Kallen Kozuki is a key fighter in Code Geass. She is half Britannian and half Japanese, but in her heart she sees herself as fully Japanese. At Ashford Academy, she uses her Britannian father's family name, Stadtfeld. She gets great grades and sits on the student council with Lelouch. To hide her secret, she acts weak, sickly, and polite at school.

Outside school, Kallen is a very different person: bold, fierce, and stubborn. She fights against the Britannian Empire, which has taken over Japan and renamed it Area 11. At first, her main reason was her older brother, Naoto, a resistance leader she loved. After he died, she carried on his fight. Her home life was also painful. Her Japanese birth mother works as a maid in the family house and is treated badly by Kallen's Britannian stepmother. For a long time, Kallen was cold to her mother too. When her mother fell into trouble, Kallen realized how much she loved her, and she began fighting for a world where they could live happily together.

Kallen joins the Black Knights, the rebel army led by the masked Zero, and becomes his fiercely loyal ace. She pilots the Guren, a powerful Knightmare Frame (a giant fighting robot), and she is one of the best pilots in the whole series. She does not know at first that Zero is Lelouch, whom she found annoying at school. Her feelings toward him, and toward C.C. and Suzaku, become more tangled in R2.

Code Geass: Lelouch of the Rebellion R2 is the second and final TV season of Code Geass, a mecha and political drama from Studio Sunrise. It aired in Japan from April to September 2008 and has 25 episodes. Goro Taniguchi directed it, and Ichiro Okouchi wrote the story. The famous art group CLAMP designed the characters. R2 won the Best Screenplay award at the 2009 Tokyo Anime Fair. The story is set in an alternate world. In this history, a huge empire called the Holy Britannian Empire rules much of the planet. Britannia conquered Japan and gave it a number instead of a name: Area 11. Japanese people there are called "Elevens" and are treated as second-class citizens. The empire fights with giant robot suits called Knightmare Frames, which pilots ride into battle. The main character is Lelouch Lamperouge. He looks like a normal high school student, but he is really an exiled prince of Britannia. In the first season, a strange, green-haired girl named C.C. gave him a power called Geass. With it, Lelouch can look someone in the eye and give them one order they must obey. He used this power to become Zero, a masked leader who fought the empire with a rebel army called the Black Knights. His goals were to get revenge for his mother's death and to build a safe world for his younger sister, Nunnally, who cannot walk or see. R2 picks up about a year after the first season ended with a failed uprising. The rebels are scattered, Zero is gone, and the empire is sending most of its armies to fight in Europe. At first, Lelouch seems to be living a quiet student life at Ashford Academy, with no sign that he was ever the masked rebel. That calm does not last long. Soon he is pulled back into the fight, and the struggle becomes larger than ever. Old allies, new rivals, and powerful groups from other nations all play a part. One of the most important people in the series is Suzaku Kururugi, Lelouch's childhood friend. Suzaku is Japanese, but he believes the right way to change the empire is from the inside, as one of its knights. The two friends want some of the same things but choose very different paths. Their clash is at the heart of the drama. Code Geass is famous for its bold plot twists and chess-like plans, where Lelouch tries to think many moves ahead of everyone else. It also asks hard questions. Is it right to do terrible things for a good goal? Can one person change an unfair system without becoming a tyrant? The show mixes big robot battles, school comedy, and serious war drama, sometimes in the same episode. Its ending is one of the most talked-about in anime history, so it is best to go in without spoilers. It is best watched after the first season.
