Valkyrie is a recurring supporting character presented as an adult female with waist-length blonde hair and blue or green eyes. She typically wears revealing armor that exposes her midriff and wields a lance as her primary weapon, demonstrating combat proficiency especially in monster slaying.

Initially haughty and arrogant, she claims divine selection for fighting evil. Her introduction involves competing to join Fighter's party. A physical confrontation featuring mutual groping with Hunter shifts their dynamic from hostility to partnership, prompting them to form their own independent party. This encounter creates a bond, with Hunter's teasing noted to have "melted her heart" and given her positive feelings.

Her relationship with Hunter evolves into a significant romantic and physical connection, progressing from bickering to a Slap-Slap-Kiss dynamic. Confirmed intimate encounters occur in the OVA special episode. Their partnership remains consistent; they collaborate on adventures and reappear together in later episodes to assist the main party during critical battles like confronting the final boss Demon Lord Deathgeld.

Despite her noble aspirations, Valkyrie maintains high expectations for travel living standards, contrasting with Hunter's survivalist approach and initially causing friction. This difference, alongside their divergent personalities, contributes to their mutual attraction and ongoing partnership. Her character development across all media primarily revolves around this relationship rather than individual backstory expansion. She appears recurringly alongside Hunter, not as a sustained focus within the main protagonist group.
