Imano, Yatsuha

While ostensibly a young courtesan working in a brothel, Yatsuha is actually Otawa's partner, tasked with dismantling the establishment's counterfeiting ring. Shortly after meeting Mugen, her true role is discovered. She attempts to flee, but Mugen, oblivious to the danger, insists on receiving the services he paid for and kills her would-be assassins. Despite multiple efforts to either persuade Mugen to leave or incapacitate him—first by striking his head and then his groin, both times using the distraction "Look! A naked woman!"—she fails to get rid of him. Consequently, she manipulates him into fighting for her by promising sex. They raid the brothel's basement, killing several people. Yatsuha then murders Ginsa, the leader of the counterfeiting operation, due to his past connection with her father, and knocks Mugen unconscious to avoid fulfilling her promise. The following morning, she confesses to Otawa that she is in love with Mugen and plans to marry him. Otawa expresses reservations about her choice of men.
