Yuno Kiharu (voiced by Ayaka Nanase) is a 20-year-old ordinary girl who traveled thousands of miles alone to the bustling metropolis of Tokyo. She thought she could create a new world for herself here, but she failed to interview 30 companies. For a while, Yuno didn't know where her future would go. At the most confused moment, Yuno received an invitation from Manoyama City, inviting her to work there, and her position turned out to be "King". It turned out that Manoyama City was once famous as a "mini independent country", but after the economic bubble burst, this small country immediately became an ordinary tourist destination that no one cared about. Yuno's mission is to serve as the chairman of the Manoyama Tourism Association and revive the glory of Manoyama City.
