Valkyrie was General Logi's artificial shadow and served as her master's sword and shield. She was fanatically loyal to him. Unlike most Grand Kingdom shadows, she could speak and had her own will.
She was also shown to be very powerful as she defeated Killer Bat, Minotaur, and Saber Tiger single-handedly, and has been a powerful opponent against Blue Dragon countless times. Following Valkyrie's defeat at the hands of Blue Dragon, Logi sacrificed her (at her own will) to summon a Norse mythology-themed shadow called Odin, who is revealed to be his real shadow.
- Chromes 'n May: She fires many fast slashes that destroy her enemy.
- Swirling Bloom: A powerful blast of wind is fired from her sword.
- Rising Nova: She creates a powerful white beam of energy and fires it from the tip of her sword.
