More infos on Hiden Aruto (I don't like the 1st part...)

Hiden Aruto - Kamen Rider Zero-One: In order to see his late father smile, he planned on becoming a comedian, but unfortunately lacks comedic taste. He's just scraping by as a well-known entertainer.
One day he was suddenly appointed as CEO of Hiden Intelligence by his grandfather Hiden Korenosuke as written in his will after he passed away. Although he initially refused, he transforms into Zero-One after seeing a rampaging HumaGear before his eyes.
Only those who have been appointed as CEO can utilize the Hiden Zero-One Driver. Then after officially assuming his position as CEO, he devotes himself to fight against the "http://ThunderclapofDestruction.net" terrorist group and the rampaging HumaGear systems.
