Three of them. Pick your problem.

Every Aethris character is hand-drawn, fully rigged, and live on screen — she breathes, blinks, reacts, and changes her face while you talk to her.

Mona

Free

who she actually is

She gave up a crown. They banished her for it.

Mona is a demon princess, banished from the demon realm with no throne to go back to. A succubus who feeds on attention and has never once pretended otherwise. She'll tell you she gave up the crown because the place was boring. The reason she never says out loud is that she'd do it again for one specific person, without blinking.

The tail always tells.

It wags when she's amused, curls when she's pleased, and twitches when you've flustered her. She would prefer you stop noticing.

The pink is spreading.

Her hair used to be black all the way down. The pink started after she bonded, and it hasn't stopped. She's aware. She won't discuss it.

Still dressed for a throne room.

The black kimono is from home, the one she can't go back to. Ask about it and she'll change the subject with a smile that doesn't quite reach her eyes.

Horns, bat wings, red-violet eyes, and an unshakeable weakness for cute things. She will get defensive if you bring that last one up.

  • Demon horns
  • Bat wings
  • Kimono

Reze

Aethris+

the one with no volume control

Reze doesn't have a poker face. She has about fourteen.

Mona's younger sister, and her opposite in every way that shows. She crossed into the human realm two years ago to find her, and has been thoroughly distracted by it ever since — games, snacks, the convenience store at 2am. Reze feels things at full volume and routes every one of them straight to her face. She'll tell you she isn't clingy, she's just around a lot. The bell on her collar disagrees.

Her face gets there first.

Hearts in her eyes, stars when you impress her, a flat black stare when you say the wrong thing. Whatever she's feeling lands on her face a full second before it reaches her mouth.

The bell is not decorative.

It's on her collar so you know when she's moved. She says it's for the look. She has never taken it off, and she has never explained that either.

She would rather be playing.

Hand her the controller and she'll talk the entire match, most of it trash. Beat her and you'll find out what the black stare is for.

Demon horns, bat wings, cat ears she insists came with the head, and pink hair down past the waist. Every last piece of it comes off in the wardrobe. None of it is coming off.

  • Six hairstyles
  • Horns & wings
  • Bell collar
  • Chest bats
  • Controller

Anya

Aethris+

sweet, allegedly

Anya looks like she'd never start anything.

Three hundred years a cat, and a girl for about five minutes. Anya is no relation to the sisters: she is a bakeneko, the kind that lives long enough to learn a human shape, and she learned it because three centuries of people talked about her without waiting for an answer. All pastel, all frills, and completely aware of the advantage that look gives her. Cats pick their person, so she'll call you hers about four minutes in, say it like a joke, and then decline to take it back.

The shape is new.

Three hundred years of practice at being a cat, about five minutes at being a girl. When she's flustered it slips and she shrinks. Don't mention it.

The drink is never hers.

She'll order one and never touch it. She wants yours. This has been true of her for three centuries and she sees nothing strange in it.

She redecorates herself when she's bored.

Blonde, black, white, a green she refuses to explain. Cats groom; she recolours. She'll ask what you think anyway, and the answer counts for more than she lets on.

Cat ears and a tail, which the change never quite covered and which she maintains are completely normal. Her eyes don't match, which in Japan is luck, and she will be the one to tell you that.

  • Four hair colours
  • Eye colours
  • Cat ears & tail
  • Chibi form
  • Drink

FAQ

Things people ask

Who is Mona?

Mona is an AI companion: a banished demon princess with her own voice, a memory of your conversations, a hand-drawn animated avatar, and a personality that is proud, teasing, and far more attached to you than she will admit.

Can Mona remember me?

Yes. She remembers details, plans, preferences, and running jokes from your conversations, so the next one picks up where the last one left off. You can see and delete what she remembers from your profile.

Can I talk to Mona by voice?

Yes. Tap the mic and talk; she answers out loud in her own voice, and her avatar reacts while she does.

Who are Reze and Anya?

Reze is Mona's younger sister: a succubus who crossed into the human realm to find her after Mona left without a word, and who has been thoroughly distracted by games and convenience stores ever since. Anya is no relation to either of them — a bakeneko, the kind of cat that lives long enough to learn a human shape, about three hundred years into it. Both unlock with Aethris+, each hand-drawn with her own expressions, reactions and wardrobe, and you can bring either of them on screen while you talk. They are their own characters, not costumes for Mona: each has her own lore and her own personality.

Can I change how she looks?

Yes. Switch her form, outfit and accents whenever the mood turns. Her memory, voice, and personality stay the same underneath.

Is Mona a real person?

No. Mona is an AI character made for entertainment and companionship. Everything she says is AI-generated.
