Nene Romanova is an 18-year-old member of the Knight Sabers, acting as a technical conductor and hacker, and is an employee of the AD Police, functioning as the Knight Saber's mole in the ADP world. She is bubbly, naive, has an affinity for candy and junk food, and is blissfully inept with real world logic. Due to her lack of (and unwillingness to engage in) regular exercise, she is often teased by Priss and Linna for not being more physically durable.

Nene's purple and pink Hard Suit's offensive weapon is a weak laser gun unsuited for taking out enemies; instead, it is used to scribble the Knight Sabers' signature onto their scene of actions. She relies on her suit's computer and electronic warfare systems to stay away from an enemy. In episode 8 of Crisis, Nene receives an upgraded pink-colored suit, which is also used in Crash. Her suit's offensive capabilities are stocked up considerably with an electromagnetic pulse striker and the capability of physically hacking into a Boomer's computer brain.
