Alastor

He is the Lord of the Crimson Realm to whom Shana is bound. He expresses his will through a divine vessel called the Cocytus which in Shanas case takes the form of a pendant. He is also a fatherlike figure to Shana as he is always aiding her in her confusion. Alastor is considered to be the strongest of all Lords or Denizens even comparable to a god in the Crimson Realm. But even so he tries to keep the Denizens from consuming Power of Existence. Unlike other lords that have a Flame Haze his contractor can perform a method called Tenpa Jyousai which requires a lot of Power of Existence and will manifest him to the world to consume all Denizens around him. This method is his Flame Hazes last resort as it will destroy the Flame Hazes body and kill the Flame Haze.
