Xu Fu
Lao Ye is the leader of the Xu Fu, and is kept alive through Xu Fu magic until the day he can transfer his body into Shito. He held feelings for Chizuru, but she was already to marry someone else; this resulted in Lao Ye killing her husband-to-be. When Chizuru committed suicide out of grief, Lao Ye revived her as a zombie out his twisted desire to be with her. After Chizuru gave birth to Shito and Lao Ye saw Shito didn't age past his prime, he desired the same immortality, ordering his original Toho to cast the incomplete Corpse Release Spell on him; the end result was an immortal life, but at the cost of a heavily immacipated body. Throughout the generations, Lao Ye had the spell redone and took in Shito's blood to curb the negative effects. In the present day, he is barely kept alive by life-support. He is killed by Touhou.
