Kudou is so well-written, oh my god. She plays off all the preconceptions people have, that surely subs cannot abuse people, and surely dommes can't be abused, while also being a foil/parallel to like... every other main cast member? I'm baffled how the author pulled this off. I was so skeptical of her at first, but now I see, I was simply unfamiliar with Kuwabara-sensei's game.
