The Hyuga Clan

The Hyūga clan (日向一族, Hyūga Ichizoku) is one of the four noble clans of Konohagakure. Some 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.
