The Kirihaya's told the boy, "You should still stay around, it's dangerous out" before operating on the young fox girl. Considering that the girl was not healing well, they looked for the wound in her back. "We are going to put you to sleep okay? Just relax and breath in." They told the girl, putting on a mask for the girl, to put her to sleep. Once she was asleep, they started to operate, opening the wound and tweezing out the Varanium shrapnel in her back, cleaning the wound, and treating the area with some antibiotics, before stitching her up and taking off her gas mask.
"Well that should do. She should heal now."
Yuki ran and ran, going around corners and preparing to deflect bullets. From time to time, a stray bullet scrapped her, cracking part of her shell/skin. She continued, however, to run. Inside of her body, chemicals stored, building up. She was mixing a low boiling point, highly potent sleeping gas, to release all around.
Finally, after having been on the run for probably an hour or so, she stopped, her back opening up, and releasing all of the chemical she had been storing. As it boiled off, it dispersed and looked invisible and scentless. As the mob came rushing towards her, they started to feel weary and started to fall asleep on the streets. It wasn't long for all of them to start sleeping.
"Well, I should head home" the girl hidden by her ninja-like clothes thought to herself, running off, departing from the city and heading towards her home. "I'll be back soon." she spoke into the ear piece, indicating that she was on her way home.
