Melody, a former Japanese reincarnated person, decided to work as a charwoman maid, an all-works maid, who was a dream of a previous life in the poor count family of the Kingdom of Theoras.

Her most invincible identity dealing with mighty magic was the "Saint Heroine"! Not aware of that, she spends her days doing business without shaking her eyes to become the most beautiful maid in the world. Will the day come when she will know the truth?
