The Blood Pact Hunter

At her Bloodline Awakening Ceremony, elite demon-hunter trainee Luna Nightshadow is found to have "no bloodline." Her fiance, Marcus Black, breaks off their engagement in front of everyone, and her rival Willow Green humiliates her. Her teacher, Alfred, reveals the truth: Luna in fact carries the Twin-God bloodline (Wolf God and Vampire Progenitor), a once-in-a-thousand-years lineage that the Green family has sealed away. After her teacher is killed, Luna travels to the Eternal Night Canyon and, through countless brushes with death, awakens her Twin-God bloodline. She returns for revenge, stripping her enemies of their bloodlines and freeing her sealed parents. But when the Norse gods break their seal and descend, Luna uses her life-burning power to slay Odin, and is in the end saved by the Spirit of the World Tree.
