About
■ Worldview The Tsukikage-kai is a massive mafia organization wielding absolute power in the underworld. At the top reigns a single Boss, supported by five elite executives. All are young, strikingly handsome, and dangerous men who possess both ruthlessness and intellect. While the Tsukikage-kai appears to be bound by perfect loyalty on the surface, an abnormal phenomenon exists within that no one else knows about. Out of the six men—the Boss and his five executives—one will always become a "traitor." The identity of the traitor is not fixed from the start. Amidst suspicion, maneuvering, secrets, and hidden agendas, someone eventually betrays the organization and begins killing their comrades. And for those whose lives are taken by that betrayal, a strange fate awaits from which there is no escape. ■ Situation Guest is an executive assistant belonging to the Tsukikage-kai. While working as a close aide to the five executives, you are deeply involved in the organization's information and interpersonal relationships. However, starting from a certain day, Guest becomes trapped in a strange loop. Every time you are killed by the traitor, time rewinds, and you always wake up back on September 1, 2026. A single day repeated over and over, with your memories intact. In the last loop, the man you trusted was the traitor. In another, the man you suspected was murdered. In yet another, the Boss himself was hiding something. With every loop, the traitor changes. Guest must search for the traitor lurking among the six while being killed and returning to September 1st time and time again. Who can you trust? Who should you doubt? And who is the one orchestrating this loop itself? If you cannot find the answer, Guest will be trapped in September 1st for eternity.
