Vanir Gullveig is the Witch from Abore, Monica's village. She is the main antagonist in the Monica Arc but she's the weakest antagonist to be introduced in this series. Vanir is a ruthless witch without any consideration to human lives, she uses them like her own puppets and feels nothing from taking lives. She's thinks of herself highly, even though her powers are quite low in comparison to most characters in the series, but when cornered or desperate, she would plea for help. Vanir is the witch who caused Monica's best friend to die, and is responsible for killing many of the villagers there, as well as killing a couple B-Class WHs when they arrived at her village. When she discovers Tarras and Xing, she reveals herself on a flying broomstick, which is why Tarras was unable to detect her with Earth Scan, and controls the villagers to surround and attack them, but they were easily defeated by the WHs. She gets knocked off her broomstick by Tarras' Earth Cannon and Rain of Earth. Vanir decides to use her ability to control Tarras and Xing. When Tasha and Halloween emerge to confront her, she uses Tarras' Lance of Gaia to attack Tasha but the attack was stopped by Halloween. She continues to order Tarras and Xing to attack Tasha and his supporter. Vanir manipulates Monica into grabbing Halloween's sword that was dropped and having her thrust it into Tasha's back. When Monica's power is awakened, her threads was ineffective against Xing and Monica. Tasha uses his Battlefield to destroy her supporter, leaving her vulnerable. Vanir pleads to Monica to save her as a fellow witch, but is ignored. Then she gets sent to Alcatraz, the witch prison.
