Theme Song: Prodigy- The Prodigy - Girls
The Blackflow is an alternate world to ours. But BlackFlow is the world of currency controlled by a powerful man. There are those of us who can transfer ourselves into this Blackflow with a special Black Card. Given at any credit store when applied for. This Black Card allows us to transfer into the Blackflow.
Now this it the interesting part. To gain extra currency and more money on your Blackflow, you fight people in battles with your "Demon Contract". With is a Blackflow bodyguard of some sort, which you control. Each battle is based on currency. So the more currency you have by the end of the game makes you the winner of the battle. The losers go bankrupt. And their Black Card is destroyed. But what happens is something completely different. Not only do you loose your black card you also loose something in the real world of equal importance. Say you're married, well then you're wife may leave or simply not exist.
The RP would be about some agents trying to take down the Blackflow. Special money called called Black Currency is being transferred into the real world. Black Currency is special in its magical property to take on any value of money. These agents have to fight their way to "Lucifer" to bring down Blackflow. Its win or loose. The more you loose in Blackflow the more you loose in the real world. To the point where you may never exist.
