(note: tag says manga which it isn’t although that’s the closest category I could find)
I stumbled across this on YouTube where it’s been uploaded with narration. I took a look and Ho Lee Phuk! Cute little humanimals being hideously butchered by serial killers. Not for the easily triggered. Granted it’s clever in both story and execution (no pun intended); but it’s the sort of novel that makes you wonder if it got the author investigated by the police.
One of the YouTube comments claimed that they’d seen this for sale in the children’s comics section of a store.
I shared a post about the fortieth anniversary of the animated film Orrin- Legend Of The Starchaser. I was stunned to see that the poster advertised it as ‘for the entire family’. I do not remember any sex or nudity in the movie. Some of the film is too frightening for kids. There is a lot of graphic violence. It is very much not a film for the entire family.
It is a good movie though. I saw it in the theater. I rented it at an independent video store. The owner had placed in the children’s section. I advised him that it did not belong there.
I’ve browsed through the comic without reading it, and I wouldn’t rate it as even close to “nightmarishly gruesome”. It is actually pretty mild as horror comics/manga go. I think your perception is being distorted by the “but it’s cute animals!” factor.
