Ōtsutsuki Clan

The is a clan originating from another world, having arrived to the earth about 1,000 years ago.

History
A millennia ago, 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 "Rabbit Goddess", Kaguya settled down amongst them, as she would eventually get pregnant and bear twin sons. However, Kaguya had grown despotic, 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 demon. On the brink of insanity, Kaguya merged with the Shinju to turn against her own sons in a form of the monstrous Ten-Tails, to take back chakra she had given them. After a fierce battle, with Hagoromo and Hamura standing victorious, the Tailed Beasts were made from her chakra, with her body sealed to form core of a celestial body that would be known as the Moon. Hamura later departed along with the rest of the clan to the moon to guard his mother's remains, while Hagoromo would stay in order to spread chakra to the humanity and teach them the concept of Ninshū.

Millennia later, Toneri Ōtsutsuki, a direct descendant of the 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.
