あらすじ
Three years ago, the celestial empire came under attack by the demons. With his kind on the verge of extinction, the celestial being and emperor, Kasin, is tasked to go down to the human world and find a way to restore peace. After three years without much progress, he encounters Daran, a merchant who has disguised herself as a man to travel and sell medicinal herbs. Daran was born with the power to heal anyone with a single touch. This ability makes her the exact person Kasin needs on his quest.
