A parasitic assassination technique that Sakon and Ukon can use with their level 2 cursed seal active, and their unique kekkei genkai. With the power of chakra, he disassembles his body down to a cellular, and even to a proteinic level, and enters the enemy's flesh. This cruel technique gradually corrodes the inner bodily cells of those he merges with, and death ensues. Though any injuries the host body receives are also suffered by the user, leaving them susceptible to any of the host's suicidal attempts.
Until Kiba's unhesitating attempt to commit suicide to take Ukon with him, Ukon claimed that this technique's greatest strength is that none of his previous victims dared attack due to fear of harming their own bodies.
