The opening is a perfect display of older siblings taking things too far just to make a statement even if it means they'll miss out on tasty treats. I guess it has something to do with principles. The lighting they used made for some dynamic shots, and made the characters look serious for the most outlandish parts. I loved every minute of it. Rare to see the match up of Kana, Maki, and Uchida, but when they do meet, it's never a dull moment. Later on that day the two younger sisters make there own mayhem while Haruka is out. I see a noticeable improvement in the quality of the art, and the animation is as nice as every. The characters look crisp, straight out of the press!
