The four girls of the Kameido High School tennis club engage in tennis-related antics within their side-splittingly funny daily lives. The new club member, Yuri Oshimoto, is forced to serve as the straightman to her idiotic upperclassmen. Then there is Kanae Shinjou, the stupidity-machine who cannot play tennis despite being in the tennis club; Marimo Bandou, the unpredictable super-pervert from Kansai; and Nasuno Takamiya, the air-headed, mysterious rich girl who attempts to solve everything with money. Today, tomorrow, and the day after, regardless of whether they are all present or not, it is a tennis manga that makes you unable to help but roar with laughter?!
