(Note: 1 VA needed for both roles)

Moderate Summon: Both Valkyries are played by Vishia, who is a major antagonist in Arc 1. She'll have 2 battles in the arc and these two are played in both matches. 

Card Lore: Winged Valkyrie is Winged Little Valkyrie, but grown up into an experienced warrior. She's familiar with all of the Valkyrie tools, but still has room for improvement. Winged Elite Valkyrie is the same character, but now a seasoned veteran of battle. She has mastered all of the Valkyrie tools.

Personality: Winged Valkyrie is tough and confident, but acknowledges she has a way to go. Winged Elite is much the same, but is fully confident in her skills and ready to take on anyone.

Voice: For both Valkyries, I'm looking for a female VA with a more mature voice. Both don't have to be terribly different from each other, but Winged Valkyrie could sound closer to a late teenager, while Winged Elite sounds like a full grown adult.
