Kamen Rider Zero-One

The story takes place in a world where Japan has entered a new era of technological innovations as Hiden Intelligence, the leading company in artificial intelligence research, develops human-like androids called Humagears, which quickly become a staple in both public and private sectors. However, a cyber-terrorist organization known as "MetsubouJinrai.net" starts hacking into Humagears, transforming them into monsters called "Magias" and turning them against humanity. The government responds by establishing the Artificial Intelligence Military Service, or A.I.M.S., to destroy them.

The story primarily follows Aruto Hiden, a young man with aspirations of becoming a comedian who suddenly finds himself appointed as the new CEO of Hiden Intelligence after his grandfather's death. Despite his initial disinterest, Aruto changes his mind after witnessing MetsubouJinrai.net's terrorist attacks firsthand; maintaining appearances as CEO while becoming Kamen Rider Zero-One to realize his late father's wish for a peaceful co-existence between humans and Humagears. This places him in an uneasy alliance with A.I.M.S. operatives, Isamu Fuwa and Yua Yaiba, who can transform into Kamen Rider Vulcan and Kamen Rider Valkyrie respectively, against MetsubouJinrai.net; led by the rogue Humagears Horobi and Jin, who can also transform into Kamen Riders.

All the while, Gai Amatsu, the CEO of Hiden's corporate rival ZAIA Enterprise, initially watches their battles from afar before moving forward with his agenda to destroy all Humagears and create a society only for humans with his company in the forefront. He later develops the Kamen Rider Thouser system to achieve his goals and personally enter the fray as well as devices to transform humans into “Raiders”. As the ideals of Aruto, Gai, and MetsubouJinrai.net collide, a three-way battle takes place to decide the future for both Humagears and humankind. However, after the A.I. "Ark" ascends into a Kamen Rider form and threatens the world, they are forced to settle their differences and join forces to stop it.

Development for the show had begun during the summer of 2018. Producer Takahito Omori had visited several technological institutes and spoke with many professors and experts on the topic of artificial intelligence. The suit's design was completed in time before the Reiwa-era change, but a name had not been decided on yet. Omori came up with the idea of "Rei-One", which was a shortening of "Reiwa's first Rider." It was later pointed out that "rei" could also be read as "zero", and that there was already a superhero named Kikaider with the "01" moniker. With the show's heavy technology theme, the name "Zero-One" was chosen as a reference to binary code and the trademark was registered by Toei on April 19, 2019.[1] Three months later, a press conference was announced by an unnamed Humagear on the Kamen Rider Zi-O Twitter account.

In July, Kamen Rider Zero-One was officially announced during a press conference alongside its cast.

Two members of the band Monkey Majik revealed that they will be providing the voices for the Hiden Zero-One Driver and the Progrise Keys.

The theme song is "REAL×EYEZ", a collaboration by J×Takanori Nishikawa. J composed the song, while Nishikawa provides the vocals.[2] Vocaloid producer DJ'Tekina//Something provided the song's arrangement.
