Nisemono ni Ubawareta Seijo no Chii, Nan to Shite mo Torikaesa... Nakute Ikka!

Ilia, a holy saint, once found true happiness in using her powers to help the people of her homeland. But one day, her life is turned upside down when her cousin, Mary, steals everything from her and has her exiled from the country. Freed from her duties at last, Ilia decides to set out on a journey, determined to live a life of her own. She thought since she’s been cast out anyway, she might as well live freely, without being bound by a mission. Along the way, she encounters Aktol, the first prince of a neighboring kingdom. Desperate for his country’s prosperity, Aktol makes a heartfelt plea, “I don’t care if I have to give you everything I have, but please become the saint of my nation!” Though she never planned to return to a life of responsibility, Ilia chooses to take up the mantle of a saint once more. But what awaits this saint with a troubled past and the prince devoted to supporting her on their path ahead…? The story of a new future forged together begins. https://www.cmoa.jp/title/332925/
