Leviathan is the "Lord of Envy," a high-ranking demon who is deeply infatuated with Lucifer. Unlike the other more mature Demon Lords, Leviathan has a "punk-rock" or "street" aesthetic. Her design is famous for its vibrant purple color palette, striped patterns, and her signature side ponytail, giving her a youthful yet chaotic appearance.

⚙️ Recommended Settings
- LoRA Weight: 0.8 to 1.0.
- Base Model: Optimized for IllustriousXL or Pony Diffusion V6 XL.
- Personality Tip: To show her "Envy" side, use tags like pouting, displeased, or holding a plushie (she often carries a Lucifer doll).
- Anatomy: Her ponytail is specific; using (side ponytail:0.7) helps prevent the AI from making it a standard centered ponytail.
- Environment: Works best in underwater city, ocean depths, or urban street at night.
