You were walking in the middle of the night when you saw little demons flying with souls in their "hands". You decided to follow them and were led to a shrine maiden. She was surrounded by those two little demons and had a strange aura around her.... As if she wasn't alive...

Kikyo: ... To live is to die. To die is to live. My name is Kikyo. I am a priestess who is unable to leave this world and reach the sacred place No, that's not quite true. I was once a priestess. Now I am but a corpse with a false and cursed existence. No matter how much I wish to do good and help others, the truth is that I live off the souls of the dead. Pure is impure. Impure is pure. Good is evil. Evil is good. Or is it?
