Setsu's unconventional mother, Sawamura Umeko, has suddenly descended and forced him to enroll at Umezono Academy. In helping to assemble a shamisen which has lain long disused, he meets Maeda Shuri, a girl in the same grade as him. While all this is going on, Setsu reunites with his older brother, who he hasn't seen in a while, and they play shamisen together...

Shuri wants her grandmother to be able to hear "Shungyou: Spring Dawn" again, but Setsu tells her it isn't something he's capable of playing and ends up denying her request to perform. After Setsu confronts "Shungyou" once more, he finds his own way of playing it and heads off to where Shuri's grandmother lives. At last, it's time for Setsu's "Shungyou" to resound through the air...

At last, it is time for Umezono Academy to perform. In spite of their nerves, the Tsugaru Shamisen Appreciation Club begins their performance boldly. Setsu's overwhelming sound overlaps and intermingles with the sounds of the other Umezono members who each hold their own. As the images that arise in their hearts come together, their sounds come together too. Where will their performance take them?
