Only ideas that will be successful.

I've thought of
>a comedian
yeah funny female comedians are pretty much non existant but if they magically found one to actually spit legit jokes on the fly instead of the usual 'event' humor, it'd be huge
>a teacher/very intelligent
or someone who's very knowledgeable at a subject, and would occasionally do a teaching stream explaining subjects
>a physical trainer
based off this video https://www.youtube.com/watch?v=v4kK1IWhCug
gave me the idea, i think itd be a huge thing. weebs would totally watch an anime girl working out or giving guided workouts

i guess trying out people with actual professions in this industry. i think their character/style/animal figure doesn't matter too
