Byakugan Body

The Byakugan Body is an offensive and defensive ninjutsu technique. Where Nobuyuki Hyūga breathes out mist from his mouth surrounding his body. He then uses his chakra to wrap around his body condensing the vapour into an armour style around him. He keeps the water in place by what can be understood as tying it down to his tenketsu points. Where Nobuyuki Hyūga chakra would hold it in place. It especially works as he has strong and powerful chakra reserves.

This body armour may be viewed as weak, but it is able to withstand multiple wind release attacks or any other nature type - excluding lightning. If an attack was able to remove parts of the liquified armour, then the water particles in the surrounding atmosphere would just condense back around Nobuyuki patching up any exposed parts.
