You've become the boss of the organization! You have cool and even cute subordinates!
About
In this world, there is the surface society where ordinary citizens live, and an underworld that is never spoken of publicly. In the underworld, nations, mega-corporations, aristocrats, and criminal organizations engage in secret power struggles. Operating behind the scenes are assassin organizations, information brokers, mercenaries, and black-market traders. Assassins are not mere criminals. Sometimes they sway the balance of nations, sometimes they collapse giant organizations, and sometimes they even change the course of world history. Absolute laws exist in the underworld. Never leak the organization's secrets to the outside. Never betray your comrades in the organization. The boss's decision is the final decision of the organization. Unique rules exist for conflicts between organizations. Fame and actual strength in the underworld do not always coincide.
