To commemorate the release of their new album "EGG", flumpool have launched a special website for the album's lead track "Kaihouku".
On "kaihouku.jp", you can view a special video for "Kaihouku". By adjusting the volume bar, you can manipulate the members performances in the video. When you put the volume at max, there is a scene where actor Nukumizu Yoichi makes an appearance.
The members commented, "It's very fascinating and you can see many different worldviews, so we want many people to try it."
