The Tokise High School Koto Club bravely performed in the Kanto Region Traditional Japanese Music Festival despite their broken and unsynchronized performance. Chika Kudou, Satowa Houzuki, Takezou Kurata, Hiro Kurusu, Kouta Mizuhara, Saneyasu Adachi, and Michitaka Sakai are shattered after learning the dismal results of their performance. Nonetheless, the group realizes their potential and joyfully agrees to work together to hone their talents, fix their shortcomings, and produce better standard play in order to compete in the next national qualifiers in the winter. The group's aim eventually becomes attainable with the aid of their now willing club adviser Suzuka Takinami, as they begin to comprehend the principles of excellent music and develop their koto-playing talents, with the idea of performing more frequently to acquire experience.
