With the invention of anti-gravitational shoes known as Grav-Shoes, the ability to fly freely has become an everyday experience for the people inhabiting a four-island archipelago south of Japan. This invention has brought the people new ways of living and also a new sport known as "Flying Circus," where participants gain points by either touching floating buoys or their opponent's back. The gullible and clumsy Asuka Kurashina, newly transferred to Kunahama High School, enters this world of flight unknowingly when she is able to pull off a difficult maneuver the first time she participates in a Flying Circus match. Eventually, this leads her to join her school’s Flying Circus club. Led by their coach, Masaya Hinata, their members consist of the experienced Misaki Tobisawa and her overprotective friend, Mashiro Arisaka. Ao no Kanata no Four Rhythm follows this rookie group soaring high above the skies and toward their dreams, armed only with their unwavering passion against an uncertain future.

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.
