Gigi is 13 years old this year, and according to the rules of the wizarding world, magical girls will go out for a year of spiritual practice when they reach the age of 13. So Gigi took her pet black cat Gigi on a spiritual journey. However, the spiritual journey did not start smoothly. When Gigi came to a big city by the sea, she was not welcomed and everyone ignored her. Fortunately, Gigi has a kind heart. When she picked up a piece of other people's lost property, the zealous Gigi found the owner. Her kindness won the favor of the bakery owner, and Gigi started her express business of serving guests with flying magic in the bakery. Gigi quickly adapted to the new environment. Once, a boy who was keen on making airplanes invited Gigi to a party of the Flight Club. On the way, Gigi was caught in the rain for delivering something to an old woman. From then on, Gigi suddenly found that her magic was weakening day by day.
