The Inciting Demon was surprised when the woman ran towards it, but it wasn't deterred. The plan was still the same.
After they both dodged another one of Clayton's swings, the woman shot. The bullet hit the Inciting Demon in its "chest." It stumbled away, and after a few seconds of deliberation, went to hide behind a tree. Although it possessed regeneration, it was nowhere near as good as Clayton's. Its regeneration was slowing considerably. If it took anymore significant damage from the woman, the threat of death was much more imminent.
Clayton hadn't seen the Inciting Demon go behind the tree, so he had his sights set on the woman again.
