I'm happy to say there is an r3. A lot of people have been debating whether there is or not, but I did find proof.The site is www.onemagma.com . Its not a episode as yet ,but I know there is a story so I'm pretty sure there going to make another episode.Heres an review I found about chapter 1.
An alternate Code Geass story in which Lelouch's fate is unknown after his meeting with C.C., whether he be dead or alive. Nunnally makes a Geass contract and gains the power to read the lines of the future. She also obtains a new body and takes up piloting an unusual Knightmare Frame.
I hope this helps!:)
