ヒロイン？聖女？いいえ、オールワークスメイドです（誇）！

Melody Wave, a Japanese girl reborn in the kingdom of Théolas, has one dream in her new life: to become the world's most wonderful maid. She works as an all-purpose maid for a poor count's family, the Rutlebergs, where young lady Luciana is in her care, and her powerful magic turns cheap tea into a luxury brew and a run-down mansion into a showpiece. What Melody has no idea about is that this world is an otome game and she is its invincible heroine, the saint, so romance and the Demon Lord keep coming second to her chores.
