Hamura Ōtsutsuki

was the son of Princess Kaguya Ōtsutsuki‎‎ and the 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 sons, the first humans to be born with chakra. When Kaguya realised both Hamura and Hagoromo also had the ability to wield chakra, Kaguya created the Ten-Tails to forcibly reclaim her chakra. Eventually, Hagoromo and Hamura succeeded in defeating the Ten-Tails and Kaguya by sealing them both away. It is unknown what became of Hamura after this point.

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.

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 he carried a staff and a sword which he was presumably skilled at wielding. He was also noted to have inherited his mother's powerful chakra.

Dōjutsu
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.

Fūinjutsu
Along with his brother, he was able to use a powerful sealing technique to seal the Ten-Tails inside Hagoromo.
