Assassine

In a near-future setting, the era of rival criminal organizations vying for territory through their own crews has given way to a new and more sinister method of warfare. Rather than engaging in direct combat, these organizations have opted to pit their most skilled assassins against one another in a modern-day coliseum. The stakes are high, as the fate of each organization's territory hangs in the balance. In this treacherous landscape, Bando Eiji, alias "Gun Mania," has established himself as a top-tier assassin for the Kuroyanagi group. However, a new and formidable foe has emerged in the form of Kusano Nonomura, a young man driven by a burning desire for vengeance against Bando, the Kuroyanagi family, and the entire underworld. Kusano's actions are motivated by a deep-seated anger, and his very presence seems to signal the impending shedding of blood. As the conflict escalates, it becomes clear that the fate of the Kuroyanagi group and the balance of power in the criminal world hang precariously in the balance.
