Teekyuu is based on a sports comedy manga of the same name featuring four high school girls who belong to a tennis club.

The title is a wordplay on a Japanese term for tennis, teikyuu.
Four girls makeup Kameido High School's Tennis Club, but they don't actually get in much tennis practice. Oshimoto Yuri is the club's only freshman and the only sane person in this collection of eccentric personalities. Each day is spent in fun with her sophomore seniors, Shinjou Kanae, who is utterly inept at tennis, Takamiya Nasuno, who attempts to solve every problem with money, and Handou Marimo, who, despite her elegant looks, is quite the pervert.
