^From what I understand, the suffix "-ko" is generally considered feminine. The Qs apparently have a "thing" where they sometimes refer to each other or themselves using a feminine version of their name (sans Saiko). The only one I can't remember off the top of my head is Shirazu, but as for the others:

Mutsuki = Mutsuko

Sasaki = Sasako

Urie = Uriko

It's like having a guy friend called Peter or Alexander and teasing them by calling them Petra or Alexandra.
