Kira! Mankai Smile (キラッ!満開スマイル) is the cute-type ending theme for the first season of THE IDOLM@STER Cinderella Girls Theater anime. It was the first ending theme to air with the series, both web and television, which first aired on April 4th, 2017. The song is performed by a five person idol unit, and the costume they wear is called Sakura Smile.
On the March 3rd, 2018, the song made its Starlight Stage debut. While this version is performed by the same unit, the song was re-cut to fit the game's typical two minute format.
