The Labyrinth is an expansive space deep underground where humans live in clusters known as colonies. Over the years, the surface has become a distant memory—even perhaps only a fantasy to those who have never experienced its wonders. Making sure humanity survives the harsh conditions of the underground, a colony's citizens can take on a variety of specialized jobs. These include Workers, who mine precious ore to fuel the colonies, and Markers, who journey into the Labyrinth's surprisingly lush environment to bring back information that eases navigation. However, humanity also faces a threat to its existence—creatures called kaijuu whose sizes range from that of a small child to an enormous building, and are hostile to any human they see. Moreover, kaijuu that are large enough can force their way into the colonies, further increasing their threat level. Memenpu is a nine-year-old college graduate whose inventions have greatly benefitted the Workers in her local colony. Recently, however, she has been dreaming of a place with a neverending ceiling not bound by bedrock. These aspirations fuel her desire to become a Marker and explore the Labyrinth's vast unknown in search of such a fantastical place. Despite her father Gagumber's vehement disagreement, a certain incident with the kaijuu jumpstarts a dangerous yet exciting adventure that will surely alter humanity's course forever.

Tired of her rural home, recent college graduate Yoshino Koharu is desperate to lead a more exciting life in Tokyo. After a fruitless job hunt, she finally receives a part-time offer as queen of the bizarre Kingdom of Chupakabura, a rundown mini-attraction in the small agricultural town of Manoyama. However, Yoshino discovers upon her arrival in Manoyama that she was mistaken for a celebrity and the job offer was a mistake. Left with no other options, Yoshino reluctantly agrees to take on the role and aid the Board of Tourism in their efforts to revitalize Manoyama. Determined to bring excitement to the dying town with the help of local residents, the queen enacts a series of projects to highlight the beauty and charm of Manoyama's culture. Sakura Quest delves into the story of a tight-knit community that is struggling to balance change while also maintaining the rich traditions and bonds which define their identity.
