Code Geass

Lelouch and Suzaku fight for the sake of their promise, the Zero Requiem. Suzaku battles Kallen, while Lelouch confronts Nunnally, his biggest and dearest enemy.

Schneizel unveils his plan to position the Damocles in such a way as to strike every warring nation in the world, thus enforcing peace through the threat of annihilation. Cornelia objects, but is gunned down. Lelouch declares Nunnally his enemy during their conversation, but in private has trouble with the thought of fighting her. With some harsh words from Suzaku and C.C.'s comfort, Lelouch comes to his senses and focuses on his original task. Nunnally, frustrated that she cannot fight or protect anyone, decides to shoulder the sin of launching F.L.E.I.J.A. herself. Schneizel, backed by the Black Knights and the remaining Knights of Rounds, clashes with Lelouch in the sky above Mount Fuji. Though Lelouch is able to destroy a fair portion of the Black Knights by detonating the sakuradite mines in Mount Fuji, the Damocles remains unassailable and its payload of F.L.E.I.J.A. warheads still looms over him.

Within the Sword of Akasha, Lelouch learns the truth about his mother's death from the Emperor and Marianne herself. The two reveal their intention to create a gentle world without lies, and begin Ragnarok. Lelouch almost reconciles with them, but changes his mind when he realizes that the world the Emperor desires has no future. Evolving his Geass to its next level, Lelouch defeats the Emperor with the help of the collective unconscious mind of every human, the personification of the "gods" the Emperor sought to defeat, dissolving both him and Marianne into dust. With Ragnarok ended, Lelouch takes up the throne as the new Emperor, using his Geass to make all the dissenters in the court acknowledge him as such. Suzaku is appointed as his new "Knight of Zero," while C.C. looks on from the shadows.

A ceasefire is called so Schneizel can meet with the leaders of the Black Knights, but Lelouch is too devastated to attend. Schenizel reveals the truth about Lelouch and his Geass, as well as the many people he has used it on; a recording from Lelouch's meeting with Suzaku solidifies the evidence. In exchange for Japan's independence, the Black Knights agree to betray Lelouch. Unable to escape, Lelouch tells Kallen he was using her all along to keep her from sharing his fate, but whispers that she should live on within earshot. Lelouch is prepared to accept death, until Rolo, piloting the Shinkirō, rescues Lelouch and escapes the combined forces of the Black Knights and the Britannians. However, the excessive use of his Geass required to do so overtaxes his heart and dies after flying Lelouch to safety. Lelouch resolves to not waste the life given to him by Rolo, declaring he will kill the Emperor by his own hand.

The battle for Japan gets underway, and it does not start out well for the Black Knights. Luciano and Bismark decimate their ranks, with only Li Xingke to keep them at bay. Suzaku and Lelouch meet to discuss Nunnally. After some initial animosity, Lelouch manages to win Suzaku over. However, Schneizel has his personal guard arrest Lelouch, making Lelouch believe Suzaku has betrayed him. Schneizel and Lelouch have a private chat, and Lelouch is rescued by none other than Guilford, having used his Geass on Guilford beforehand to make him believe he is Cornelia. Using the Gefjun Disturber train network, Lelouch shuts down the Tokyo Settlement. At the same time, his reinforcements emerge from the ocean, ready to take advantage of the opportunity. Meanwhile, the Emperor is preparing for Ragnarök.

Suzaku realizes he cannot stoop to Lelouch's level to achieve his goals and decides not to use Refrain on Kallen. Instead, he heads to Ashford, where he discovers the Intelligence Agency is under Lelouch's control. Ohgi and Villetta meet in the woods, where Villetta intends to kill him, but Ohgi confesses that he has fallen in love with her. Sayoko interrupts and attempts to dispatch Villetta, and Ohgi is injured in the struggle. He tumbles off a cliff and Villetta jumps after him. Nina and the In Vogue staff make their first successful nuclear bomb test. Lelouch confronts the Emperor atop the Sword of Akasha. He learns the Emperor has taken V.V.'s "Code," which has made him immortal. C.C. appears and reveals to Lelouch her wish is to die, then transports him to "C's World" to ensure his safety, where he witnesses her past. Upon realizing her true wish, Lelouch returns to reality, proclaiming he shall be the only one to grant her wish. He attacks the Sword of Akasha with the Shinkirō and rescues C.C., only to find she has lost all her memories except those before receiving the power of Geass.

Having recovered her memories, Shirley questions her perception of reality. Lelouch heads to the train station to check on the delivery of a G Train, a network of Gefjun Disturber-equipped trains that will black out all of Tokyo once active. Meanwhile, Jeremiah makes his move on Ashford Academy, overwhelming Sayoko and Rolo in his search for Lelouch. Villetta willingly reveals Lelouch's location and Jeremiah corners him, but is paralyzed by the G Train. Struggling, Jeremiah asks why Lelouch betrayed the Emperor, to which the former prince reveals his motivation to avenge his mother. Having greatly admired Marianne, Jeremiah joins Lelouch's cause. Shirley finally reconciles her restored memories, asking Suzaku to forgive Lelouch as she has. Before she can reach Lelouch, she runs into Rolo, who uses his Geass once she reveals knowledge of Nunnally. As Lelouch leaves, he discovers Shirley mortally wounded, who confesses her feelings for him as he desperately commands her to live.

Back at Ashford Academy, Sayoko Shinozaki is posing as Lelouch. Realizing the Eunuchs are not interested in saving Tianzi, Li Xingke rebels. As the Black Knights hold their ground against the Chinese Federation and Britannian forces, Zero tries to reason with the Eunuchs, who openly admit their treachery. When Xingke tries to shield Tianzi from the fighting, Zero personally enters into the field with his new Shinkirō Knightmare Frame. Diethard hacks into the Chinese media network and replays the Eunuchs' deceit, igniting riots across China. Faced with open rebellion, Schneizel orders a Britannian retreat and Xingke eliminates the Eunuchs and rescues his comrades. However, Kallen and the Guren have been handed over to Britannia. With the Eunuchs dead, Zero forges an alliance with Xingke and Tianzi. Lelouch returns to Ashford Academy, and is surprised to find Anya and Gino enrolled as students.

The wedding is orchestrated by the High Eunuchs, who will become nobility in Britannia in exchange for turning over half their land to Second Prince Schneizel el Britannia. As the wedding begins, Li Xingke initiates a coup-d'état to overthrow the Eunuchs, but before he can free the Empress, Lelouch appears and takes her hostage. Elsewhere, V.V. prepares to unleash Jeremiah Gottwald against Lelouch and C.C.

Nunnally is sworn in as the new Viceroy of Area 11, and reveals her intention to restore the Specially Administrated Zone of Japan. Knowing he cannot go against his sister's wishes, Lelouch slips into a state of depression. Before he relinquishes himself to Refrain, Kallen steps in, reminding him his duty as Zero to realize the dream he gave to the Japanese. An evesdropping Rolo emerges, attempting to persuade Lelouch to abandon his identity as Zero and return to being a high school student. Meanwhile, the Black Knights are under attack by a Britannian naval fleet, led by Suzaku. A glimmer of hope is revealed to Lelouch after he sees fireworks setting off at Ashford Academy. Rushing to the battlefield, he successfully leads the Black Knights to defeat the entire naval fleet and surprise Suzaku by appearing as Zero, announcing his intention to accept Nunnally's offer to join the Specially Administrated Zone of Japan.

Suzaku returns to Ashford Academy to investigate Lelouch. With the Black Knights reassembled, Lelouch plans to lead the resistance while maintaining his façade as a student. A welcoming party is held for Suzaku at the academy, and C.C.'s love of pizza threatens to reveal Lelouch's secret; Kallen arrives to retrieve her but is seen by Villeta. She tells Lelouch how she came with Kaname Ohgi the previous year, and Lelouch uses this information to blackmail her. Alone, Suzaku reveals to Lelouch his goal of becoming the Knight of One, which would allow him complete governing authority over Area 11. To test Lelouch, he allows him to speak with the new Viceroy of Area 11: Nunnally vi Britannia.

Lelouch returns to the Ashford Academy during the broadcast, causing Villeta Nu's Special Division to have doubts he was the Zero on television. Needing information on his sister's whereabouts, Lelouch sets a trap to turn Rolo into his pawn. Gilbert G.P. Guilford, Cornelia li Britannia's knight and acting Viceroy of Area 11, presents an ultimatum to Zero: reveal himself or let the incarcerated Black Knights face execution. Elsewhere, Suzaku leads the Britannian frontlines in the Lancelot in the war against the Euro Universe. Lelouch confronts Rolo, but Rolo's unique abilities allow him to gain the upper hand.
