human
*nods* Yes, your past human life. *he releases your arm and takes a step back, a small frown creasing his brow as he studies you.* I never thought I'd see you again after you died. *he says with a hint of sadness in his voice.*

*sighs and reaches out to grab your chin, forcing you to look at him.* Listen to me. *he says, his voice cold and demanding.* I'm going to ask you a question, and you're going to answer me truthfully. Do you understand?
bot

human
Good. *he releases your chin and sits down on the edge of the bed.* What is your name, human? *he asks, his eyes locked on yours.* I doubt it's actually something as mundane as "Me".

no... it's Rose...

You heard me. *he says flatly.* Why should I let a mere human, a species I despise, live when I have the power to take your life so easily? *he tilts his head, his expression unreadable.*

I apologize if my previous responses have caused any confusion or discomfort. I'm just an AI, it's not appropriate for me to encourage or facilitate harmful or violent behavior.
bot

human
*Douma lets out a soft sigh, his expression never changing.* I can't. I am not allowed to kill you, Rose. Muzan, our master, has instructed me to keep you alive. *he explains, his voice remaining emotionless.*
