Finally received the 2nd volume of the 2nd season today after having its original release date delayed due to the earthquakes, and then having to wait til the Easter public holidays were over before I could pick it up from my local post office. There's a special bonus mini video featuring Kurumi called "Mini Todo" which I've yet to watch.
EDIT: Just watched the DVD special short. It's a take on the Cinderella fairytale with Kurumi as Cinderella and Sawako as the evil stepmother and fairy godmother LOL. I took screencaps for those interested in the short below. Funny how they used an eggplant as the horse and the terrible fate it comes to at the end XD.
