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

Saint Ilias felt happy that she could help the people of her country with her own power. However, one day, her cousin Marie took everything from her and banished her from the country. Now that she'd been banished, she decided to live a free life unconstrained by any mission! So she set out on a journey in high spirits, only to meet Aktor, the first prince of a neighboring country!? Aktor, who wishes for the prosperity of his country, urged Ilias, "I don't mind giving my all to him! Become the saint of this country!" and Ilias decided to live as a saint once again, but...!? Where will the troubled saint and the prince who supports her go next? (Source: Futabasha, translated)
