although not sexual violence itself, his mother is tortured and burned like a witch, he meets 3 spirits, a father and his 2 daughters that were raped and burned to death by bandits, a Ghoul girl is being hunted and is almost raped until she is saved, a human girl was sold by her father, turned into a prostitute/slave, fled and was abducted by Ghouls.
3 of these cases are shown just as background story, as he only meets them after the events already happened, the only exception is the 3rd one, as MC himself rescued her just before it happened.
The summary may seem heavy and negative, but the story has an overall very positive tone. You can read without being bothered by excessive violence.
