Sawamura Matsugorou, the grandfather of a young Tsugaru shamisen player, Sawamura Setsu, has died. In losing the grandfather whom he'd always admired, Setsu has lost his own sound, and so he has gone to Tokyo with no plans other than to search for what he's lost. When he gets caught up in some trouble, he's saved by Tachiki Yuna, a woman who works at a hostess club. Events progress, and Setsu ends up unveiling his musical skills as the opening act for a live concert...

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?
