A missing piece
Just as they'd promised in the summer, Yu and the others are off on a skiing trip. Remembering that they'll have to say goodbye to Yu in the spring, Yosuke and the others grow sentimental for a moment, but once they decide to "play like there's no tomorrow!" the gloomy mood is swept away. On the slopes, they each enjoy themselves in their own way. But Yu has a gnawing feeling. And it only grows into a solid conviction when they speak of the past, only to discover unnatural gaps in their memories, and when they see a space between them in a photo of them all, as if someone else was originally there, but since erased. At Yu's urging, Yosuke and the others decided to look into the matter. And the next day, when Yu is swept into a sudden snowstorm, he sees a silhouette up ahead...
