Hi. Yea, the Byuakugan is one of the three legendary dojutsu along with Sharingan and Rinnegan. It is a Kekkei Genkai that Kaguya herself wielded and was passed down to her son Haruma Otsutsuki while Hagoromo got the Sharingan and Rinnegan. The Byuakugan has superior clairvoyance over both Sharingan and Rinnegan over chakra perceiving and reaction along with giving the user a 359 degree field of view which comes in handy in combat.Alrighty, I believe this would be just for Byakugan, so just give me a summary of what you know of the Dojutsu.
If a target is influenced by a genjutsu would that be noticable by any of the tenketsu points, visually?360 degrees ! The below is from the training with McRazor and should cover most of what you need to know.
Byakugan is one of the fabled dojoutsu, which means that the user has a special set of eyes which give him different abilities. The Byakugan was first seen in the Hyuuga and it was thought that they were the original owner until it was later discovered that it originated from the Otsutsuki clan, namely Kaguya herself. There is a difference in the Byakugan of a Hyuuga and an Otsutsuki in which the Otsutsuki doesn't have the ability to use Gentle fist. With the Byakugan, the user has the ability to see the chakra pathways of the opponent, telescopic vision and a near 360° field of vision, with the only blindspot being behind the neck,
Alright, you covered most of the main points. You're just slightly off about the blindspot, with it being above the first vertebra. Additionally, through the Byakugan thickness is not an issue, as it can see through obstructions and whatnot, making it ideal for your Barney bio! Some thing that has changed since you were last around I believe is the increased tracking capabilities afforded by the Byakugan, where it was undefined before, but now stands as an equal to a 3t Sharingan at x3. Continuing on the comparison with Sharingan, it also enables you to distinguish between clones and real bodies, whilst also allowing you to know where a person's chakra originates from. Although somewhat niche, I like those, and I believe they were used to form a basis in a sense for the Hyuga Tenseigan evolution, the superior evolution.
(Dōjutsu: Byakugan) Eye Technique: The All Seeing White Eye
Chakra: 15 (+5 per turn to keep active)
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 Sannin 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.
