It's probably a long shot, and I know you prefer no AU, but synodiporia's setting allows you to choose whether you'd like to AU your character into the current world they're exploring or not. There's a more detailed explanation for how all that works, but I figure I'll keep things brief here!

We've currently got Josuke (ob...viously lmao) as well as a Joseph, so we'd definitely love to see either Rohan or Caesar there! If you have any questions or want me to explain anything further, feel free to ask!
