Imitation model. Modelled after retired Japanese AV star Riko Tachibana (立花里子).

Riko is considered one of the classic within post 2000' JAV, with the title of greatest lewd woman ("最強の痴女"). She used to be notoriously known for her performance in the BDSM, femdom, milf genres, popularizing the "prostitute JAV" concept, but her choreography is way more diverse than that. Notoriously known for her sharp boyish facial features (some netizens claim that she looks like a "horse.."), but with a slender body packing a toned abs, that marks her unique stage presence in the eyes of JAV fans. She retired in 2008.

~~~~~~~~~~~~~~~~~~~~~~~~~~
Recommended LoRA strength: 0.7 (0.6-0.9 are plausible range dependent on checkpoints; higher values amplifies facial features..)

Main Prompt:

rikotachibana_jav, breasts, brown hair, jewelry, long hair

variations: black eyes, black hair, tied hair, earrings

facial variations: parted lips, lipstick, defined cheekbones

*Use of facial prompts depend on checkpoints, use it if your checkpoint have a bias towards minimal makeup, most of the time you only need "defined cheekbones"

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Checkpoints that work well for this LoRA:

1) Realisian/PerfectWorld. Ok, depends on how you look at it:

For this one, PerfectWorld still provides a better render, when it comes to real-life resemblance; even though the features can be slightly over-exaggerated (but thats how Riko look like in real-life).

2) Realisian and RealisticMix both gives a smoother version of her, with a slightly less-sharp chin and more blended cheekbones. Because of that, she looks slightly younger.

3) MagicMix realistic. Facial wise, its ok. but you get slightly elongated body, and longer faces, which works for Riko (since she is of the slender-body type). Still a "close-enough" render.

4) UltimateHentai Realistic or other photoRealistic Hentai models Works adequately well 0.7 LoRA weight, but prone to some bad/weird generations occasionally.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Note for achieving good resemblance:

This LoRA requires very minimal makeup prompt, since her features are pretty easy to define. If I need to break this down, alot of what defines Akari is her:

1) Her parted lips expression.

2) Her eyes. She has the typical pheonix eye asian-feature, so any checkpoint that gives you bubbly FFVII type of eyes, might not work well.

3) Lipstick.

4) closed eyes. Yes, most of her gravure photos will show her with alot of expressions, and most of the time, with closed eyes.

You can either use facial ADetailer directly with no prompt, or use a facial prompt like the one below if you want her with some makeup. No rule here, get creative and play around.

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:

Nothing that needs immediate fixing, badHands, and occasional bad hand-body ratio. Just re-seed.

in img2img upscaling, sometimes the shape of her face can be alittle off as most upscaler try to smoothen her facial features - I guess you can try running Adetailer again with very low denoise to try and fix that.

Post-production edits/Reproducibility:

Minor inpainting on some Badhands, and clothing.

Happy prompting. And do share [SFW] creations~
