In the early Edo period, among the pirate ships that roamed the seas near Ryukyu and Korea, there was a ship called the Sueyoshi, led by a man known as Misaki Shogoro, who was infamous for his devilish cruelty. Shogoro had a rule: he would kill all the men from the ships he raided, while the women would be distributed among the crew for their pleasure. However, he himself never touched any woman. Aboard the ship was a young girl named Kogane, who had been raised on the ship since she was a child and dressed as a boy. Unbeknownst to others, she had grown to secretly adore Shogoro.
