"Humagears, androids equipped with artificial intelligence, offer direct job support in our day and age. A young president of a technology company specializing in A.I. technology fights to protect the dreams of others!"
―Opening Narration

Episodes 1-16

Japan has entered a new era. Hiden Intelligence, the country's most thriving technology company that specializes in artificial intelligence (AI), has developed a way to utilize these A.I.s in a humanoid form, known as the Humagear. These virtually identical humanoid androids have become a staple in everyday life, to the general public as well as the private sectors. After his grandfather's death, a young but failing stage comedian named Aruto Hiden is chosen by his late grandfather to take his place as Hiden Intelligence's CEO. He initially refused, however, he became witness to several terrorist attacks orchestrated by, prompting the creation of an anti-A.I. military squad, A.I.M.S. to combat the chaos. Wanting to protect the people as well as his family's reputation, Aruto decides to become Kamen Rider Zero-One and plunges himself into an explosive war between him,, and A.I.M.S.

Episodes 17-29

With the threat now eliminated, it only sparked the tip of the iceberg as a new contender joins the battlefield, Gai Amatsu. As the CEO of ZAIA Enterprise, he wishes to show the world that the superiority of humanity reigns high over the Humagears and fights Aruto to prove himself right. With Gai opposing him as Kamen Rider Thouser, and the revival of The Ark and as well as learning the truth of their origins, Aruto has his work cut out for him as he faces opposing threats on multiple fronts.

Episodes 30-Present

Zaia Enterprise has succeeded in acquiring Hiden Intelligence, effectively overthrowing Aruto's position as CEO. Even though Aruto has returned to the bottom of the food chain, giving up is not in his blood as he must trek with Fuwa and form a new alliance with Jin if he ever hopes to stand a chance against Gai and fight his way back up by starting a small company of his own called HIDEN Manufacturing

Suit Actors


  • With "zero" in Japanese and "one" in Japanized-English, Zero-One can be read as Rei Wan (零 ワン) in Japanese, referencing the fact that he is the Kamen Rider of the Reiwa era.
    • The characters "zero" and "one" are known in tech, electronic and the mathematic world as Binary numbers, which is fitting for the series due to its theme of artificial intelligence.
  • Coincidentally the series' release date matches the name of the show/rider (September 1st, Zero-One/01).
  • This is the first series since Kamen Rider Kabuto to have five varies transformation item.
    • Different than Kabuto series, the transformation item also indicate the group side which the characters were sided on. 
Kuuga-ZeroOne Concept

From upper left to lower right, Leon, Lady, Rider 3-Changes, Mecha Rider

  • Being the first Reiwa series, the rider designs contain several elements taken from the discarded concepts of Heisei's first, Kamen Rider Kuuga. For example:
    • The main rider is based on insects (Kuuga and Zero-One), a second rider based on land creatures (Leon and Vulcan), and a third female rider (Lady and Valkyrie).
  • The opening credits use the same font as Kamen Rider Zi-O but only in the episodes where the opening song is not played at the beginning of the episode..
  • This series marks the first time since Hibiki where Seiji Takaiwa is not the suit actor of the main protagonist's Rider form. Instead, Takaiwa portrays Kamen Rider Horobi starting in episode 4, while Yuya Nawata took on the titular role of Zero-One.[10]
  • This is the first season since Kamen Rider Kuuga to not use the (vocal/instrumental) opening for the next episode preview. Instead, they used a standalone instrumental for the next episode preview.
  • Interestingly, the first episode of each of the three story arcs have I'm the President, and a Kamen Rider in their titles.
