Someone that claims to be an agent of change, here to displace anything that was already there or always there. Out with the old, in with the new seems to be their go to motto, though really they hold nothing new sacred either. Someone like that would try and side with the majority even if the new guard was forced out by the old guard.
The girl that thought she was the new guard would try and replace everything people loved about the place with her own image, that way people would love her, all their love would go to her.
