A competition of ups and downs! A final chapter of confession and tears!!

The school festival is here and the S Orchestra is to perform without the aid of Chiaki, who is busy practicing with the A Orchestra with their performance. Chiaki discovers what was missing from his playing courtesy of the S Orchestra, but Stresemann tells him to disregard it for their upcoming performance after insisting on it throughout all his practices. The pieces performed in this episode are Piano Concerto No. 2 by Sergei Rachmaninoff (brief) and Rhapsody in Blue by George Gershwin (pianica version).
