Those Snow White Notes Mashiro no Oto

Sawamura Matsugorou is a shamisen player of legendary talent. Upon his death, his grandson, Sawamura Setsu, lost his ability to play. Having lost his beloved sound, Setsu finds himself in Tokyo in search of a new sound to love. Tachiki Yuna, who works at a club, hooks him up with a gig to play there as a warm up act. Setsu imbues the sound of his shamisen with his many thoughts and feelings he has of others, still searching for his own sound and his own feelings.
