The Eccentric Doctor of the Moon Flower Kingdom

When the prince of the Moonflower Kingdom travels to Ran Province, he and his companion Shiei are attacked by highwaymen sent after him by the concubine Ro. In the next town, they are sent to see the doctor Koyo. With her assistant Shingdam, she manages to save Shiei. Her knowledge of medicine and her surgical skills impress Prince Keiun. In the land, it is customary to banish illnesses with rituals, which have only limited success. To compensate her properly, the two noblemen take the doctor and her assistant back to the capital. Keiun wants to use Koyo's skills to help others in his kingdom and spread her knowledge. But the young, beautiful, and eccentric woman soon encounters resistance, and the prince remains in danger.
