I'm the President and a Kamen Rider

After the death of his grandfather Korenosuke, failed comedian Aruto Hiden is chosen to inherit his company Hiden Intelligence and take on the power of the Hiden Zero-One Driver just as a cyber-terrorist organization called MetsubouJinrai.net launches their plan to exterminate mankind. Initially turning down the position as his dream is to make people smile, Aruto changes his mind when a HumaGear gets turned into a Magia and threatens an amusement park; transforming into Kamen Rider Zero-One with assistance from Presidential Secretary Izu.
