this logic somehow follows up with one piece. Did Brook have a similar problem at any point?

Sanemi was also doing it for years

he sees potential in humans, so long as they become demons.

Nothing probably, she's too passive to make a move, so she'll just end up heartbroken

so she knows flying thunder god. She should scale around the level of Sanin, then while being a bit stronger.

that might be the case

accurate, unless she still has weakness to sound, she shouldn't worry about much. And everyone dodges fire anyway

That's accurate

Big mistake

Muichiro should be slightly weaker 6 Giyu but will surpass him in a year or two
