Source: Villainess Level 99: I May Be the Hidden Boss but I'm Not the Demon Lord (Akuyaku Reijou Level 99: Watashi wa Ura-Boss desu ga Maou de wa Arimasen)

Character Description:
Yumiella Dolkness is the stoic, level-capped protagonist known for her overwhelming dark magic and misunderstood "Hidden Boss" status. She is defined by her striking long black hair—a rarity in her world—and intense black eyes that often carry a calm, expressionless or deadpan look. Despite her world-breaking power, her style is typically formal and understated, favoring her academy school uniform or a crisp white shirt accented with a signature red ribbon or neck ribbon. Whether she is holding her magical staff, relaxing in pajamas with her pet dragon, or quietly drinking from a teacup, Yumiella maintains an aura of detached, monochromatic elegance.

⚙️ Recommended Settings & Tips

• LoRA Weight: 0.85 - 1.0 (The deep black hair and black eyes are her most important anchors; high weights prevent the hair from shifting into dark brown or blue).
• Base Models: Optimized for Illustrious XL and Pony Diffusion V6 XL.
• The "Yumiella" Stare: To capture her personality accurately, always use expressionless or deadpan. If her expression is too lively, it won't feel like the "Hidden Boss."
• Pro-Tip: Since her design is monochromatic, adding red ribbon provides a crucial pop of color. For backgrounds, magic circles or dark energy can be added to showcase her Level 99 status.
