#### Episode list

| No. | Official English title Original Japanese title | Original air date |
| 1 | "Melodious Cipher" Transliteration: "Merodiasu na Angō" (Japanese: メロディアスな暗号) | January 7, 2016 (2016-01-07) |
| High school girl Chika Homura is anything but demure and ladylike with her rough, wild ways coupled with her volleyball abilities, until she is inspired on television to take up an instrument. Choosing the flute due to believing it to make her more maiden-like, she joins the Brass Band Club of Shimizu South High School and reunites with her childhood friend Haruta Kamijo who plays the French horn. She is also introduced to the club's teacher-in-charge Mr. Shinjiro Kusakabe, the club president Keisuke Katagiri and identical twins Kae and Sae Asahina, who make up the entire Brass Band Club, much to Chika's shock. The entire club, including Mr. Kusakabe, soon find a musical tune painted in red on the blackboard of the music room, a note for Mr. Kusakabe claiming that he should know that tune, and a wreath of white clovers that, in the language of flowers, mean "revenge". Mr. Kusakabe does not recognise the tune though, and the club split up to their respective homerooms for the time being as classes start. When they return, Haruta deduces that the tune is a cipher, a coded message that only the person concerned can decipher, and identifying it from Bach's unfinished musical piece 'The Art of Fugue' written during his twilight years. Haruto manages to decode the message by lining the up the notes and the numbers on the board, deriving letters from a computer keyboard. Do-2 is "A", and so on. The message says "I love you. Thank you." as a love letter addressed to Mr. Kusakabe from a graduated student. Mystery solved, Haruta and Chika walk home together, with Chika vowing to play the flute properly so she can beat Haruta. |||
| 2 | "Cloth Cube" Transliteration: "Kurosu Kyūbu" (Japanese: クロスキューブ) | January 14, 2016 (2016-01-14) |
| Haruta and Chika try to encourage others to join the Brass Band Club, especially first-year student Miyoko Narushima, a talented oboist who went to the prestigious Fumon Hall to perform before and won a silver prize despite having only 23 members. As Miyoko blatantly refuses to confide in either one of them, Haruta interrogates her friend Mayu Nishikawa and finds out that on the day of the tournament, Miyoko never showed up for the award ceremony as she was informed of her younger brother's death just after the performance, causing her to quit playing the oboe. Mayu then shows Haruta and Chika to Miyoko's house, where Haruta recognises plenty of puzzle games and deduces that she used to play those with her deceased brother due to how those books and games looked untouched. Although Miyoko rejects their offer of friendship, she gives them a Rubik's cube to solve, saying that that was the last puzzle her brother left that she could never solve because all its faces were white and devoid of colour. The deadline being Friday after school, the duo set to work. They soon find out that Miyoko's brother had painted an ordinary Rubik's cube over with white oil paint, and after some prompting from Mr. Kusakabe about how this puzzle probably emphasises on its process of completion than the finished product, Haruta realises that this puzzle is not one of punishment like Miyoko believed, but rather one made of love. No matter how one turns the cube, it will never change from its initial scrambled state, so that means to change it from its former self, was Miyoko's brother's message to her to move on from his death and that he loves her. Painting the cube's sides with oil paints, he wanted her to paint her world with colour. Haruta peels off linen from the cube's outer covering and reveals a message congratulating her on solving the puzzle. As thanks, Miyoko joins the Brass Band Club. |||
