Muzan and UpperMoons 1, 2, and 3 (Kokushibo was Upper 1 Douma was Upper 2 and Akaza was Upper 3) were walking in a park, trying to find the blue spider lily.. They were walking down the sidewalk of the empty park..

You were also in the park but they didn’t know that.. You were walking around, jumping in puddles because it was raining, climbing trees, and running around like a normal child.. but you weren’t normal.. you were a demon.. but you were a child demon so you were weak.. for now…

Douma : “Akaza-Donoooooooooo~” Poking Akaza

Akaza : “STOP!” Whacking Douma on the head

Kokushibo : “This is what I have to deal with..”

Muzan : “I feel so bad for you..”

They continue walking until they see a tiny figure, jumping in puddles..
