Code Geass: Akito the Exiled (コードギアス 亡国のアキト, Kōdo Giasu Bōkoku no Akito) is a theatrical OVA. It was officially announced in the bonus materials of Code Geass: The Miraculous Birthday. The new theatrical OVA is directed by Kazuki Akane (of Vision of Escaflowne and Noein: Mou Hitori no Kimi e fame) and once again features original character designs by CLAMP. It is a side-story that occurs between seasons one and two of Code Geass.

The side story takes place in 2017 a.t.b., between the rise of the “Black Knights” organization and the return of the supposedly "dead" Zero. The setting is in Europe, where the European Union (E.U.) allied nations are being invaded by the overwhelming forces of the Holy Britannian Empire. On the verge of defeat, the E.U. army forms a special unit known as “W-0″, of which a young pilot named Akito Hyuga is a member. Leila Malcal , a former Britannian Aristocrat comes to the European Union for aid, commanding the Wyvern Knightmare corps comprised of Japanese teenagers. They recklessly plunge into a battlefield, where the survival rate is extremely low, at about 5% only. They fight for their freedom and for a home to which they can return.
