Reimu smiled as her plan worked.  She gave the imp a quick search; if he had any pouches or anything on his person she would just grab the whole pouch and stuff it in her own, planning to examine the contents later.  Now that there was only one imp still awake, she had a much better chance of not only winning a fight against the pack, but also possibly killing him without waking the others.  She would try to sneak a peek at the camp again, if the awake imp didn't wake any of the others yet, she would rush in and try to quickly kill him before he could raise any sort of alarm.  If he was waking up others however, she would look around for any other hiding spots that were a bit further away; hopefully if they spread out to search, she could pick them off one by one.
