The five girls of the Shiratama Middle School soft tennis team want to win tournaments and reach the nationals, and their coach is Mishimagi You, once a tennis prodigy. Asuna is an eager, clumsy bundle of energy. Kotone is strict, trained in karate, easily frightened and prone to violence. Chitose, the busty and scatterbrained team captain, loves food and is the weakest player. Kurusu is the tanned star who enjoys scaring Kotone with odd masks. Elizabeth, an exchange student from the UK, is a talented tennis player with a crush on their teacher. Whether such an odd mix of personalities will carry them forward or hold them back is the open question in this comedic sports series with ecchi elements, adapted from Azuchi Ryou's manga.
