Movie
Description
Lucrezia Noin, known primarily as Noin, hailed from privilege as the daughter of the President of the Noinheim Konzern and younger sister to Dix-Neuf Noinheim, the first President of the Mars Federation. Early evidence suggests a possible birth in space, contradicting common belief, leading her to run away to Earth following conflicts with her father.

Her military path started young when Treize Khushrenada selected her at age ten in AC 186 for the Specials' first mission suppressing a Mogadishu revolt. The mission achieved success with zero casualties, yet Noin was discovered weeping afterward, voicing a profound hatred for war despite her effectiveness. During this time, she developed a strong affinity for space and the stars and formed an early bond with Zechs Merquise, whom she nicknamed "Le Petit Prince." By AC 189, she undertook another mission under Treize on X-18999, where she requested the gender-neutral call sign "Noin" for combat.

Trained personally by Treize, Noin graduated from OZ's Lake Victoria Academy with the second-highest marks in its history, a position she reportedly accepted so Zechs could rank first. She served as a base commander and instructor for Specials recruits there. Despite her military skill, she consistently expressed disdain for warfare, stating her motivation stemmed solely from a love for outer space.

A pivotal moment occurred when her graduates died in an attack by Gundam pilot Chang Wufei. Consumed by rage, Noin pursued Wufei in an Aries mobile suit but hesitated upon realizing he was a boy, resulting in her defeat and emotional scarring. This event drove her to join Zechs, initiating their near-constant partnership. She later assisted Zechs in rebuilding the Wing Gundam and protecting his sister, Relena Peacecraft, eventually leaving OZ to become Relena's personal bodyguard and head of security for the pacifist Sanc Kingdom. In this role, she fortified the kingdom's defenses using white Taurus mobile suits and retrieved the Wing Gundam with rebel officer Sally Po.

When Zechs resurfaced leading the militant White Fang faction, Noin confronted him during his assault on the Peacemillion ship. She aimed her weapon at him but could not fire, dropping her cannon at the last moment; Zechs swerved to avoid harming her. Despite this perceived betrayal, she later stood by his side during his final battle against Heero Yuy, relaying the conflict's footage to Lady Une to galvanize public sentiment against war.

Post-war, Noin joined the Preventers peacekeeping organization under the codename "Fire." She partnered with Sally Po ("Water") to counter new threats, including the Mariemaia Army uprising. During this conflict, she reunited with Zechs (using the codename "Wind"), and together they attempted to rescue the kidnapped Relena. Following the Mariemaia Army's defeat, Noin and Zechs departed for Mars to support Relena's terraforming initiatives.

Physically, Noin stood 165 cm tall, weighed 47 kg, and possessed dark purple eyes and platinum-black hair. Her personality blended fierce loyalty, idealism, and maternal protectiveness. She maintained unshakeable faith in Zechs despite their ideological clashes and exhibited a habit of counting the days since their last meetings. Her skills encompassed piloting mobile suits like the Aries and Taurus, though her tactical approach consistently prioritized minimizing casualties and resolving conflicts through non-violent means whenever possible.
