Shinobi Compendium: Secret Record of the Origins of Ninjutsu
Here we will discuss how chakra gave rise to ninjutsu, and how this faded into secret folklore.

Descent
To obtain the fruit of the Divine Tree, the Rabbit Goddess descended.

From the moment they assumed humanoid form, mankind had walked a world of strife waging war against one another. The ground was stained with blood, and as if drinking it in, the Divine Tree took root in the earth. In time, the Divine Tree bore a single fruit, and a clan migrated from another world in search of it. They were the Ohtsutsuki Clan. Kaguya, leader of the Ohtsutsuki, ate the Divine Tree's fruit and became the progenitor of chakra, and with that tremendous power subdued the world in the blink of an eye.


 * →↓ The towering Divine Tree. It bore a forbidden fruit that would bestow power to whomever ate it.

Rule
She who ruled alone and coveted all chakra.

Ohtsutsuki Kaguya had brought an end to the turbulent times. Dubbed the Rabbit Goddess, she received the blessings of the people and gave birth to twins.


 * ↓ The birth of Hagoromo and Hamura. Kaguya's chakra had become dispersed.

However, Kaguya ruled by herself and often resorted to cruelty. The Byakugan, the Sharingan, and the Infinite Tsukuyomi—these jutsu wielded by Kaguya were regarded with fear, awe, and reverance by the people. At some indefinite point, the Rabbit Goddess had instead become known as a Demon. Then Kaguya found herself ruled by her own desire to possess all chakra.

Moon
The Ohtsutsuki brothers used the power of Six Paths to seal the Ten Tails.

Kaguya's desire to unite all chakra eventually turned her against Hagoromo and Hamura, her own twins, to whom she had dispersed her chakra while giving birth. Devising a plan to absorb their chakra, she integrated with the Divine Tree and challenged the twins to battle...


 * ↑ The Ohtsutsuki brothers fighting an incarnation of the Divine Tree, the Ten Tails. It seems that they were also doing battle with their mother.

The twins, assuming that the Ten Tails was an incarnation of the Divine Tree, and that it had attacked them to recover the chakra from its stolen fruit, met it head on. After a desperate struggle, they invoked Six Paths Planetary Construction. Transforming it into the moon, they sealed it away.


 * ↑→ The husk of the Ten Tails, the Gedo Statue, was sealed in the moon. Hamura took leadership of the clan and decreed that they would stand guard over the statue.

Ninshu
A power that links individuals brought about peace and order.

Leaving leadership of the clan to his brother, Hagoromo stayed in these lands. Essentially, he believed that chakra was a power that linked everything in the world. Filled with righteous purpose, he set out to spread this message to the people of this land. His teachings became known as Ninshu, the Ninja Creed, and they should have brought about eternal peace and order...

Inheritance
The fate of Ninshu was entrusted to the love of mankind.

Before long, Hagoromo had two children of his own: elder brother Indra and younger brother Ashura. Hagoromo taught them both his Ninja Creed.


 * → Becoming strong thanks to the cooperation of others, Ashura came to understand the essence of Ninshu.

Elder brother Indra inherited all of Hagoromo's power and was a genius from birth. On the other hand, Ashura gained his strength by connecting with others. Hagoromo named the younger brother guardian of Ninshu.


 * ← Recognizing that he was near death, Hagoromo partitioned the power of Ten Tails into the biju.

Reincarnation
From the darkness an endless conflict was orchestrated.

Hagoromo had named Ashura the guardian of Ninshu, earnestly hoping that Indra would continue to support his younger brother. Without the cooperation of Indra, he was uncertain whether Ninshu would survive to be inherited by future generations...

However, there were embers smoldering within Indra that his father had overlooked. It was the perfect opportunity for a certain sneering darkness. That darkness—Black Zetsu—whispered to the heartbroken Indra and stoked those embers into a hellfire.

Ninjutsu
Thus Ninshu became Ninjutsu and man was forced to endure eternal war.

Six Paths
A secret jutsu that created everything from nothing.

Secret Traditions
The vestiges of Shadow and Light Style that became the foundation of many jutsu.
