After more searching, I found a number more articles on the album and the tour supporting the album, such as http://www.newaudiogram.com/editors/livereview/337120000.php and http://www.ele-king.net/interviews/002411/, including some on major sources like Yahoo Japan: http://headlines.yahoo.co.jp/hl?a=20121024-00000003-lisn-musi. There were also a number of reviews of the album: http://www.liquidroom.net/review2/201209/100%E5%B9%B4%E5%BE%8C/, http://cookiescene.jp/2012/08/orge-you-asshole100vap.php, etc. Combined with the charting and what FunnyPika found, I believe this passes
