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...
even when there are hundreds of them.
.فإنّ الآباء تتعرّف على أصوات صغارها
selbst unter hunderten von Stimmen.

los padres reconocen
las voces de sus crías.

i piccoli anche tra centinaia di teste 
tutte uguali, dal suono della voce.
os pais reconhecem seus filhotes pela voz.
выискивают своих детей по голосу.
