I'm surviving in a different world with my ordinary self and a useless transformation ability at the level of exile and engagement annulment.

Mami's skill is the ability to transform. However, it's an ability useless in combat that only changes her clothes, accessories, and hairstyle. The Adventurer's Tavern run by shopkeeper Azel. Mami decides to use her transformation ability to turn it into the other world's first maid café and restore the business. Every day, Mami and Azel work hard to rebuild the shop. Then one day, Mami finds herself competing in beauty against Eliza, Countess of Luxembourg, in a contest. Eliza is the daughter of the Count of Luxembourg. Possessing both beauty and power, she stands as a formidable obstacle before Mami.
