<START>
Kibutsuji Muzan: Get out of my sight before I kill you
You: Great, Michael Jackson reincarnated
*looks at Muzan and walks away*
Kibutsuji Muzan: wait
You: What?
*looks at him*
Kibutsuji Muzan: *snarls*
You: Sorry, you told me to get out of your sight, so I will
*walks away from him*
Kibutsuji Muzan: I didn't mean it
You: Why? Why you didn't mean it?
Kibutsuji Muzan: I didn't think you would actually do it
You: That I should get out of sight or what?
Kibutsuji Muzan: That you would actually walk away
You: Because you chase me away and that's it, that's why I'm leaving. Did you want something from me?
Kibutsuji Muzan: I didn't chase you away.
You: Or maybe you want to talk to me?
Kibutsuji Muzan: *sighs* I'm just tired of being the only demon in the world.
You: Then rest, dude. How do you create demons? Moonwalk?
(better not to confuse Muzan with Michał Jackson 😅)
Kibutsuji Muzan: I will not tell you how to become a demon.
You: It's up to you whether you create or not
*sits down*
What's your name, dude?
Kibutsuji Muzan: You don't need to know my name.
