During Ten Desires, Yoshika Miyako attempts to stop the heroine from entering the mausoleum. It reveals she is Seiga's servant.
Yoshika is not very smart, but she is loyal to her master, Seiga. Because she is a Jiang Shi, she lacks the flexibility and agility of a normal human. Her half-rotted brain causes this problem. Despite being a sort of zombie, she takes good care of her skin.
As Seiga's servant, Yoshika assists her during the battle between Seiga and the heroine.
