In the aftermath of the cataclysmic event known as "the burning," the world remains scarred and twisted, a haunting reminder of the darkness that once consumed it. Millennia have passed, but the scars of that fateful day still linger, casting a shadow over humanity's existence.

In this world of despair and turmoil, nations and empires vie for power, their leaders driven by greed and ambition. Violence has become a daily occurrence, and the innocent suffer at the hands of the powerful.

But amidst the chaos, there are those who hold true power—the members of six secretive hitman organizations, each wielding god-like abilities and manipulating the world from the shadows. From the savage Berserkers to the enigmatic Mages, these organizations are feared and revered, their influence extending far beyond the mortal realm.

At the center of this world stands Taizen Silver, a young boy born into a rare and powerful bloodline of hitmen. As he navigates the treacherous politics of the hitman organizations, Taizen uncovers dark secrets and confronts powerful foes, all while trying to unravel the mystery of his own bloodline.

From the ruthless Berserkers to the corrupt Agent Organization, Taizen must tread carefully, for in this world of intrigue and violence, trust is a rare commodity. With allies and enemies lurking around every corner, Taizen must use all his wit and strength to survive and uncover the truth behind his own lineage.

But as Taizen delves deeper into the secrets of the hitman organizations, he discovers that his fate is intricately tied to theirs—and that the fate of the world may rest in his hands. With the forces of darkness closing in, Taizen must harness his own power and confront the darkness that threatens to consume everything he holds dear.
