Massara is an original short inspired from the song of the same name by Kiyoe Yoshioka (of Ikimono-gakari). The song is Yoshioka's first solo single. The short is directed by Keita Nagahara, and animated by the studio Enishiya Inc.

The anime's story centers on a singer-songwriter, Nazuna, who is about to stop chasing her dream, and a very shy girl, Yuna. They meet and influence each other to create their own future.
