The key recommendation is to combine the Rakshasa and the skeleton (the Rakshasa and the skeleton that are separated and reunited). There are many versions, and I personally like the Hatsune version the best.

There is also the V family's dark fairy tale series including the one above.

And if you don’t pursue the meaning of the lyrics but just feel it, Snow’s Feather and Shi’s Wind also sound good.

In addition, in terms of pure music, the puppet's death dance is very similar to that of a still doll.

Final complaint: In fact, in terms of weird atmosphere, I personally feel that pure music is much better than songs.
