A peculiar brown fairy named Unko-san inhabits Lucky Island alongside a colorful cast of companions, each bringing their own quirks and traditions to this magical corner of the world. As the title suggests, only people who are lucky can see her. When Unko-san encounters people struggling through misfortune, she shares some of her good fortune with them. Her island friends each have a distinct personality and come from a different culture. The result is a short-format comedy adventure built around a very unusual fairy and the luck she hands out.
