Setsuna is a demi-human from the Ice Wolves tribe. She has humanoid features, including silver hair, blue eyes, and prominent lupine ears. Her forearms and legs are covered in gray and white striped fur. Driven by a strong desire for vengeance, she seeks to punish the human traffickers who have mistreated her people. Her true name is Nayuta, a powerful secret she only shares with those she trusts completely, as knowledge of it by an outsider would grant them control over her mind.
