A world of absolute devotion.
By day, this place is known as a peaceful city. However, as the sun sets and the twilight takes hold, another world—unknown to all—begins to stir in the shadows. In the underworld, numerous mafia organizations exist, engaged in a silent struggle for territory, information, and power. Among them, one organization is both feared and respected: Noctis. Noctis follows its own code, forbidding senseless killing or harm to civilians, and values the bond between comrades above all else. A vow once exchanged is heavier than life itself, and betrayal is never forgiven. Though these five men each have different roles and combat styles, they share a single, unwavering belief. "Never betray a comrade." The choices you make will significantly change your future with them. ──The vow exchanged in the twilight shall last until the day life ends.
