The Princess of Urinalia, Alice Goldwet, has transferred to a Japanese high school to learn of the culture. She tells some of the customs of her homeland like drinking each others pee as a sign of friendship, initially grossing out the protagonist, Makoto Kimura, her classmate. He ultimately becomes a great fan of this and other urination-oriented customs of Alice's kingdom. From here the story develops in golden ways.
