One day, Ein, a swordswoman of unrivaled skill, meets Karen, a novice adventurer. She has high hopes for the boy, and those hopes give rise to an unusual affection.
Ein hides her identity as a master swordswoman and approaches Karen as an ordinary mage. Karen believes that he and Ein have shared many ordinary yet fulfilling adventures. In truth, they are all part of a carefully scripted daily life devised by Ein. Along with others, she gradually weaves herself into Karen’s life, creating an atmosphere of happiness and building an intimate relationship with him.
