tf is Yuri in the first place?

Again your wrong as the books focus is being reincarnated in the world we know as Naruto as if it was the REAL world as explained above and while pitiful and mildly to largely disturbing r*pe during conflicts based on history of humanity seems to be part of our nature after all as the most basic truth is human's despite our awareness of self and our morality are animals

First you've obviously haven't written anything from mid first person view, and second this is a story about a person reincarnated into a NEW world without any preexisting knowledge of said world so your reference to anything plot based is null as the point of MFPV writing is to make it seem like your following the protagonist as a "guardian angel" of sorts as the tease/foreshadowing is to correlate and your emotions to match what the character is feeling or thinking. Third your problem with r*pe is unjustified solely as I've said before MFPV writing puts you as an accompaniment to the character in a REAL world and your basing your knowledge of warfare on MODERN perception which btw is still screwed as it does happen even today it's just not publicized also it's punished after the establishment of the United nation less than a century ago after ww2. look at human history without your children's filter on and every war or battle in a pre-industrial era was marked by the slaughter or enslavement of the loser of battle and yes all posts or villages occupied by a party (military mercenary or bandit) where they had stay an indefinite or brief stay they used the women as tools to sate their men's lust and stroke the satisfaction of their ego so they were more willing to follow orders and remain on alert as it was simpler and safer than bored or intoxicated troops
