Tirumina, sometimes called Telmina in certain records, resides in the city of Crimonia. She is the mother of Fina and Shuri and the widow of Roy, a former adventurer who perished battling monsters. Following Roy's death, Tirumina fell ill and became confined to her sickbed; her condition steadily declined over the years, bringing her near death. This illness plunged the family into poverty, forcing her young daughter Fina to shoulder heavy responsibilities to sustain the household.

Her recovery came when Yuna, a powerful adventurer, employed healing magic to restore her health. After this, Tirumina married Gentz, an Adventurers' Guild employee and a former companion from her own adventuring past. The family relocated together to a new home.

Once recovered, Tirumina took on the role of manager for Yuna's diverse business enterprises and also serves as an intermediary for the Commerce Guild. She is a caring and motherly individual. Having endured prolonged hardship, she avoids waste and feels profound gratitude toward Yuna for saving her life and supporting her family. She remains deeply devoted to her children.

Initially frail and pale, she transformed after her healing into a bright and active woman. She possesses light skin, lime-green eyes, and greenish-brown hair longer than her daughters’, loosely tied to one side. She often wears a gray cardigan over a green and white striped ankle-length dress.
