This is a concept LORA involving a character being shown, but with a shadow-like appearance and glowing eyes. The concept has been trained by the artist Baaki. I'm not sure what to call this specific fetish, but I really like it and I don't really see much artist tackle this specific niche. If anyone has a better name for this concept or know what it's called then let me know and I'll change the title lol. The artist mainly drew their characters with female gyaru and ganguro girls, so it'll probably work best with that specific character type. Using this LORA in sexual acts can work, but it's mainly focused on solo character generations.

Positive Prompts: SFRBaaki, shadowy figure, shadow face, shadow, dark, glowing eyes, no pupils

For the eyes you can just choose whatever color you want and it should work.

For a different effect put "pink background, pink aura." And for better results put stuff like "big breasts, big butt" since the LORA is trained with that specific body type. Also try and to not describe the character's face for a better effect and put stuff in the negative prompts like "mouth, nose, nostrils, eyebrows" to help with the LORA. You can describe the character's hair though that'll work fine. I've also tested showing the LORA with teeth in one of my featured image examples if you want to see how that turned out. The LORA's weight is a bit hard to pinpoint because if you do it too high, then it'll generate stuff on a character's body you didn't ask for mainly being tattoos. And if you do it too low, then the effect won't happen. Use my image examples and prompts to see how to trigger it if you need help on that.

Finally, you can add "silhouette" if you need the body covered completely shadowed.
