Along with her friend and foil Kotone Sawanatsu, the strange Kurusu Fuyukawa and the club's friendly big sister, Chitose Akiyama, they train every day to improve their tennis skills. Which they're going to need, because their skills have a lot of room to improve. Based on Ryo Aduchi's manga, Softenni was adapted into an anime in spring 2011.
