Houjou Marina

A first-rate international agent affiliated with the Ministry of Intelligence Gathering. She had a 99% success rate on cases she was assigned to, but she lost the passion to do her job after a certain case and is currently on leave. It seems her fiery spy life is behind her. Until a certain incident one day. A young boy ended up sneaking into Katsuragi Private Detective Agency’s office, and Yayoi, the agency’s chief, asked Marina to become the boy’s bodyguard. At the same time, multiple assassins seem to have infiltrated Japan, and they may be aiming for the boy’s life.
