Story
The five spirited middle school girls of the Shiratama Middle School Soft Tennis Team have high hopes in winning tournaments and making it into the nationals. There is the energetic, always enthusiastic klutz Harukaze Asuna, the strict Sawanatsu Kotone, very skilled in Karate, scares easily, but has a decidedly violent streak, the busty air-headed glutton Akiyama Chitose, captain of the team but actually the least skilled, the sporty, tanned Fuyukawa Kurusu, a soft tennis ace, who loves to wear strange masks and scare Kotone, and finally the blond-haired exchange student from the UK, Elizabeth Warren, a gifted "real" tennis player with a crush on sensei. Together with Mishimagi You, a former tennis prodigy as teacher and coach, the team's high goals might well be attainable. But will the quirky personalities of these girls be an asset or a hindrance in this endeavour?
