Suterare Tensei Koujo desu ga Tekikoku de Seijo no Furi wo Shiteimasu

In the village church, Mira is treated with cold indifference by the villagers, who do not believe in her supposed saintly powers. However, Mira's true intentions are far from pious - she is driven by a desire for revenge against those who falsely accused and executed her. Reincarnated as a princess of a neighboring empire, Mira's peaceful days are cut short when her homeland is invaded and her parents are taken from her. Separated from her brother, Mira finds herself alone and adrift, with no one to turn to. The approach of magical beasts and the arrival of the cold-hearted prince Alphaus of the enemy nation threaten to upend Mira's fragile existence.
