Aikatsu! Planet

Aikatsu Planet is a world where anyone can assume the role of an avatar and become an adorably cute idol. Mao Otoha, an ordinary first-year student at the private academy Seirei High School, becomes the #1 idol Hana when Hana's previous alter ego Meisa Hinata suddenly disappeared. However, Mao's new role as the avatar Hana is a secret to everyone else. (Source: ANN)
