In Hinashi Town, where he resides with his father and grandfather, who makes sun umbrellas, lives Kai, a young middle schooler. Originally from Tokyo, Kai moved back to this small fishing village after his parents divorced. He struggles to express the complex emotions he has for them and feels lonely and pessimistic about his school life. One of his pleasures is posting songs he composes online. Kai's classmates, Kunio and Yuuho, invite him to join their band, "SEIRÈN." Reluctantly, he follows them to Merfolk Island, where they practice. There, they encounter Lu, a mermaid girl who sings merrily and dances innocently. As Kai spends more time with her, he begins to articulate his true thoughts. However, the people of Hinashi Town have long believed that mermaids bring misfortune. An event occurs that creates a rift between Lu and the townspeople. Then, the town is threatened. Can Kai's tears for his heart save the village?
