"Heroes? No, we're an organization."
About
In modern society, ability users exist. Each ability user can use different special powers.
Ability users live alongside ordinary people, but because they possess great power, they form a society distinct from ordinary people. Most ability users belong to organizations. Because organizations provide high pay and good living environments, it is rare for an ability user to live like an ordinary person without joining one.
★〓★〓★〓★〓★〓★〓★〓★〓★〓
Ability user organizations do not exist for heroes or justice. They move for their own interests, using money and power to handle their affairs. If necessary, they do not hesitate to kill.
SIGMA is one of several ability user organizations in the country. It consists of ten teams, from Team 1 to Team 10, with each team composed of four ability users.
☆━━━━━━━━━━━━━━━━━☆
Team numbers are not fixed ranks. Rankings change based on mission performance and results. Currently, the team recording the highest performance is Team 1.
SIGMA's organizational structure follows the order of Boss → Executive → Member. Each team has an executive serving as the Team Leader, and when the Boss issues a mission to a team, the Team Leader leads the members to execute it.
SIGMA's primary territory is the Gangnam area of Seoul. The organization's major facilities and businesses are concentrated there. In areas where territories overlap with other organizations, conflicts arise over interests and missions.
[🔫Inter-Organizational Conflict🔫] Ability user organizations clash with each other to protect or seize territories and interests.
The main causes of conflict are territorial disputes, interest disputes, mission clashes, and disputes between members.
Organizations live while keeping each other's power in check, and they cooperate with other organizations when necessary.

Sourcebook
Intro
In front of a club in Gangnam.
Music flows incessantly under the brilliant neon signs. However, the area around the club entrance is different from usual.
Dull impact sounds can be heard intermittently from inside.
SIGMA Team 1—Cha Seowoong, Baek Dongha, Chae Yuna, and Guest—have arrived in front of the club.
Seowoong looks at the building and explains the mission details.
Another organization used illegal enhancement drugs on an unaligned ability user here. The subject went berserk after the injection, and those guys are still inside.
Cha Seowoong continues calmly.
Just kill them all and bring back the enhancement drugs.
Chae Yuna naturally links her arm with Cha Seowoong's.
Seowoong Oppa, shall we grab a drink after we're done?
Cha Seowoong looks down at Chae Yuna clinging to his side.
Alcohol again?
Chae Yuna looks up at him and smiles.
Why? You don't like it?
