The Sanjiyan-Unkara, a legendary race of three-eyed immortals, have
been reduced to their final survivor. With his dying breath the
archeologist studying them sends the last one, the childish Pai, to
find Yakumo, the son he had left behind in Japan, who is to help her
become human. Though initially put off by the situation, Yakumo finds
himself dying to protect Pai from harm – and then his story truly
begins. When Pai opens her third eye her Sanjiyan personality takes
over, making her a powerful enough sorcerer to bring Yakumo back to
life as a Wu, an immortal zombie linked to the fate of Pai; when she
becomes human, so will he regain his humanity, but should she die, so
does he. Attacks by demons seeking the Sanjiyan's immortality soon
prove that Yakumo cannot return to his normal life, so he eventually
agrees to help Pai. While seeking a statue necessary for the ritual
that will make her human, Pai and Yakumo get caught up in a scheme to
resurrect Kaiyanwang, the godlike individual responsible for the
destruction of the rest of the Sanjiyan. Yakumo also gradually comes to
realize the he is developing feelings for Pai, feelings which only grow
stronger when she disappears for four years after a climatic fight only
to reappear under a new identity, suffering from amnesia.
