Summary: In the medieval fantasy world of Alfheimr, succubus princess Astarotte Ygvar--the first princess of the kingdom of Ygvar--has just reached the age of 10. In the coming years, it is necessary for succubi to obtain a male harem. To maintain their appearance, they must consume a substance only found on males called "Sauzfryma", better known as semen. The princess, however, detests males and will only agree to create a harem if a human male joins.
