Gaidel is the father of a girl named Leona. He was a member of the Hakkesshu, and an avatar of water who ran away from his destiny as he did not wish to destroy humanity. Like he did with the rest of the Hakkesshu, one day, Goenitz visited the village where Gaidel, his wife, and Leona were. Goenitz asked for help to resurrect Orochi, but Gaidel refused. Goenitz left, but returned later that night, and activated the Riot of the Blood within Leona, who killed her father, her mother and everyone else in the village.
