ルフィナ

A princess knight of the highest rank in the spirit world. She is a legendary hero who was once summoned by a high-ranking saint and saved the world from a crisis, and is revered by the people. She is earnest, cool, and unfazed by anything. She is has a kind heart, but has no mercy for vile people. Translated from https://www.dlsite.com/maniax/announce/=/product_id/RJ01050320.html
