>etablished, well oiled company
Haachama was Hololive's sixth talent to debut.
Not sixth generation. Sixth talent.
At a time when Hololive ran straight into the Hitomi Chris termination and a few months before Mel's manager started harrassing her.
I don't know what your definition of "established, well oiled company" is, but I don't think Hololive, circa June 2018 is matching it.
I'd not allow underaged talents if I were to run a vtuber corp due to how sexualised the industry is, not wanting to deal with adolescent starlets, not wanting to deal with adolescent starlets' parents, and believing that streaming should be a hobby first, therefore have something you can fall back on if streaming doesn't work out, and that's just not going to happen if you start at sixteen or whatever, but describing 2018 Hololive as established and well oiled is... well, I'd have rated it a baitpost if it wasn't from you.
You're probably serious.
