History
In distant time, mankind fought countless battles, leaving the earth soaked in blood. A tree would grow from the blood of the deceased, getting attention of the Ōtsutsuki clan, as it bore a fruit of great power. Princess Kaguya, leader of the clan, would later consume the fruit to transcend and bring peace using her unrivaled power. Seen as a deity by people and called the, Kaguya settled down amongst them, as she would eventually get pregnant and bear twin sons. However, Kaguya had grown despotic, the power having clouded her judgment, resorting to control mankind by force, something which would change her public image of a benevolent goddess into that of a. In a fit of jealousy that her children had inherited her chakra, Kaguya merged with the Shinju to turn against her own sons in a form of the monstrous Ten-Tails. After a fierce battle, with Hagoromo and Hamura standing victorious, the tailed beasts were made from her chakra, with her body sealed to form the core of a celestial body that would be known as the Moon. Hamura succeeding leadership of the clan later departed along with the rest of the Ōtsutsuki to the moon in order to guard their late princess (something they weren't aware of, thinking it to be the Shinju), while Hagoromo would stay in order to spread chakra to the humanity and teach them the concept of Ninshū. The clan was separated into two parts, the Main family and the Branch family, the clan inhabited the moon for a thousand years, the descendants of Hamura sealed their eyes within the Energy Vessel the Tenseigan, a giant orb accumulating tremendous power. The Branch family misinterprets Hamura's celestial decree, if they determined that mankind were using their chakra for evil after a millennium, they would unleash that power upon them. The clan killed off each other in a civil war.

One millennium later, Toneri Ōtsutsuki, a direct descendant of Hamura and sole survivor of the extinct clan, would return to undo what his ancestors had made, planning to destroy humanity by having the moon collide with the earth, as a punishment for humans abusing chakra for militant purposes, and also specifically targeting Hinata Hyūga to revive his clan and continuing Ōtsutsuki bloodline.
