This is the story of a group of girls who are aiming to become professional ping pong players. Their training center and table tennis club is named 'Seishin Girls' Table Tennis Club'. This club was founded by a pair of female high school students, Harue Akado and Momoko Matsudaira. The club was opened in a facility owned by Harue's family's company. There is a reason why the table tennis club was started in this particular facility. It is because this club is located in the basement of a building that is owned by Minami Uehara's family.
