"u&i" is a program that provides an opportunity to learn about and deepen an understanding of minorities, like children with physical and developmental disabilities, and children from a foreign culture. The main character "i" is a so-called "normal" child. With each episode, "i," concerned about "u" with a certain disadvantage, finds themselves in a mysterious world. With the help of fairies, they hear out the problems that their friend is having, and in the process of learning more about them, "i" gains the ability to respect diversity and develop a compassionate heart.
