So yeah as I already mentioned above... this arrange is also tribute to and especially made for Alison (Alison Air Lines)'s popular comic book called "THE IMMORTAL WHO SAW THE DEATH OF THE UNIVERSE". It's a trilogy which asks the very deep philosophical question of "What happened when immortals faced the End of Days?" which can be read on this site by the way.

Here is the song that was released by Akatsuki Records that came with this doujin book by the way which leaves a good impact on the listener especially after or before reading this doujin.

I couldn't any information about this after searching for a while, is it in the tweets? I can't read moonrunes and Google Translate isn't showing anything related to it. It piqued my interest since that is one of my favorite doujins.

This is the first time I see a Touhou doujin get such recognition that a music circle decided to make arrange as tribute for it.
That or someone in Akatsuki Records personally like the doujin.
