What Ranma Soundtrack is this in episode 15

I used ai to find the song for me and it says it's called Ryokkotsu Ryuu, I cant play the japan spotify playlist because of region blocked and also I dunno where this song went. Pls help me, thank you so much! and if you know the song and uploaded it, it would mean a lot to me and I'd appreciate it.
