Yes there is a lot of sexual violence. Not in pornographic detail, but otherwise it doesn't hold back much. I'm rereading right now, on chapter 25, and at least two different characters have been raped (and murdered, IIRC).
To people asking about the missing chapters, this series has never been scanlated before chapter 120 (the early 90s). What you find online are ripped official chapters. They will never be uploaded here.
The digital copy goes on sale two times a year. I got the whole series (31 volumes) for 100$ on new years. Just add it on your wishlist on Amazon or Dark Horse website, you'll get a notification when the sale is up.
For the record: The English version is really good, especially that author had a hand in it with the redrawing handled by him.
