Silky Mau is a Ferario fairy, native to Byston Well. In the original "Aura Battler Dunbine" series, Drake Luft captured and utilized her to open the Aura Road, a dimensional pathway. This action enabled Luft to summon aura warriors from Upper Earth (Earth) to pilot aura battlers for his military campaigns, making her role critical to his initial successes.

Centuries later in "The Tale of Neo Byston Well," Shion Zaba, a young hunter from Baran-Baran, initially captures Silky Mau. After Shion releases her, she chooses to aid him. She assists Shion and Princess Remul Jilfird in escaping Rabaan Zaramand (the Black Knight), who seeks to conquer Byston Well and targeted Baran-Baran for its legendary treasure. This treasure is revealed to be the powerful aura battler Sirbine, which Shion pilots with Silky Mau's direct support.

Silky Mau possesses notable intelligence and strategic acumen, frequently contributing to tactical decisions during conflicts. She self-identifies with assertiveness and complexity, stating, "I am Silky Mau. I am the most beautiful woman in Byston Well, and I'm also the cruelest." Despite this proclaimed cruelty, she demonstrates loyalty to her allies and reveals underlying vulnerabilities when affected by personal losses. Her abilities include directly supporting aura battler operations, providing piloting assistance, and leveraging her extensive knowledge of Byston Well's lore and technology. Her character bridges the original series and the OVA as a supernatural being tied to Byston Well's core mechanics.
