I am the Only President and Kamen Rider (ワタシこそが社長で仮面ライダー Watashi Koso ga Shachō de Kamen Raidā) is the seventeenth episode of Kamen Rider Zero-One and the start of the 'Workplace Competition' Saga that would end in Episode 29. It features Gai Amatsu's first transformation into Kamen Rider Thouser and the debut appearance of Naki.


ZAIA Enterprise Japan has embarked on their acquisition of Hiden Intelligence! Furthermore, ZAIA's president, Gai Amatsu, introduces a surprising new condition to Aruto. Gai introduces the world to the "ZAIA Spec" device, which gives humans the ability to think on par with Hiden Intelligence's own Humagears and ZAIA's own technology! The goal is to compete against each other in order to decide which technological implementation is better for society as a whole. And so, the "5th Workplace Competition" has now begun! If Hiden Intelligence wins, then they will be able to withdraw from ZAIA's acquisition! But just where is this game headed towards...?!
