Ancient Shinigami Arts
The Ancient Shinigami Arts are an extremely powerful form of ancient magic that allowed the shinigamis to easily rule the Universe eons ago. Only the king of the shinigamis can use this immensely powerful magic. This magic falls under two classifications, which are Death Magic and Life Magic.
Death magic allows the user to kill any living thing they desire in an instant, they can completely drain and absorb the life force of all living things. By draining and absorbing the life force of their victims they also drain their ki and become even stronger then before. Death Magic can easily kill weaklings, but it takes longer to kill those who are exceptionally strong individuals. Shi has fully mastered this form of magic. Some techniques Shi uses with Death Magic are listed here.
Death Wave - Shi releases a massive wave of death magic from his body that pretty much instantly kills anything within his range.
Death Orb - Shi launches a black orb from his hand that destroys anything in its path.
