Gentle fists is a type of taijutsu special to members of the hyuuga clan, Unlike the type strong fist gentle fists is about damaging the insides of the opponent rather than the outside.
When a person uses the byakugan they can use gentle fist with
precise movements and deadly accuracy which is mainly needed because the user can see the opponents chakra
pathway and when striking the chakra vessels the opponent
takes damage to their organs also, the chakra vesseles run
through the organs intertwining themselves. When the
byakugan user takes it a little further they can also hit the opponents tenketsu and forcefully open or completly seal the opponents chakra from that point.
