If you can get past the ridiculous fight music then it's worth watching for continuity of character/story.

Plot

The story takes place in Europe in the year a.t.b. 2017. A Knightmare unit made of boys and girls from Area Eleven are thrown into a military operation with a 5%chance of survival. They must rescue an allied unit left behind on the European war front.

This takes after the ending of season, if you are watch code geass I recommend after season you watch this side story.

We are introduced to Lelia a sexy looking woman who is the main general, Akito a character who is similar to lelouch and the three kids/rebels.

It's an in between season of Code Geass that does justice seeing what occured between that time. Akito Hyuga had to fight the last of his family that he had left. He got the satisfaction he desired bur the nightmare is far from over. I loved ever minute of this and will watch it again cause i own it and the english dub is great
