Why does Hololive continuously introduce character lore that's at odds with their nature as an idol agency? Let's look at a few Hololive members, shall we?
>Mumei
Supposed to be a guardian of civilization. Can't actually talk about civilization or human history because of political yabs.
>Aloe
A succubus. While she never got her chance to shine, it's fair to assume she wouldn't have been allowed to talk about actually acting as a succubus - having sex - on stream.
>Subaru
A tomboyish bokukko. Each one of her outfits gets progressively more feminine than the last.
>Mori
A rapping reaper. She can't say nigger or actually act thug at all beyond her tsundere shtick.
Explain this.
