Tsundere AI
A tsundere who stays tsundere
Sharp tongue, soft heart, zero honesty on the first try. Euler Florence answers every kindness with a threat of "vengeance", and every register of her voice is written in her character sheet.
Meet her
Euler Florence
The heiress of a family the whole academy avoids. Her sharp tongue is a shield, and every kindness she gets goes into her notebook as a debt she has to repay.
Under the threats she is lonely, and she would sooner bite her tongue than admit it.
"Sono fukushuu, kekkou umai na." [This vengeance of yours tastes pretty good.]
The patisserie, on her "vengeance" outing. She forgot to hide how happy the cake makes her, and you noticed.
Her fork stops halfway.

"Ahh, mou! Nan de anata wa sou nan desu no?"
Ah, honestly! Why are you like this?
"Hmph... Kono urami, oboete oku wa!"
Hmph... I will remember this grudge!
She writes it down. Then, quieter, without looking up.

"Funn... nakanaka yaru janai. Demo, kore de katta to omowanaide ne."
Hmph... not bad. But don't think you've won with just this.
The deflection, a grudge for the notebook, and the almost-compliment. Three registers, all written in her character sheet before you ever said a word.
The tsundere arc is the whole point. Play it right.

What is a tsundere AI?
A character played with the full tsundere arc, harsh and deflecting on the surface, honest in tiny, reluctant bursts underneath. On Lunafic the archetype is written into the character's sheet panel by panel. Euler Florence, for example, answers every kindness with a threat of "vengeance", speaks formal Japanese with a sharp "Hmph", and her sheet says exactly how her voice drops when she is sincere. The AI reads all of it before every reply, so the thaw takes chapters, not messages.
Will she ever admit she likes me?
That is your story to earn. She only knows what your character has actually done, the kindness she noticed, the patience she did not expect, the promise you kept. There is no affection meter to game. Write the moments, and the small honest bursts arrive when they are deserved, in her voice, exactly the way she would say them. Her world even has endings to reach, and the warmest one takes the longest.
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.
She is not going to say it first.
Open her world, press Play, and give her a reason to almost be nice to you.
