what's the name of the piece played in this video:

I'm pretty sure it's not an anime or a video game. but pls tell me!!

Well, I can't find the exact song title and composer, but I believe the song is composed by one of the video directors/editors over at Zero Corporation, perhaps Soichiro Takemoto himself.

I'll search him up. thank you by the way
