idk if u could call it an OVA.... I say more like a picture drama. IT;s like a sound episode with few pictures to add in. Also there was one fan dvd before R2 started to pick the best scene of R1, and random stuff buy i'm pretty sure that there wasn't any actual OVA.. also FYI Code Geass it self is OVA...... more like ODA XD <<< no one uses this.
