Well as we can clearly see in the picture of the kwami's holder it's a girl and we probably all think Mr. Agreste is the butterfly miraculous holder. I have a theory that Mr. Natalie ( Mr. Agreste's assistant) is Duusu's holder because what if she found the the pin by accident. Plus her hair style is very like our new villain. This is my theory so I'm NOT CERTAIN OK! Hopefully I'm right though?.
