PLOT
Having lost her husband, the second-generation head of the Nanjo-gumi, Shiho inherited the position of the third-generation head and works as a nurse while continuing her yakuza business. One day, a man named Masaya is brought to the hospital where Shiho works, severely injured and unconscious. Masaya's injuries are improving, but he has lost his memory. Several men who look like gang members appear and threaten Masaya, causing chaos in the hospital. Unable to bear watching this any longer, Shiho hides Masaya and takes him away from the hospital without telling anyone, intending to take care of him until he regains his memory...
