Compsaurus (コンプサウルス) is a female Japanese Virtual YouTuber who debuted in 2022 as an independent. In August 2025, she joined Uniraid!, an isekai-themed VTuber agency, re-debuting alongside Kagariya Renma, Tokiha Shiu, Naruko Raichi, Sei Lunathia, and fellow indie Granite as a member of LIEMEL, Uniraid!'s Generation 3.
She mainly streams her favorite game, Fate/Grand Order, but will also occasionally stream other games.
Introduction video[]
Profile[]
A gyaru dinosaur who entered a strange door and was reincarnated into another world.
Currently, she works at a cafe called "Opalize", lit up with a bright neon sign, together with its manager named Ammonite. Because of her overflowingly curious personality, she is also a chatterbox who can just keep talking, nonstop.[2]
Personality[]
Compsaurus has a very curious personality. She can talk endlessly with or without people around her, with a surprisingly gentle and soothing voice, even for a dinosaur gyaru.
She also declares herself to be the president of an anti-"reverse bunny girl outfit" association, proclaiming the supremacy of standard bunny girl outfits.[3] After bunny girls, her second favorite are maids, if she had to choose. She also likes shrine maidens whose outfits have sideboob windows. Lastly, she's a complete masochist.
Appearance[]
Compsaurus has short purplish-gray hair with black highlights. She has heterochromatic eyes with a magenta iris on her right eye and a violet iris on her left eye. She has pointy ears with two silver earrings on her left ear. She also has a distinctive beauty mark below the left side of her mouth, as well as two pairs of small fangs, both upper and lower when she opens her mouth. As a dinosaur girl, she has purple crystalline horns on her head, and a large purplish-gray tail with purple crystalline protrusions, similar to a stegosaurus tail.
For her original design, she had wavy pink hair, and eyes with blue irises. Her ears had multiple piercings and she had a black hairpin with three hearts adorning the right side of her bangs.

Miscellaneous[]

- She has chatbanned many (and continues to actively ban) viewers who break her rules in an effort to maintain a safe and friendly live chat section. Bans happen frequently.
- She's mainly a Fate/Grand Order streamer and has been streaming it for a long time. She talks about other things as well when streaming F/GO, but aside from this she also plays many other games.
- The first Pokemon game she ever played is Pokémon Black and White, while the first handheld console she owned is the Nintendo DS, with the 3DS being the first one she bought for herself.
- Her grandfather owned a Gameboy Pocket/Gameboy Color, so she claims that she's tried those as well.
- Her father owned a Gameboy Advance SP.
- She still plays the original Dragon Warrior Monsters and doesn't acknowledge the remake. She claims to have been playing it since she was born, and has played it again this year as of October 2025.
- She's never tried the original PlayStation and doesn't know the PS2 or PS3, but she's at least seen a PS4.
- She loves watching people play Detroit: Become Human and she had a great time playing it for the first time.
- On 11 June 2022, she tried VALORANT for the first time. Not long after on 23 June 2022, she quit the game.
- She is against having any gachikoi in her fanbase, because they're nothing but trouble from her perspective.[17]
- As of her re-debut into Uniraid!, 50% of her channel viewers were made up of middle-aged men, followed by 20% perverted old men, 20% neighbors, 5% chatbanned viewers and the final 5% are ladies, who she has declared her love for.[18]
- In MADTOWN GTA, she met the Japanese radio personality Mafia Kajita who's known for regularly appearing in Fate/Grand Order (her #1 favorite game) livestreams (he even voiced a character in it), who recognized her as a longtime F/GO streamer. She left the encounter feeling absolutely starstruck and hyped up.[19]
- During that event, she also confessed to buying hundreds of adult manga on the Japanese digital media store DLsite, particularly from DLsite garumani (Girls Maniax, basically the Women's R-18 section on DLsite). She says she reads all sorts of genres, so long as the art fits her tastes and the story is interesting enough. Most of the eromanga she bought are female-oriented titles, because typical storylines in male-oriented eromanga are often too simplistic for her.[20]
- Compsaurus shares her current character designer shuri with Mochituke Nullpo from FIRST STAGE PRODUCTION, as well as the independent VTuber Kuramochi Kyoko.
