Kamen Rider Zero-One

The recent death of the Hiden Intelligence CEO leads to his grandson's shock appointment as his successor, and his inheritance of the Zero-One Driver.

Representatives Isamu Fuwa and Yua Yaiba from A.I.M.S., a special government agency that investigates AI crimes, pay a visit to Aruto Hiden, the new CEO of Hiden Intelligence. They are suspicious that Hiden Intelligence is trying to cover up the events that occurred over at the amusement park...

As Aruto starts to settle in as Hiden Intelligence's CEO, he and Izu travel across Japan warning businesses with HumaGears of MetsubouJinrai.net's actions and show that the androids do have hearts. At their latest stop in a sushi restaurant however, Yaiba appears and challenges his idea.

After Isamu sustains serious injuries during his fight with Kamen Rider Horobi, he's taken to the HumaGear hospital for treatment and placed in the care of a HumaGear surgeon. Complicating matters however, MetsubouJinrai.net continue their attacks, leading Hiden Intelligence's VP Jun Fukuzoe to order all of the hospital's HumaGears to be shut down and forcing Aruto to choose whether to protect the life-saving androids or stop the rampaging Magias.

Hiden Intelligence's reputation took a significant hit following MetsubouJinrai.net's attack on the HumaGear hospital, so Fukuzoe commissions a TV drama series starring a HumaGear actor and world renowned human actor Shinya Owada as the lead in order to restore it.

Feeling that his HumaGear costar is unable to accurately convey profound human complexities, Owada threatens to leave Hiden Intelligence's drama series. While Aruto tries to persuade him not to, MetsubouJinrai.net's "Little Assassin" continues to gun for the world-renowned actor.

Following the attempt on Owada's life, the police and A.I.M.S. launch an investigation into Hiden Intelligence. To assist in their efforts, the former brings in a detective HumaGear and Izu's "brother", Was Nazortoku. Meanwhile, the Assassin HumaGear has grown tired of following Jin's orders and seeks to go his own way following his evolution.

After Aruto obtains the Shining Hopper Progrise Key and upgrades his powers to confront the evolved Dodo Magia, Izu begins to believe she's no longer qualified to be Aruto's secretary.

Two astronaut HumaGear brothers, Raiden and Subaru, storm into Aruto's office to air their grievances over being able to perform maintenance on Hiden Intelligence's Zea Satellite effectively and take their boss over to the company's Space Development Center. Meanwhile, Yua reveals MetsubouJinrai.net has a mole within their ranks and a red Kamen Rider enters the fray.

A.I.M.S. prepares to raid MetsubouJinrai.net's lair as the terrorists receive a power boost from the Ark's reactivation. Meanwhile, visiting his family grave alongside Raiden, Aruto has a realization about the HumaGears before being informed of MetsubouJinrai.net's activities; marking the beginning of a final confrontation between humans and HumaGears.

Following Jin's deadly attack on Izu in retaliation for Horobi's perceived death, Aruto confronts the rogue HumaGear in a final battle using the power of Shining Assault Hopper. All the while, Amatsu watches them from afar as he continues to prepare for what he believes will be the true battle now that he has Horobi in his possession.

With MetsubouJinrai.net gone, Amatsu begins his quest to absorb Hiden Intelligence into ZAIA Enterprise by developing technology specifically designed to allow humans to outperform HumaGears along his own Rider system, Kamen Rider Thouser. In order to save his company, Aruto must defeat his corporate rival in a five-part competition that will determine which of their respective technologies is more beneficial to society as a whole.

ZAIA Enterprise has set out to acquire Hiden Intelligence through a "5-Step Workplace Challenge"! The first challenge, the Flower Arrangement Challenge, had the human-HumaGear representative Rentaro Tachibana seemingly perform splendidly during the competition! However, Thouser ends up destroying and subsequently resetting the HumaGear who lost the challenge, the Flower-Arrangement Type HumaGear, Sakuyo Ichirin, much to Aruto's surprise! A bewildered Aruto mentions that "I was fooled by him", all the meanwhile a suspicious dark shadow slowly approaches Rentaro.

ZAIA Enterprise has successfully beaten Hiden Intelligence at the first match of the "5 Step Workplace Competition!" The next step in the competition involves selling houses, according to ZAIA's president, which consists of which company can sell more houses and make the most money, pitting HumaGears against humans wearing ZAIA Spec devices! ZAIA Enterprise will work alongside the industry's top real-estate salespeople, while Hiden Intelligence will make use of the real-estate type HumaGear, Smile Sumida, whose motto is "Selling and living with a smile!" But just where exactly is this game headed? And who is the mysterious hooded figure spreading the RaidRisers around the city?

The second stage of the Hiden vs. ZAIA corporate challenge continues as the latter's human representative resorts to underhanded tactics to defeat his HumaGear opponent, with the winner being ultimately decided by whoever can sell houses to millionaires on a budget. Meanwhile, Aruto begins to question himself after Gai tells him a good president is only as good as the profits they make.

With two losses against them, Hiden Intelligence must defeat ZAIA Enterprise in the next challenge, wherein a HumaGear defense attorney must face a veteran human prosecutor in court, in order to survive. As Aruto questions if the future of the defendant should be decided in a contest, the mysterious figure transforming humans into Raiders strikes again.

Following their lawyer HumaGear's destruction at Thouser's hands, Hiden Intelligence is on the verge of losing both the trial and the "5-Part Workplace Competition". Not only that, Aruto faces difficulties in determining the new Raider's identity. Just then, Fuwa comes forward with crucial evidence that could turn the tables on ZAIA's clean sweep.

In a unique turn of events, Aruto finds himself dealing with three crises at the same time. His Metal Cluster Hopper powers prevent him from using his other Progrise Keys in the Zero-One Driver, Chiharu comes to him demanding to be married to someone following the Hiden vs. ZAIA trial, and he has to introduce a HumaGear-Human marriage consultation service.

Amidst the human/HumaGear wedding, both the HumaGear groom and pastor are suddenly transformed into Magias just as a new Raider and Thouser go on the attack. When Aruto tries to use his Metal Cluster Hopper powers to stop them, he goes berserk once again. All the while, Gai continues to poison his mind with the idea that HumaGears are holding him back, but Izu attempts to help Aruto believe in them.

All communication with the Zea Satellite has mysteriously been cut off, so Izu summons the doctor HumaGear Bot to investigate as he's responsible for the manufacturing and development of HumaGear systems. After Horobi disappears from A.I.M.S.'s custody however, Bot reveals he created him along with the truth of the Zero-One system. Meanwhile, a new Rider appears on the roof of Hiden Intelligence with unknown intentions.
