I was surprised that I enjoyed this. While there were definitely parts where it was disturbing, they fit with the her character. The protagonist has little impact from the 50 chapters that I have read; of course the focus is on the her so it makes sense. The translation was pretty good, I didn't notice any blatant errors (or at least I don't remember any). This is an adult manga but I would consider the BDSM or the torture parts to be the main point that would turn people off; or the lackluster protagonist but I didn't really mind him.
