The Tokyo police attempt to arrest French agent "Louis", but he escapes using gravitational power, revealing himself to be a Contractor. He lands a short distance away; but while attempting to complete his payment, he is confronted by a mysterious masked man—the Reaper—who easily defeats him and demands to know the location of a "package". After the defeated man reveals that a girl named Chiaki knows the location of "it", the masked man, Hei, kills him. Still in pursuit, the Public Security Bureau Section 4 chief, Misaki Kirihara, is informed of the man's death and discovers his identity as a DGSE agent. She later discusses the man's death with her police squad. Following a lead, Yūsuke Saitō and Yutaka Kōno, members of the squad hang out in a hostess bar and end up pursuing a girl they believe to be Chiaki Shinoda. Hei, under the alias Li, manages to save her from the police. When Chiaki meets up with her supposed allies, she is nearly kidnapped, although Li manages to free her. In the ensuing chase, another French Contractor punches Li over the railing of a bridge and knocks Chiaki out with chloroform, capturing her. She escapes from her kidnappers with the assistance of a small cat and meets up with Li again, collapsing into his arms.
