The Fallen Saint Dances in Vortex of War, 闇堕ち聖女は戦禍で舞う

Once upon a time, there was a saint named Alicia who fought against the demon king's army and defended her kingdom. On one occasion, her fiancé, the prince, falsely accused her of wrongdoing, leading to her public execution. Despite being abused by the people of the kingdom and feeling despair over their malice, Alicia made a final wish before her death. She wished for revenge upon all those who had wronged her, including her fiancé, and for her kingdom to be destroyed. However, her wish was granted by the demon king, who brought her back to life after her execution. With newfound power, Alicia vengefully sought out her enemies and brought about their downfall. Thus, the curtain rises on the tale of the vengeful saint who was resurrected from death.
