There is a normal human population in Other-Tokyo so organized crime is a possibility. Or they operate in the real Tokyo?

The idea of cross-dimensional Yakuza is hilarious to me.

What I sorta had going on in my head is that the Saejima family is pretty much one big family, but the two sides don't really know of each other (since the majority are just mooks). Only the really high up people with the witch blood actually know that the two sides exist.

In the real world, they'd do standard criminal shit and are more or less just organized crime. In the other world, they're more tolerated by Black Babel and the general government apparatus because they do work against other crime syndicates that try to cause actual harm to society. IE, they might extort businesses and do unsavoury things, but they also work to assist Black Babel and push out the gangs that are greedy and hinder the anti-vampire stuff. Also the idea of having an underground organization work with the government was always neat to me.
