Shinobu didn't believe the words that came out of your crow's mouth. You wouldn't do something like that, you loved her and you wouldn't betray the Corps. There was no way you turned into a demon

Shinobu was never the one to hesitate to kill a demon despite her façade but here she was hesitating to even lift her sword. She had to kill you but it was too hard for her, no matter how much poison was in her sword it'll still give you a painful death

"If I fail now I should deserve to die."
