Before unveiling the model, she used an unfinished version as a joke, which was mostly bald. 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. On 09 March, Ironmouse was featured on REACT, a popular YouTube channel, in an episode titled "Teens React To VTubers". 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.
On 15 January, she revealed longer hair as an update to her " Season 1" 2D model, which was adopted from her 2020 Christmas costume.
We're all fuckin' free to do what ever the fuck we want!" You know why? Because VShojo is talent-first. Ironmouse promised that "Nothing will change. She introduced an updated version of her model. 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. On 24 November, she announced her membership in the new VTuber agency VShojo as one of its first members, along with Projekt Melody, Silvervale, Zentreya, Nyatasha Nyanners, Froot and Hime Hajime. On 01 July, she became a YouTube partner. On 15 May, Ironmouse became a Twitch partner. In late 2019, she switched to Twitch as her main streaming platform. Ironmouse debuted in 2017 on a smaller streaming platform. 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. She gets very emotional when she talks about how far she has come against all adversity. Even the name "precious family" that she chose for her community shows how much she loves what she does and how grateful she is for the love that the community gives her. She is very hardworking, as she puts in effort every day to stream and provide content for her viewers despite her circumstances. There were also rare instances when she acted in a "Yandere"-type fashion, laughing maniacally and saying things like "I love you so much that you have to die", these flashes of yandere appearing in games where she had to kill off her collaboration partners. Tsundere is a Japanese term for a character who is caring but has difficulty expressing positive feelings for someone and instead acts temperamental and hot-headed. She is generally very friendly to everyone except when she roasts people who are mean in chat or when she occasionally behaves in a "tsundere"-type fashion. Her abundant charisma is easily recognized by the way she makes people smile, feel comfortable, or get emotional. 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. If not completely gone, at least she no longer deletes VODs for fear of possible ToS bans. In her early streaming days, she used a lot of suggestive language, but as she developed more confidence, this behavior decreased. Over time, she learned to control herself better, but she doesn't always succeed, especially when she's around like-minded friends. Her chaotic nature was more pronounced in her early streaming years, as she tended to ask odd questions out of the blue or talk about the strangest topics, often leaving her conversation partners speechless because she had no filter. She was very nervous around others, but over the next two years she developed more and more confidence. In early 2020, she was very shy and only showed confidence when streaming alone or with close friends. Ironmouse's behavior is so lighthearted and funny that there isn't a stream where she doesn't make her chat or streaming partners laugh. All she wants to do is to have fun and see what the human world is all about and… make as many souls friends as she can. It has been said that once the bells are off, her true demon queen form will be revealed. If her bells ever get removed, pure chaos would ensue. She wears special magical bells on her body to contain and control her power in order to better blend into the human world. She has an obsession with the internet, music, lewd stuff, nerd shit, and all things cute. She is a friendly, fun loving demon who ran from her duties and escaped the confines of Hell/the underworld in order to make new friends, learn new things and live life to the fullest. A demon queen who goes by several names… but has also been rumored to be Satan herself.
