A long time ago a god tree exist, around it the land is fertile. The humans waged wars for this land. Countless eons had passed the humans are still waging war against each other. The reason forgotten and then, one day a fruit on the god tree is seen. A princess decided she would end all wars. She alone climbed the god tree.
The princess wasn't seen for a long time, days had passed, and everyone thought the princess had died. Until one day the princess flew down like an angel and everyone was in awe. Day's later new wars were waged. The rulers wanted the hand of the princess. But, no one wants to back down until the princess showed her powers. One by one she defeated these rulers, she acquired their army, defeated anyone who opposed her until she achieved piece.
Centuries had passed. The princess who ate the fruit bore twins. These twins cultivated chakra during the time in her womb. The god tree felt the separation of chakra. And created a beast to retrieve and combine his chakra into one.
Unknown to everyone the god tree is sentient. It was waiting for the princess to succumb to old age and retrieve its chakra but with the separation of chakra into her children that plan was destroyed. And it needed to be fixed fast before it truly spreads.
The princess learned of this and fought the beast, She is stronger than the beast. The beast is mindless unlike the sentient god tree at the end of their fight she sealed the beast inside her. Years passed and her son grew into adulthood the twin tried to help fixed the destruction of the planet from the fight between the beast and their mother. They also thought humans their way, "Ninshu".
As the time passed the mindless beast corrupted the mind of the princess with its mission. The corrupted princess became one with the beast; the beast being pure chakra didn't have flesh. And as they became one the princess became the flesh of the beast (Gedo Mazo). And a new war was started.
The twins learned of what happened to their mother. They knew their mother is stronger than them alone. But, the twin always fought together and with teamwork they defeated their mother separated her from the beast and sealed her inside the spherical object that became the moon. The beast was sealed inside the older child and the younger child became the guardian of the body.
Peace was once again retained for centuries. But the brothers have succumbed to age. The younger disappeared in the annals of history. The older became a myth; the beast was separated into 9 beings.
Thousands of years passed, and once again the continent is plagued with war. The teaching of Ninshu, became Ninjutsu. One man has dreamed of peace, he started a village where everyone can come together, other nations followed suit but war still didn't disappear. Before it was a fight for clan, now it is a fight for their village. But, the man still hoped for peace. After the death of this man; 3 major wars happened at the end of the 3rd major war the child of Prophecy was born. This child was prophesied to bring peace. The biggest war in history happened, the beast and the princess reappeared and humanity combined together to protect the child, but the child brave through and fought into the front line with the help of the villages and his friend. He once again sealed the princess inside a new moon but this time in another dimension, during the course of the war the child achieved godhood but being a war hero no one has thought much of it. After 30 years of being a leader of his village the child disappeared.
