Lotte no Omocha! 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.
