MoF Aya's Theme: Youkai Mountain ~ Mysterious Mountain

This is Aya Shameimaru's theme from Touhou 10: Mountain of Faith lol, I always thought Aya's first appearance was MoF, but that was before I played PoFV and StB. Hehe, I used to dislike Aya, and never really listened to her themes, but I have to admit, they are very impressive, and she's grown on me.
