Background / History

Durandal and Bai Yan grew up together in the same orphanage. They spent nights discussing tactics, combat comprehension, and their shared ambition to become warriors fighting the Collapse. Durandal once imagined that they would remain together and fight until humanity’s victory, but Bai Yan eventually left her behind. Their reunion after graduating from the orphanage is strained by that separation. 7

During Bai Yan’s undercover mission in a feminine disguise, Durandal senses an unexplained familiarity with the disguised “Bai Yan” but cannot identify him. Her suspicion grows after encountering Bai Yan’s alleged “sister,” and she eventually questions Otto directly about Bai Yan’s mission and identity. 4 7 16

Durandal’s identity as Bianca Kaslana is publicly revealed during the conflict with Sakura. 190

Appearance

Durandal is a tall Valkyrie with long, curly golden hair. Her appearance is frequently associated with an imposing knightly presence, though she can be visibly flustered by public affection or Bai Yan’s provocations. 4 24

• Long, golden curls described as resembling mythic golden fleece. 4
• Wears blue-and-white armor in standard combat. 79
• Uses dark armor while in Guardian form. 190
• Carries the Divine Key Black Abyss White Flower as her primary lance. 40
• Has also appeared in an ice-blue long dress during Bai Yan’s disguise operation. 4

Personality

Durandal is driven by an intense desire to become stronger. As a child, she actively sought sparring partners, and she continues to pursue difficult opponents and training even after becoming Schicksal’s strongest S-rank Valkyrie. She does not become discouraged by overwhelming enemies; difficult fights instead heighten her fighting spirit. 21 40 190

She is direct, formal, and highly protective of those around her. Durandal questions Otto when she believes Bai Yan has been placed in unnecessary danger, disobeys orders to assist Bai Yan against Sirin, and reacts immediately when Rita is threatened. 16 63 108

Despite her confidence in battle, Durandal is vulnerable to social embarrassment. Bai Yan’s campaign of heart gestures from Valkyries leaves her blushing and unable to maintain her usual composure. 24
