Slightly AU. Before he was Allen Walker, he was simply Red. A distrustful, realistic and cynical opportunist. A survivor. Holding the power to either make or break the world, will he take his rightful place in the war or simply stay out of it? COMPLETED. Editing underway.

Allen is sent off on an asignment, however the place he's sent to isn't normal. It's the Circus of Night, a place that caters to everyones desires, whether they know what they are or not... This is not Pure Yullen, stop bitching about the lack of it, this is a STORY, with a PLOT, that contains other pairings WITH Allen in them.
