Stella has always been overlooked by her family and given no special talents by God. But when her sister loses the affection of her fiancé and retreats to a monastery, Stella discovers a newfound joy in cleaning. She becomes a maid to Cecil, a prince who has his own mysterious reason for staying in a room filled with toxic gas. Before long, Stella awakens to the power of *purification*, a skill that, when paired with Cecil’s *destruction* ability, transforms a fearsome magical beast into a gentle, fluffy holy creature! With her saintly powers growing, Stella starts to uncover the secrets of her true origins... and just who she really is.
