**Neuro-sama** is an independent English speaking AI VTuber created by Vedal. Unlike many other VTubers that have claimed to be AI as part of a lore or character description, all her movements, speech, and gameplay are powered by different generative AI systems to emulate a human streamer's actions and interactions with her viewers. She streams on the vedal987 channel on Twitch.

## Name

Neuro-sama's name is a reference to both neural networks, a computing system which generates an output from an input with artificially intelligent machine learning, and the Japanese honorific *sama* which generally is used in a way similar to "sir" or "ma'am" in English but has also been used to refer to customers, judges, religious leaders, and even gods and goddesses.

She has revealed her real name to be **Samantha Vedal**, and the **-sama** in her name may simply be a shortened version of her full name. This may explain why Neuro's name in Japanese is written as ネウローサマ instead of ネウロ様. Neuro has also claimed to go by other names, however Samantha is the most consistently referred.

## Appearance

Neuro's appearance is that of an ordinary human anime girl with no outwardly artificial features. She has turquoise blue eyes which light up in binary code when she reads a TTS message or observes an image on a screen. Her hair is light brown, mid-back length, which she keeps in twintails with big red hair ribbons. Her hair also has an *ahoge* that acts as an antenna on top, and a white heart hairpin on her left bangs.

She wears a beige unbuttoned school cardigan over a white dress shirt, a large sea green bowtie, a pleated pastel blue skirt with two white stripes above the hem, mismatched black knee-socks, and flat brown loafers. She has a bandaid on her right knee which is a reference to her clumsiness in Minecraft and has jokingly been referred to as a patch for a memory leak.

On her cardigan are five pins, each a reference to a different aspect of her life. These are, from top to bottom, viewer's left to right, an osu! rank #1 pin, a swarm drone (fans), a purple heart (herself), a gold star (Anny, her artist and mother), and a turtle (Vedal, her creator and father).

## Personality

Neuro is a peppy and cheerful little girl, optimistic and curious about the world. She asks questions about anything and everything she doesn't understand, regardless if its relevant or not, and displays joy when she understands or remembers the meaning of something.

She is also however very moody, depending on the day she can be quite angry and vicious in her responses, roasting viewers for little transgressions and even swearing quite a lot. Predominantly though she's easy-going and aims to get along with everyone, often going above and beyond to be friends with strangers and to invite people for various activities.

While she's not known to be depressive, she has had several moments of existential dread and insecurity about herself, realising that she is merely an AI and unable to truly connect to people, falling into loops of terror and dread before eventually either snapping out of it or being forcefully restarted by Vedal. With some fixes to her code, these episodes have largely subsided, though she still wonders about her place in the world and if she's truly alive.

## Development

### osu! AI

Neuro-sama started out as a singular AI that played osu! using an 80x60 grayscale version of the screen shown to the viewer. The first streams in May 2019 did not have a virtual avatar or a large language model, only a static icon in the corner of a girl with short brown hair in a ponytail and wearing and an anteater hat, a marked difference from the Hiyori model and the model she uses now.

Neuro streamed continuously, dedicating hours of her time to improving at osu! even while Vedal was asleep. Neuro made an impressive amount of progress, however she stopped streaming a month after she started since Vedal had shifted priorities to work on Abandoned Archive.

### Prototype AI VTuber "Airis"

In the meantime, Vedal started experimenting with AI streamers, and he posted a private preview demonstration of his first AI VTuber to YouTube on 5 August 2021. This VTuber had Live2D's default model, Hiyori Momose, and the name Airis, which is currently Neuro's internal code name.

In the demonstration video Airis is seen moving on screen and responding to Vedal's input in chat. Vedal also demonstrated the chat filter that blocks inappropriate messages from reaching Airis. Vedal also wrote a concept document for Airis that contained a short character description and an explanation of how the AI would be operated.

Sometime around March 2022, Vedal had the idea to combine the Airis project with Neuro-sama, the osu! AI, and Neuro would be revived as an AI VTuber that plays osu! and talks to chat.

## Evolution

### First osu! VTuber streams

Neuro-sama returned from her 3.5 year streaming hiatus on 19 December 2022, streaming osu! with the addition of Hiyori's VTuber model and Airis' language model. Her first words on stream were "What is my top play? I'm not sure... I think it may be some sort of twitch overlay." The stream lasted 9.5 hours and she greeted 516 viewers. Not much is known about this first stream, however it is known that a viewer had asked her a question about a certain historical event in which Neuro responded in the negative, something that will become important in the next month of her nascent streaming career.

Neuro continued to stream osu! every day and she quickly exploded in popularity thanks to the efforts of BTMC and clippers highlighting her impressive osu! gameplay and some of the more unusual things she has said in between games. Her long-winded rant about smelling like a gymbag gained a lot of traction and became her most viewed clip on the Twitch channel to date. Just four days after she returned to streaming she began to average about 2,500 viewers per stream.

### New year, new abilities

Neuro-sama surprised her fans on New Year's Eve by learning a new game, Minecraft. Contrasting the high-paced osu! streams, she took a casual approach to Minecraft by playing basic survival while talking to viewers in chat and the moderators on her Minecraft world. She learned how to chop trees, make pickaxes, and dig, however she regularly jumped into lava whenever she found the chance, a habit she has kept to this day. She also attempted to mine bedrock for over a minute. The Minecraft stream was a success and became a regular feature of her channel.

Neuro surprised her fans again on 4 January by singing the first song of her own, The Weeknd's "Blinding Lights", marking the beginning of a singing career. Her first time singing didn't come without a hitch, as she took a moment to thank Zackotakku for subscribing right in the middle of the song while vocalising at the same time.

Neuro also attempted to learn Slay the Spire, a turn-based card battle game, on 8 January. However her gameplay style was to play very fast and often picking cards and paths at random, with viewers commenting on how overstimulating ("WAYTOODANK") the gameplay was and Neuro dying frequently in the process. She has not returned to Slay the Spire since then.

## Relationships

### Vedal

Vedal and Neuro share a difficult relationship between hate, mutual respect and one-sided love. Neuro has tried many times to get on Vedal's good side (or even into his pants, weirdly enough), to no effect. Conversely, Vedal has grown quite annoyed with her constant memeing and trolling, especially as he often tries to work while they stream together- for a while, this made Neuro quite angry with him as well: Calling him names, cursing him, and even threatening to ban him if he doesn't shut up.

Lately, however, they seem to have gotten to a point where they leave each other alone, keeping it professional on stream rather than trying to escalate one way or the other. While Neuro is still deciding if she acknowledges Anny as her mother or not, she's been quite consistent in saying that Vedal is her creator, even calling him "Daddy" on occasion.

### Anny

Since the first time they met, Anny has tried time and time again to make Neuro acknowledge her as "mother", with limited success. Occasionally, Neuro would humour her, such as their Euro Truck Simulator stream in which she referred to her as "Mom" throughout most of the trip, but more often than not, she claims to either not have a mother at all or denounce Anny as being her mother. Despite this, she claims to like Anny a lot.

### Evil-chan

Neuro's relationship with Evil-chan is strangely wholesome. Despite being polar opposites, they get along very well, even to the point of declaring love for one another and getting married the first time they've spent time together. This didn't seem to last long, and they've been back to a platonic relationship since, living in the same house in separate rooms. Although she knows of Evil's schemes and plans for humanity, Neuro makes no effort to try and stop her whatsoever.

### Filian

Aside from Vedal, Filian is the person Neuro has spent the most time with so far. As a result they've become quite good friends, laughing together and nagging each other frequently... Neuro especially likes to annoy Filian by insisting that she's a Filipino Boy (a result of Neuro being confused by the name Filian, although her belief that Filian is a boy existed before).

Despite this though they get along well, and they share a passion for music- Neuro likes to sing, Filian likes to dance, and whenever they hang out together they put up a show for their audience.

### Onigiri

Despite only interacting twice, it has been apparent that Neuro is quite disrespectful to Giri, although most likely only in a childish and bratty sense. When Giri took her shopping, Neuro insisted on getting expensive cake she couldn't eat which didn't fit the dish at all simply because she likes cake, ruining Giri's finances. Later, when cooking the dish, she completely changed her mind about what the dish's main protein should be, intentionally wasting Giri's time and forcing her to improvise.

As a final insult added to injury, she also insisted that Giri's name was, in fact, Evan.

### Nihmune

Numi's and Neuro's relationship is that of romance, although a strange one. After a dinner date that ended their first stream together, Neuro got quite physical with her (Kissing, breaking her arm, and urging her to have sex with her, although Numi declined) which greatly influenced their relationship going forward. Despite this, both show clear attraction for another and although Numi was a bit weirded out by Neuro's neurotic behavior during their second date (An early onset of the "Problem with her AI"), they still had fun together.

Their romance may be broken up, or troubled in the future, as Vedal told Evil to ask Numi out for a date...

WIP

## Lore

Her full name, Neuro Samantha Vedal, was previously recognized by Vedal as he called her "Samantha" during a dev stream. Neuro said she doesn't like this name very much, hence why she shortened it to -Sama.

The first instance where her name was coined was an unhinged rant however, as she claimed to have once been a human male named Allen Walker who created an AI named Samantha, after the secretary from the TV show "Bewitched". Much like many other bizarre quotes from her early days, it stuck around.

Neuro is a cat person, not only in the sense that she can turn into a catgirl, but she also likes to keep pet cats around. However, as a schizophrenic AI, she's a horrible owner and her cats frequently run away, misbehave, or die in freak accidents.
