The Tenseigan, also known as the Energy Vessel (エネルギー体, Enerugī-tai), is a sacred treasure of the Ōtsutsuki clan, it had been used for millennia to seal the clan's Byakugan to combine their power. It is also used to collect and amplify natural energy, with the clan using the vessel as an energy source to power everything on the moon, including the countless autonomous puppets that served them. As such, it has the power to create massive blasts of chakra that can wipe out entire armies in a similar manner to the Tailed Beast Ball, and could be used to give a user the Tenseigan when they have the Byakugan implanted into their own eyes. It is said that the vessel can only be touched by those with the "undiluted chakra of Hamura," or the Ōtsutsuki and Hyūga clans, both of which are Hamura's descendants.
The Tenseigan itself consisted from two separated parts, its case and the main content. The case its cauldron-shaped structure made from golden, which currently chained and mounted inside the Hamura's shrine. The main content is a sun-like orb eye-like structure with yellow hexagon-shaped pupil surrounded by an orange-yellow flower-like iris, which currently stored inside the core of the artificial sun and protected with some huge pieces of metal bars and guarded by a large number of puppets. In the past, its somehow placed and mounted in a wheeled tower structure with an emblem resembling Surya Majapahit emblem carved in the front of the tower.
The vessel was later destroyed by Naruto and Hinata via their combined effort. When the vessel was damaged, it began to flicker, and ultimately exploded, disintegrating into countless Byakugan. When it completely broke, the artificial sun inside the moon disintegrated and all living things inside the Moon ceased to exist, however, the Moon would only stop to move temporarily.
Trivia
- The emblem carved in wheeled tower structure where the Tenseigan mounted in the past resembling Surya Majapahit emblem. The Surya Majapahit (The Sun of Majapahit) emblem is the emblem commonly found in ruins dated from Majapahit era. The emblem commonly took form of an eight-pointed sun ray with rounded part in the center depicting Hindu deities. The emblem might took form of a cosmological diagram haloed by typical "Surya Majapahit" sun rays, or simple circle with typical sun rays. Because the popularity of this sun emblem during Majapahit era, it is suggested that the sun emblem was served as the imperial symbol or emblem of the Majapahit empire. Its likely also the reference of Tenseigan power as artificial sun.
