The drafts for the best character lists are still in progress, so here's another character that might be on the list.

In Shimoneta, the government banned all forms of lewd content, Ayame is the daughter of a disgraced politician who fought against the legislation, not able to conform to the rules, Ayame takes it upon herself to become the masked terrorist Blue Snow, speaking lewd thoughts and spreading lewd literature everywhere wearing nothing more than a bed sheet and a pair of panties on her head like an anime Lady Godiva, her dub actress way more effective at communicating her lewd language, English has more lewd words than the Japanese.
In all honesty her energy is no different to how vtubers operate, watch anyone from Kson and Mori Calliope to Silvervale and Zentreya, and don't get me started on Projekt Melody just to give you an idea.
My point is, a big part of vtubers appeal is talking about lewd subjects casually, the same thing Ayame of Shimoneta is trying to achieve against a society that rejects it.
