After the Fourth Great Shinobi World War ended, the world was experiencing a time of peace. The villages for once were able to live in relative harmony with one another as they rebuilt, and for once, all seemed to be well. The kage were able to live peaceful lives and soon began retiring, passing on the baton to the next generations. That is until an unknown virus infects the northern coast. The first to fall is the once powerful Raikage, Ay. While many thought this virus was a simple mutation of what may have well been the flu, no one would ever think of the destruction it would cause. Especially when it infected a certain Uzumaki Naruto.
With his death came the malice; with the malice came the destruction; with the destruction came the shinobi' revolt; and with the revolt came the sacrifices. The Bijuu became filled with malice that they sought to destroy the world. Shinobi sought a way to fight them and once again capture each of the Bijuu. Time passed, and a plan was devised. The Jinchuuriki would be sacrificed for the greater good of the world, and with the deaths of nine individuals, an uneasy peace began.
As time continued, the villages began to truly restructure. In a peace that would last 80 years after the downfall of the Bijuu, the world would see the creation of a great many things. Technology was beginning to take root and before long the blossoms that grew from the tree of the advanced mind would bear fruit. A many great things came to be. A railroad between the vast many nations. Mechanical limbs to replace lost ones. Radios that could reach between villages. Everything seemed to be becoming less reliant on the shinobi. Only the need for them never truly vanished. As with the growth of time, also continued the growth of malice.
