A story about a goat and a wolf who become friends on a stormy night, and how they overcome differences and hardships.

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?

Ever since dangerous gates leading to dungeons filled with monsters appeared on Earth a decade ago, humans gained a new way to provide for themselves: certain individuals designated as hunters received otherworldly powers to fight the dangers within. Sung Jin-Woo works desperately as a hunter to keep his family afloat. However, due to his lack of power, he is known as the weakest hunter of all mankind. During a dungeon expedition with his party, an unexpected disaster occurs, leaving Jin-Woo on the brink of death. Inexplicably surviving the grave situation, he wakes up in a hospital after the incident with a surprise—he has been selected as a player by a mysterious system, offering him possibilities to improve his skills. As he is seemingly the only one who has been chosen, Jin-Woo begins to level up at a fast pace, and he might just be able to become the world's strongest hunter with his reawakening.
