The official website for the Code Geass franchise revealed early January, 2012, that a Nunnally in Wonderland Original Video Animation (OVA) will be released on Blu-ray Disc and DVD this year. Each edition will include a 40-page picture book that recounts the same story as the anime.
Takahiro Kimura, the character designer for the first Code Geass anime, will be the animation director and contribute new designs for this project. In the all-new story, Lelouch makes the ultimate use of his Geass power for his little sister Nunnally, who loves Alice in Wonderland.
Makoto Baba, an episode director on the two television anime series, is directing this new project. Episode scriptwriter Yuuichi Nomura, character designer/animation director Takahiro Kimura, and musical composer Kotaro Nakagawa are also returning from the television series. Bandai Namco Live TV streamed a promotional video.
