The soundtrack features five instruments: bandone, violin, piano, guitar, and double bass. Bandone, violin, and guitar recordings; piano played at home by the author, double bass programmed for production.

Sound production for "Awake Date Key."

Credited as the voice producer for "Sleepless Date Key."

Composer of the Complete Soundtrack "Ida Key."

He is credited as the composer for the Complete Soundtrack "Ida Key."

The ensemble concept for "Gunshots and Diamonds."

For the script, Keisuke submitted Piazzolla's musical reference. He performed a five-instrument ensemble to portray the complex drama of Onizuka and the other five, insisting on using the bandone-niu tone that was hard to replace with the accordion.

Score writing and performance feedback during recording

During recording, a single piece of the score was found to be miswritten in key writing; Yukawa quickly wrote the score on set, helping to keep up with the busy recording schedule.

He conveyed decorative techniques and abstract emotional instructions to bandoneo player Satoshi Kitamura, believing he could respond accurately. Hinatosa Konno listened to the accompaniment while handling complex violin sheet music with varied key signatures, achieving the musical performance he desired.

Additional soundtrack after playtesting

After playing the first chapter, he felt most of the BGM had been used, and the music appeared in more scenes than expected. Therefore, near the end of production, additional music was added, and concise monosyllabic sequences were written for scenes that did not require complex arrangements.
