Ironmouse has once again proven the power of the VTuber community by raising an astonishing $1.1 million for the Immune Deficiency Foundation (IDF) during a recent 48-hour charity stream. The independent content creator not only reached this impressive milestone but also broke her personal record for the highest Twitch Hype Train level achieved during a single broadcast.
The fundraiser means a lot to Ironmouse, who lives with Common Variable Immunodeficiency (CVID), a condition that severely compromises her immune system. Before launching her virtual career, Ironmouse was training to become an opera singer when her CVID diagnosis drastically changed her life, leaving her largely bedridden.
“She regularly fundraises for the organization since she’s already rich,” noted one supporter, highlighting how Ironmouse has consistently used her platform to give back to the foundation that once supported her and her family during tough times.
The Immune Deficiency Foundation is a nonprofit organization focused on improving diagnosis, treatment, and quality of life for people affected by primary immunodeficiency disorders through advocacy, education, and research. Some initial confusion popped up online because the “IDF” acronym is also used for the Israeli Defense Forces, but viewers quickly cleared up which charity Ironmouse was supporting.
Ironmouse’s achievement puts her up there with the biggest charity fundraisers on Twitch. The platform’s features like Hype Trains—which reward streamers and viewers for rapid-fire subscriptions and donations—helped boost the event’s incredible momentum. Viewers got behind the cause, setting off a wave of donations that pushed Ironmouse to smash her previous record.
Since starting her VTubing career, Ironmouse has become one of the top virtual creators out there. After previously being tied to VShojo talent agency, she now streams on her own while keeping her signature pink-haired demon princess look and showing off her powerful singing voice.
This charity milestone keeps the momentum going for creators who use their communities to do good. For Ironmouse, the $1.1 million she raised isn’t just a huge number—it’s a win that means a lot to her, supporting an organization that helps people with struggles just like hers.
