Who is Ironmouse?
Ironmouse is a Puerto Rican VTuber, singer and livestream creator active since 2017. Games, conversation, singing and collaborations are central to her work. She announced her departure from VShojo in July 2025 and continued as an independent creator, rather than a current member of that agency.
Her high voice and quick conversational reactions are immediately recognizable, but music is also a sustained part of her creative identity. Her background in opera training helps explain why singing is more than an occasional break between games.
The demon-queen character
Her virtual persona uses a demon motif, including horns, wings and pink-and-purple hair. Its fictional setting describes a demon queen who leaves her duties to experience the human world and make friends, with magical bells restraining her powers.
That setting belongs to the character. It offers a playful framework for the contrast between mischievous jokes, a cute visual presentation and conversations with other creators; it is not a description of the performer's private identity.
Carry On and charitable work
Carry On is a useful starting point for her recorded music. The release credits Ironmouse, shirobeats and the Immune Deficiency Foundation. The foundation connects the song with its documentary Compromised: Life Without Immunity.
The project brings her music and public support for the primary-immunodeficiency community into the same context. The foundation's account of her advocacy also documents the June 2024 release and fan support for its work.
Her 2024 charity subathon is another landmark. At the time, it passed Twitch's subscription record, with reports during the event already exceeding 320,000 subscriptions. That is a historical achievement tied to a particular event, not a current subscriber count or a claim that the record remains unbroken. Extended broadcasts, guests and community participation help explain her place in English-language livestream culture.
Awards and the move to independence
Ironmouse won Content Creator of the Year at The Game Awards in 2023. That recognition placed her work in a broader gaming and creator context, beyond an award restricted to VTubers.
Her own Why I left VShojo, published on July 21, 2025, marks another change in her career. It is a first-person account of leaving the agency. Describing her as a former founding member preserves the historical relationship without presenting it as a current affiliation. The video is useful for that career transition; it is not presented as a representative music or entertainment work.
Precious Family and names used by fans
Precious Family is the name associated with her fan community. Public material uses #ironmouseparty for streaming and personal activity, #preciousfamily for fans and #ironmouseart for artwork. The stage name Ironmouse and the public handle ironmouseparty refer to the creator's public presence; this profile does not speculate about an offline identity.

Where to start
Carry On introduces the singer and her connection with charitable advocacy. A longer conversation or collaboration stream shows the quick, improvisational side of her performance. Her departure video explains the later change in affiliation. These entry points cover music, livestreaming and career history instead of treating them as interchangeable recent uploads.
