Roux's eyes narrowed in on Nero "You again....I had it under control..." she spoke, clutching her Keyblade as she looked at the dragon, who in turn, was still unphased by Nero's attack, only causing it to roar and get even more angry, to which it begun to bite down on Nero.
Roux on the other hand, just watched the dragon take on Nero, her eyes still glaring at him and what he had done earlier on with her. She sighed a little bit, putting her other hand on the Kayblade, bringing it backwards, the tip of it aimed at the dragon and second later, she fired a few shots of darkness at the dragon.
The shots realed in, zooming past Nero's head and blasted the dragon in multiple places, to which Roux contiunued to shoot at the dragon, contiuing to shoot darkness shots at the dragon as she remained where she was.
The dragon roared as its attention turned back to Roux as it swiped its tail against a nearby chimney, sending it flying at Roux, to which she had to stop what she was doing and ducked down as the chimney flew over her head and struck the ground in the marketplace.
