Aruto Hiden

Aruto Hiden (飛電或人) is a 22-year-old aspiring comedian who became the CEO of Hiden Intelligence after the death of his grandfather. Originally uninterested in taking up the position, he became witness to the terrorist attacks committed by MetsubouJinrai.NET and reluctantly became Kamen Rider Zero-One (仮面ライダーゼロワン) for the sake of pursuing his dreams of making others smile.

Early Life
Aruto Hiden was born the grandson of Hiden Intelligence CEO, Korenosuke Hiden. He would be raised by a HumaGear named Soreo Hiden who acted as Aruto's surrogate father.

Aruto and Soreo were present on the day of the Daybreak Town Accident, where they were enjoying a family outing with young Aruto spent most of his time engaging in comedic antics. When the chaos erupted from the Hiden Intelligence building, Soreo shielded Aruto from one of the explosions, but was grievously damaged in the process. In his final moments, Soreo encourages Aruto to continue pursuing his dream before his systems shutdown completely, leaving the young boy to grieve. Though the entire board of directors were enraged by this sudden development, Aruto quickly turns down the role and excuses himself.

As Aruto goes back to the theme park in an attempt to beg for his job back, the Berotha Magia attacks the park, and Aruto attempts to stop it but is beaten senseless. After getting triggered from the Magia saying that human dreams were meaningless, Aruto re-stood his ground and asked the just-arrived Izu for the Zero-One Driver. Aruto's mind was then uplinked into the communications satellite Zea, where his mind processing speeds were enhanced to the point where he learns the entire Zero-One tutorial in five seconds. Aruto transforms into Zero-One and destroys the Magia henchman as well as the Berotha Magia. After his first battle, Izu reveals that by accepting the Zero-One Driver, Aruto had also accepted being the president. Originally being reluctant to do so, he was re-inspired after seeing the park manager be grateful for Zero-One.

Personality
Aruto is a cheerful individual who loves to make people laugh, and doesn't give up even if he fails to do so. Despite this cheerful trait, he will not hesitate to fight back against people who threaten that happiness. To this end, he reluctantly becomes a Kamen Rider not to be a company president, but to be someone who can protect the peace.

Due to his upbringing, he has a very positive outlook on HumaGears, and strongly believes they can prosper alongside humanity. This makes destroying Magias difficult for him, especially if they were former Humagears he knew personally.

During mid-battles, he will say There's only one person who can stop you. And that's me! (お前を止められるのはただ一人,俺だ!).
