However, Yuri Oshimoto, a new member, is often the only sane one amidst her eccentric and silly upperclassmen. Among them is Kanae Shinjou, who despite being a member of the tennis club, is incapable of playing tennis; Marimo Bandou, an unpredictable pervert hailing from Kansai; and Nasuno Takamiya, an airheaded and enigmatic wealthy girl who attempts to solve every problem with money. Whether all four are present or not, this tennis manga is guaranteed to leave readers in fits of laughter throughout its run.
