Undead out and the chance to fight on his own power, eventually allowing him to seal the Spider Undead properly and using the Rider System without any adverse effects, while psychologically properly completes him as a man capable of being a rider. Soon after, Mutsuki becomes a valuable ally to the other Kamen Riders. He is also the only Kamen Rider in the show that is based on an arachnid.
