To every death, there is a reason. Behind these deaths, there are "Architects" who plan and design them. Follow Gunho, a Death Architect, and his group as they design masterpieces...

When the world is threatened by a parasitic alien invasion, our only hope lies with a group of super powered teenagers. But how can they save the world when they can hardly save themselves? Teamwork, optimism, and good intentions are seemingly no longer enough as each enemy is stronger than the last. They’re going to save the world, or simply die trying.
