Just finished seeing Code Geass. What a great anime, I would have to say it's one of the best anime I've seen in quite some time. I highly recommend it.
Anyways the song is Innocent Days by Hitome. Absolutely amazing piece, very powerful. There are plenty of ways to download this song, I put up a youtube link, but the chances that it'll be gone/removed by the time this goes up is high.
