I was hoping to have time so I could watch this OVA. I loved the two seasons of Code Geass and I thought that I would love it. I have never been so disappointed with an anime/OVA.
Although the story is a bit funny at some points (it has references to the TV series), is quite boring most of the time. There is no animation: 28 minutes of frames or drawings without even moving the lips when talking.
I mark it with a 4 (despite the fact that it maybe deserves less) just because I like the characters and it reminded me of the anime, that was one of the first ones I saw.
