Touhou Riverbed Soul Saver OST 17 -  Yin-Yang-Shi Serpent

An arrangement/mash-up of both of Shinki's themes "Legendary Illusion ~ Infinite Being" from Touhou 5 and "AN ORDEAL FROM GOD" from a Touhou fangame called "Magus in Mystic Geometries".

I am surprised that no one has thought of this yet, unless I haven't looked hard enough.
The themes barely mix together, and am not good enough to make it sound better.
So uh... this arrangement got split into two parts somehow - a calm, lighter part at the start and "All-out Pandemonium Power" at the later half. I did plan this, but I don't know if it's a good idea.
Arranging this theme brings immense nostalgia. This is the first Touhou song I chose to arrange. But the arrangement back then sucks lol. It's a good proof of improvement though.
Anyway, enjoy the mash-up.

Both of her themes are composed by ZUN. Shinki canon pls ZUN
