I went into this VN expecting something trashy, violent, edge and pornographic. What I got instead was a thoughtful, measured, genuinely deep exploration of all the facets of violence. There is still pornographic material that detracts from the general reading experience and dampens some moments but it's not enough to overcome the sheer quality in terms of the prose, dialog, themes, characters, and plot. I highly recommend just buying the Gog version and not bothering with the 18+ patch unless you're really morbidly curious about the content. I genuinely think a good half of those scenes are just bad and make the story worse. Also content warnings abound.
