Violated Heroine, Pink Pencil for consensual stuff (at least I
think it's consensual? Mostly just bizarre, like "Monty Python trying to get banned for obscenity" levels of weird),
The Hunter (also consensual, and incomplete),
Stationmaster with "extreme content" enabled (beyond the setting mostly implied/in text, visuals fairly vanilla)
At least those are the ones I would not expect to pop up on a guro/ryona search which should cover all your blood and graphic violence needs.
