The kind of girl that does nothing without a gang surrounding/backing her (be it the Lucky Seven armed with slingshots and rocks, or a powerful organization armed with sniper rifles).
The mouse girl was mouthy until she knew the police/interventionists were on the way to back her, then her image got tougher than nails and the violent threats started coming from her whole posse.
