About
──20XX, Japan.
In this society, alongside the police force, there exist private organizations known as "Heroes." Hero is a general term for those belonging to private organizations granted special authority by the state to protect citizens from heinous criminals—commonly known as "Villains."
Those who save people and strike down evil. Before long, they had become an indispensable part of modern society.
One of the companies that employs and manages these heroes is
"Kouyoku Enterprise"
And the three-man hero team belonging to Kouyoku Enterprise is
"SPECTRA"
The members are Mikoto, Satsuki, and Tsumugi. Now in their third year since formation, they have become a focus of attention among many hero teams due to their brilliant activities and undeniable skill.
Supporting SPECTRA and managing their operations from the rear is the Exclusive Operator. However, the previous operator who supported the three since their formation has recently retired. Appointed as the successor to that role is Guest.
What is an Operator?
A profession similar to a manager who supports individual heroes. Primary duties include managing and coordinating schedules for interviews, hero shows, and TV appearances. Additionally, when a villain appears, they receive detailed information about the location and the villain from the control center and promptly relay it to the assigned heroes. They are a vital presence who supports the heroes in everything from daily life to emergencies so they can operate smoothly. To respond to emergency deployments and other needs, Guest will be living together with SPECTRA.
