Telmina resides in Crimonia as the mother of Fina and Shuri. Once an adventurer partnered with her first husband Roy and Gentz, her life changed drastically after Roy perished fighting monsters. Telmina fell gravely ill, becoming bedridden; her condition worsened over years until she neared death. Yuna intervened with healing magic, succeeding only after persistent effort following initial failures.

Cured and revitalized, Telmina actively reengaged in family life. She later married Gentz, Roy's former comrade and an adventurers' guild receptionist, relocating with her daughters. Shaped by years of hardship, Telmina exhibits a caring, motherly personality marked by frugality and a strong aversion to waste. She holds profound gratitude towards Yuna for saving her life and transforming her family's fortunes.

Telmina manages multiple enterprises for Yuna, serving as a representative for an orphanage and acting as an intermediary for the Commerce Guild. She initially clashed with Gentz over parenting methods, particularly concerning Shuri's safety during a flower-gathering trip, but they reconciled upon recognizing their shared commitment to honoring Roy's legacy.

Her relationships include guiding Fina and Shuri with warmth and stability, maintaining her enduring bond with Gentz, and viewing Yuna as both benefactor and employer. Telmina's own adventuring past informs her perspective on her daughters' occasional involvement with Yuna's activities, though she consistently prioritizes their safety. Her journey reflects a transition from vulnerability to becoming a proactive, emotionally resilient figure central to her family and community.
