There's a lot of misinformation here.
V4Mirai was not bought by Brave Group, it was always a Brave Group project, it's right there in their twitter description:
https://x.com/V4Mirai>Brave group launches it's first English-based VTuber project!Mariya's alt "Prisma" was created during her time in V4Mirai to play Apex with men and trannies so she could separate it from her "Mariya" identity which was heavily lewd ASMR and GFE. Prisma used a throwaway mass produced model.
A single 2D model from an esteemed artist like Itiso can cost the corpo $10k easily. Actual quality 3D models and not shitty VRoids can cost $5-$15k, probably more for the corpo.
Brave ad-boosted her account to 85k subscribers, plus paid for her mic, 3D tech, games, software, cover songs, original songs, artwork, concerts, merch production, etc. To "buy back" the IP is not just the model, it's the entire investment into her accounts.
And yes, Mari masturbated during ASMR and it was fucking hot :)
