The story is about Rai, from the PlayStation 2 and PSP Visual Novel Code Geass: Lost Colors, who has lost his memories and one day ends up unconscious at the gates of Ashford Academy and is found by Milly and Lelouch and is taken into the school. Now Rai sets out on his quest to recover his memories while at the same time choose how he will affect the battle for Japan's independence. This story closely follows the events of Code Geass: Lelouch of the Rebellion and Code Geass: Lost Colors with a few twists and turns from the author.

The date is June 2017, seven years after the Holy Britannian Empire invaded and conquered Japan which is now known as Area 11.

And in the midist of this all is a 17 year old boy called Rai who has lost his memories and has ended up at the gate of Ashford Academy where Milly Ashford and Lelouch Lamperouge find and treat him, allowing Rai to stay at Ashford Acedemy while he attempts to recover his memories to find out his true identity. However nobody would know that Rai's appearance in Japan would have an effect on the conflict between Japan and Britannia that would lead to consquences for both sides and the characters involved.
