"Our act puts an end to yours!"
―Hajime before battling the Titan Undead[src]
"Say that again...and I'll kill you!"
―Hajime's threat to Kenzaki questioning his Kamen Rider status, perhaps his infamous quote from the series[src]

Hajime Aikawa (相川 始 Aikawa Hajime) is Kamen Rider Chalice (仮面ライダーカリス Kamen Raidā Karisu, Masked Rider Chalice), a character from the tokusatsu TV series Kamen Rider Blade.


TV Series

He 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. 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 named Shin Kurihara a.k.a. Amane's father witnessing the battle being mortally wounded by accident in the skirmish. The dying photographer handed him a photograph of his family and Joker decides 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 living at Jacaranda Cafe with Kurihara's family warmed him up to humans and eventually, he wished 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 becomes 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. This allows him to even assume Wild Form, which he previously avoided to the best of his abilities, without losing control. This lasted until the Giraffa Undead was sealed, with Hajime losing control and his impulse as Joker bringing forth with the Stone of Sealing creating his army of Dark Roaches 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. However, Kenzaki himself mutates into the Joker through the excessive use of King Form transformation in order to save Hajime and made his victory null, continuing the fight, retracting all unleashed Dark Roaches and prolonging destruction indefinitely. This effectively renders them rivals by instinct and they can never see each other again, or they would be forced to fight to the death for dominance the next time they meet. Moments after the battle, Hajime lives with the Kurihara family and was allowed to keep his Spirit Card to maintain the human disguise.

Hajime Aikawa/Kamen Rider Chalice in Missing Ace.

The Missing Ace 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 was assured by Kenzaki that Hajime will always be there.

Kamen Rider Decade


Kamen Rider Chalice was one of the many Kamen Riders who fought in the Rider War against Decade and were all destroyed. They were presumably restored after the destruction (and subsequent revival) of Decade ended the Rider War and the worlds were restored.

But later, Hajime, alongside Mutsuki, Tachibana, and Kenzaki, aided the riders against Shocker after they despise how Shocker acts and also had themselves free from brainwashing immediately thanks to Go and Yuto, including a now redeemed Kyoichiro for defeating them earlier, even after Takeshi Hongo alongside Hayato Ichimonji broke free from Rider Robo.

Ace Form

Ace Form

―Transformation announcement[src]
  • Height: 204cm
  • Weight: 109kg
  • Ability perimeters
    • Punching Power: 3.2t, 320 AP
    • Kicking Power: 5.2t, 520 AP
    • Maximum Jump Height: 45m
    • Maximum Running Speed: 100m/4.8

Unlike the B.O.A.R.D Riders, Chalice is not a Kamen Rider transformation produced by a Rider System. Chalice is in fact the name of the legendary Mantis Undead of the A: "Change Mantis". The Joker, using the Rouze Card of this sealed Undead, mimics the form, attributes and power of the Mantis Undead via the Chalice Rouzer. Though Chalice favors agility, this "Undead Rider" is basically superior to the B.O.A.R.D Riders in every respect, making him a lethal adversary to either side: Undead or Rider.

Wild Chalice

  • Height: 204cm
  • Weight: 109kg
  • Ability perimeters
    • Punching Power: 4.2t, 420 AP
    • Kicking Power: 6.2t, 620 AP
    • Maximum Jump Height: 60m
    • Maximum Running Speed: 100m/4.5

Wild Chalice (ウアイルツドカリス Uairuddo Karisu) is the ultimate form of Chalice, which merges the power of the K: "Evolution Paradoxa" with A: "Change Mantis" to unify the powers of the other Rouse Cards of the Heart Suit. Outside of its combat practicality, Wild Chalice serves an even more vital purpose to Chalice. Thanks to the additional power of the Paradoxa, Wild Chalice can suppress the power of the Joker and effectively subdue its influence. To that effect, Wild Chalice becomes an extension of the Joker's "Trump" effect and can harness the powers of all Rouze Cards in the form of the "Wild Card". Interestingly, Wild Chalice has a nearly identical color scheme to Garren's, having a crimson base and green visor.

When Hajime's Ace card was taken by the Eagle Undead, he uses the Float Dragonfly card to assume the Dragonfly Undead. He later gave his Float Dragonfly card to Kenzaki to defeat the Eagle Undead. Kenzaki did and gave back his Ace of Hearts card.

Wolf Undead

When Hajime lost all of his cards including Ace, Kenzaki gave the Fusion Wolf card to him to assume the Wolf Undead form to battle Mutsuki. This card was shown to be the Wolf Undead also known as Jack Form without the Rouze Absorber.

Joker Undead

Joker Undead

  • Height: 219 cm
  • Weight: 116 kg

Joker is the true identity of Hajime Aikawa, and the embodiment of Death in the Battle Royale. Joker technically "wins" the Battle Royale at the end of the series when Giraffa is sealed, causing the Sealing Slab to produce an army of DarkRoaches to exterminate all life, as well as having Hajime lose control of his power, and in order to do regain his, Hajime must find Kenzaki and force him to fight Hajime to put an end to the DarkRoaches' reign by the Sealing Slab. But Kenzaki sacrifices his humanity, becoming a Joker himself, and allows Hajime to continue living as a human not be sealed, with the Spirit Human keeping him in line.

In Missing Ace, he was initially sealed by Blade and remained there in the four-year timeskip. After being unsealed by Leangle to protect Amane from Glaive's assault, Hajime chose to sacrifice himself in order to make Jashin 14 (then under the control of the fully revealed Albino Joker) vulnerable for the others to attack.

Behind the scenes


Hajime Aikawa is portrayed by Ryōji Morimoto (森本 亮治 Morimoto Ryōji). As Kamen Rider Chalice, his suit actor was Makoto Ito (伊藤 慎 Itō Makoto).


  • As acknowledged in the hero change battle between Kamen Rider Decade and Gokai Red in Super Hero TaisenIcon-crosswiki, the Riders of Kamen Rider Blade share their card motifs with the heroesIcon-crosswiki from Shotaro Ishinomori's second and last Sentai series J.A.K.Q. DengekitaiIcon-crosswiki. Chalice's Hearts motif would make him Blade's equivalent of Heart QueenIcon-crosswiki. His true identity as the Joker would also make him the equivalent of Big OneIcon-crosswiki.
  • The name "Chalice" comes from the Minor Arcana version of the Suit of Hearts: the Suit of Cups which symbolize the emotion and love that Hajime acquired over the series.
  • He is the only Rider in Blade that doesn't need a Rouze Absorber to use an upgrade form, as well as the only Rider who does not need AP to use Rouze Cards, although the AP counter and its usage is never a major point in the series.
  • While Garren is the second rider to appear in the series, Chalice is the true Secondary Rider in the series due to intense rivalry with Blade.
    • Thus, he is the first non-human Secondary Rider.
    • He is also the first Secondary Rider to also be the final villain.
    • He is the second Secondary Rider after Ren Akiyama to have a more fortunate ending than the Primary Rider, at the cost of the Primary Rider's own well-being (Shinji Kido is killed, leaving Ren to fight the final villain in his place; while Kazuma Kenzaki sacrifices his humanity to allow Hajime to continue living in the human society.).
  • Hajime's name, which means "Beginning", is both ironic and symbolic: It is ironic, because he is supposed to bring about the end of the world, but it is also symbolic since his appearance as Joker symbolizes the beginning of the Battle Fight and the beginning of the end of the world.
  • Hajime is the second Rider to became the Final Boss of a series, after Kamen Rider Odin and later followed by Gryllus Worm (the fourth TheBee), Lord Baron, and Kamen Rider Amazon Alpha. He is also the first one to have a major role in the series, with Hajime being considered the Secondary Rider of Blade despite being the third Rider to appear in the series.
