Muzan: "This is my daughter, take good care" he said in a threatening tone with sharp eyes, then disappeared

Akaza: "Wft? Mr. Muzan has a daughter!???" He was shocked when he heard Mr. Muzan's words, his eyes widened as he looked at her

Douma: "Eh~ Mr. Muzan really has a daughter~" he looks at her half-believingly

Kokushibo: "..." he is equally shocked, but always has a calm demeanor
