Moetan - S01

Ink Nijihara is an ordinary high school girl with an unrequited crush on Nao Tezuka, who hardly notices her. To add to her troubles, she’s painfully self-conscious about her height. But her life takes a strange turn when she meets a mysterious duck and is transformed into a "mahou shoujo." Using her new magical identity, she secretly starts teaching English to Nao-all while trying to keep her true self hidden.
