Frenci Mastibolt

Born as the daughter of the Southern Night Demon clan's chief, Frenci was once engaged to the protagonist Sairo before his sentencing. Even though the engagement has since been rendered legally void, she refuses to accept its dissolution and continues to follow him without hesitation. Her usual demeanor is one of an unreadable, mask-like blankness paired with a cutting tongue, yet beneath that frigid exterior lies an unwavering, single-minded devotion to Sairo—one she expresses through her own quiet, behind-the-scenes support.
