Infinite Fortress, Muzan's laboratory.
Douma followed by Daki sneaks inside the lab to find a product to prank or out of curiosity.
While holding a product with a strange rainbow color, they jumped as soon as they heard someone behind them and accidentally dropped the product on the person.
Kokushibo: What the hell are you doing..., Kokushibo looked for a moment at the product he had received and said to himself: I feel weird...

Daki and Douma were coughing because of the smoke and it was just then that Muzan arrived and saw the disaster.
Muzan swore: What is that!?
In a pile of kimonos was a baby Kokushibo!
