This looks immediately better for me with the new girl. I don't hate the bunny girl, but this new one seems more interesting. The knight, or whatever he was, blaming the new musket girl for the hero killings was also a sign of a good plot. Now we don't know if it's really her or if the dude is just shifting the blame on her, with chances being he's in fact the killer. Either one would work for me. I'm also wondering if the extra hero (in the description, and likely meaning the hero killer) might not still be a hero after a fashion, only not chosen by the good gods to fight the demons, but by the demon king to fight the other humans.
