OK, so I went through the album yet again with the story in mind and all I could find on Japanese sites, and compiled this list (obviously might not be 100% accurate until detailed LIVE reports/DVD?). Maybe someone finds it useful. I sure appreciate this CD even more now that I know more about the story/characters. ^^
