The day the Bijuu screamed, was a day that changed the world. A wail was heard across the nations, nine screams echoed across the world, and a few days later a plague had spread across all of the elemental nations, it spread like wildfire within a month every living being on the planet had it, every man women child animal and plant had it. Every quarantine failed, every vaccine had been toppled, and nearly all hope had been lost. The few with any hope of surviving this were the young, and even then there was no guarantee that they would live, already thousands had died, it struck fast and left many dead in its wake, the ninja with the most chakra, seemed to be hit first, within eleven weeks, every one over the age of twenty had been killed by the plague, and finally the tide of bodies had started to thin, finally the death had start to slow and hope had been returned in just under three months the world had been brought to its knees.
