Rinka Urushiba works part time as a waitress to help out her unemployed father. By all accounts, her life in Tokyo is a relatively normal one--but her sense of normalcy begins to fade when she inexplicably sees a flying penguin one day. Chasing it all the way to the top of a building, she encounters more surprises, including flying goldfish and another person--a classmate named Kyoutarou Azuma--who can also see these strange things.
