Gyaku Kokutris

'''Gyaku Kokutris (Reverse Cockatrice)" is a jutsu used by Odayaka, based on and named after the creature of the same name. Using his sword forged from the remains of one of the beasts, he activates all the powers of the cockatrice within the sword. It extends, becomes deadly poisonous, can release a lethal secretion, and can move fluidly and affect areas larger than it would appear to be. It is even more deadly than the Kokutris it is named for, because it cannot be killed, being a sword, and can be mixed with other jutsu. The side-effect of this, however, is that the user is taken over by the Kokutris' nature slowly. This effect activates immediately upon the usage of the jutsu, and becomes steadily worse. It can take nearly a month to completely rid yourself of the effects caused by ten minutes of usage, and any battle can awaken the beast to a greater degree.
