Our society is infected with a disease, a gangrenous cancer in the form of those who commit the most monstrous of evils, yet whose power and influence place them beyond the reach of the law. When corrupt politicians fail to act and the police seem helpless, there is a third, secret option that stands ready to excise the malignancy in a tactical surgical strike: Black Label, a dedicated team of doctors, nurses, and students who moonlight as an elite team of assassins. With the world's deadliest nurse, a master swordswoman MD, an idol with an affinity for explosives, and a pair of seemingly indestructible high school students, their mission is as simple as it is deadly: identify the drug runners, terrorists, and criminal masterminds who can't be destroyed any other way, and then eliminate them by whatever means necessary in TRIAGE X!
