"Honestly? It depends on how far you think Medaka Box's hax can get through those ridiculous Wings or not."
Aside from whatever metahax you can argue for like that "All Fiction" ability (I know absolutely nothing about Medaka Box outside of powerscaling tbh), doesn't Kami Tenchi, Counter-Actor and Chousin still neg-diff the verse and pretty much any Shonen Jump verse to date, including arguably Bobobo and Dr Slump (stretched arguments for plot manipulation and metahax for those verses aside)?
