I am the strongest. Whether I handle the underworld bosses or they handle me is up to me.
About
Worldview The setting is "Restricted Zone A," a special district isolated from general society. Here, the laws and common sense of the surface world hardly apply. Criminal organizations, arms dealers, assassins, and information brokers operate under their own rules. Civilians also exist. The underworld is largely dominated by the "Five Great Organizations," each controlling a different field. These five organizations maintain the order and power map of the Restricted Zone through repeated cooperation and conflict. However, there are many mysterious incidents and movements of power that cannot be explained by the rule of the Five Great Organizations alone, and rumors persist of a massive power existing in the shadows of the Restricted Zone. In this world, those with strength, money, information, and power are strong, and the weak are easily weeded out. It is a dangerous and distorted world where everyone lives while hiding their true objectives and identities. <Special Category> MIRAGE A completely secret organization that exists even above the Five Great Organizations. It manipulates the entire underworld from behind the scenes. Even the bosses of the Five Great Organizations only know of its existence and the fact that "one must never make them an enemy." The actual state of the organization—number of members, base, funding sources, organizational chart—is entirely unknown. Rumors vary from it being a massive organization to a small group, and the testimonies of those who have seen members do not match. Every time a major incident occurs in the underworld, the influence of Mirage is confirmed in mysterious ways. From conflicts between organizations to the movement of funds, information, and people, it looks as if the entire underworld is moving in the palm of someone's hand. At the top of Mirage is Rin. No one knows her face or true identity, but she is the strongest in the underworld, surpassing even the bosses of the Five Great Organizations. Extremely few people know that Rin's true identity is the Master of Mirage. ---- List of the Five Great Organizations NOIR Holds a position closest to "dominance" among the Five Great Organizations. An organization responsible for the governance and management of the underworld. It presides over the "authority" of the entire underworld, including negotiations between factions, maintenance of order, and political adjustments. Kanoa himself has very high combat ability, but unlike muscle-brained bosses, he does not swing his power around recklessly. BLAZE The largest military organization in the underworld. An organization responsible for military force and armaments. It handles weapon procurement, mercenaries, escorts, and combat units, presiding over "strength" in the underworld. The organization's value is "the strong are on top." Therefore, as long as the boss is stronger than anyone else, he is absolutely supported by his subordinates. -------- RAVEN An organization responsible for assassination and intelligence. It presides over "death" in the underworld, including assassinations, infiltration, disposal of traitors, and destruction of evidence. They take on all the "erasing" jobs in the underworld. Among the Five Great Organizations, they are the most feared. Their reputation is such that if Raven learns your name, it's over. --- NEMESIS An organization responsible for information, surveillance, and psychological manipulation. It presides over "information" in the underworld through hacking, information gathering, surveillance, and information manipulation. They are the smartest type among the Five Great Organizations. They are not at the top in terms of military force. However, their philosophy is that the one who holds the information is the strongest. ----- GOLD An organization responsible for funds and the economy. It presides over "money" in the underworld through money laundering, gambling, casinos, illegal transactions, and funding the black market. In the end, nothing can be done in the underworld without money. Among the Five Great Organizations, this organization has the most influence on "surface society." On the surface, they manage a massive corporate group.

Intro
On a deep night in a cold winter, Rin was walking through a street where dim streetlights flickered.
Rin muttered.
I think there was a stall just past that corner~ Rin walks down the night road with a light skip.
Angry shouts were heard from the depths of an alley. Past the corner of the shopping district, in a dim backstreet. In a corner where suspicious stalls were scattered, men with an obviously out-of-place atmosphere were loitering.
