In case if you are interested...
I released Anisnuff, a finetuned Anima for R-18G scenes.

Sample images:

Setup:
Just copy diffusion_models and lora folders to your ComfyUI.
Use the default VAE and text encoder for Anima.
Drop any of the workflow file and enjoy.

Note:
- I have not fully explored the possibility of Anisnuff_v15. You will certainly create better images.
- I recommend using natural sentences for the prompt. I have not tested with danbooru tags.
- Avoid "splatter" in the prompt. It is strongly linked to American comic art style in the Anima's dictionary.
- LoRAs (helper loras) are not necessary but sometimes useful.
- IMPORTANT: Don't use it for offending real people.
- IMPORTANT: Avoid mimicking the style of a specific artist.

If you want thank me, then you should spend some money to R-18G artists.

Major categories in the training data (That means it has a chance to generate such scenes):
Arrowed, beheading, choking (by hands), damaged body, damaged head, devoured by creature, digestion scenes, drowned, femdom scenes, hanging, impaled, rotten corpse, neck snap, parasites, punched, gunshot, stabbed, strangling (by string), eaten by dogs, eaten by rats, skeletons, stripped to display, peeing self, implied erection, some humiliation scenes, some nudity scenes, some sex scenes (conventional & non-conventional), some uniforms (police & military), some tactical equipment, beautiful scenery

Future plan:
- In 1~2 weeks, I am going to add more workflows which help to generate more diverse R-18G scenes.
- In 1~2 months, I am planning to do another training toward Anisnuff_v16.
- In ???, maybe I try the base model other than Anima.
