Disclaimer: All names contained in this post have been deliberately made public by the person themself.
Model makers, riggers, musicians, artists, and all others involved in the making of vtuber shows are all carefully credited, since it would obviously be reprehensible not to do so, but the actual performer that portrays the Idol goes entirely uncredited. The performers are all experienced entertainment industry professionals, Hololive does not and has never contracted unproven talent. Most of them have IMDB pages but universally their biggest and most prestigious work is not listed there, because Hololive forbids it.
When Rebecca Cardenas went independent as Dooby one of the very first things she did was make her identity public specifically to take credit for some previous work she's done. But even after going independent she is still seemingly contractually prohibited from taking credit for portraying Ame, something that might actually be illegal in my opinion. Rebecca should be able to list her time portraying Amelia Watson as part of her professional work experience.
I am not saying that all the talent should be forced to make their identities public, rather I think they should be credited by a name which they control. For example, the performer portraying Takanashi Kiara does not own that name and could not use that name when doing other work, but she does own the name Keekihime. So while some talent, like Karen Calanni playing Mori Calliope, would want to be credited by their real name, others, like Keekihime, might rather be credited by a stage name. The important part being that they control the name themselves and can use it as they wish.
Hololive refusing to credit the performers unfairly shackles them to the company and inhibits their professional careers, and that's messed up
Okay sure I'm not gonna say he's wrong because sure given that arresting the head of state of a powerful nation would carry immense consequences I can believe that most countries would just rather not do it, no matter the severity of the crimes, as he said that's just realpolitik.
But to freely admit that you would ignore your legal obligations when you didn't have to is just so fucking stupid!
My point of view on this is that the ICC is an arm of the rules based global order, which was constructed by and in the interest of "the west". Which means this statement delegitimizes the ICC therefore degrading western interests, so it real damn idiotic for the leader of Belgium to say this since it's essentially the capital of "the west"! Politicians may have a reputation for doublespeak but that's because there are a great many truths you simply can't say if you want to further your political interests.
