Please tell a story about the music ya'll chose for this, it's incredible.
You mean the song in the trailer? It's the japanese OST for Kenshiro: https://en.wikipedia.org/wiki/Kenshiro
The story is quite simple, I just loved the anime when I was a kid :)
The italian version is also incredible: https://www.youtube.com/watch?v=YPIcdhjPG5I
