Code Geass: Lelouch of the Rebellion Re;

The story takes place in the same official Code Geass history as the anime, but in a different era. The title character, Renya, is a 17-year-old boy with a mechanical left arm and shuriken throwing stars as his weapons of choice. The story begins when Renya encounters a mysterious, perpetually young witch named "Reifū C.C." C.C. has appeared in Japan's historical Edo era to seek a new partner for a covenant. Meanwhile, a mysterious man, with a striking resemblance to the character Lelouch of the original anime, also appears with unknown intentions.

The story takes place several years after Lelouch's "Zero Requiem" plan.

Code Geass: Oz the Reflection is a spinoff published in Hobby Japan magazine and Kadokawa Shoten's Newtype Ace magazine. It tells a story from the viewpoints of two different protagonists. The story takes place between the first and second seasons of the TV anime and is told from two perspectives. The photo story in Hobby Japan centers around Orpheus Zevon (Jivon), a young terrorist with the Knightmare Frame (KMF) Byakuen who is in pursuit of his lover's killer. The manga in Newtype Ace revolves around Oldrin Zevon, a girl in the Britannia Empire's anti-terrorist unit Glinda Knights who pilots the KMF Lancelot Grail. (Source: Code Geass Wiki)

The Empire of Brittania has invaded Japan using giant robot weapons called Knightmare Frames. Japan is now referred to as Area 11, and its people the 11s. A Brittanian who was living in Japan at the time, Lelouch, vowed to his Japanese friend Suzaku that he'd destroy Brittania. Years later, Lelouch is in high school, but regularly skips out of school to go play chess and gamble on himself. One day, he stumbles on terrorists 11s who've stolen a military secret and is caught by a member of the Brittanian task force sent after them, who is Suzaku. As the rest of the squad arrives, Suzaku is shot for disobeying orders, while the military secret, a young girl, gives Lelouch the power to make anyone obey any order. He takes command of the terrorists and leads them to crush the approaching Brittanian force. However, Suzaku is secretly made the pilot of Brittania's brand new test model Knightmare, Lancelot. Lelouch becomes the masked king Zero to lead the rebellion to defeat Brittania.
