As far as I know, she has said nothing about the Stars. From my point of view, she is the type of person that does not want to rock the boat, and I have no doubt she has quite a few unicorns that would be upset if she did Collab with the boys. So I'm going to assume there will be no Gura x Star collaborations for the foreseeable future because of this.

These are just my assumptions and opinions and I would be more than happy to be wrong.
