Sumire started off as an JAV actress back in 2016 (under Miri Mizuki), but had very recently went into OnlyFans as well. Having a slightly tanned skin tone, Sumire is easily recognisable among the crowd of AV actresses. Similar to Akari Niimura in many ways, Sumire has a fairly petite and muscular built, but probably much slimmer. Due to her sick action, she is commonly known to be one of the best "cowgirls" - well, see for yourself. Since it was brought up a few times that most Asian checkpoints cannot render non-East Asian skin tones well, so I had to try it out myself with this LoRA.
variations: parted lips, lipstick, lip gloss, blush, thick makeup
Use of prompts depend on checkpoints, use it if your checkpoint have a bias towards minimal makeup.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Checkpoints that work well for this LoRA:
1) Realisian/RealisticMix. Its a close-tie.
Realisian gives a better overall render, with her body physique modelled accurately, but with a lower tan.
Meanwhile, RealisticMix does a better render for her face and expression, but can over-react on skin tone prompts (dark skin). And higher probability of badHands.
2) UltimateHentai Realistic. Very similar to (1), just that the render over-smooth features (i.e. makes her too young).
3) GrayColorSemiReal-mix and ClearRealism-mix. Good models to render the slightly darker skin tone, but sometimes it goes overboard.
4) PerfectWorld. Technically workable, but performance dropped once you start to add clothing prompts.

Note for achieving good resemblance:
To achieve good resemblance, you need to get Sumire's tone correctly.
There's no golden rule, since each checkpoint weight skin tone prompts differently, so you will need to do a few trial-and-error.
I personally find using a skin-tone slider LoRA (like <lora:fstjq_Skin color adjuster> on civitai) useful if you dont want to use prompts like "dark skin", "dark-skinned female"
and LoRA weights tend to be more consistent for controlling tones as well.
Do note that if you set Sumire's LoRA weight too high, it does create some "tan" as well, but it is not advisable since this behaviour is less consistent compared to using a slider LoRA.
But remember, since Sumire is technically full Japanese, you will want to only partially tan her skin. (weight ~0.2 - 0.4). Then you can proceed to
1. Generate the main prompt using a LoRA strength of 0.7~0.8, higher for full body modes.
2. Supplement that by enabling face Adetailer, and set the weight slightly higher to 0.8. e.g.
"face of sumiremizukawa_jav, parted lips, thick makeup, long hair, dark skin, lipstick, <lora:JAV_sumire_mizukawa_v1_epoch_10:0.8>, <lora:fstjq_Skin color adjuster:0.4>"
The makeup prompts are optional, but can help create differential tone, which is common with girls (since makeup+blush to lighten the overall skin tone on the face)
It is still better to use AD at baseline generation (512,768 etc) and then upscale it later.
Recommended approach: is to not use HiRes, but upscale it with img2img instead.
Use a denoise strength of 0.25 -0.3 (anything higher will overcorrect face during the process), and turn off Adetailer.

Issues:
BadHands here and there. So far all generations produce Sumire with double eyelids, which is one of her more common apperance; but none have created her with the typical lazy eye expression. Hmmm...
Post-production edits/Reproducibility:
None.
Happy prompting. And do share [SFW] creations~
v1. Initial Release. Epoch 10.
Skin tone issue require tackling.
Maybe re-train in the future, with more data.
