Shirley Fenette, Milly Ashford, Rivalz Cardemonde, and Nina Einstein appeared to have stumbled into a secret that Lelouch had been hiding for who knows how long. But they didn't think the secret was anything less than ordinary as they get dragged into adventures of time and space.

Lelouch and C. C., along with the Doctor, attempt to save the day from Prince Schneizel.

Lelouch and C. C. go to London. While there, they meet Rose and the Doctor.

In the beginning, there was Zero. As it was written in history, he lead the greatest revolution that mankind has ever seen. A man with many faces, hidden and proficient at achieving his goals, determined even to the end, he succeeded at the cost of his own life. However, what if something else happened instead as the Multiverse is discovered to be true?

He lives. He could never truly stop watching over the world. But what happens when two beings from outside his universe break his well-laid plans? A Code Geass/Doctor Who crossover. This will be played seriously for the most part. The Empire is reborn...

These are the stories and details in-between the main chapters of Geass Aberration, starting with the first between Delta and Epsilon. These have important stuff in them, so you'll need to read 'em so you don't get confused later. Again,GA is serious biz.
