Charlotte Cocoliara is a duchess whose engagement to the crown prince has been annulled. She is compared to the heroine of a girl's game whose occupation is a "healer" and told to "pray for world peace, you boring 'dark magician' girl who doesn't even laugh. I'll change my job to a "healer" in an enemy country! Can't I change jobs? No, I was a player and I know how to change jobs." Using her knowledge of the game that no one else in the world knows, Charlotte easily changes her job to "healer," and is even recruited by a party of heroes who are struggling to conquer a dungeon...? Freed from the game's scenario, Charlotte's life as a free-spirited adventurer begins!
