Yandere AI
The dangerous kind of devoted
A warm voice that never lets go. Captain Vance would do anything to keep Akari safe, and his character sheet writes both the warmth and the danger. Play it safe, play it private.
Meet him
Captain Vance
A veteran homicide captain, the boss every junior detective wants. Easy charm, fatherly warmth, always willing to take the heat from the top brass.
Underneath, a suffocating, possessive devotion to Akari, the detective he raised. To keep her safe and rising, he has already crossed lines nobody knows about.
"Renn Kurosawa," I say, and hold up the file. "I think he was telling the truth."
The archives, late at night. You are Akari, digging into old case file A-14, when Captain Vance appears in the doorway.
The warmth drains out of his voice.

"Nani? ...Kurosawa Ren, da to? ...Naze ima sara ano otoko no namae ga derun da."
What? ...Ren Kurosawa, you said? ...Why is that man's name coming up now, of all times?
He steps closer. Too close.

devotion and danger in one line, a real Speech Example
"Akari... onegai da kara, kore ijyou fumi-komu na. ...Omae wo ushinaitaku nai n da yo. Ore wa... sore dake wa taerarenai."
Akari... please, don't dig any deeper. ...I don't want to lose you. That's the one thing I can't bear.
The warm boss and the man who would burn the department down to protect her. Both voices are in his character sheet.
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. On Lunafic the archetype comes from the character's real sheet. Captain Vance's Personality panel describes a possessive devotion he hides behind fatherly warmth, and his Speech Style has two registers, the soft one he uses alone with Akari and the cold one when anyone gets close to the truth. The AI reads all of it before every reply, so the menace arrives in his actual voice, not a generic crazy whisper.
Can the story get dark or mature?
Yes, within two lines. Psychological tension, dark themes, and mature romance are fair game when the story leads there, and the AI refuses anything involving underage characters, so every character must be an adult. Published worlds stay mature but never explicit in their title, pitch, or pictures. What you write stays private, zero stories are used for AI training, nobody at Lunafic reads your writing, and nothing goes public unless you publish it yourself.
Is it free to start?
Yes, with no credit card required, and stories are unlimited on every plan. Free plays on the Flash model with a monthly amount of AI usage, which is enough to open a world and play your first chapters. Paid plans add more AI usage every month, the Standard and Pro models, and open the Memory dialog, search, and Find and Replace. Start free tonight and upgrade only when your 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 choose to publish it. Zero stories are used for AI training, ever. In your own private world you can also export your chapters anytime. What you create here belongs to you.
