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...
He's the older brother, apparently.
