Turi, eldest daughter of Gunther and Effa, was born in Ehrenfest one year before her sister Myne. She possesses naturally wavy blue-green hair and blue eyes, mirroring her mother. As her parents' first surviving child following infant losses, her survival held special significance.

Demonstrating maturity early on, Turi shouldered responsibility for her sickly younger sister Myne while their parents worked. Caring for the original Myne proved difficult, as the child resented Turi's health and frequently threw tantrums, strengthening Turi's protective nature and sense of duty. Her practical demeanor led neighbors to entrust her with supervising younger children during forest foraging.

Following Myne's transformation, where Urano Motosu inhabited Myne's body, Turi gained greater independence. She initially wrestled with jealousy when the new Myne displayed unexpected skills like basket weaving but remained steadfastly devoted. Turi often voiced deep concern for Myne's health, especially during severe fevers. She also admired the skilled seamstress Corinna, aspiring to apprentice under her.

At her baptism at age seven, Turi wore her hair loose during the formal ceremony registering her as an Ehrenfest citizen. Through her mother's referral, she secured a seamstress apprenticeship, aligning with her ambitions. Her developing craftsmanship eventually earned her a position with the Gilberta Company, specializing in hair ornaments. Recognition from wealthy merchants and nobles, including Prince Anastasius, prompted Turi to adopt more elegant manners.

Turi's bond with Myne evolved significantly. She served as Myne's emotional anchor, offering comfort during hardships and celebrating successes. When their brother Kamil grew older and questioned Myne's circumstances, Turi insisted on keeping Myne's origins secret for protection. Despite their closeness, Turi felt a growing distance due to diverging social spheres; her work in high society contrasted sharply with her lower city roots. This duality mirrored Lutz's experiences and underscored her internal conflict between ambition and belonging.

Turi embraced household innovations, adopting Myne's hygiene practices like frequent hair washing with homemade shampoo. Her early literacy skills, learned alongside Lutz, featured initially poor handwriting that presumably improved later.
