Limited edition version includes one bonus track "Ryojoku no Ame" from Dir en grey's May 23, 2008 performance at the Yokohama and is packaged in a paper sleeve. The new single is scheduled to include three songs all set to contrast starkly with the sound of the band's most recent album "The Marrow of a Bone." First, title track "Glass Skin" sees Dir en grey continue farther into the direction started with "Glass Skin" with a brittle, melancholic number. Track two sees Dir remake the semi-acoustic track "undecided" off of 2002's "Kisou" album into the style of the band's current sound. Continuing the acoustic theme, track three features the highly-anticipated unplugged version of recent hit "Agitated Screams of Maggots."

DIR EN GREY“最狂”アルバム『UROBOROS』のリリースが、2008年11月12日に決定した。
1年を超える制作期間を経て完成した本作には、日本語詩のシングルと異なり、英語詩にて歌い上げられた「DOZING GREEN」と「GLASS SKIN」を始め、既にライヴで披露され変幻自在な音で魅了する「STUCK MAN」を含む全13曲が収録されている。
