Bala, also known as Nima in original sources, leads the desert tribe Tattoon, practitioners of "pattern magic." Her background includes encountering an anthropologist—Hibio's mother—during the latter's research expedition. Upon seeing a family portrait of the anthropologist's son Hibio (dubbed Eric in English adaptations), Bala resolved to marry him. She negotiated this arrangement directly with Hibio's mother, bypassing Hibio entirely.

Bala then traveled to Tokyo, appearing unexpectedly before Hibio to announce their impending marriage. Her arrival and persistent presence caused disruption as her tribal magical heritage clashed with Hibio's modern urban environment. Despite his initial reluctance and attempts to evade the arrangement, Bala greeted him with unwavering cheerfulness and determination.

She possesses a magical heritage linked to her tribe's practices, though specific abilities remain undefined beyond the cultural reference to pattern magic. Her physical appearance is described as beautiful within tribal aesthetics.
