5

"It doesn't hurt to look back at the past, at least once every year." One day close to Tanabata, the members of Procellarum are at one of Japan's scariest haunted houses at an amusement park for filming for a television program. On the day of filming, Fuduki Kai, one of the members of Procellarum, had a certain dream. It was a dream that was filled with memories of Tanabata――. As soon as filming began, Kai, who was paired up with Rui, saw something and disappeared, chasing after that something. (Source: Tsuki no Uta Wiki)
