Brunhilde

"I will show no mercy to one who would incite a rebellion in the Empire, even if you are my brother!"

Goddess of War, protector of the once throne of the Chief God Odin—Valhalla. Blessed with the blood of the founder Loki and that of one of his queen goddesses, she is considered an absolute force of nature by the anti-Asgardian demon forces now that her own power and spirituality have been unlocked by a certain senator. Brunhilde is Vali's half-sister, born into the Asgardian imperial family from a different mother. Unlike Vali and his strong demonic blood, she inherited genes from a progenitor goddess, granting her a great wealth of divinity. A gentle soul, her most fervent wish is peace for the commoners of the Asgard Empire. A wish she is willing to grant at the point of her divine spear. She has many admirers among the other knights as she was raised as a prim and proper young lady.
