The ninja world and all the countries in the world were trembling.
The 4th Hokage Nori Hisamatsu died trapped by the other four Kages and after a bloody battle the 4th Hokage killed before his death the 3rd Raikage, the 4th Kazekage, the 3rd Mizukage and Tsuchikage and an army of more than fifteen thousand ninjas.
Greatly diminishing the powers of villages of Iwa, Kumo, Suna and Kiri.
After this legendary fight the devastated valley was renamed Red Valley, the title of ninja god was given to him and spread throughout the world.
Because of the loss in power of the great nations except konoha, many frictions occurred between the various large villages, the small nations formed an alliance opposing the great nations weakened by the third war and the loss of their powerful Kage, thus the 4th great ninja war broke out.
This war was bloody, children were daily sent to the battlefield to make up for the lack of manpower, but in this war many men made their reputation as, Dai the jade tiger, Kakashi sharigan and Minato Konoha's Yellow Flash.
But all this does not interest us at all, on a blue planet in another universe, in a battlefield on the site of a burnt village where lay the corpses of humans and men with the heads of leopard, monkey, oxen, a pretty little boy with red hair, dressed in an old black Kimono, the torso covered with bloody scars suddenly opened his eyes taking a deep breath.
And as the wounds on his torso healed at a visible rate he murmured unconsciously.
"Where am I?"
