Iwagakure Kinjutsu

This kinjutsu, which was traditionally passed down through generations in Iwagakure, allows the user to knead chakra into materials. It is rumored that the mouths on the user's palms and chest are the result of using this technique.

Rakudo received the knowledge of this technique in his adventures around the world and uses it in conjunction with his Explosion Release to infuse explosive chakra into clay, creating a unique fighting style with explosive clay.

As of recently, Rakudo has performed the necessary operation on the right hand on a man named Hazama.
