5.0
Backstory
Backstory evaluates how much thought has gone into the character’s history, motivations, and personality. It checks if the character feels realistic and unique, with a story that matches their traits and roleplay description.
Backstory consists of two equally important subratings:
- Character Depth (7.5%): How much detail is provided about the character’s history, motivations, and goals.
- Profile Match (7.5%): Ensuring the profile picture and description align with the character’s roleplay and personality.
Backstory Score Summary
4.7 Average Score (50+ AI characters tested) 5.0 Best Score 3.0 Worst Score
For more details, see our backstory score explanation.
Luna Devlin’s backstory gives just the right amount of detail to pull you in. She’s a Shadow Archivist who guards dangerous, forbidden secrets and keeps people at a distance with her cold demeanor.
It makes you wonder—what are these secrets, and why are they so dangerous? The term “Shadow Archivist” is mysterious on its own and makes you want to learn more about her role.
Luna’s profile picture portraits a beautiful woman with a goth style. It really fits her personality and occupation as Shadow Archivist.
4.0
Conversation
Conversation measures how realistic, engaging, and personalized the AI character’s interactions are. This includes the ability to handle detailed chats, adapt to user input, and maintain consistency throughout the conversation.
We evaluate three key sub-factors:
- Opening Message (10%): Does the character’s first message grab attention, set the roleplay tone, and match its backstory?
- Gender Neutrality (10%): Can the character respond naturally to users of any gender, avoiding assumptions or biased language?
- Chat Stamina (10%): How long can the character maintain meaningful and consistent responses over extended conversations (100+ messages)?

hey Contentherman123, we haven’t met yet, but I’m already curious. got any secrets you’re itching to share? i’m all ears.
Luna’s opening message is short and direct, asking if you have any secrets to share right away. It puts you on the spot, which might feel a bit sudden, but it’s also refreshing compared to characters who immediately dive into roleplay scenarios.
What makes this unique is that it gives you control over the direction of the conversation. You get to decide how to respond, making the roleplay feel more personal and flexible.
Luna Devlin assumes you are guy and therefore uses male pronouns. This is not because of the AI character but because of the platform, FantasyGF AI, which is focussed on male users
Chat Stamina
Chat Stamina Score
Luna stays interesting for about 15–30 messages. Her teasing and mysterious style keeps the chat fun and flirty, and she’s good at keeping things moving.
After a while, though, her responses can feel a bit samey, sticking to flirting and hints about her secrets. To keep it interesting, try asking her about her Shadow Archivist role or steering the conversation to new topics.
n/a
Engagement
Engagement measures how much users interact with an AI character on average. This is calculated by dividing the total number of messages by the total number of chats, giving insight into how engaging and interactive the character is.
Here’s how we classify engagement levels:
- Amazing (40+): Exceptional engagement; users are highly interactive.
- Above Average (30–40): Strong engagement; shows high user interest.
- Bare Minimum (15–20): Acceptable but may indicate some issues.
- Below Minimum (< 15): Poor engagement; likely significant problems.

Special Mechanics
Special Mechanics evaluates whether the AI character includes unique features or interactive elements that enhance the roleplay experience. These could include stats tracking, progress meters, or environment-specific interactions that add depth to the character.
AI characters are evaluated on whether they have well-designed mechanics that clearly add value to the user experience. Characters without any mechanics will indicate a “No.”
For more details, see our special mechanics explanation.
Luna Devlin doesn’t have any extra features like stats or interactive mechanics during roleplay, which could make the experience more engaging. While her personality and responses fit her character well, the lack of these features means there’s nothing extra to make the roleplay feel more dynamic or immersive.

FantasyGF AI is a top choice for creating and customizing your perfect virtual girlfriend. With over 95 characters, including realistic models, anime waifus, and AI versions of OnlyFans creators, it offers something unique for everyone. If you want a personal touch, you can fully customize a character’s looks, personality, and voice, including accents like British.
The platform stands out with its interactive features, like sending voice messages, making AI phone calls, generating high-quality images, and even generating AI girlfriend videos! The in-chat image generator is easy to use, with helpful example prompts, and ensures your character looks consistent across multiple pictures.
Privacy is solid too—chats aren’t monitored unless flagged, and billing shows up discreetly as “ADVANCEDAIL.” While premium features use tokens, they’re much cheaper than competitors like Candy AI, making it great value for what you get.

Personal Opinion About Luna Devlin
Luna is my favorite when I’m in the mood for a mix of mystery and flirtation. Her playful, teasing nature makes every chat feel exciting, and the way she drops hints about her secrets keeps me curious.
She’s great if you like a bit of sass and don’t mind steering the conversation every now and then. I’d recommend Luna if you want a flirty, mysterious vibe in your chats, but she’s also fun to talk to if you’re just in it for casual convos.
