The **Tenseigan** (転生眼, Literally meaning: Reincarnation Eye) is a heightened stage of the Byakugan, similar in principle to the Rinnegan. It is only seen very rarely in the Ōtsutsuki Clan, and even more rarely still, in members of the Hyūga clan. Rivaling the Rinnegan in power, the Tenseigan stands apart from the "Three Great Dōjutsu" (三大瞳術, *San Daidōjutsu*, Literally meaning: Three Great Eye Techniques). It is known among the Ōtsutsuki as the **Eye that Sees Despair** (見絶瞳, *Kenzetsugan*).

## Background

The Tenseigan is a dōjutsu that originally manifested in the Ōtsutsuki of old, seeming to begin with Hamura Ōtsutsuki when it evolved from his Byakugan. The eye is unique to the Ōtsutsuki and Hyūga clans, in the way that the Rinnegan is unique to the Ōtsutsuki and Uchiha clans.

The Tenseigan rarely manifests in Ōtsutsuki clan members. While Hamura was not the first to acquire this eye, the easiest way for an Ōtsutsuki or a Hyūga to manifest the eye is to transplant the eyes of a member of the opposing clan: Ōtsutsuki can manifest the Tenseigan via transplanting a Hyūga's Byakugan, or a Hyūga can acquire it by transplanting the Byakugan of an Ōtsutsuki descended from Hamura. This will awaken the Tenseigan within their eyes, by recreating chakra similar to Hamura Ōtsutsuki.

However, Ōtsutsuki can and have awoken these eyes naturally. Hamura is not the first of the Ōtsutsuki to manifest the Tenseigan; similarly to how the Rinnegan did not debut into the world with Hagoromo. In older Ōtsutsuki legends, the Tenseigan is a revered eye, spoken of which as much acclamation as the Rinnegan itself. The first known Ōtsutsuki to possess the Tenseigan was a powerful Clan leader, whose name would go on to be lost to history. His moniker, however, would survive on ancient, semi-destroyed stone tablets on the Ōtsutsuki homeworld. This Ōtsutsuki was the "White Yaksha" (城夜叉, *Shiroyasha*). Together with his comrade, the "Heavenly Yaksha" (天夜叉, *Tenyasha*), the original Ōtsutsuki to manifest the Rinnegan in its many forms, the two would originally try to unite their extraterrestrial clan.

Other Ōtsutsuki have manifested these eyes without recreating Hamura's chakra as well: Kisshōten Ōtsutsuki is a half-breed that manifested these eyes after her Ōtsutsuki manifested. It is believed that, when a Byakugan reaches levels of insight that it begins to allow the user to perceive Cosmic Energy, the Tenseigan awakens naturally.

## Abilities

The abilities of the Tenseigan are the most distinctive among any known dōjutsu. Much like a fully-evolved Rinnegan (i.e. one with tomoe), the Tenseigan dōjutsu retains the abilities it once-held as a Byakugan, however, they are vastly heightened. The user's visual acuity surpasses the Rinnegan and Byakugan by far — to compare the two to the Tenseigan is to compare the distance between worlds. The distance to which one can see with a Tenseigan varies by user, as it does with the Byakugan, however, the limit of the Byakugan is paltry in comparison to the Tenseigan itself; a Tenseigan user has been known to see vast distances, halfway across what one could consider a country border.

The most keen ability of the Byakugan, to bore into a target's body visually and see the Chakra Pathway System remains; a Tenseigan user can now bear witness to the existence of the chakra limiters, the Eight Gates, with the pinpoint accuracy of a master marksman. Capitalising on their ability to see the Pathway System and Eight Gates, a skilled Tenseigan wielder can completely destroy an opponent's ability to wield chakra, disabling them and rendering them unable to mould the critical energies ever again. The Tenseigan comes with the innate ability to perceive natural energy in its purest state — normally a trait only usable by a Byakugan user that has mastered Senjutsu. This is referred to as witnessing the **World Flow** (界流, *Kairyū*).

In spite of these already fearful abilities, the Tenseigan possesses tricks that the Byakugan never could. While being the Byakugan's only evolution, the Tenseigan is not in the same class as the Mangekyō Sharingan, and are in fact, the eyes of a Sage. This, however, holds a different meaning for the Ōtsutsuki than it does for typical shinobi. The Tenseigan possesses the natural ability to absorb, store, and manipulate Cosmic Energy while it is active. By combining it with their chakra, an Otsutsuki is capable of utilising the Tenseigan's devastating abilities. The most straightforward method to use Cosmic energy is the **Tenseigan Chakra Mode** (転生眼チャクラモード *Tenseigan Chakura Mōdo*), a heightened transformation unique to Tenseigan wielders by virtue of possessing these blessed eyes.
