A talented engineer, Nina is extremely protective of her creations (which she expresses by constantly checking data of RX-78GP01 Gundam "Zephyranthes"). Her devotion to the Gundam Development Project is up to the level of obsession, and often leads her into conflict with her colleagues or Earth Federation officers, most notably Kou Uraki.

Her relationship with Kou was rocky at first, as Nina was annoyed by his childishness. However, they gradually became closer during the their time together, and she began to develop feeling for the young pilot. Despite this, Nina still harbored something for her former lover, Anavel Gato.
