Mortis Sonus

"I can turn you into a statue, a Zombie or simply force your body to rot away. The path you walk is determined by your usefulness."

is a Jutsu developed by extensively studying Princess Tsunade's Creation Rebirth. Called the pinnacle of Medical Ninjutsu, Mortis Sonus uses Koshiro's disgusting chakra to literally control decomposition, either halting it completely or increasing it's speed, in organic matter. Mortis Sonus is it's umbrella term as he has created various jutsu. His Mortis Sonus involves his Wind Release heart as organic specimen require some form of Oxygen or carbon dioxide (Oxygen being it's base). Without wind release, this technique cannot be used.

Usage
Mortis Sonus utilizes various methods of attacks and defenses. However, it's overall function remain stagnate. By infusing his medical ninjutsu with wind release, Koshiro created a new form of deathly arts which increases decomposition within living and nonliving organisms. Koshiro came to a conclusion that all living once living organisms require oxygen in some form. By forcing his chakra into a targets body, he can literally absorb it's oxygen, thus killing it's cells. The loss of cell structure brings about the release of cellular enzymes capable of initiating the breakdown of surrounding cells and tissues. This process is known as autolysis. Within minutes, his targets body is nothing more than a skeleton.

Weakness
Skilled Medical Ninjutsu users can combat his Mortis Sonus through regeneration techniques which create new cells and tissues just as quick as Mortis Sonus destroys, creating a nullifying affect.
