Okay, good stuff. Gives me plot and stuff to throw out.
Here's my new take on the setting.
As you know Black Tokyo is along side of the 'real' Tokyo, one of separate, and not-so-separate realms where everything is exaggerated and dark. The key point is that the real world has links to it. Portals where people slip into and fall. And true to nature it doesn't care who it takes in. The innocent, the vile, the pure or the debase. All are welcome in there.
Those traveling to the other side, however, is much rarer.
Now, the setup is that at the current school, of which I'm looking for a name, there have been students disappearing late at night, during after school activities, with some of them having been returned violated, but alive. However, the returned don't seem to think that they actually left the school...
The police are baffled, students are scared, but none want to leave, because until recently, it's where all the best come from. The record of employment or attending good universities beats any other school in the prefecture.
A few changes, a lot of the Forum rule breaking monsters are gone. Okay, ALL of them are gone. The Ironclub Oni do NOT have a female species (Makes them less Hentai to do so in my mind.) Kitsune can hide their tails in full human form, but the mirror flaw stays. And as everyone pointed out death won't as pervasive as it seems to be in the book.
Other than that, I think we're good to go!
