Yakumo Fujii

Intro He became Pai Ayanokoji's Wu and companion when a rampaging Takuhi, Pai's demon friend, fatally wounded him. Before he could die, Pai merged his soul with her own, transforming him into a Wu, which in turn made him immortal as long as Pai lives. He can feel pain but he won't die. He will regenerate from any wound, no matter how severe. His father, Professor Fujii made a promise to help Pai become human before he died and Yakumo tries to keep that promise. Yakumo has been shown to have feelings for Pai. Male. Immortal. Yakumo Fujii is just an ordinary high school kid... with a runaway mom and a missing anthropologist father and the resulting need to hold down a part-time job as a "waitress" in a gay bar. Then a mysterious Tibetan girl named Pai shows up, claiming that his now-dead father sent her to Yakumo to "help her become human." Student.
