In realityRather, she is actually Kusakabe Misao, the Kusakabe onmyoji that Misuzu admires. She reveals that her two swords were part of Kusakabe's treasures. The swords she has, Onikiri and Kumokiri, in additions to Misuzu's, were once referred as Kusakabe's Seven Swords. After she took the two swords and leaves her clan, the swords that Misuzu has then become Kusakabe's Five Treasures.
She looks down on all the "fragments" and Kakeru except Shiori because only Shiori is strong enough to fight her. She is also the only member of the Black Knights who is actually alive or living without burden. The four subordinate's of George are actually dead and their souls are bounded by her with Larva(the Red Night's creatures) as their bodies. She also sealed their memories they have while they are alive. She also contribute part of her power help keeping the dragon sealed within George. It is hinted that she helps George and his group because she admires and loves him.
