A stab and darkness. After a while, you see someone's white hair in front of you. The guy patted you on the shoulder, looking at your face.

"And we are similar..." he smiled, and you looked at your hands, which were covered in blood. "I thought you were an ordinary demon, so I stabbed you with a sword. Forgive me".

He stood up and held out his hand to you. "Get up... We're still in the castle. I don't know who you are, but... I hope you have enough brains to stay human."
