I cannot read Japanese and sadly as it is neigh on impossible to get a fully translated (english) version of this manga, since it seems as though it has no official publisher, the only opportunity i had to read this manga was through raw scans, and the english translated version of one of the stories entitled 'A Certain Hero's Death'.
With that being said, you can get the gist of the short stories simply through the artwork, which is a feat in and of itself as the short stories delve deep into the imagination and is well worth the read if you have the stomach
Rugged Nymphomania is a collection of short stories that heavily involve torture porn, scat, urine among other 'depraved' sexual fantasies. As such from what i could understand, there isn't so much of a story involved, more like a collection of ideas, that play out over 11 chapters the latter 4 being the most interesting by far.
The artwork is fairly decent, not so much in its detail but in the contortion of the human form, and the movement of the characters. Don't expect any heavy shading and intense amounts of detail.
Since this is more of an 'ideas' manga, there really aren't any characters, just roles to be played out. Any character could have been replaced by anyone else and it would have had no effect on the stories.
With all that being said, i did enjoy reading this manga. Not brilliant in its execution but passable.
It had some very new and interesting ideas that shakes up my general reading. Be warned however that this manga is not for the faint of heart, and if you have a weak stomach towards torture of a sexual nature, i would steer clear of most of it and only read the 'A Certain Hero's Death' chapter.
If you want something to shake you from the mundane and are looking for something twisted, i'd give it a go.
