Kai, a young middle schooler, lives in Hinashi Town, a lonely fishing village, with his father and his grandfather, a sun-umbrella maker. He used to live in Tokyo, but after his parents divorced he moved back to his parent's home town. Kai has trouble telling his parents the complicated feelings he has for them, and he's lonely and pessimistic about his school life. One of his joys is uploading songs he writes to the internet.

One day, his classmates Kunio and Yuuho invite him to join their band, "SEIRÈN." As he reluctantly follows them to Merfolk Island, their practice spot, they meet Lu, the mermaid girl. Lu sings merrily and dances innocently. As Kai begins to spend time with her, he starts to be able to say what it is that he's really thinking.

But since ancient times, the people of Hinashi Town have thought that mermaids brought disaster. Something happens that puts a huge rift between Lu and the townspeople. And then, the town is in danger. Will Kai's cry for the heart be able to save the town?

The aloof protagonist: a bookworm who is deeply detached from the world he resides in. He has no interest in others and is firmly convinced that nobody has any interest in him either. His story begins when he stumbles across a handwritten book, titled "Living with Dying." He soon identifies it as a secret diary belonging to his popular, bubbly classmate Sakura Yamauchi. She then confides in him about the pancreatic disease she is suffering from and that her time left is finite. Only her family knows about her terminal illness; not even her best friends are aware. Despite this revelation, he shows zero sympathy for her plight, but caught in the waves of Sakura's persistent buoyancy, he eventually concedes to accompanying her for her remaining days.

As the pair of polar opposites interact, their connection strengthens, interweaving through their choices made with each passing day. Her apparent nonchalance and unpredictability disrupts the protagonist's impassive flow of life, gradually opening his heart as he discovers and embraces the true meaning of living.
