One of the four Holy Ones and the High Priestess of the Sakigami shrine. He was cursed by the demon Byakuroku to die and be reborn every day. 

Ginshu is actually asexual, but is referred to as a Princess anyway. It is revealed that Ginshu is actually not the real High Priestess, but a decoy to protect the real High Priestess, Shinshu. He possesses "poison blood" to demons, so when they try to eat him, they die.

Originally believed to have been cursed by the demon Byakuroku, it was later revealed that his spirit was in fact placed within Byakuroku's body, as an attempt by Bonten to preserve them both (after a battle that would have cost both their lives).

Before he was cursed with his ageless and genderless body, he was, in fact, male. Because of the shrine's tradition, he was dressed and referred to as though he were female.
