The anime's story takes place in the year 2020, near the Hareza Tower building plaza. This is an area under development currently but is expected to be completed by 2020. A girl gives chase to an owl she sees in Ikebukuro. Over the course of the anime, the audience witnesses the girl grow and learns about the charm of Ikebukuro, a place where "everyone can be the lead player."
The main owl character was designed by Yuru Souma, the winner of a pixiv contest. The tourism anime is the result of a partnership between Toshima's local government and Animate, whose head office is located in Toshima. Both parties hope that in creating the anime, they can establish another pilgrimage site in Ikebukuro.
