Hajime Shijo is the president of the BOARD Corporation who secretly uses the sealed Mantis Undead to assume the form of the legendary Kamen Rider Chalice. Because he is more interested in business ethnics, Hajime sees himself as the only thing keeping BOARD alive by offering his company's aid once paid by the government.

Furthermore, he conspires with Kamata by taking the other Rider Systems to begin a joint plan to take over the world by creating the Joker card from the DNA of all four Ace Undead. Being unable to get Kazuma to give him the Blay Buckle by normal means, Chalice makes his presence known during Decade and Blade's fights against the Paradoxa Undead and the other BOARD Riders, stripping Kazuma of his Blay Buckle before fighting Decade until Todoroki's sudden appearance.

But Hajime escapes with the Garren Buckle as well, later taking the Leangle Buckle with his identity exposed to Hishigata and Mutsuki whom he abducts and sacrifices to complete the Joker card. Assuming the form of the Joker, Hajime meets his end at the hands of Blade and Decade.

Super Hero Taisen

A Joker Undead is present as one of the Kaijin Generals of Dai-Shocker in Super Hero Taisen. Given the fact that Hajime Aikawa was one of the Support Riders that Kamen Rider Birth brought in Let's Go Kamen Riders, it is safe to assume that this Joker is Shijo.

Ace Form

Unlike the original Kamen Rider Chalice, the Chalice Rouzer that Hajime Shijo uses is a Rider System rather than bestowed upon him. 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.

Joker (Blade)


After combining all four Rider Buckles, thus the Artificial Joker Card was created allowing Shijo to transforms into Artificial Joker Undead and dominate the Earth with the aid of Paradoxa Undead. However, Decade and Blade was able to turn the tables by using the Blade Blade to terminate the artificial Undead once and for all.

Gear & Accessories

  • The Chalice Rouzer is a Rider System created for Shijo himself. The full extent of its power is unknown, but the Chalice Rouzer is capable of reproducing the DNA of sealed Undead and mimic their forms with frightening accuracy, as well as their respective powers and abilities. Further adding to its uniqueness, is that Rouze Cards are swiped on it, which became the template for the Rider System's Rouzer technology.
  • The Chalice Arrow is Chalice's weapon and Rouzer, and functions as a multipurpose weapon. Simply put, it is composed of a bow with its curved ends as sharp as blades. This weapon is capable of shooting projectiles, as well as engage opponents up close using the bladed ends of the bow. The bow can also fold up, turning the Rouzer into a brass knuckle for stronger punches. By inserting the Chalice Rouzer into the bow, the Arrow can serve as the Rouzer for Chalice, activating Rouze cards without turning Chalice into an Undead.

Behind the scenes


Hajime Shijo is portrayed by Ruo.


  • Unlike his counterpart, Aikawa, Shijo is a human who turned into an Undead and he is purely evil.
  • His given surname, Shijo means number four in Japanese as this is related to his Joker Card where it has all four suit symbols.
    • It may also have a similarity to Hajime Aikawa's name, also a reference to "the beginning of the end", since his name sounds much like the word for death.
      • This also happens to be a superstition rooted in Japanese culture, being considered an unlucky number; Shijo himself was unlucky enough to die in the hands of Decade and Blade.
        • But in terms of his fate, It could also reflect Decade's arrival to the World of Blade as well; note that upside down, Decade's helmet resembles a skull, as well as his duty as the destroyer of worlds, and also having turned many Riders into cards in Movie War 2010.
