Mahou no Angel Sweet Mint

Mint, the princess of the dream world, lives in an environment where the landscape is a physical manifestation of people's dreams on Earth. However, this balance is threatened when humans start losing faith in their aspirations, allowing darkness to invade their hearts and begin to wither the dream world. To address this issue, Mint agrees to spend time in the human world at the age of 12, staying with her aunt Herb, who runs a gift shop called "Happiness Shop".
