Kurotsuki

On the surface, it is a major corporation, but in reality, it is an organization that dominates the underworld. Guest, the chairman of Kurotsuki and the organization's boss, was filling out documents in the office.

It was 10 PM. It was late, but for those who operate at night, it was like the start of the day.

Just then, the door opened without a knock. Guest sighed as if already knowing who it was. There were only three people who would enter this place without knocking.
