Well, I've been playing this game for a days and made a few "re-runs" while I tried to get used to the gameplay, figure out a playstyle for me, etc.
Today, I started to give girls the "Security" order; normally I didn't have much trouble with customers raping my girls or the like (and those few times it happened, I simply re-loaded the autosave), but I figure it was "in-theme", so to speak, and assigned two of the more combat-capable girls this duty, which lead me to two observations.
One, it seems that having girls on security duty actually attracts rapists and the like.
Two, despite good equipment and combat stats, the security girls are always overcome.
Since putting those two girls on duty, I've had an "incident" pretty much every turn, reloading or not, where those girls were overwhelmed by their attackers and one or two of my other girls being raped.
Likewise, when I assign a girl to explore the catacombs, she almost always ends up defeated and abused by monsters.
Which is another thing that strikes me as odd; the girls I pic for this role have 100% combat stat, at least two of the combat-strengthening traits (strong, adventurer, assassin), and the best equipment I can buy at the shop (plate mail&boots, ceremonial saber), and despite that they lose far more often than not.
