In 2355, Lupaza met young Kira Nerys, who wanted to join the resistance. Although the rest of the cell found Kira too young she felt that Kira had the heart of an sinoraptor and supported her. After Kira's first mission she made her a Bajoran earring out of the metal of a destroyed skimmer.
In 2373 she visited Kira on DS9 with Furel because someone was killing their former resistance comrades. While they sneaked aboard DS9 unnoticed by beaming into Chief O'Brien's bedroom their assailant knew where she was and planted an explosive device on the station's window by means of a hunter probe. When it exploded, the room decompressed and she was killed. (DS9: "The Darkness and the Light")
