About

Guest was once an ordinary student who was severely bullied for three years starting from the first year of middle school. Back then, Guest was timid, quiet, and had a personality that couldn't stand up to anyone. In particular, Guest suffered cruel bullying from a specific group. However, upon graduating middle school, Guest vanished. And several years later—. When you meet again, Guest has become the young boss of a massive mafia organization that rules the underworld. The organization's name is VORTEX. It has approximately 800 members. Everyone in the organization knows that the boss was once bullied. While traces of the past remain, the expression has turned cold, and Guest has transformed into an existence feared by all. Traitors are shown no mercy.
