ironmouse (born: January 11) is a Puerto Rican VTuber. Initially an independent streamer, she was hired and sponsored by VShojo later in 24 November 2020. She streams anime, plays video games, and is famous for her singing with her high-pitched voice, with her most popular video being her cover of Kulikitaka-ti, which became a meme and was spread cross several platforms.


Ironmouse's channel was made in 2017, but she didn't make her VTuber debut until February 2020[1]. The main purpose of her channel was to upload clips from her Twitch streams[2], often of her streaming games like Aliens: Isolation. In November of the same year of her debut she announced that she was affiliating with the company VShojo, which was accompanied by a music video and MMD[3]. This inspired her to make more music videos[4]. She is also a singer and covers rap songs, having lent her voice to many anime fansongs[5][6][7][8].

She also began making story time videos around this time and has gone into detail about her Puerto Rican and Hispanic roots before[9]. She is multilingual, speaking English, Japanese, Korean and Spanish, and made a video for her Spanish fans[10].

Games she has streamed on her channel include It Takes Two, Super Bunny Man, Resident Evil Village, Fall Guys, Among Us, Devour, Dark Souls and Grand Theft Auto.

Her name comes from her nickname at school; she was always small (she is 4'10) and was therefore dubbed "mouse". It also comes from her favorite Sailor Moon character Sailor Ironmouse.


She is a host of the Lewdcast alongside Melody and Silvervale. She is a regular on the Rant Café Anime Podcast.

When she was new to the YouTube scene, she appeared in one of Projekt Melody's stream, where she was given the moniker "Mad Loli". Her channel popularity got a boost thanks to a collaboration with Nux Taku and Lost Pause, and she often collaborates with them.[11]. She has also appeared in the latter's Weeb Wars game show.

She has also collaborated with several big name YouTubers such as Videogamedunkey and CDawgVA, and has a close friendship with the latter, as they often collaborate and he even cosplayed her[12]. There is also a running joke in their fandoms that the two are romantically involved, however they both have denied this, and Connor actually has a girlfriend in real life, whereas Mouse's condition renders her unable to have sex and having a baby would potentially kill her[13]. Ironmouse was also one of the VTubers featured in REACT's episode of "Teens React to VTubers".[14]

Her voice acting roles include Truck-chan from That Time I Got Isekai'd To Another World With My Truck!!!.

Amano and Ironmouse once held a chatting stream that was over 2 hours long[15]. She has also played Phasmo[phobia with Bonnivier Pranaja.

She is a Twitch partner, and often participates in Twitch game shows/tournaments:

  • She has several nicknames such as Mousey, Satanas, Mad Loli and Yandere Mouse, but a lot of fans call her "Tungsten Cat" after CDawgVA joked about her debuting under that name, because she always has to explain that she is not a mouse, she is a demon.
