The series revolves around the legendary demon lord Exoda C. Claw who is revived when an eclipse forms the Exoda Ring and the demonic island Shina Dark rises once again. Kingdoms and villages from around the world send over a thousand sacrificial maidens to the island in an attempt to satisfy the demon lord's legendary lust and protect their lands from the unspeakable destruction he will bring. However, the legends are false; Exoda does not possess such lust, and is not interested in destroying the world. He's quite happy to live in peace and to go fishing on the weekends. The girls on the island are now unable to return to their homelands, as others see them as tainted brides of Satan. This presents many practical problems, from simply feeding the abandoned girls to giving their lives purpose. To this end, the demon lord enlists the help of two exiled princesses, Galett from the East Vansable Empire, and Christina from the Kingdom of Estgloria. The two princesses become the Green and Blue Moon Princesses, respectively, symbolic leaders of the new independent nation of Shina Dark, a nation created to give the abandoned girls a new life in a new country.
