Ren Yamashiro, commander of the 10th Unit from Mato Seihei no Slave (Demon Slave), in a realistic photographic style, for Krea 2.
She is an adult woman in her twenties with long straight dark purple hair, blunt bangs, vivid violet eyes and a red knotted cord hair ornament with a long tassel. Face and ornament are carried by the trigger.
Trigger word: rnmshr_perso
Recommended settings
LoRA weight: 0.8
8 steps, CFG 1, euler / simple (turbo-style Krea 2 checkpoints)
Best on Krea 2 turbo and CyberRealistic Krea 2 v4, which keep her hair color and likeness. Satori, Moody and Utopic World are usable with the uniform, but her hair drifts to black in other outfits. Avoid BSS Desire: her face comes out far too young.
Prompting tips
Always say she is an adult:
an adult woman in her twenties, adult face.Keep the hair in the prompt:
long straight dark purple hair with blunt bangs, vivid violet eyes. The hair ornament comes with the trigger, no need to prompt it.Her uniform:
wearing a black military-style uniform with gold epaulets, gold braided cords, a brown leather belt, a red cape and white gloves.Other outfits are fully promptable (kimono, streetwear, evening gowns...). Light knitwear can show odd marks at the chest: darker or thicker fabrics work better.
