The brief synopsis in the following is the courtesy of
ANN:
In the all-new story, Lelouch makes the ultimate use of his Geass power for his little sister Nunnally, who loves Alice in Wonderland.
At this time, it is unknown how many episode this OVA will be comprised of, but it is safe to expect there is going to be more than one episode. The cast pretty much remains the same with all the familiar voices brought back. Enjoy the discussion!
