Cait-Sith, Azalie

アザリー・ケットシー

She serves as Orphen's foster sister, best friend, and the entity known as Bloody August. Having grown up in the same orphanage, they arrived at the Tower of Fangs together, both regarded as magical prodigies. She provided him with extensive tutoring and special attention. She was a formidable sorcerer—perhaps one of the greatest. Yet, she possessed two distinct sides: the kind, loving Azalie and the "scary" Azalie, as Orphen describes her. Following the rejection of her love confession to another person, she appeared nearly obsessed with her studies, craving greater power. One of her experiments transformed her into Bloody August, the name assigned to the dragon that first emerged in August.
