Kamen Rider Zero-One (仮面ライダーゼロワン Kamen Raidā Zerowan) is a Japanese tokusatsu drama in Toei Company's Kamen Rider Series. It is the first series to debut during the Reiwa period and the thirtieth overall. The series premiered on September 1, 2019[3], joining Kishiryu Sentai RyusoulgerIcon-crosswiki.png in the Super Hero Time line-up after the finale of Kamen Rider Zi-O. After Ryusoulger concluded on March 1, 2020, the series was joined in the Super Hero Time lineup with Mashin Sentai KiramagerIcon-crosswiki.png on March 8, 2020.[4] After Kamen Rider Zero-One concluded on August 30, 2020, Kirameiger currently airs alongside Kamen Rider Saber in the Super Hero Time block.

The catchphrase for the series is "There's only one strongest company president in the world! And It's me! (世界最強の社長はただひとり!オレだ! Sekai saikyō no shachō wa tada hitori! Ore da!) [5]


Development for the show had begun during the summer of 2018.[6] Producer Takahito Omori had visited several technological institutes and spoke with many professors and experts on the topic of artificial intelligence. On April 19, 2019, Toei Company filed and confirmed the trademark for Kamen Rider Zero-One.[7]

Yuya Takahashi was confirmed to be the head writer for the show, and submitted the completed scripts for Episodes 1 and 2 on May 1, 2019. Filming began in mid-June 2019, and the cast was introduced through a scheduled press conference in July. The series premiered on September 1, 2019.

Impact of the COVID-19 pandemic

As a result of the ongoing COVID-19 pandemic, filming schedules were altered and broadcasting of new episodes was delayed following the airing of Super Hero Time on May 10, 2020, which included Episode 35 of Zero-One and Episode 10 of Mashin Sentai KiramagerIcon-crosswiki.png. Ultimately, the fate of Kamen Rider Zero-One: The Movie's release, which was originally scheduled to premiere in July, was left unclear.

With the show on hiatus, resulting in a reduced episode count of 45 from the originally planned 49, the production team had to make script changes from Episode 39 onwards.[8]

  • The appearance of Kamen Rider Ark-Zero and Williamson Yotagaki were kept intact from the original plans. Ark-Zero was introduced much earlier than anticipated, appearing in the President Special miniseries.
  • Further writing were temporarily ceased, only having written up to Episodes 38 & 39, leaving Gai Amatsu's redemption storyline to be shortened down.
  • The show would've almost ended at episode 41 because by the time production finished the last episode, Kamen Rider Saber had finished filming the first two episodes.
  • In the original scripts, Aruto Hiden and Kamen Rider Ark-One were originally two different entities, but was revised to instead have the two be the same person as a result of Izu's death by Horobi.
  • Owing to long time Kamen Rider suit actor Seiji Takaiwa being casted as Horobi's suit actor, the long-term plan for the show's ending would be to have Horobi fight against Zero-One, but the process of how they would get there was undetermined at the time.

From May 17, 2020, to June 14, 2020, Zero-One aired a series of recap episodes for five consecutive weeks, the two-part "President Special", focusing on Aruto and Izu, the "Shooting Special" focusing on Isamu and Yua, and the two-part "Super Job War" focusing on the Humagears throughout the series. In Kiramager, similar recap episodes alongside a televised broadcast of Episode ZERO and a special director's cut of Episode 1 and 2 were aired. During the airing of these recap episodes, both shows featured early bird appearances from futureIcon-crosswiki.png characters.

Shortly after Japan lifted its state of emergency on May 25, 2020, Toei announced that both Zero-One and Kiramager would resume filming with newly placed guidelines during filming to control any further spreading of the virus.[9] New episodes of both series resumed airing on June 21, 2020.[10]  On June 22, 2020, Toei announced that both Zero-One and Kiramager's summer films would be postponed until a new release date can be determined.[11]. The series wrapped up filming on August 4, 2020 and the finale aired on August 30, 2020.


After the show's finale, it was announced that the summer movie was to now premiere in the following winter. On September 12, 2020, Toei revealed a new form for Zero-One to appear in the film. The cast of the show relocated across Japan for Kamen Rider Zero-One: Final Stage performances, while the October issue of Televi-kun revealed production images and some plot details for the movie. In October 2020, Kamen Rider Saber: The Movie was announced and scheduled to premiere alongside Zero-One's film on December 18, 2020, leaving any potential crossover between the two in the rocks.


"Humagears, robots 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 Episode 1-28, 42-44[src]

"Humagears, robots equipped with artificial intelligence. Will they bring hope or despair to humanity? A young president of a new company specializing in A.I. technology fights to bring his dreams to life!"
―Opening Narration Episode 31-41[src]

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 bears witness to several terrorist attacks orchestrated by MetsubouJinrai.net, prompting the creation of an anti-Humagear military squad, A.I.M.S.. Upon inheriting his late grandfather's company and the Zero-One Driver, Aruto becomes Kamen Rider Zero-One and finds himself caught in the crossfire between MetsubouJinrai.net and ZAIA Japan, led by Gai Amatsu who wishes to rid the Humagear from society and take over the world.

Main article: Kamen Rider Zero-One Episodes

Each episode of Zero-One includes in its title a pronoun written in katakana instead of hiragana. The titles are also simillar to Aruto Hiden's speaking style, and sometimes pun on the Japanese word, akin to Aruto Hiden's jokes.

Similar to Gaim, the series is divided into 4 story arcs, much like an anime/manga series.

  • MetsubouJinrai.net Saga (滅亡迅雷.net編 MetsubōJinrai dotto Netto-hen, Episodes 1-16): Hiden Intelligence and A.I.M.S. face off against MetsubouJinrai.net, who seek the extinction of the human race.
  • ZAIA Workplace Competition Saga (ZAIAお仕事勝負編 ZAIA Oshigoto Shōbu-hen, Episodes 17-29) Hiden Intelligence competes against its corporate rival, ZAIA Japan, in a battle of A.I. Meanwhile, a mysterious figure recruits ZAIA's contestants to be Raiders.
  • HIDEN Manufacturing Saga (Episodes 30-35.5): Aruto establishes HIDEN Manufacturing after ZAIA Japan’s takeover of Hiden Intelligence while MetsubouJinrai.net seeks to fully revive.
  • Ark Saga (アーク編 Āku-hen, Episodes 36-45): Aruto and his allies battle against the newly autonomous Ark and its plans to destroy all of humanity.

Insert Themes
Movie Theme


  • 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).
    • Different from the Kabuto series, the transformation item also indicates the group side which the characters were sided on. 

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.[18]
  • 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 story arc has some variation of the same phrase in their titles.
  • Currently, Kamen Rider Zero-One holds the record for the most transformation devices with a total of 13 units.
  • Owing to COVID-19, Kamen Rider Zero-One is the first series since Kamen Rider Ex-Aid to conclude with 45 episodes and, alongside Ex-Aid is the shared second-shortest Kamen Rider series overall.
    • Coincidentally, both series share the same head writer.
  • This is the first series to have its standalone film to be released after the end of the series. Originally, the film was planned for a summer release, double-billed with Kiramager's standalone movie. Instead, both will be released separately after having been delayed. Zero-One's film is set to premiere in December, the month where annual Movie War films are traditionally released.
  • This is also the first series to have an international airing start a week after the end of the series.
