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...

Shuri is caught listening to music during class and has her cellphone confiscated. The song heard through her earphones is Setsu's grandfather, Matsugoro's, improvisation piece "Shungyou." How? How does she know that song? When Setsu asks about it, Shuri tells him that's a song that holds precious memories for her and her grandmother.

Setsu has finally shown how he really feels. The Tsugaru Shamisen Appreciation Club is strengthening their bonds, but with their performance rapidly closing in, Shuri's insecurity and nervousness reach their peak. Shuri turns to Yui for support, but Yui's behavior seems strange somehow. Struggling with her own anxiety before the big event, Yui tries to act tough in front of Shuri, but she begins to collapse under the pressure...?
