Seven Seas Entertainment licensed the The Eccentric Doctor of the Moon Flower Kingdom manga for English release, and describes the synopsis as:
In the faraway lands of the Moon Flower Kingdom, people have long relied on healing methods shrouded in superstition with dubious results. When the young Prince Keiun goes in search of more reliable remedies, his party is attacked by mysterious assailants, and he ends up witnessing a never-before-seen lifesaving procedure that shocks him to the core. Even more surprising, the one who performs this medical feat is a beautiful, yet slightly odd, teenage girl named Koyou! Just who is this girl, and why is the prince being targeted by assassins? Shadowy conspiracies, medical intrigue, and romance abound in this beautifully illustrated shojo manga!
