i was overwhelmed with excitement when i heard this there was an upcoming parody of the amazing book Alice in wonderland and i was もっと見る than glad that Code Geass was included, it was released on July 27, 2012, and here are the characters :
Lelouch Lamperouge as Mad Hatter
Nunnally Lamperouge as Alice
Shirley Fennete as fawn
Anya Alstreim as white rabbit
Rivalz Cardemonde as Dormouse
Kanon Maldini as The Red Queen
Schneizel el Britannia as The Red King
Gino Weinberg as The Red Knight
Cornelia li Britannia as The White King
Euphemia li Britannia as The White Queen
Villetta Nu as The Gryphon
Nina Einstein as The Cook
Milly Ashford as The Duchess
Cécile Croomy as Walrus
Rolo Lamperouge as Mock Turtle
Lloyd Asplund as Carpenter

and so much more!!
it begins when Lelouch used his ultimate power of geass to spoil her sister who loves Alicein wonderland, they both traveled in a different time, wherein Lelouch is the mastermind of everything, (he narrates the story) and as the story goes Nunnally finds a white rabbit (anya) and tries to return her watch (in this case her camera) she then tumbles with other casts including Milly, Nina, Kallen, Shirley, Rolo, Villeta, Lloyed, Cecille, and so much more!

this is an OVA must see for the ファン "of this great anime" its really an enjoyable thing because they managed to make fun of Code geass for the viewers to realize that Lelouch is not just thinking about planning a rebellion, rather he's just a simple and caring brother who wants to make his sister a better life.. and i hope あなた realize that when あなた watch this!!

Enjoy!! :))
