Kawa Ken - Skin BondEdit
Kawa Ken is an equally disturbing expansion of Kawa Kamen. By flowing chakra through two sections of flesh, the user is able to bind them together. If the user can manage to get a hold of a pair of enemies, he can bind them together at the flesh. Unlike in Kawa Kamen, since both of them would be living, the bond would be permanent unless they cut themselves apart or had a simple surgical procedure done to separate them. It can also be used to perform an impromptu skin graft or similar procedure.
