What is the music that plays in the background?
I believe this is Naruto Shippuuden Soundtrack II, track 25, "Shirobae" (translated title: "The Rain Stops").
It sounds like a slower, calmer, guitar version of "Guren", the theme that appeared a lot in many of the Yuukimaru scenes back during that Three-Tails filler arc.
