In the last days of the Tokugawa shogunate, there was a cute warrior, Souji Okita, who belonged to the armed police of the shogunate in Kyoto. Very few knew that Souji was not a boy, but a woman. Souji loved the vice-leader of the armed police, Toshizou Hijikata. Souji suffered from pulmonary tuberculosis and coughed up blood during a battle. Toshizou helped her but said that he did not care for the girl with a smell of blood. Souji had a real talent for swordsmanship and no one but Ryouma Sakamoto could compete with her. Ryouma was a liberal intellectual and tried to carry out a revolution without blood. However, the bloody Meiji Restoration broke out and Souji killed Ryouma who lost his dream. Because a friendship had sprung up between Toshizou and Ryouma, Toshizou got angry and slashed at Souji with a sword. Unwillingly, she unsheathed her sword and thought that she might get love if she was killed by the man she loved.
