The Eidu was a sect of Japanese vampiric monks who worshiped the Master, believing that he had given them the legacy of second sight. In order to became an Eidu, young acolytes, still human, were brought to monks and tortured, making them beg for everlasting life. They finally had their own eyes burnt out before being sired.
In 2001, the Eidu were led by Yuki Makimura and assisted her in her attempt in resurrecting the Master using the Eidu amulet and Xander Harris as a host for the Master. This plan failed and the Eidu were killed off by the Scooby Gang along with Yuki.
