I think guro is weird and if you jerk off to it you should be beaten but for basically curosity reasons i'm trying to find something guro related. The series is called "Lady in the sea of blood", a series consisting of six entries and one anime.
The company that made it seems just to make low bar fetish content, guro, extreme bondage and other things in the vain. The only one found is the second one and i think the third one as well, and a snippit of the third one.
Below is the everything from the second one containing info, so do what you will with it.
Distributed by: Film Corps\Dream film corp (電影軍団/夢幻電影軍団) Seems wierd for a company of such niche porn to have such a basic name, personally i think maybe they might be a branch of a more pedestrian JAV company.
Created by:The hall Of Life and Death(生死堂)
Directed By: Takeshi Okimoto (沖本猛)
Actress: Maki Sawada (沢田麻紀)
I have no info on any of the cast or the rest of the creators, but in the end credits there is more names i assume mostly other production companys and most importantly a phone number. here is a link to the movie. It contains no hardcore stuff besides a chick covering herself in fake blood whild nude, which is really low qaulity.
