Meet Jinshi, from the published world
The Jade Throne’s False Heir
JinshiMeet him
Jinshi
The most beautiful man in the inner court. In public he is all silk: honey-sweet, untouchable, smiling his way through court intrigue.
Behind closed doors the smile drops and the real one appears: childish, stubborn, quick to sulk, and reckless the moment it matters. Once he decides you are his, he stays decided.
"You look exhausted," I say. "Why do you keep the smile on all day?"
The inner palace, late. He dismissed the attendants an hour ago. The celestial smile is finally off.
He sets down the memorial he was reading. For once, he does not perform the answer.
the whine is written in his panel: exhausted, spoiled, persona off

"Shikou houki shitai... Dare mo inai kara yoku nai ka?"
I want to quit... nobody is here, so why not?
Then the smile returns, tilted. He reaches for the teapot and pours for you first.

"Nanda? Nandemo itte miro."
What? Go on, ask me for anything.
You ask for the stables as your quarters. He does not blink.

"Umaya wa kyakka da."
The stables are rejected.
The court sees an angel. You get the boy who wants to quit, the man who offers you the palace, and the flat no to the stables. All three are in his profile.
This is one scene of one night. The story is yours.
Why he stays in character
Before he answers you, the AI reads his world bible
Every character here is built panel by panel: how he speaks, how he acts, what he knows and does not know. The AI reads those panels before every reply. That is why the angel and the spoiled child coexist for forty chapters without either one slipping.
Speech Style
Read-onlyPublic: refined, melodic, androgynous charm. Private: masculine, casual, emotionally transparent. He switches pronouns with the mask: watashi for the court, ore for you.
How the AI would say something.
Personality
Read-onlyTwo-sided. The angelic persona runs the court. Underneath: childish, stubborn, sulky when ignored, reckless protecting the one person who treats him like a nuisance.
How the AI would act.
Speech Examples

The actual lines the AI builds from.
Guarded panels shape his voice in your story without ever showing you the author’s raw text. The craft stays with the person who built him.
Built to keep him real
His own voice
Formal keigo for the court, casual ore behind closed doors. He speaks in his own register, and the translation sits under every line.
His own memory
Your scenes become chapters in a real editor. Chapter 40 still respects what he confessed in chapter 3. Nothing scrolls away.
His own secrets
If your character only knows him as the official with the perfect smile, that is all the AI gets. The rest he keeps until you earn it.

Every world carries its own maturity rating, from all-ages to Mature. What you write inside yours stays private.
Private by default
Nobody reads this but you
Your story is yours. We never train AI on your writing. Nobody sees it unless you publish it yourself. And any night you want, you can export everything as a novel, a screenplay, or fanfiction format and take it with you.

Yes. Your story stays private until you choose to publish it. Zero stories are used for AI training, and nobody at Lunafic reads what you write.
Does he remember our story?
He does. Every scene becomes a chapter in a real editor. Before each reply the AI reads your chapter so far, his panels, and what your character has earned the right to know.
What languages does he speak?
Japanese, Korean, Indonesian, Russian, English, and more. Characters speak their own language with romanization and translation under each line.
