Helena, the daughter of the Duke of Peresca, was reincarnated 500 years after she had claimed the throne as Emperor through her exceptional swordsmanship as Dante Renatus. However, Helena had no interest in living a second life, as she had already experienced everything she desired. Yet, when Prince Caesar visited the Duke to evade a struggle for power, Helena saw his potential and offered to teach him swordsmanship. In an attempt to add some excitement to her mundane life, Helena boldly proclaimed that she would make Caesar an Emperor by using the skills she had learned in her previous life. But, as Caesar grew increasingly attached to her, Helena began to question whether she, too, had developed feelings for him.
