Dark Japanese Instrumental - 妖刀の血紋 | The Cursed Blade's Crimson Mark | Biwa & Shinobue

A woman kneels behind a drawn blade, and the same dry vermilion pattern surfaces across her face and the steel. She is not holding a cursed sword. She is the spirit the sword has always carried. Her hands stay perfectly still, proof that the curse answers to her, and not the other way around. 2 hours of Dark Japanese Instrumental music inspired by 妖刀の血紋 — The Cursed Blade's Crimson Mark.
