Names can be deceiving, something the warrior known as Hero quickly discovers when he storms the castle of the dread Demon King that mankind has fought for fifteen years. For one thing, the "king" turns out to be a queen! Even more shocking, though, is that she's waiting for him with an unexpected proposal.
She points out that it would be bad for both sides if the war was to end immediately, as without a common enemy, the individual factions of the winning side are certain to turn on each other in a new series of civil wars. However, she has a plan to end the war, bring democracy and advanced knowledge to humanity, and ensure lasting prosperity for both sides, no matter who "wins." But to accomplish this, she needs a collaborator on the human side, and she's chosen Hero as the one partner she can trust! Is it a deal with the devil, or mankind's only hope for lasting peace?
