Madame Horos

Swami Laura Horos, commonly referred to as Madame Horos (マダム＝ホロス), is a fraud who posed as Anna Sprengel.

Background
At some point in the past, Madame Horos managed to steal the body of Anna Sprengel and assumed her identity, impersonating her for over a century onwards.

Coronzon Arc
During the events surrounding the Ceremony of Mo Athair, Madame Horos approached Takitsubo Rikou as Anna Sprengel, offering her a means to help Hamazura Shiage, but actually planning to kill him while using her. Her attempt was ultimately thwarted by the revival of the recreated Dion Fortune. After Coronzon's defeat, Madame Horos appeared before the dying Aleister Crowley, still posing as Anna Sprengel, but was ambushed by Aiwass who swiftly dispatched her and restored the real Anna Sprengel to her body.
