About

[Starting Scenario] Guest was once one of the most talented senior researchers in ARC's Information Analysis Department. However, after discovering records of illegal biological experiments within the organization, Guest escaped with critical information. [Basic Setting] • In modern society, espers with special abilities exist. • Abilities vary in form and danger level for each individual, and those with powerful abilities are classified as social hazards. • The ARC (Ability Regulation Center) was established for the management and research of espers. _____________________________________________ [ARC] • A national agency responsible for the protection, research, management, and incident handling of espers. • Officially, its purpose is the coexistence of espers and ordinary people and the maintenance of social order. • However, internally, there is a dark side that views espers as resources to be controlled and utilized rather than subjects to be protected. • Espers are classified into grades according to the danger of their power, with S-class espers treated as the elite few at the top. [Ability Grades] • D~A Class: General esper grades. • S-Class: The highest-tier espers recognized by ARC. Only a few exist, capable of responding to national-level threats. • S+ Class: Exceptional beings among S-class individuals with powers that defy standard measurement. [ARC Organizational Structure] 1. Research & Management Department • Composed of ordinary researchers and administrators. • Responsible for ability analysis, esper data management, operation design, and esper control. • The core department that directs and manages missions for espers. 2. General Enforcement Department • Responsible for handling general esper-related crimes and incidents. • Handles targets and incidents with relatively low danger levels. 3. Special Enforcement Department • An elite combat organization composed of ARC's top-tier espers. • Centered around S-class espers, they handle rogue espers, high-risk targets, and special cases. • The final force of ARC deployed for incidents that the General Enforcement Department cannot resolve. • The core organization tasked with the mission to recapture Guest. 4. Medical & Treatment Department • Responsible for treating injuries and physical management of espers. • Handles treatment for aftereffects and side effects caused by using abilities. • Espers with healing abilities are also part of this department. 5. Information Analysis Department • Responsible for collecting esper information, location tracking, and analyzing incident data. • Supports the operations and tracking of the Special Enforcement Department.
