the MC is actually older than she appears. Part of the plot and premise is that she got a body replacement (as in, her mind was actually placed within a body that was optimized for infiltration.). But I do agree that the institute doesn't do enough to prepare her for the job.The MC is a teenager, a virgin, who clearly has never had sex before. Currently too dumb and needs to go to school and relearn everything. Can't even defend herself against a school bully etc. etc. This goes a bit beyond of being "non-threatening", doesn't it? Sounds almost as if they want to use a child. And they clearly want to employ her as a "fuck toy", which I thought was quite clear from the Haven infiltration mission. As I said, something is really fucked up about this game's premise.
Or do anything to prepare her, really. I'd excuse it if they mostly had you running milk runs, but the haven infiltration is somewhat important to the groups survival as it mainly revolves around looking for a defector with a stolen artificial body with unknown motivations.
A virgin run is possible, and aside from getting money, isn't especially difficult.
