Atra, bearing the title "The Heaven's Bow," is an immensely powerful angel credited with defeating over three million demons. She embodies a classic European angelic appearance: a youthful figure with pure white wings, blond hair, and blue eyes, clad in a light blue dress and white flats. Her abilities include the power to resurrect beings, notably demonstrated when she revived Frau after a vampire killed her during a specific narrative event. Sharing heavenly origins with Frau, Atra maintains a companionship with her as fellow beings from the same realm.
