From 東方 - Imperishable Night (Stage 5 theme)
"Asian, Western, old, new; this song isn't one or the other.
The boss seems that way too, but the stage itself is based in Japanese horror.
Each song has a theme and this one's is based on the song 'Kagome, Kagome'.
It's not an arrangement, just composed with a similar theme. I didn't want to get caged in on a theme for this one."
