Twenty years into the future, the city known as Tokyo has evolved into one of the world’s few major high‑tech centers, now called Tokyo City. Ken Kanzaki, a young investigator in the Metropolitan Police’s Criminal Investigation Section, is renowned as one of the police’s finest sharpshooters. One day he is assigned to guard a high‑profile party hosted by the Zaizen Konzern, a global plutocracy. Suddenly, a swarm of specter robots descends upon the event, disrupting the festivities. The corporate commander‑in‑chief, Zaizen, is killed, and both Ken and Jun, Zaizen’s son, are fatally wounded by the robots. Other prominent guests, auto‑racer Ryo Aguri and wrestler Go Goda, also sustain serious injuries. Three guests are severely injured in the chaos.
