He is the Lord of the Crimson Realm, to whom Shana is bound. His will is expressed through a divine vessel known as the Cocytus, which, in Shana's case, takes the form of a pendant. He serves as a fatherly figure to Shana, always there to assist her when she is bewildered.
Alastor is regarded as the mightiest among all Lords or Denizens, comparable even to a god within the Crimson Realm. Despite his immense power, he endeavors to prevent Denizens from consuming Power of Existence. Unlike other lords who have Flame Hazes, his contractor possesses a method called Tenpa Jyousai. This technique demands a significant amount of Power of Existence and results in Alastor manifesting into the world to consume all nearby Denizens. It is the ultimate measure for his Flame Haze.
