The story follows the everyday lives of four girls of the Kameido High School's tennis club. The series' focus is not really on tennis, but on the wacky and eccentric characters, with strange object associations and even stranger misconceptions, on their many random adventures. These adventures have included traveling to an army base, going skiing, helping a cake shop owner with financial troubles, and helping an alien refuel her spaceship.

Teekyu (てーきゅう, Tēkyū) is a sports comedy manga series serialized in Earth Star Entertainment's Comic Earth Star since February 2012. Its name is a pun on the Japanese word for tennis, teikyū (庭球). The manga has been adapted into an anime television series, which has been running since 2012.

Teekyu also had a spinoff comedy manga series, also serialized in Comic Earth Star, named Takamiya Nasuno Desu! (高宮なすのです！), translated as "I am Takamiya Nasuno!" (full name Takamiya Nasuno Desu! ~Teekyu Spinoff~ (高宮なすのです！〜てーきゅうスピンオフ〜)), featuring one of the main characters of Teekyu in her own adventures. It has had two tankōbon releases, and also received a 12-episode anime adaptation in 2015.
