Reincarnation refers to the rebirth of a soul in a new body. With the use of Life essence-related techniques, reincarnation is possible. The only known individual to have been reincarnated is Ryo, whom became known as "Aragami" after his soul was called and placed in the body of a deceased shadow assassin in an ancient ritual, resulting in him becoming the eponymous aragami race.
