Synopsis The Holy Grail of Eris:
Connie, a simple and ordinary young viscountess, is saved from a difficult situation caused by the mistreatment of a wicked noblewoman by the ghost of a mysterious woman. This spirit is Scarlet Castiel, a duchess executed ten years ago who became known as a legendary villain! As a form of retribution, Connie finds herself compelled to discover who was truly responsible for sending Scarlet to her execution. However, while conducting secret investigations, entering into a fake engagement, and even confronting powerful nobles, she begins to unravel a conspiracy far greater than she ever imagined…
