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.

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.—Mwd

Humagear, created by the leading company for A.I., Hiden Intelligence, serve humanity's every convenience. But a cyber-terrorist organization begins hacking the Humagears in a conspiracy that turns them into monsters. Aruto Hiden has taken over at Hiden Intelligence, and along with the CEO's post, he also takes over the responsibility for Kamen Rider Zero-One by using his company's technology. Aruto tries to keep the peaceful world between humans and Humagears with his Humagear secretary, while A.I.M.S., a military squad, pursues the terrorists.—Kamen Rider Wiki
