JAV Mika_Kayama

Imitation model. Modelled after retired Japanese gravure model and AV star Mika Kayama (佳山三花).

OK, many of you probably won't know this one. Mika Kayama's debut in AV is fairly short-lived, having started as a gravure model in ~2002 under the alisa of Arisa Oda (小田有紗), and only joined the JAV industry for 4 years before retiring in 2011. Some of her work and appearance do leave an impression among fans, especially those that follow the early days of JAV company s1 very closely. I personally find her petite physique and square-ish facial structure within a mature JAV genre quite unique, hence this model.

~~~~~~~~~~~~~~~~~~~~~~~~~~
Recommended LoRA strength: 0.6 (0.5-1.0 are plausible range dependent on checkpoints; higher values changes the shape of the face and enlarges the chin..; use the high weights for Adetailer instead)

Main Prompt:

mikakayama_jav, breasts, brown eyes, jewelry, long hair

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

facial variations: parted lips, lipstick, lip gloss, blush

*Use of facial prompts depend on checkpoints, use it if your checkpoint have a bias towards minimal makeup, most of the time you wont need any of these

Checkpoints that work well for this LoRA:

1) Realisian/RealisticMix. Back to the almost-perfect duo. I dont even need to cherry-pick, most pictures are quite on-point.

2) PerfectWorld and UltimateHentai My only complaint is the more 2.5D style render. Nothing major.

3) Other Asian-based photorealistic models. Only tried those, doesnt sway too far. Technically even merged models like GrayColorSemiReal-mix and ClearRealism-mix works well too.

Note for achieving good resemblance:

This LoRA is easy when it comes to reproducing good resemblance. 2 Steps:

1. Generate the main prompt using a LoRA strength of 0.6~0.7, 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 mikakayama_jav, long hair, brown eyes, parted lips, lipstick, <lora:JAV_mika_kayama_v1_epoch_8:0.8>"

The makeup prompts are optional, but can help create a more "mature female" appearance, if you wish.

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 mainly. Nothing major.

Post-production edits/Reproducibility:

Minor inpainting on some Badhands, and clothing.

Happy prompting. And do share [SFW] creations~
