Fifth Shinobi World War (GD)

The Fifth Shinobi World War (第五次忍界大戦, Daigoji Ninkai Taisen) is the fifth world conflict, involving a majority of the world's forces, including those previously uninvolved for the most part in world wars. An ongoing conflict, recently three sides have been drawn going head to head. The conflict is between the Shinobi Union II, the Kaguya's legacy and the Saimei's Empire and takes place about thirty-five years after the Fourth Shinobi World War in the Golden Darkness Shinden.

Preparations for War
A war that was in the works ever since the fall of Kaguya in the Fourth Shinobi World War. Zetsu had created many plans to make sure Kaguya had succeeded and even though Naruto and others had stopped his most obvious plan, he still had more tricks under his sleeve. Awakening his hundreds of dormant doppelgangers all over the globe and even on the moon itself shortly before being sealed alongside his mistress, another plot for the awakening of Kaguya came back into play, underneath the noses of the Shinobi Union.

Using the underground, Gisō, the new Black Zetsu in charge, contracted many criminals and terrorists to his side. He also weakened other villages slowly, forced others to his side and more. While Naruto could sense negative emotions, there were many other conflicts that appeared and kept the true goals of Zetsu hidden from even the great hero. Zetsu grew in power hidden in the underground, starting events such as Toneri's moon dropping, keeping the Shinobi Union busy and under the belief they had effectively defeated most conflict.

After bidding their time for more than three decades, Gisō found the perfect time to strike. While members of the Shinobi Union began to investigate the underground and thus Gisō himself, they were too late to start the war's outbreak. With the fall of to a "sudden" Zetsu outbreak, the Fifth Shinobi World War had technically begun.
