Popular VTuber and Twitch creator Ironmouse rocked her fans by announcing this week that she'd left VShojo, a talent group she co-founded just five years ago. On her way out, Ironmouse levied some serious, if not substantiated, allegations.

It's a major story for one of the world's most popular VTubers — someone who uses a virtual avatar to stream.

"With the information that I currently have, I believe that I am owed a significant amount of funds, which I have not been paid," Ironmouse said in a YouTube video announcing the split the VShojo. "And most importantly — the thing that hurts me the most — is that the Immune Deficiency Foundation, which is the most important charity to me and also the reason I am here today, is owed over $500,000 from VShojo."

The details thus far are scarce, which seems to be a legal strategy from Ironmouse.

"I really want to tell you everything but unfortunately, right now, I have been instructed by my attorney to wait for more of the legal procedure to unfold," she said in the video.

Ironmouse did allege in the video that VShojo did not donate money from a subathon that was earmarked for the Immune Deficiency Foundation. Other creators have come to Ironmouse's defense, as Sports Illustrated's Esports vertical noted.

It's not yet clear where the story goes from here, but the fallout will certainly continue to grow with the departure of someone as popular as Ironmouse.
