Well, here goes my another attempt at LoRA. This one is based on style of the mangaka Itosugi Masahiro (you can find him on MangaUpdates and on MAL). He is known for his ecchi and hentai works such as "Aki Sora", "Uwakoi", "Oneechan no Onegai" and many others.
I trained this LoRA on different black & white panels from "Aki Sora", "Uwakoi", "Kimikiss - Sweet Lips" and "Fragile". Total 100 pictures. Some panels were cleaned and edited to make training easier for neural network.
If you really want it, you can generate femboys. Itosugi Masahiro really likes putting them into his manga. Then you should use "otoko no ko" tag. For normal boys just use "1boy".
I advice using Illustrious version for Illustrious checkpoints (except new Illustrious versions 1.0+, for them you should you NoobAI-XL version).
Attention!
0) Preferable strength is between 0.8 - 1.3 (depends on checkpoint and other LORAs used in generation).
For Pony I recommend using strength of 0.9.
For illustrious I recommend using strength of 1.1
For NoobAL-XL I recommend using strength of 1.0
1) No additional tags needed for using this LoRA. Just add and it's ready to go.
2) It displays artist's style even with score and quality tags. But without quality positives the result'll be more like artist's style.
3) As my testing shows, this LoRA works with every checkpoint. If you want to use this LoRA on other checkpoints, then you should adjust the weight of this LoRA (0.9 or 1.0 is good enough for most cases).
4) Yes, you can use it to generate hentai images on Civitai.
5) This mangaka likes, no, he LOVES drawing quite long necks.
For negatives I recommend adding "jpeg artifacts" tag.
