[She's hardly the best choice for dealing with monsters, lacking any magic whatsoever. But if she knows there's a risk, she has to make sure nobody else goes wandering off. NEVER FORGIVE, NEVER FORGET THE WHOLE SHRINE DEBACLE, FAM...
In any case, Chloe's spending most of the day setting up signs and warnings for high-risk areas. Her gun's loaded and she's ready to subdue anything that might pop out at her, although obviously she'll only be able to handle the smaller of creatures, nothing too big. She'll send more powerful magic users later once she has an idea of the area.
IN ANY CASE, she is also actively searching to make sure nobody does the dumb thing and try to enter these areas, or worse, accidentally wander in and not realize. :| All you losers behave.]
