Hamura Ōtsutsuki

was the son of Princess Kaguya Ōtsutsuki‎‎ and the twin brother of Hagoromo Ōtsutsuki. Alongside his brother, he was one of the first humans to be born with chakra.

Background
Kaguya Ōtsutsuki gave birth to two twin sons, the first humans to be born with chakra. He is the younger twin. When Kaguya realised both Hamura and Hagoromo also had the ability to wield chakra, Kaguya as the Ten-Tails tried to forcibly reclaim her chakra. Eventually, Hagoromo and Hamura succeeded in defeating and sealing her within Hagoromo. After Hagoromo created the tailed beasts and extracted the Demonic Statue of the Outer Path from his body to seal it onto the moon, resulting in his death, Hamura and the rest of his clan departed to the moon, in order to guard his mother's sealed remains.

Personality
As he chose to seal his mother, ending her reign of terror, Hamura was a man who believed in peace and freedom. Also, he was very dutiful, as he remained on the moon to guard Kaguya's sealed body.

Appearance
Hamura was a tall man with featureless white eyes and horn-like protrusions on his forehead inherited from his mother. He also had no eye brows and long light-coloured hair with bangs combed to the left, a single chin-length lock which hung from the right side of his face. He wore a light, full-length kimono with a pattern of six black magatama around a high collar and dark pants. He had his sword in its sheath strapped to his left hip. He also had a dark crescent-moon representing Yin mark on his left palm.

Abilities
One of the most powerful figures in history, he was able to defeat the Ten-Tails in battle together with his brother. In battle Hamura wielded a sword with presumable proficiency as well as a shakujō. He was also noted to have inherited his mother's powerful chakra and wielded the Six Paths Yin Power in his left hand that he used in combination with Hagoromo's Six Paths Yang Power to seal the Ten-Tails into the core of the Chibaku Tensei.

Byakugan
As a wielder of the Byakugan, Hamura had access to the standard abilities of the dōjutsu such as: a near 360° vision (with the exception of a small blind spot at the upper thoracic vertebrae), x-ray vision, and the ability to see the chakra pathway system.

Legacy
Before going to the moon, his bloodline continued which eventually would become the Hyūga clan and the Byakugan was also passed down to them. One of his descendants continues his mother's legacy to punish mankind for abusing chakra and continue to have wars.
