Nunnally vi Britannia

Nunnally vi Britannia (ナナリー・ヴィ・ブリタニア, Nanarī vui Buritania), 14 years old (15 at R2), is one of the main characters of Code Geass. She is the Fourth Princess of the Holy Britannian Empire and the Eleventh Prince Lelouch vi Britannia's blind and crippled younger sister. After she was exiled she used the alias, Nunnally Lamperouge (ナナリー・ランペルージ, Nanarī Ranperūji). Her seiyū is Kaori Nazuka. In the English dub, she is voiced by Rebecca Forstadt. While her role is limited in the anime series, a spin-off manga entitled Nightmare of Nunnally focuses on her, depicting what would have happened if Nunnally had received Geass as well as Lelouch - though it notably changes the idea, limits and abilities of Geass.

Personality
Throughout the series Nunnally has shown to be almost inhumanly kindhearted, patient and understanding. She endured her double handicap of blindness and paralysis with a smile and warmth (though Lelouch stated that she would throw terrible temper tantrums in private when she was little) and she is kind and empathetic to all those around her. Nunnally has gentle ideals and due to her telling Euphie to not expose her and her brother's royalty as well as her belief that what Zero is doing is wrong, she is on a neutral side meaning she will make the world a better place in her way.

However, like Lelouch, Nunnally has shown that she can make heavy-hearted decisions bordering on ruthlessness, as shown when she willingly fires multiple F.L.E.I.J.A in order to make it a symbol of hatred for the entire world. Despite this, Nunnally's greatest weakness is her kind heart, unable to be as cold and calculating as her brother.

Also, in the official novel, Nunnally has a much darker side which rivals Lelouch. It is revealed that the kindhearted personality was only a facade to hide her darkside ( She deeply resents the fact that she is helpless and has to rely on other people all the time) and because she loves her brother and wants to be the sweet girl he likes. When Lelouch abandoned her in order to conquer the world, the mask she wore broke and  she finally showed her true personality. During the final battle, she sneered at Suzaku for being a wimp, wallowing just because he killed his father and told him that such act is a common event in the Britannian royal family, she also gloated him how he is never able to protect anyone he swore loyalty towards and she is lucky to find that fact in time and take back the request for asking him to be her knight.

Character Outline
Nunnally was a Princess and a daughter of Emperor Charles zi Britannia, and imperial consort Marianne vi Britannia. She was 87th in line of succession to the Britannian throne. When her mother was assassinated, Nunnally was paralyzed by bullet wounds on her legs, and went blind due to the geass of her father making her believe that she is blind. Lelouch believes that she may be able to see again someday. After the confrontation between Lelouch and the Emperor of Britannia about the murder of their mother, both Lelouch and Nunnally were exiled to Japan as political prisoners. They then went on to live in Kururugi residence where she first met Suzaku Kururugi.

After Britannia invades Japan, Lelouch hides their identity and changes their surname to Lamperouge. They then seek help from Marianne's old allies, the Ashford family, who kept their identity a secret and allowed the two siblings to live in a building on campus to accommodate her disabilities. Nunnally attends Ashford Academy's middle school and is friends with Lelouch's classmates, particularly Shirley Fenette. She is very kindhearted and calls the Elevens "Japanese people". It is revealed in R2 that her birthday is October 25.

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. After Lelouch saved Suzaku, he returns back to Ashford Academy and is surprised to see Nunnally folding origami cranes with C.C.. Nunnally welcomes Lelouch back and tells him that C.C. has come to visit him.

Arthur, a stray cat, is later chased throughout the school grounds by the entire student body after wandering into the Lamperouge residence and escaping with Lelouch's Zero mask. Milly announced that the one who would catch the cat would get a kiss from any member of the Student Council. Suzaku and Lelouch were the ones that got the cat and got a kiss on the cheek from Nunnally. The Student Council adopts him and builds a cat house in the council room. Following this incident, Nunnally along with the rest of the student body watches Prince Clovis' funeral on live. During the funeral, the Emperor of Britannia, makes a speech on the virtues of inequality and the social battle for evolution and betterment.

Afterwards, she appears again being kidnapped by Mao who is using her to get to Lelouch for payback for what he did to him. After locating Nunnally, Lelouch and Suzaku are shocked to see a bomb located above her. However, with teamwork, Lelouch and Suzaku manage to rescue Nunnally.

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 well-coordinated Britannian forces, ending in their decisive defeat.

Second Season
The second season reveals that everyone's memories of Nunnally have been erased, Lelouch's included. Everyone at Ashford Academy believes that Clara Frank and later Rolo Lamperouge is Lelouch's younger sibling instead, and has been the entire time. It is unknown if Nunnally and Julius encountered each other between the two seasons. 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, though she is unaware of his identity as Zero. Nunnally suspects that something has happened between her brother and Suzaku. 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 Alicia 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 when his life was in danger.

When Lelouch converses with Charles and Marianne in The Ragnarök Connection (episode), it is revealed that Nunnally's injuries were orchestrated by V.V., who set her up to be a witness to the murder of her mother. Her blindness, which was thought to be psychological, was actually the result of Charles' Geass, done to protect her against possible reprisal by V.V. Charles then chose to send them both away, arguing that he was doing so to protect them from V.V., whom he felt he could no longer trust.

During the Battle of Mt.Fuji, Lelouch manages to make his way onto the Damocles and confronts her, but is shocked that Nunnally was able to break through Charles' Geass when she opened her eyes to greet him, asking if he will use Geass on her. Nunnally refuses to give Lelouch the Damocles Key, and she explains that Damocles will become a symbol of hatred among the people, allowing them to move forward into the future once it's gone.

As this is the same plan Lelouch has devised, only with himself as the symbol, he uses his Geass to force Nunnally to relinquish the key and uses Damocles to take over the world. Calling him a coward and a liar, Nunnally can only watch helplessly as Lelouch walks down the stairs, preventing her from chasing after him.

Two months later, Nunnally is a prisoner bound in chains and forced to wear a rather revealing red dress, being taken to witness the execution of the U.F.N. leaders. When Suzaku, in the guise of Zero, appears and impales Lelouch on his sword, Nunnally can only watch in shock. When Lelouch falls near her, she takes his hand and realizes that he has sacrificed himself on purpose. Declaring her love for her brother, Nunnally cries hysterically as Lelouch dies. Some time later Nunnally becomes the Empress of Britannia and remains an important diplomatic figure with Zero (Suzaku) and an obedient Schneizel, who was geassed by Lelouch before his death, to serve "Zero", by her side.

Lelouch vi Britannia
Lelouch is the closest person in Nunnally's life. He was her brother, confidant, and caretaker all through their exile. It was because of Nunnally that Lelouch began his quest as Zero, but all Nunnally really wanted was for her brother to always be by her side. It is unknown if Nunnally interacted with Julius Kingsley. After finding out that her brother was Zero all along, she still loved him regardless and understood since she has faith due to her love as hinted by Charles Zi Britannia during his conversation with V.V. After Lelouch began his quest on Zero Requiem, she start to feel sad and negativity on why he was doing all of this since Lelouch could not bring himself to explain his actions, all her negative feelings disappear and are instead replaced by anguish when she realizes why he had himself killed and that his intentions are indeed noble after all this time. She loves Lelouch above all others and her only wish was to be with him.

Suzaku Kururugi
Suzaku is one of Nunnally's closest friends, having known and played together since childhood, and comforting him during the hard times of the sakuradite conflict. Lelouch orginally intended Suzaku to become Nunnally's guardian due to his increased activities with the Black Knights only to be swayed by Euphie which creates a more and tragic conflict. When she becomes the Viceroy of Area 11 they become close to each other again. Nunnally later asks Suzaku whoever called her on the phone and after Suzaku stepped away from her, she realizes that he is the same as Lelouch. After Lelouch and Suzaku declare the world as enemies, her attitude towards Suzaku becomes the same as Lelouch after being denied the truth of Lelouch's actions. After Lelouch is assassinated by Suzaku, as Zero, he becomes Nunnally's personal protector. Nunnally views Suzaku as a close friend and to a less extent, a substitute of Lelouch but Nunnally will always treasure Lelouch no matter what.

Alice
Alice is Nunnally's best friend, from Nightmare of Nunnally. Nunnally first encountered Alice when she defended her and beat up 3 bullies while on her way to class. They next properly met on top of a roof during a festival at Ashford, Nunnally had already recognized Alice as the new transfer student in her class who had also defended her that time. Since then, Nunnally and Alice have been very close and Alice has always come to Nunnally's aid when she's in trouble. Despite their friendship, Alice feels somewhat guilty due to the fact that she's really a Britannian soldier on an observation mission to Ashford, a fact she hides from Nunnally. While hacking into the Ashford computer database one night, Alice discovers Nunnally and Lelouch's real identities and that the Ashfords have been hiding them from the Empire. While it's her duty to report this to her superiors, Alice deletes the files instead and stays silent about it due to the fact that Nunnally is her best and only friend.

After saving Nunnally from Mao who had kidnapped her, Alice decides that Nunnally is no longer safe and makes it her goal to become a Britannian Knight in order to protect her. Alice is shocked to find that pilot of Mark Nemo is none other than Nunnally. After she is captured and imprisoned, Alice confronts her and Nunnally realizes that Alice is a Britannian soldier and asks if she's just been lying to her the entire time while pretending to be her friend and though Alice tries to explain, Nunnally rejects her. When Alice finds out Nunnally is to be executed, she tries to kill Rolo Vi Britannia but is imprisoned herself. She then makes a contract with Nemo and assists Zero, Suzaku and Euphemia in rescuing  Nunnally.

After taking Nunnally to the Sword of Akasha and confronting her parents, Alice plays a vital role in stopping their plan to initiate the Ragnarök Connection by confessing to Nunnally that she loves her, thus confirming Nunnally's beliefs about hope and happiness in the world and also enabling her regain the use of her legs along with her sight. Later on when Nunnally becomes a goodwill ambassador, she and Alice talk over all that has happened and Nunnally asks Alice to become her official knight and be by her side into the future which Alice happily and tearfully accepts.

Kallen Kozuki
Nunnally first met Kallen when she was introduced to the Student Council. Kallen found her sweet and was very doting to her. Prior to the second season, Kallen was told by C.C. about Lelouch and Nunnally's royalty. It was presumed that they had a good friendship as when Kallen was captured by the Britannian army, Nunnally attempted to make her feel more comfortable by giving her a better cell and clothes. They bond through their experiences with their older brothers.

C.C.
Nunnally's only interactions with C.C. were early on in the series. C.C met Nunnally shortly after the Orange Incident and spent time with her making origami cranes. Nunnally was curious about Lelouch's relationship with C.C and momentarily thought that they may be in a relationship but Lelouch played that off as a joke. In the picture drama, Nunnally later brings up C.C with Lelouch and he once again denies their relationship as a joke. When V.V kidnaps Nunnally, his presence made her think that it was C.C.

Charles zi Britannia
Nunnally, like Lelouch, hates their father since he abandoned both him and Nunnally and not telling the truth of their mother's death. Even though he reinstated Nunnally back into royalty, she continues to hate him no matter what due to her gentle ideals and her opposition against Britannia's system. However, she never openly shows this when in his presence. When questioned by V.V. why Charles didn't reveal Nunnally her brother's identity as Zero and his Geass, Charles deeply understood the relationship between Lelouch and Nunnally as unbroken siblings.

Kaguya Sumeragi
In the past, Nunnally met Kaguya but their relationship was rather unknown. Kaguya witnesses Nunnally's appearances as the princess of Britannia before and was unaware that she aided Zero whose identity was Lelouch. After Zero Requiem, Kaguya couldn't help but feel remorse for Nunnally's mourn of Lelouch's passing. They were later seen again at a UFN conference meeting at Miraculous Birthday. In the manga, she greets Nunnally's hand at a peace negotiation.

Abilities
After the death of her mother, Nunnally is left unable to walk, and later her father casts his Geass on her causing her to believe that she is blind. She has the natural ability to know if a person is lying by touching their hand.

Nunnally has shown to be not only perceptive, but also intelligent by coming up with a similar plan as Lelouch (using the Damocles as an object of hatred).

Code Geass: The Manga
Unlike the anime, in the 2nd part of the storyline, she arrives after the UFN formation and does not reestablish the Special Administrative Zone possibly due to the war between UFN and Britannia.

Nightmare of Nunnally
Nightmare of Nunnally features an alternate story to the Code Geass series with Nunnally as the protagonist. It is not connected with the television series.

After the so-called "gas release" incident in the Shinjuku Ghetto, Nunnally arrives in the ruins seeking the missing Lelouch. A disembodied doll-like energy life-form, Magical Device Nemo (魔導器ネモ madouki nemo), appears before her and offers her a Geass contract. Nunnally accepts and gains the ability to see "lines of the future" (similar to the Geass of Bismarck Waldstein, though more accurate than his). Nemo assumes an appearance resembling an albino Nunnally upon contract finalization, and the two of them come to share a single mind. Nemo's personality remains distinct from Nunnally, and is said to be an expression of Nunnally's unconscious anger and hostility.

Nunnally and Nemo find themselves "as one" aboard the mysteriously manifested Knightmare Frame Mark Nemo. Angered that Lelouch might have been killed or injured, they quickly destroy several enemy Sutherlands. In retaliation, Clovis la Britannia sends Jeremiah Gottwald, Villetta Nu, and a unit of Sutherlands to intercept the Mark Nemo. Using their now shared Geass, Nunnally and Nemo defeat the entire unit. Their attention turns to Clovis, but they decide at the last moment to spare him upon recalling Lelouch's wish for a peaceful world.

Nunnally awakens in her normal body and her first response is to violently deny her participation in the conflict she has just witnessed. Nemo suddenly appears before her, claiming to be "an alternate manifestation of the girl known as Nunnally", the manifestation of the darkness in Nunnally's heart. She states that as per their contract, she will now become Nunnally's knight and protector. Nunnally is the only one that can "see" Nemo.

Nunnally's Geass contract gives her and Nemo the shared ability to read "the lines of the future", a skill functionally identical to precognition. A red, bird-like sigil lights up in Nemo's left eye when the ability is activated. When combined with their Knightmare Frame, the Mark Nemo, Nunnally and Nemo are unstoppable on the battlefield, since every move is known to them beforehand. In the anime, this type of Geass is used by Bismarck, the Knight of One; however, his is slightly different, in that it only reads a specific person's "line", rather than that of the future in general.

However, there is a side effect to using the geass as shown when Nunnally is forced to be confined in a bed due to extensive use of her powers.

At the end of Nightmare of Nunnally, Nunnally also regains the ability to walk and becomes the Goodwill Ambassador to Japan. She also makes Alice her knight.

Lost Colors
In the video game spin-off for the PlayStation 2 and PlayStation Portable, the player can make Rai fall for Nunnally. Lelouch will be reluctant to accept their relationship, and if Nunnally is the chosen girl in the Blue Moon route, he will be with them during their first date.

In the Geass route ending, Nunnally met with Rai in her room while making origami, revealing to him that she had made a sakura flower. While Rai didn't say anything Nunnally however noticed something was wrong, which led her to tremble as she fears that he will disappear. Rai however confirmed it, but also lied her that he will return, calming Nunnally down. Nunnally later told Rai that she will continue making origami until he returns, which pleases him but was secretly saddened as he gives her his last lesson. After Rai sealed himself in the Thought Elevator, a scene shows Nunnally with Sayoko seeing bright lights falling from the sky. Later Nunnally was greeted by Sayoko, who was surprised as she witnesses Nunnally's room being filled with origami. When Nunnally picked up an earlier flower shaped origami with folded creases, she unknowingly started to cry and didn't know why.
