Sacrificial Princess and the King of Beasts

贄姫と獣の王

The King of the Beasts and Demons regularly receives female human sacrifices to eat in order to assert the dominance of his people over the human race. However, for the 99th sacrifice, the human girl brought to the capital, Sariphi, intrigues the Beast King. In fact she isn't afraid of him or any other beast and even accepts her death without begging or crying as she has neither home nor family to return to if she were released. The King finds her intriguing and let her stay at his side as his consort despite being human. This is the story of how Sariphi will become the queen of the demons and beasts. (Source: Crunchyroll)
