First season Nunnally's role in the first season is rather minor, serving as little more than motivation for Lelouch's goal of overthrowing the Britannian empire and creating a world where Nunnally can live in peace. She is kidnapped by V.V. near the end of the season, and Lelouch abandons the
Black Knights in the middle of battle to save her. Not only is he unsuccessful in doing so, being captured by Suzaku en route, but his departure leaves his forces powerless against the better trained Britannian forces, ending in their decisive defeat.
Second season (R2) The second season reveals that everyone's memories of Nunnally have been erased, Lelouch's included. Everyone at Ashford Academy believes that Rolo Lamperouge is Lelouch's younger brother instead and has been the entire time. After Nunnally was taken, Rolo took over as Lelouch's younger brother. After recovering his memory, Lelouch deduces that Nunnally is likely being held hostage by the Emperor, who would not hesitate to use his children to achieve his goals. As a result, Lelouch must try to maintain the masquerade that he has not regained his memories in order to protect her. Nunnally makes her first appearance in the second season as a Britannian princess and the new
Viceroy of Area 11. She still remembers Lelouch as her older brother, though she is unaware of his identity as Zero. Nunnally has vowed to continue her late older half-sister
Princess Euphemia's will by reinstating the Special Administrative Region in Japan, sharing her and Suzaku's belief that the world can be changed in gentle ways. After
Kallen Stadtfeld is captured and sent back to Area 11, Nunnally has her transferred to a better facility and gives her a dress to wear in lieu of an ordinary prisoner jumpsuit. They strike up a conversation about Lelouch, which Suzaku interrupts. He asks to speak with Kallen alone, specifically using her prisoner number rather than her name, which Nunnally notices. She also suspects that he is lying about Lelouch to protect her. During a meeting discussing the redevelopment of the ghettos, she confronts
Miss Lohmeyer on the burdens it places on the Eleven population, able to tell from holding her hand that she is downplaying the problems it will cause. She insists that it be rewritten until it does not do so. During the second battle of Tokyo, Rolo and Sayoko are sent to retrieve Nunnally. Though Sayoko manages to commandeer the transport set to evacuate Nunnally, both are seemingly killed when they are caught in the blast radius of Nina's
F.L.E.I.J.A. bomb, fired unwillingly by Suzaku (compelled by Lelouch's Geass command "to live") when his life was in danger. When Lelouch converses with Charles and Marianne in episode 21, it is revealed that Nunnally's injuries were orchestrated by V.V., who set her up to be a false witness to the murder of her mother. Her blindness, which was thought to be a result of the traumatic assassination of her own mother, was actually induced by Charles' Geass, in order to protect her against possible reprisal by V.V before sending both her and Lelouch away to Japan. However, since Charles went ahead with his war and did not care about their subsequent fate, Lelouch concluded that they were less important than his grand plan: the Ragnarök Connection. Lelouch spurns his parents, asking them why Nunnally always smiled. When they do not get the question, he answers that her smile was in gratitude since her blindness placed her at the mercy of others. At the end of episode 22, Nunnally is revealed to be alive, having taken a different ship that evaded the
F.L.E.I.J.A. She is now on board Schneizel's floating fortress, the
Damocles. She declares herself to be an enemy of Lelouch and Suzaku, being supported by Schneizel as the rightful heir to the throne. However, Schneizel is actually manipulating her to ensure that she remains an enemy of Lelouch and wishes to seize the throne only for himself. Nunnally insists on being given the
F.L.E.I.J.A. launch button, wanting to personally atone for her brother's sins. She is disturbed by how easy it is to launch warheads at Lelouch, destroying a large portion of his fleet and causing many deaths. When Lelouch's counterattack succeeds in reaching the
Damocles, Nunnally drops the launch key and is thrown off of her wheelchair. While she is on the ground trying to find the key, she manages to break Charles' Geass with her own willpower and returns to her wheelchair before Lelouch arrives. When Lelouch confirms that he has come for the key, she opens her eyes and asks her brother if he will now use his Geass on her. Though hesitant to use his Geass on her, Lelouch uses it after Nunnally explains she intends to turn the
Damocles into a symbol of hatred to unite everyone in the world—a near-duplicate of his own plan to use himself as the symbol. Lelouch forces her to relinquish the key so he can use the
Damocles to take over the world, telling her that he does and will always love her in the process. After realizing what occurred, unaware of the kind words Lelouch said to her while under her trance, Nunnally calls Lelouch a demon as she helplessly watches him leave. Two months later, Nunnally is a prisoner being taken to witness the execution of the U.F.N. and Black Knight leaders. When Suzaku, masquerading as Zero, appears and kills Lelouch, Nunnally can only watch helplessly in horror as her brother is impaled. When Lelouch falls near her, she takes his hand, and immediately understands Lelouch and Suzaku's plan, realizing the truth as her brother dies. Nunnally cries hysterically while holding her brother's lifeless body as the crowd cheers Zero. Following Lelouch's death, Nunnally ascends the throne as the Empress of Britannia, with Suzaku (as Zero) and a Geass-compelled Schneizel by her side. ==Appearances in other media==
