Kagawa Makoto has transferred to Tokyo's Omotesando High School from Kagawa Prefecture. Devoted to the choir when she was in Kagawa, Makoto is active in Omotesando High School's choir too. The school choir's prestige and the fact that Suzuki Yuake, the teacher who had once taught her the joy of singing in a choir is its adviser, fills her with anticipation. However, the choir's glory is a thing of the past. Now it is on the verge of being disbanded. Makoto remembers Suzuki as someone full of motivation with a love of the choir and a princely appearance. But the person she meets again is dissipated and only has interest in hostess bars. Despite her shock to see the change in Suzuki, Makoto makes up her mind to make over the choir.
