Toya was a Starfleet crewman assigned to the operations division of the starship USS Enterprise-D in 2364.

She was the mother of Alexandra who was briefly kidnapped by the Aldeans in an effort to re-populate their planet. Alexandra disappeared while playing in their quarters and Toya was sitting not far away from her. She later participated in a meeting in the observation lounge with the other parents whose children were kidnapped. (TNG: "When The Bough Breaks")
