Plot Motorcyclist Takeshi Hongo is kidnapped by the Sustainable Happiness Organization with Computational Knowledge Embedded Remodeling (SHOCKER), a sinister organization that transforms humans into brainwashed synthetic animal hybrids known as Augments, or Augs. Hongo is transformed into Grasshopper-Aug 01 but is set free by Ruriko Midorikawa, a former SHOCKER member, before he is brainwashed. SHOCKER sends one of its executive agents, Spider-Aug, to retrieve them and briefly captures Ruriko but is saved by Hongo in his augmented suit.

They retreat to a safe house where they rendezvous with Ruriko's father, Dr. Hiroshi Midorikawa. He reveals that Hongo is his masterpiece Augment to defeat the organization and chose him because Hongo wished for power after his father, a policeman, was killed by a suspect he was trying to arrest; he also explains that the life source prana allows Hongo to harness superhuman strength. They are discovered by Spider-Aug, who kills Dr. Midorikawa and kidnaps Ruriko again, only to be thwarted. After processing recent events, Hongo vows to use his powers for good and abandons the title of Grasshopper-Aug, dubbing himself "Kamen Rider." Ruriko is untrusting of Hongo but cedes to relying on his abilities.

Later, two unnamed government agents approach Hongo and Ruriko and convince them to form an alliance to take down SHOCKER in exchange for intel on the groups' activities. Ruriko reveals that SHOCKER is a secret society originally created by a billionaire with the goal of leading humanity to happiness. However, the billionaire committed suicide and left SHOCKER in the hands of an artificial intelligence that misinterpreted its creator's will, believing that mankind's salvation lied in its subjugation.

At the request of the government, Hongo and Ruriko defeat several Augs, including Ruriko's friend Hiromi, who was turned into the Wasp-Aug. When Hongo refuses to kill her, Wasp-Aug is shot by one of the unnamed agents using the Scorpion-Aug's venom. Later, Ruriko's brother, Ichiro, awakens as the Butterfly-Aug before she has a chance to complete a code that could suppress him. Ichiro kills several government agents by sending their souls to a hellish dimension called the Habitat Realm. Ruriko reveals that he intends to do the same to mankind because his mother was murdered randomly, an incident that made Ichiro outraged with humanity.

Hongo and Ruriko attempt to confront Ichiro, but are subdued, and Hongo is confronted by SHOCKER recruit Hayato Ichimonji, turned into Grasshopper-Aug 02. Hongo escapes with Ruriko but is maimed by Ichimonji; however, Ruriko succeeds in liberating Ichimonji from SHOCKER's brainwashing. Not long after, Ruriko is killed by the K.K.-Aug, who is soon killed by Ichimonji.

After recovering, Hongo views Ruriko's last will via his helmet; she reveals that she lost to Ichiro because his prana outmatched hers, that she transferred a code into Hongo's helmet that would neutralize Ichiro, and confides that her time with Hongo truly made her happy. After Hongo mourns her death, he fails to convince Ichimonji to work with him against SHOCKER and asks the two unnamed agents for a favor before confronting Ichiro.

Hongo is ambushed by a squadron of Grasshopper-Augs but is saved by Ichimonji, who dubs himself "Kamen Rider No. 2," and the two cooperate to defeat the Augs. When they confront Ichiro, he transforms into his complete form, Kamen Rider No.0, who proves to be powerful despite Hongo and Ichimonji destroying his source of prana. The duo succeed in removing Ichiro's helmet and replacing it with Hongo's, where Ichiro interacts with Ruriko's soul and the two reconcile. Having exerted their prana, both Ichiro and Hongo die.

Later, the two government agents honor Hongo's favor by bequeathing his helmet to Ichimonji, and reveal that they have secured Ruriko's soul to a safe location, and that Hongo wanted Ichimonji to carry on the name of "Kamen Rider" and defeat SHOCKER. On behalf of Hongo and Ruriko, Ichimonji agrees to work with the two agents, who identify themselves as Tachibana and Taki. With a new suit and a refurbished version of Hongo's helmet, Ichimonji interacts with Hongo, who transferred his soul into the helmet; and the two of them, now known as "Kamen Rider No. 2+1," ride on into the sunset.

Production Development Hideaki Anno first proposed Shin Kamen Rider after growing close with Toei Company producer Muneyuki Kii during the production of his 2012 film Evangelion: 3.0 You Can (Not) Redo. Planning for the film began in 2015 with Anno as director and screenwriter. Toei initially aimed for release in 2021, the year of the Kamen Rider franchise's 50th anniversary; however, production was delayed due to the outbreak of the COVID-19 pandemic.

The film was announced in a press conference on April 3, 2021, the 50th anniversary of the franchise's very first episode. Anno, who grew up with the original 1971 Kamen Rider series, expressed his admiration for the franchise, calling it "epoch-making" and expressing a desire to "give back in some small way". Executive producer Shinichirō Shirakura revealed the teaser poster, illustrated by Mahiro Maeda, as well as plans for a Japanese release in March 2023.

In September 2021, the film's official Twitter account announced the script had been finalized, and shooting was soon to begin. On October 10, the film's official Twitter account revealed that Hayato Ichimonji/Kamen Rider 2 would appear in the film. On January 1, 2022, it was revealed that Tasuku Emoto would play the role.

Design The film's version of Kamen Rider was designed by Anno, Maeda, and Ikuto Yamashita. A number of approaches to modernizing the design were considered, but the designers felt they steered too close to previous reimaginings such as Kamen Rider: The First and Kamen Rider Black. It was ultimately decided to go "back to basics," retaining the overall design of the original 1971 suit with only subtle alterations.

Yamashita also designed the film's incarnation of the Cyclone, Kamen Rider's motorcycle. Use of a fully computer-generated bike was proposed, but ultimately rejected due to concerns over budget and screentime. The designer realized it would be impossible to faithfully recreate the original Cyclone's silhouette with a modern bike; As such, production focused on finding a practical vehicle suited for the film's action sequences, which then served as the base for Yamashita's design.

Yutaka Izubuchi, a veteran designer who worked on the previous film reboot, Kamen Rider: The First, designed the Spider-Aug, the film's incarnation of Spider Man.

Filming Principal photography began on October 3, 2021. While the film's official Twitter account proclaimed filming wrapped in late 2021, Anno stated that he completed filming at the end of January 2022 in Shin Ultraman Design Works.

Like Shin Ultraman, several sequences in the film were shot on iPhones, using camera movements, lens sizes, angles, and zoom timing to mimic modern cinematic techniques.

Visual effects Visual effects for the film were created by Shirogumi.
