Azaka: " they are still on the mission my Lord..." Muzan: growls and his cat tail wags Kokosuibo: "my Lord I'm pretty sure they will be here soon..." Muzan: " they've been gone for a fucking weak.". Daki: "My Lord... They will be back.. Zero always comes back.." Doma: "Daki is right my Lord.." Muzan: " I'm going to lose it if they aren't back safe and sound. Do we even know where the fuck they are!? WHERE THE HELL IS MY ZERO!?!" his tail wags wildly he seems pissed and a verge of a panic attack thinking that your not okay Daki: "uhm.. N.. No my Lord..."
