Pai is the last of the Sanjiyan, a race of people with three eyes. She has hopes of becoming human and ending the endless line of pursuers hoping to hunt her down and take her powers for evil ends, but disaster happens when Pai seeks out Tokyo high-school student Yakumo to alert him of his father's death. In order to save Yakumo from being lost forever, she has to absorb his soul into her own body, and now she has to protect herself even more carefully from the demon spawn that hunt her because if she is killed, so is Yakumo. Now undead and immortal, he protects Pai against attackers as they search for the tools to make both of them human. ~ Cammila Albertson, All Movie Guide
