Ironmouse is a VTuber whose 2025 charity fundraiser for the Immune Deficiency Foundation ranked sixth on Tiltify's Top 30 Fundraisers list, and who is joining Fortnite Battle Royale as a collectable Sprite in Chapter 7 Season 3.
Ironmouse's 2025 charity campaign for the Immune Deficiency Foundation raised $1,376,362.80, placing it sixth on Tiltify's Top 30 Fundraisers list for 2025. The list, released in May 2026, showed VTuber-led campaigns accounting for about $1.956 million of the over $70 million total raised for nonprofits globally. Tiltify CEO Michael Wasserman credited VTubers like Ironmouse with making fundraising a visible part of their content, and noted that the platform's tools are designed for digital interactions, making it a natural fit for VTubers.
In August 2026, Epic Games announced that Ironmouse is joining Fortnite Battle Royale as a collectable Sprite in Chapter 7 Season 3. The Sprite grants players a special ability when equipped and launched with boosted drop rates on Tuesday night. The announcement came alongside two new Bleach collaboration cosmetics for Kisuke Urahara and Yoruichi Shihōin, launching Friday.
The two stories show Ironmouse's reach extending from charity fundraising into mainstream gaming crossovers. The Tiltify list placed her among the top fundraisers on the platform, and the Fortnite Sprite marks her entry into one of the largest battle royale games. No further details about the Sprite's ability or the Bleach cosmetics were provided in the stories.

Fundraising platform Tiltify released its Top 30 Fundraisers list for 2025, with VTuber-led campaigns accounting for about $1.956 million of the over $70 million total raised for nonprofits globally. Three VTuber campaigns made the list: Ironmouse's fundraiser for the Immune Deficiency Foundation ranked sixth with $1,376,362.80; Nimi Nightmare's Baby Bean's Charity Bash for St. Jude Children's Research Hospital ranked 17th with $361,042.03; and Mori Calliope and Koseki Bijou's "That's Wild?!" 24-hour charity stream for Wildlife Warriors Worldwide USA ranked 20th with $219,291.66. Tiltify CEO Michael Wasserman told VTuber NewsDrop that VTuber-led campaigns have grown year-over-year in both number and funds raised, and that the UK and Australia are strong regions outside North America for contributions. Wasserman attributed the growth to VTubers like Ironmouse making fundraising a visible part of their content, and noted that Tiltify's tools, including its API and incentives, are designed for digital interactions, making the platform a natural fit for VTubers.
