Where did I come from?

Ironmouse's introduction.


Ironmouse is very chaotic by nature, she asks the strangest questions or talks about the strangest topics out of the blue and often leaves collaboration partners speechless with her uncensored words. Her suggestive language sometimes causes her to delete her own VODs for fear of possible TOS penalties. She cares a lot about her friends and gets sad when she hears someone being mean to them, even more so than when they are being mean to herself. While she is very confident when she is streaming on her own, she is very shy when it comes to connecting with other people and usually gets nervous when anyone other than her closest long-term friends are around.

Ironmouse is generally very friendly, but when she plays a game where she has to kill other players, she likes to laugh in a crazy with the slogan "I love you so much that you have to die". In these situations, people often start calling her "Yandere Mouse". She is also known to roast people who are rather annoying in chat or accuse her of being a man or using a voice changer. She is known to be easily scared and likes to stall before and while playing horror games, but at the same time she loves the feeling of being scared, which is why she likes playing scary games.



Ironmouse debuted in 2017 on a smaller streaming platform. In late 2019, she switched to Twitch as her main streaming platform.


Ironmouse became a Twitch partner on 5 May 2020[3] and YouTube partner on 1 Jul 2020.[4]

On 24 November, she announced her membership in new VTuber agency VShojo as part of its first generation, alongside Projekt Melody, Silvervale, Zentreya, Nyatasha Nyanners, Froot and Hime Hajime. Her introductory video was drawn by Froot, and featured a brief cameo by Hime Hajime, who appeared on the cover of a book which Ironmouse reads. She introduced an updated version of her model. Ironmouse promised that "Nothing will change. Jack shit will change. You know why? Because VShojo is talent-first. We're all fuckin' free to do what ever the fuck we want!"


On 15 January, she revealed longer hair as an update to her "Season 1" 2D model, which was adopted from her 2020 Christmas costume.

On 11 February, she revealed a new 2D model along with the "Seasons" concept, explaining that each model has its own backstory in a different universe and has its own designated season[5].

On 03 March, Ironmouse was featured on REACT, a popular YouTube channel, in an episode titled "Teens React To VTubers."

On 12 March, she unveiled a new 3D model on Twitch, made by TheArtGun, before it was to debut the next day.

On 13 March, she hosted a special 300k YouTube subscriber celebration stream on her YouTube channel, where she also officially debuted her new 3D model. Before unveiling the model, she used an unfinished version as a joke, which was mostly bald.

On 31 March, Anthony Padilla released his YouTube video "I spent a day with VTUBERS", in which he interviews Ironmouse along with Nyatasha Nyanners and Zentreya.

On 13 April, VShojo members Ironmouse, Froot, Silvervale, Veibae and Nyatasha Nyanners played with prominent japanese VTubers Kizuna Ai, Higuchi Kaede and Dennou Shojo Siro in a collab called #VAmongEarth.[6]


Rap Cyphers

  • Ironmouse is a demon queen from the depths of the underworld ("not underwear. Underworld") who came to the human world after becoming obsessed with human culture. However, her power weakened as she spent more time away from her home world.
  • Ironmouse began streaming after becoming obsessed with VTubers. She discovered that she has the ability to absorb human souls, the only energy capable of sustaining her, via the internet. She no longer consumes human souls, but subsists on piece of the soul energy of her viewers.
  • The two silver bells she wears in her hair constrain her power, allowing her to assume a weaker form. This is necessary to allow her to stay in her beloved human world for as long as possible.
  • She has the ability to shapeshift into any form, although she cannot use it without consuming too much of her power. She can appear anywhere in the world at any time, and "You'll never find me in space!"
  • She claims to have 5 hearts. 1 in her head, 1 in her chest, 1 in each foot, and 1 in her posterior, states this is normal demon anatomy.
  • Ironmouse has a twin sister named Aluminum Giraffe. She has orange hair.


  • Each universe has its own version of Ironmouse. To distinguish the stories of each version, they are separated by "seasons" and in each universe she has a different appearance (2D model).[5]
  • Lost Season: Universe 000 is where "Baby Mouse" lives. In this world, Ironmouse lost her memories and was trapped in another person's body. She was able to jump from body to body, but could never take an original form.
  • Season One: Universe 111 is where she came into the human world, but her unstable power kept causing problems with her original form. In this world she never went back to hell and Bubi (her demon attendand) remains back in hell. In this world she found Vshojo and lives out her life as a Vtuber.
  • Season two (current): Universe 222 is where she has lived in the human world for a long time, but periodically goes back to hell (Which resulted in the wifi being much more stable down there). In this world, Bubi has come from hell to our world to watch over Ironmouse, protect her and have fun with her. Through Bubi's help, she found Vshojo and became a Vtuber to supply herself with soul energy.

She hopes one day to be healthy enough to wrestle Nyanners.
  • Her streams are very diverse and range from chatting, singing, occasional voice acting, to playing games.
  • Due to her health condition, her streaming times are very restricted. Ironmouse has [Common Variable Immune Deficiency] (CVID), a disorder that impairs the immune system. People with CVID are highly susceptible to infection from foreign invaders such as bacteria and viruses and often develop recurrent infections. It is because of this that Mouse has no option but to remain indoors and bedridden.
  • Before Mouse became really ill, she attended a performance arts high school, where she studied musical theater. The years of training before she became bedridden have proven to be very useful when she sings.
  • Her first 3D model was hardly ever used because all the equipment required was very physically demanding for her. Her second 3D model is much easier to use, requiring much less equipment and also providing very detailed eye and mouth tracking.
  • Mouse speaks fluent English and Spanish. She also speaks some Japanese and is working on learning Korean. While she speaks and sings mostly in English and Japanese, she occasionally speaks Spanish or sings songs in Spanish, Japanese, or Korean.
  • Ironmouse is Hispanic, Puerto Rican.
  • Origin of her name: Ironmouse has always been small. When she was in school, she was called "Mouse" because of this. One of Mouse's favorite characters is Sailor Iron Mouse. When Ironmouse started breakdancing and became a B-Gril, she got the name IronMouse because of her favorite character and because of her size.
  • She hosts Lewdcast, a "Weekly Variety VTuber Podcast", along with Projekt Melody and Silvervale.
  • She refers to collabs as "play dates".
  • One of her popular songs is Mousey in the Bathroom, a parody of "Michael in the Bathroom" from the musical Be More Chill.
  • In 2017's "Lost Season," she began trying out various pre-made models, mainly using a model of the character "Tohoku Kiritan" to see if she liked streaming, until she finally decided to commission her first 2D model of her own, which she unveiled in December 2019.
  • On 26 February 2021, she unveiled a new Twitch channel intro titled "Mad Mouse", which is based on the music track "Marble Zone" from the Sonic games.
