This fandisc includes additional content and a sequel story. This story has you returning to Hokkaido in the summer following your special kiss from the White Illumination festival. There are actually eight separate adventures, one for each girl. You start off by selecting the character with whom you'd like to share your upcoming exploits, and when you arrive back at the Hokkaido airport, she greets you. You travel off through Hokkaido, with the girl conversing with you and showing you around. As you travel, you can surprise the girl by taking a picture of her with the snap of a button, and this picture can be saved to the VMU and viewed later in a photo album.
