>>70137246I'm assuming this is all hypothetical; since I haven't seen anything else about this. Realistically, her sister would have to be a massive retard to not talk with Cover first before attempting this. Negotiations should happen behind closed doors before a channel is even hinted at, let alone made. But assuming she IS a retard, Cover has a few options.
>shut her downShe's infringing on their IP. It's the simplest option, but heavy-handed and likely to be bad for PR.
>have her change the names to something legally distinctThis is a perfectly valid option if the issue is more "we don't want someone representing our IP when they don't answer to us". It's a nice middle ground that nobody would complain about.
>let her continue, but ask for a cutIf this happened you would never hear about it because it would be done behind closed doors. It's a reasonable option since she's profiting from Hololive IP. She effectively becomes a subcontractor.
>let her continue without contestYou would never know the difference between this and the previous option, so there is no point discussing it.
>What if she starts flesh tubing and showing nerissa irl?Cover doesn't care about this at all. Noel fleshtubes and nobody minds. Their only concern is with their own IP.
