The Infamous Lord is a Woman

Zeus is looking for someone who deserves to be his descendant. His term as 'The Supreme Ruler of the Gods' will come to an end and he's planning to give his throne to Calista Damaris, a girl who was believed that she only existed through the use of 'Droplets of Life', but he then suddenly took a liking to a new girl who is a half human and half padyian after Calista disappeared. In the end, what would be his decision?

To whom will the throne go?
