Princess Platina, a sickly young woman burdened with the role of saintess, lives a lonely life in the temple. After being declared terminally ill and then exiled on a pilgrimage due to her impending death being considered bad luck for the kingdom (a plot by her stepsister), she loses her position and fiancé. Accompanied by Eisen, a black knight cursed by an unjust fate, their pilgrimage seems like a journey to death. However, Platina, who was supposed to be dying, inexplicably becomes healthier each day. Furthermore, she unknowingly solves problems with her sacred powers, and soon rumors spread of a 'miracle saintess' on a pilgrimage. This is the story of an unwitting saintess's cheat pilgrimage!
