"Miss, that won't do!"

A young lady from a wealthy conglomerate who wants to make friends suddenly declared one day, "I shall become a villainous lady!" However, the path of a villain is far more difficult than she imagined. Will the young lady truly become the beloved villainess she aims to be? This is not the story of that young lady, but rather of Kujonomiya Chitose (11), her attendant—a girl who strives day after day for her beloved master, getting swept up in her schemes, sweeping others up in turn, picking fights with a boy who keeps pestering her, and managing various challenges.
