couldn't agree more with kyouray: the music... there was just something wrong with it; hopefully it was just for the promotional video and it's not going to be the same for the anime. It's good to have a clean version of the comiket trailer, though. Those few seconds of kaichou/bouchou made me very happy.
Expect a large female cast!
Saki's last line is exactly the same as the Drama CD... XD
On a random note, they are still frigging huge...
