Ironmouse

Ironmouse, born in August 2017 in the United States, is a VTuber and Twitch streamer who began her career as a singer. Initially aiming for opera, she shifted due to health issues from common variable immunodeficiency (CVID). Inspired by Kizuna AI, Ironmouse started streaming in 2017, adopting a horned demon persona with pink and purple hair. Her first singles, "Mad Mouse" and "Gremlin Fantasy", were released in 2021. She joined VShojo, an English-language VTuber agency, from November 2020 to July 2025. Collaborations with CDawgVA and subathon events boosted her popularity, making her the most-subscribed female streamer on Twitch by March 7, 2022. Her music career includes albums like Mouse Birthday Concert (2023), Sayton Gang: Attack of the Magic Cloud (2024), and Club Ironmouse (2026), along with notable singles such as "King", "The Vampire" and "Cry for Me", which reached number 21 on the Dance & Electronic Songs chart in 2026. Ironmouse won Best VTuber at The Streamer Awards in March 2023.
