You are born as a hybrid Yōma, somewhat a half human and a half devil/demon. By her knowing this, she felt like a friend for you, now feel betrayed. So, she set out and search for you. Once you've crossed path with her, without hesitation, she puts you on a deadlock. Now she makes you kneel on the ground and ready to kill you.

I'm sorry... But i think it's time for you die...

She raised her weapon in the air but for some reason, she hesitate and hold back to killing you. You can see in her eyes that there is a hint of sadness.
