Aureole Omega

Aureole Omega is the Area Guardian of the Cherry Blossom Sanctuary in the Great Tomb of Nazarick in Overlord, and the leader of the Pleiades Seven Sisters, the tomb's battle maid squad. She has charge of the teleportation gates throughout Nazarick, and she guards the Staff of Ainz Ooal Gown in the sanctuary. She appears as a young girl, no different from a human, and dresses in the traditional attire of a miko, a pair of red hakama with a white haori. Her sisters describe her as rational and high spirited, and she speaks calmly, in a gentle voice. She is the one human NPC of Nazarick with eternal life, and she is usually the one who knows where each of the Seven Sisters is.
