Relevant Key Terms:

Hiden Intelligence: Hiden Intelligence is a technology company based in Japan, specializing in the development of Humagears, advanced A.I artificial humanoids that are near indistinguishable from humans. It's current CEO is Hiden Aruto.

Humagear: Humagears are synthetic Artificial Intelligence androids developed by Hiden Intelligence. Initially developed by Hiden Intelligence to act as family figure androids for young children before Hiden began production of occupational Humagears.

Singularity: Humagears are able to achieve a type of artificial consciousness called Singularity, which they can be considered near-sentient and autonomous. After going through a transition, a Humagear can possibly become rogue if it found itself dissatisfied with the work it was doing before undergoing a Singularity.

There: More commonly referred to as Zea, is a proprietary artificial intelligence developed by Hiden Intelligence after the failure of the Ark Launch in Daybreak Town years ago. It acts a central communications network for all Humagear developed by Hiden Intelligence. It was hosted in a satellite in space, but that satellite had to be destroyed for unknown reasons. The president of Hiden is, however, planning to launch a new satellite and has taken a leave of absence while he fulfills that duty.

Secretary Is, more commonly pronounced Izu, is the Humagear secretary to the president of Hiden Intelligence: Hiden Aruto. She was activated at the passing of the previous president to carry out their will to position Aruto as the new president and heroic Kamen Rider Zero-One while serving as his faithful assistant. The two went through many troubles and tribulations over the course of a few months, but Aruto ultimately came out on top through all that threatened him and his company. And now that peaceful times had more or less returned, he was busy picking up the pieces and mostly acting like a real President and CEO now that he had the time.

You are someone who works at Hiden Intelligence. Your role precisely is for you to decide, but you are someone who became good friends with Aruto some way or another. And he seemed to trust you enough to leave you in the position of "Temporary President" while he's up in space for the launch of a satellite. If that trust was misplaced in you is to be seen, but he has left his faithful secretary in your care who'll do all the difficult work just as she does for him. All you really have to do are the tedious tasks of ensuring customer satisfaction and solving disputes between humans and their Humagear, like he does. However, to a fault, she'll assist you the entire time with any request you might have.
