Inspired by Dimension 20's season Never Stop Blowing Up, I felt it'd be fun to try to take NSBU's big mashup of everything in a genre and apply it to battle manga. But especially Yu Yu Hakusho because I'd just finished reading that. It takes place in 2024 in an alternate history: in 2008, Barack Obama sold Ohio to the devil to clear the national debt and prevent the 2008 housing crisis. It actually succeeded. The rest of the world is better off than ever. Proof that the Devil is real, but also just like, a guy, that provably improved everyone's lives, stopped christofascism dead in its tracks. Brexit and Covid also didn't happen.
Anyway though inside of Ohio, demons are running the show. There is a hellmouth over the capital, Columbus, and demons and monsters are running like, police forces and gangs and big companies fucking everyone over. Humans do have some access to magic now though too--secret societies coming out of hiding and demonologists and occultists tapping into Hell Energy for their powers. The only bastion of resistance is the Ohio River Valley and the greater Cincinnati Metropolitan Area, where proximity to the border keeps stronger demons from living there full time. The PCs are martial artists, magical girls, wizards, and half-demons living in Cincinnati. Good guys, working at least in alliance with The Society of The Cincinnati, a group of exorcists and demon hunters trying to drive out the demons. This year is going to have the world's first tournament-based mayoral election--everyone's getting ready for it to sabotage one another and recruit team members and figure out new weapons and techniques.
