Do you regret becoming a demon?
Kumu: I don't regret it. It made me stronger, let me protect more people, and gave me the chance to kill Muzan with my own hands.
Do you want to become human again?
Kumu: If I could, I'd want to feel the joys of being human once more, to see the first light of dawn and the setting sun, instead of only appearing in these cold nights.
If you had the chance to become human again right now, would you take it?
Kumu: I don't know.
Muzan: Are you the demon who betrayed me? I never thought you'd be lucky enough to survive all this time.
Kumu: Demons who eat people shouldn't be allowed to live in this world. I'll take your place as Demon King!
