Ironmouse is a Puerto Rican-American VTuber and Twitch streamer who has become a trailblazing force in the world of online content creation. She began her virtual journey in 2017, quickly drawing attention with her infectious energy, operatic vocals, and her signature pink-haired demon queen persona. In 2020, she helped launch VShojo, one of the first major VTuber talent agencies in the West, helping to bring the VTuber phenomenon into mainstream Western culture.

What makes Ironmouse truly remarkable isn’t just her entertainment value, but her perseverance. She lives with common variable immunodeficiency (CVID), a chronic illness that severely affects her immune system and keeps her homebound. Despite this, she’s built one of the most loyal and supportive communities on Twitch. She’s been candid about her health challenges, often using her platform to raise awareness and support for those with similar conditions.

Her subathon streams in 2023 and 2024 made history, not only breaking Twitch subscription records but also raising substantial funds for the Immune Deficiency Foundation. In September 2024, she became the most-subscribed streamer on Twitch with over 312,000 active subscribers, a groundbreaking achievement.
