Pathogen: Production Failure

Inari can create a special pathogen engineered toward attacking the cells in a victim's body. In normal people, physical energy, a significant component in the molding of chakra, is produced naturally by the person's cells. It is an energy present in every living being's cells. This pathogen is designed to attack the cells of its victims and shut down production of physical energy, making it difficult and eventually impossible for a victim to have the necessary amounts of both energies needed to form chakra. This also has adverse side effects on the victim which causes their muscles to slowly lack the energy needed for even basic motor skills.
