The Hyūga clan is one of the four noble clans of
Konohagakure in which all members born into
this clan possess the Byakugan, a kekkei genkai
that gives them extended fields of vision and
the ability to see through solid objects and
even the chakra circulatory system, amongst other things, and expel chakra from any of the
tenketsu in their body. the kekkei genkai
Byakugan meaning "All Seeing White Eye" is the
dōjutsu kekkei genkai of the Hyūga clan. It is
one of the Three Great Dōjutsu along with the
Sharingan and the Rinnegan.
Those who inherit the blood of this clan have almost featureless white eyes. When the
Byakugan is activated, the user's pupils become
more distinct, and the veins near their temples
bulge. It also appears that unlike the other two
great dōjutsu, all members of the clan possess
and can use the kekkei genkai from birth, as opposed to needing to awaken or not inheriting
it at all. Abilities
--The first ability of the Byakugan gives the
user a near 360º field of vision, except for one blind spot at the back of the neck above the third thoracic vertebra. Upon activation, the wielder is granted an automatic 50 metre field of vision around themselves. This improves further if you become a master.
--The second ability is being able to see
through solid objects, as well as some degree
of telescopic sight. The distance and the
degree of telescopic sight varies from person
to person, and can be improved. However, the
Byakugan cannot see through certain barriers. --The third and one of the greatest uses of the Byakugan is the ability to see chakra, chakra flow, the chakra circulation system inside the body with great detail as well as the colour of chakra. It is from this particular ability that the Hyūga Clan are able to employ their ultimate attack style: Gentle Fist.
--Unlike the Strong Fist, which is focused on
external injuries, the Gentle Fist style focuses
on internal injuries. Each strike, when placed
correctly, strikes along the chakra pathway
system, which is the network of vessels that carry chakra. This network is closely intertwined with the functioning of the body's organs, and so, when the chakra pathways take damage, the organs suffer as well. There is no defence against the Gentle Fist, since one cannot train one's internal organs to become stronger. The only possible defence is to stop the Gentle Fist's hits from connecting. Like the Sharingan and Rinnegan, the Byakugan's ability to see chakra and its flow allows the user to detect chakra sealed barriers as well as determine when genjutsu is being used. It was shown in the anime that the Byakugan
can also discern a transformation and a real
person using the eye's ability to see chakra.
