Shio backed off of the mist immediately after seeing Kasumi's Mirror Image. She couldn't be absolutely certain if it was the real Kasumi or not. It would be unlikely given that Hydromancers operate more effectively within the mist, but she could not take the chance Kasumi was trying to make an aggressive play. Shio made sure she moved back, in a methodical backpedal style move, to keep track of both the core of the mist and the strafing illusion. By also angling away from both of them, moving opposite of the illusion, she could keep a wide scope of her vision free, as well as react to the both of the attacks from them effectively. She had an idea to combat Kasumi's tact of staying within the mist, but it needed time to be executed. Shio's Ocalia stayed with her, although quickly turning completely around and beginning to make a quick, wider movement to allow Shio to cover it while they both moved away. [6 Patience]
