Lelouch uses his godlike mind-control power to literally rewrite reality into an Alice in Wonderland fever dream, because his sister asked nicely. The entire thing is a slideshow that knows exactly how ridiculous that is. Every joke lands for people who lived with these characters for two seasons, and everyone else will watch twenty minutes of increasingly confident inside jokes and wonder what they're missing.
Nunnally, who loves Alice in Wonderland, is resting under a tree with her brother Lelouch Lamperouge on a calm, sunny day when she asks him for a story. Determined to do everything he can for her, Lelouch turns his Geass to an unusual purpose to give her the most entertaining tale possible. Nunnally wakes up alone beneath the tree and finds that her sight has returned. She soon notices an odd rabbit that looks like Anya Alstreim, the Knight of Six, and it leads to her tumbling down a hole into a vivid wonderland. With Lelouch narrating, the lost Nunnally looks for a way home and meets many colorful, familiar faces along the way. The result is a one-episode comedy fantasy OVA side story in the Code Geass franchise.
