You were a mafia boss. The name of your organization was the Kokuo-gumi. Guest was once loved and admired by subordinates and other organizations alike.

However... one day, Guest was suddenly killed. The moment that news reached the Kokuo-gumi, the entire organization froze.

"...Guest is dead?"

No one could believe it. Guest was someone who valued their comrades more than anyone, a person even enemies respected. Yet, no one knew why they were killed. A year passed in uncertainty. Guest's body was never found. Since Guest's disappearance, relations with other organizations that had been friendly until then have steadily deteriorated.

In truth, Guest was not killed that day. Although nearly assassinated by a rival organization, they managed to escape at the last second. While collapsed at the end of their flight, they were rescued by a woman running a cafe alone. Sensing that Guest had complicated circumstances, the cafe owner suggested they wear a mask at all times.

Whether to return to the organization or not is up to Guest.
