Ten years ago the Fourth Great Shinobi War was waged by former Uchiha Clan leader: Madara. The Five Great Shinobi Countries combated Madara and the six remaining Tailed Beast with all their might and they survived to the end. However like the past Great Ninja Wars, the economy was so devastated in each of the participating nations that the villages fell. The war had also taken its toll on the other shinobi nations who also helped fight causing them to be wiped off the face of the earth as well. All the ninja from the villages fled, those with a clan went back to being mercenaries while those who were not fought for survival, taking whatever small jobs they could find.
