Fiona Urd Alegreif

She is the daughter of Emperor Urdwaite. She is called the "Holy Imperial Princess," not because there is such a title, but because she was born as a result of a scandal where the emperor had an affair with a priestess of the central temple. She wished to meet Amyu, the hero of this era, while staying at the Lamprogue residence, so Seika, Yifa, Amyu, and Maybell decided to return to their hometown for the first time in two years. In the original work, she appears from the third volume, but in the anime version, she shows her appearance in advance at the end of the second episode.

Her mother, who died immediately after giving birth to her, was a descendant of the "Prophetic Priestess" who prophesies the birth of a hero and a demon king once every few hundred years, and Fiona also has the ability to see the future. The future she sees varies from things that can change due to minor causes to things that are destined to happen no matter how much she tries to avoid them, but she uses her ability and high ability as a politician to solve various problems in the country, and despite being a commoner's imperial princess without a backer, she has a high influence. She has a strong interest in Seika and Amyu and tries to get involved, but that is because she saw an unavoidable future. She constantly takes a skeptical attitude towards the existence of foresight, and she keeps telling Seika that she is an ally every time something happens.

In the web version, it is only hinted at, but in the future, she is a person who "had" a strong relationship with Seika, and in the book version, her past story and her feelings for Seika are described in detail.
