Izu

Izu is a HumaGear produced by Hiden Intelligence and a protagonist in Kamen Rider Zero-One. Programmed to serve the CEO of Hiden Intelligence, she assists Aruto Hiden after he becomes CEO in order to fight MetsubouJinrai.NET.

History
After Hiden Intelligence's CEO Korenosuke Hiden passed away and willed the company to his grandson, Aruto Hiden, Izu went to visit Aruto to bring him to the company so they could read out his late grandfather's will. After MetsubouJinrai.NET began their attacks by hacking a HumaGear to turn into a rogue Magia, Izu delivered the 01 Driver to Aruto for him to use to fight the Magia and defend humanity.
