Ironmouse

Ironmouse is a Puerto Rican VTuber, singer, and Twitch streamer who has been active since 2017. Originally training to be a coloratura soprano opera singer, her plans shifted after she was diagnosed with common variable immunodeficiency (CVID), a serious immune disorder that has kept her largely bedridden. To cope with isolation, she began streaming with a digital avatar inspired by Japanese VTuber Kizuna AI, choosing to create a character that is a playful demon queen persona—a bigger, superhero-like version of herself. Known for her distinct high-pitched voice, which is natural and linked to her health condition, Ironmouse quickly became a beloved figure in the VTuber community, joining the pioneering group VShojo in 2020 and gaining a massive following on Twitch, even briefly holding the record for most subscribers.

Beyond streaming, Ironmouse has developed a vibrant music career, releasing J-Pop and electronic-influenced tracks such as "Sayton Gang: Attack of the Magic Cloud" and "Super Shy," collaborating with producers like Shirobeats and Camellia. Despite health challenges, she streams daily and is celebrated for her lively personality, humor, and dedication to her community. Her story is one of resilience and creativity, blending her love for music and performance into a unique VTuber experience that continues to captivate fans worldwide.
