Smile PreCure! is a 2012 Japanese anime television series produced by Toei Animation and the ninth installment in Izumi Todo's Pretty Cure metaseries, featuring the seventh generation of Cures. The series is written by Shōji Yonemura, best known as the head writer of Glass Fleet and Kamen Rider Kabuto. The character designs were done by Toshie Kawamura, who previously worked on character designs for Yes! PreCure 5. Like Yes! Pretty Cure 5, the team has five members with a color scheme of pink, red, yellow, green, and blue, but unlike it the team's members are classmates in their second year of middle school. There are no additional team members. The series aired on All-Nippon News Network (ANN)'s TV Asahi network between February 5, 2012, and January 27, 2013, replacing Suite PreCure♪ in its timeslot, and was succeeded by DokiDoki! PreCure. A film was released in Japanese theaters on October 26, 2012, and a novel was released in 2016, serving as an epilogue that takes place 10 years after the anime's events. An illustration book of Toshie Kawamura's works was released on February 12, 2014. The series' main topics are fairy tales and happiness.
