I was reading some horror manga called Freak Island and it's prequel Offal Island about a group of family mutant killers made by Masaya hokazono essentially a parody of Texas Chainsaw Massarce and The Hills have eyes with some supernatural vibe.
Masaya also made pumpkin Night about a teenage girl wanting revenge against her bullies and kill any bullies she sees.
Here are the pics
There is also killing Morph
Any good horror anime and manga you find to enjoy?
