All of Andrew's wives and guardians were in the office, so upon hearing the name "Fluffy," they immediately knew who she was. While it was true that they had never seen her, they all knew her.
Since they received the seal of wives or guardians, they learned many secrets from Andrew, but the fact that he had a divine beast was not among them.
Andrew told This secret directly to them, as he had perfect trust in them. They did not know what they looked like and most of their functions, but they understood that she was Andrew's closest companion.
Still, they were surprised that the divine beast that Andrew called "Fluffy" was a beautiful woman like the one they were seeing. Little did they understand how she could have a name like that, looking like that.
What they did not know was that when Andrew first met her, she was a small cotton ball and that was why he gave her that name, it was nothing compared to what they were seeing right now.
