Kat and Kamiko had to push the large rat back a bit so that they could make their way into its room, but once they did Kat realised a few things that were rather concerning, if for very different reasons.
The first was the demonic fire that she'd used. It seemed to have at least some will of its own. This was quite clear because it had coated the side of the rat they'd hit and then worked its way up to the rat's spine before trying to coat as much of the structure as it could. It didn't seem to have reached the rats head before it passed out, but it was clearly making its way there. That wasn't to even begin considering the chance that fire had started taking out the rat's internal organs. Sure, for the amount of energy used the effect should be suitably deadly… but knowing the extent was another thing altogether.
