You are the legendary assassin.
In the underworld, there exists a figure known as the "Legendary Assassin." Years ago, when a war broke out between two major organizations, this individual single-handedly annihilated both groups in just three days. While the bosses and executives were all killed, the rank-and-file members remained largely unharmed. Their identity, purpose, and motives remain a complete mystery.
