[1] The album was released December 7, 2013 in Japan and internationally on March 7, 2014.

[2] The album features a much heavier, rock-influenced style of music.

The album is the first to feature new band members; Wu-Chy on bass, Higuchuuhei on guitar, Zen on keyboard, and Izu on drums.

Previous releases (with the exception of "Soloween") featured only lead-vocalist Exo-Chika and producer Raveman.

Both the cover and title of the album are an allusion to the 1984 American horror slasher film, A Nightmare on Elm Street.
