Michi Hate no Mukou no Hikari

A village girl named Yuna is abruptly removed from her ordinary life after responding to a mysterious light in a white world. She awakens in the body of a saint, but faces hostility from the saint’s fiancé, the First Holy Knight Asyut, and indifference from the saint’s attendants, creating a tense and unwelcoming environment in the palace. Despite her confusion and isolation, Yuna attempts to carry out the saint’s duties as her substitute. Her efforts are disrupted when she uncovers a secret involving the saint beyond a spiral staircase.
