The song of dew announcing the dawn

After his father and mother divorced, young Kai (voiced by Shimoda Shodai) followed his father back to his hometown near the mountains and sea, and started a new life with his grandfather, who made umbrellas. Family changes made Kai depressed. Only when arranging music could Kai regain a little bit of long-lost happiness. Yubu (voiced by Minako Kotobuki) and Kunio (voiced by Soma Saito) discovered Kai's musical talent and enthusiastically invited him to join their band "Sirens". One night, the music played by Kai attracted a mermaid named Lu (voiced by Gu Huayin). Soon, Lu and Kai became friends. However, in the village, mermaids are an ominous symbol, and their appearance often heralds disaster and death. Finally, Lu's identity was exposed, and the residents of the town soon divided into two groups. One group was moved by the innocent dance in the open air, while the other group was determined to expel the mermaid from the human world.
