The **Bōenkyō Byakugan** (望遠鏡白眼; Literally meaning "Telescope White Eye") is an advanced form of the Byakugan obtained by a handful of the Ōtsutsuki clan. Because of its distinct coloration, it is sometimes referred to as the "Kingan" (金眼; Literally meaning "Gold Eye").

## Overview

A Bōenkyō Byakugan is distinguished from a normal Byakugan by its golden coloration. It is awakened by members of the Ōtsutsuki clan who consume the Byakugan of a fellow clan member, though consuming their own Byakugan is also enough to trigger the transformation. After the initial activation period wears off, the user can freely switch between the two eyes at will. As members of the Ōtsutsuki clan typically sacrifice their retainers when they come of age, turning them into chakra fruits, this is frequently the moment in which many activate their Bōenkyō Byakugan.

The Bōenkyō Byakugan retains all of the Byakugan's generic abilities. Additionally, users of the Bōenkyō Byakugan can temporarily shrink their near-360º vision in order to greatly project their vision, allowing them to see hundreds of thousands of miles away. As the Bōenkyō Byakugan retains the ordinary Byakugan's x-ray vision and ability to see chakra, this essentially permits the user to see anything they want from tremendous distances at the loss of their near-360º awareness while this ability is activated. Some Bōenkyō also grant their users unique abilities. Isshiki's granted him both Sukunahikona, an ability that allowed him to shrink down any matter within his line of sight instantaneously, and Daikokuten, an ability that allowed him to store shrunken objects in a pocket dimension until he was ready to use them.

Like any dōjutsu, Bōenkyō Byakugan can be transplanted into a non-Ōtsutsuki or one who has not yet awakened the eye. In these cases, the Bōenkyō becomes a paler yellow and gains a distinct pattern, resembling a dharma wheel, as was the case of Isshiki Ōtsutsuki. Non-Ōtsutsuki who obtain the eye in this way can find their chakra significantly strained. Even for Ōtsutsuki clan members, use of the eye is heavily demanding of their chakra, meaning members who have consumed chakra fruits are more successful at using it for long periods of time.

## Trivia

* Bōenkyō Byakugan was inspired by Seireitou's original so-called "Bankakyō Byakugan" (万華鏡白眼; an obvious misspelling of 万華鏡 (*mangekyō*) from the Mangekyō Sharingan) on the Naruto Fanon Wiki. It was originally conceived of by Seireitou as an advanced Byakugan, comparable to the Uchiha clan's Mangekyō Sharingan, achieved when a member of the Hyūga clan reached nirvana.
* Bōenkyō Byakugan are known to glow in the dark, similar to the Sharingan.
* For some reason, the awakening of the Bōenkyō Byakugan also triggers a golden coloration in an Ōtsutsuki clan member's Rinnegan. This new coloration does not seem to confer the Rinnegan with any new abilities and appears to be nothing more than a side effect of the awakening.
