Gorgon Sisters is a translated h-manga set in a generic fantasy world (defined by role playing standards). This volume continues the running theme of the sisters' bad sense of direction and tendency to get themselves raped in bad parts of town. Also like other volumes in the series, the main focus is on the story more than the sex.
In the first of the two stories, we're introduced to the third Gorgon sister. She's a "Black Magician" who apparently practices prostitution as a way of making money. She "volunteers" a young man for her services, and ends up getting more than she bargainned for. This story is probably the sexier of the two (in my opinion).
After this, the three sisters are reunited (Ciera the warrior and Maria the white wizard). A confusing flashback to how they got into this situation shows Ciera working as a mercenary, but getting into trouble when she confronts a gang of con men.
The second story involves a rather mean-spirited rape (much more serious than the previous volume did) that I didn't find as enjoying. Ciera is drugged and forced to comply against her will, despite her efforts to struggle.
The volume ends on a cliffhanger to be picked up in the next book.
Overall, the artwork is very good, but the rape scene in the second storyline is more disconcerting than the somewhat less serious scenes in the previous book. This series still doesn't win any awards for originality, but you could do worse.
