Description: The kekkei genkai intrinsic to both the Hyūga and Ōtsutsuki clans—descendants of Kaguya Ōtsutsuki. Those who possess this dōjutsu have it manifested as eyes with featureless white irides and no visible pupils. And when activated, the pupils become more distinct and the veins near their temples bulge. To activate the dōjutsu, Hyuga but not Ōtsutsuki clan members are initially obliged to use a rather long and specific sequence of handseals: Horse → Tiger → Boar → Hare → Rat → Dog → Horse → Dog → Hare → Rat → Boar → Snake. But once activated, the dōjutsu user is endowed with a range of skills.
To start, an activated Byakugan gives the user a near 360º diameter field of vision bar one blind spot at the back of the neck, above the first thoracic vertebra. Its vision can penetrate through any solid objects or obstructions, and likewise remains unaffected by blinding interferences. But that being said, certain barriers and the like may distort its perception. In addition, it is able to follow high-speed movements, which enables those with this dōjutsu to analyze their foes' actions and better react to them. The Byakugan is also able to see chakra to a higher degree than the Sharingan and ergo, identify where a person's chakra signature originates from. Beyond that, it can discern certain types of clones from the real person. And its ability to see chakra is in fact so acute that those who possess this dōjutsu are even able to see the chakra pathway system and the 361 tenketsu that comprise it. The Hyūga clan has gone so far as to develop their unique Gentle Fist style in order to capitalize on this particular ability.
Note: Hyuga clan bios of at least Jonin rank become able to passively activate their dōjutsu upon one month having passed since Gentle Fist training concluded. Ōtsutsuki bios never need to expend a move in order to activate it.
Note: While traversing the NW, bios with activated Byakugan are able to see up to two 2 adjacent landmarks away while those of sage rank can see as far as three away, but this doesn't extend beyond an ocean landmark.
