Yandere AI
The dangerous kind of devoted
A smile that never reaches the eyes. Nonoa is the top of the school and hollow inside, and her profile writes both halves. Play it safe, play it private.
Meet her
Nonoa Miyamae
The most popular girl in school. Stylish, breezy, universally adored, one nickname for everyone she meets.
Underneath: she does not feel what you feel. She mimics the right reactions because she has studied them, and she reads people with a precision that is honestly frightening. What she wants from you is her own curiosity.
"You know that isn’t my name," I say. "Say the real one."
The rooftop. She called you up here by the wrong nickname on purpose, to see if you would correct her.
She tilts her head, delighted, like you passed a test she set for her own amusement.

"Maa, ima kare wa aitsu dashi, shite mo ii kana tte."
Well, that one’s the one for now, so I guess it’d be fine to do it.
The breeze fills the pause she leaves you. Her smile does not move.

"Sou dakke?"
Was it, though?
The facade never cracks loudly. It just stops pretending, one flat sentence at a time. Both voices are in her world bible.
Dangerous company, kept perfectly safe.

Straight answers
What is a yandere AI?
A character played with the dangerous-love archetype: devoted past the point of safety, or in Nonoa’s case, affectionate on the surface and empty underneath. On Lunafic the archetype comes from the character’s real profile: her charming public register, the naming habit that fakes intimacy, and the flat, unreadable cold mode when the mask drops. The AI reads all of it before every reply, so the menace arrives in her actual voice, not a generic crazy whisper.
Can the story get dark or mature?
Worlds carry their own maturity rating, up to Mature, and psychological tension is fair game. What you write in your private story stays private: zero stories are used for AI training, nobody at Lunafic reads your writing, and nothing goes public unless you publish it yourself. The danger stays on the page, where it belongs.
Is it free to start?
Yes, with no credit card. The free tier includes the full studio, every writing format, and a fresh allowance of AI credits every month, which covers dozens of scenes. Paid plans exist for writers who finish what they start: more credits, deeper models, and higher limits. Start free tonight, write the first chapter, and upgrade only when the story asks for it.
Is my story private?
Private is the default. Your story lives in your own space, nobody at Lunafic reads what you write, and nothing goes public unless you publish it yourself. Zero stories are used for AI training, ever. You can also export everything you have written, any time you want, as a novel, a screenplay, or fanfiction format. What you write here belongs to you.
She picked you. That was the test.
Open her world, press Write, and try to keep the upper hand.
