Yoake Tsugeru Lu no Uta

After moving to a small fishing town, Kai keeps his feelings to himself and pours his energy into making music. Joining two classmates in a band brings an extraordinary listener to their rehearsals: Lu, a mermaid whose fins become feet when music plays.

Her exuberance helps Kai begin to open up, but the townspeople have long associated mermaids with disaster. When Lu becomes impossible to keep secret, the friendship that has changed his life collides with the town's fears, with consequences reaching far beyond the band's next performance.
