# Mariabell Rosso (マリアベル・ロッゾ) A SFW character LoRA for Mariabell Rosso of Greed (〝強欲〟のマリアベル・ロッゾ / "gōyoku" no mariaberu rozzo) — the Saintess of Greed and Princess of the Kingdom of Siltrosso, from "That Time I Got Reincarnated as a Slime" (転生したらスライムだった件 / Tensei Shitara Slime Datta Ken / Tensura / TenSura / 転スラ). The granddaughter of Granbell Rosso and one of the Five Elders, Mariabell is a Reincarnated Otherworlder serving as a major antagonist in the Western Holy Church arc. She appears as a petite young girl with smooth blonde hair, choppy bangs, and signature pink/purple eyes — elegant on the surface, ruthlessly ambitious underneath, wielding the Unique Skill "Greed." This LoRA was trained on Illustrious base, optimized for flexibility across dark fantasy, modern, and atmospheric scenes. --- ## ⚠️ Content Notice — SFW Only This LoRA is intended for SFW use only.

Mariabell's canonical outfit features multiple decorative bows (on stockings, accents, etc.). Diffusion models struggle with exact counts and consistent placement — bows may appear, disappear, or shift between generations. Use explicit positional tags like <code>bow legwear, bow on stockings</code> and reinforce with <code>(bows:1.2)</code>. For critical shots, ADetailer or manual inpainting gives the best results. Medallion rendering issues. The signature medallion (green/silver floral cross design) is intricate and often comes out distorted, warped, or with simplified detail. The exact pattern is rarely reproduced 1:1. Illustrious NSFW priors. Base model has strong NSFW tendencies. Always use the recommended SFW-focused negative prompt above.
