銀朱

Ginshu (銀朱) is one of the four Holy Ones and the High Priestess of the Sakigami shrine. Originally believed to have been cursed by the demon Byakuroku, it was later revealed that their 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). It is revealed that Ginshu is actually not the real High Priestess, but a decoy to protect the real High Priestess, Shinshu. They posses "poison blood" to demons, so when they try to eat Ginshu they die.
