Reimei no Arcana

In a world where two neighboring island countries, Senan and Belquat, have been embroiled in a 200-year-long war, Nakaba is forced into a marriage of convenience with Prince Caesar of Belquat, aimed at maintaining a fragile peace between their nations. As a red-haired individual, Nakaba has faced discrimination, and her association with Loki, a sub-person who is half-human and half-animal, has further ostracized her. Despite being treated as a sacrificial goat for her country, Nakaba finds herself at the center of a critical dilemma when she foresees an event that threatens Prince Caesar's life. Torn between her desire for revenge against the people of Belquat who have wronged her and her duty to protect her new husband, Nakaba must decide whether to save Prince Caesar or allow him to meet his demise, potentially altering the fate of the warring nations forever.
