This jutsu is the ultimate Gentle Fist jutsu,it attacks all the target's tenketsu and not only destroys his chakra but with striking some points that are clearly seen with the byakugan drains the target's life force even to the point of killing them.If killing them doesn't succed they cannot use any type of chakra,including elemental chakra or doujutsus for a very large amount of time,leaving them with only taijutsu to defend themselves,and sometimes not even that.
