Maia was glad she wasn't being left behind, though really she was more distracted by the strange and lovely weapon the girl had, two of the peices even being handed off to her to cover their retreat. Thankfully they were not that hard to get a hang of, more so for someone like her. Using the gun to hold them off rather well, given that she did not want those things anywhere near her, more so since she couldn't really fight close up while being held like that. Zooming out of the cave Maia was put onto the ground, leaving her to support herself but with her tail wrapping around her waist she was able to join in picking off the surviving Grimm from the act of blowing up the cave. 

"Heh... I wonder if this makes us advanced" 

She joked more to herself before handing off the weapons to the girl and being told off for going into the caves... Looking back to Regi for a moment she looked to the girl and smiled. "Yeah, I got a little cocky, thankfully Regi came to help me" She said, straightening up, the pain turning from a burning to just a slight pain.
