I kind of want a black butler AU where o!ciel also becomes a demon, breaking the contract in the process, but they still end up in the same roles and relationship because that's just become their (codependent) relationship and neither of them can or wants to change it. and even among demons, Sebastian's got the power to make sure no-one can mess with them or look down on them even if he's still playing butler.
Ooh I love this idea ! Maybe Sebastian refuses to go back to the demonic dimension because he doesn't want to be separated by Ciel if a summoning occurs, or if other demons don't approve of what happened, so they run away and hide among humans, traversing ages and traveling countries around the globe.
I love the idea of Sebastian teaching Ciel how to control his newfound demon powers.
Imagine Ciel getting angry, or his PTSD triggered, and he starts changing, black goo oozing from him, his teeth sharpening, his mouth widening, while the room around them become dark and everything starts shaking and Ciel doesn't even realize what he's doing as he's overwhelmed by his feelings and powers. Sebastian takes him in his arms and uses his powers to contain Ciel's, forcing him to stop.
