コーティカルテ・アパ・ラグランジェス

Corticarte in her more common, younger-looking form. The spirit Phoron made a contract with. Corti, as Phoron calls her, is one of the eldest spirits in their world, having six wings, and is known as the Red Elder Spirit — as well as other titles including Crimson Annihilator or Bloody Duchess. She was entranced by the young Phoron's singing voice and thus decided to make a pact with him so he would be hers and hers only. [From Wikipedia]
