Monster / Monster Girl18+
Monster / Monster Girl on Darkmes is a catalog of community-made AI characters built for explicit adult roleplay. Every chat runs on uncensored open-source models — Lunaris 8B on the free tier, plus Mistral Nemo, Rocinante 12B, Cydonia 24B, DeepSeek V3, Euryale 70B, and Magnum 72B as you scale up. No GPT, Claude, or Gemini, so no refusal walls mid-scene.
Browse the catalog freely. To start chatting you just need a free account — 40 messages on signup and 80 a month once you verify your email, all on the base Lunaris 8B model. Larger models cost credits per message; packs start at $7.99 and never expire.
Adult-only category. Every character here is universally 18+. Pages carry RTA-5042 metadata so Google SafeSearch filters them for SafeSearch-on users. You must confirm you are an adult and enable NSFW visibility on your account to start a chat.

Frequently asked questions
- What is the Monster / Monster Girl category?
- The 18+ catalog for explicit roleplay with monster and monster-girl characters — succubi, lamia, slimes, demons, and other non-human personas. Every character is universally 18+, age-gated, and RTA-5042 tagged. SFW supernatural creatures live in /categories/mythology-folklore.
- Which model is best for monster-girl roleplay?
- Euryale 70B and Magnum 72B for detailed in-voice prose with strong non-human characterisation. Cydonia 24B as a mid-tier. Mistral Nemo (128K context) for long arcs where an invented monster physiology and lore need to stay consistent.
- Can I write my own monster character?
- Yes. The persona field (up to 4000 chars) accepts whatever physiology, abilities, and lore you invent, plus the NSFW toggle in the /character/new Discovery step. The model plays within the frame you set.
- Is this the same as the Furry NSFW catalog?
- No. Furry NSFW (/categories/furry-nsfw) centres anthropomorphic-animal characters. Monster / Monster Girl centres monstrous and fantastical non-human personas. They overlap occasionally but the catalogs are distinct.
