If it follows the manga, and it probably will since Yu Aida is basically in charge of the writing for the 2nd season, don't expect Triela to somehow provide a 'role model' for feminists... Although she plays the perpetual tough girl, in her arc, her actions reveal that ultimately, her raison d'etre is to gain acceptance from Victor, and despite his wariness around her/fear of her, he eventually comes to terms with that.
