The band ASH DA HERO released a music video of the BOSJ theme song recently. Desperado shared some commentary on it.
"[Behind the Scenes info, for some reason]
I was fortunate enough to be included in this.
Halfway through the video, there's a scene where I take off my mask. I was the one who suggested this.
The staff didn't make a risqué proposal to a masked man like "Please take off your mask" or anything.
In fact, it was just the opposite. The direction I received from them was so considerate and gentle, I ended up making some suggestions of my own instead.
They were very courteous while filming, but the video was shot in a very short period of time so it wouldn't affect our matches that day. (We were forced to film this on the same day as a show because our schedules were all so full)
This was filmed with an extremely high level of care and consideration.
