In the near future, demons with the ability to fuse with machinery and infest corpses have begun terrorizing mankind. Dubbed 'Amalgams', no one knows how they are created, or where their abilities originate from. As the random outbreaks continue, the general population begins to panic, demanding protection from these vicious beasts; enter XAT, a military unit created solely to counter the Amalgam threat. Despite being a highly skilled unit, however, they find themselves hard pressed to contain the threat, let alone subdue it. To compound matters further, a new type of Amalgam surfaces that proves even more devious than the rest - one made from the human, not machine. Yet all is not lost, two of these new Amalgams - the feisty Gerd and the mysterious Blue - actively oppose the others. With the odds stacked against them, will they be able to protect mankind while simultaneously being shunned by it?
