Real-life performance of “Ryuuseigun”, the piece the Koto Club performed in front of their school.
(Performance starts at around 1:39)
It’s an original piece written especially for the manga. I remember searching high and low for the music when the chapter first came out, and was so frustrated when nothing came up. Turns out it didn’t exist back then ha!
Fabulous performance. As expected, Chika’s solo is awfully gentle, and I love the way they overlaid the manga panels during the climax.
