There are 3 different versions of this single. This is the CD-only version, with Atsushi on the cover. There is another version with this same cover, featuring a bonus DVD. The third version is CD-only, but features a cover image from the cartoon show "xxxHolic", as "Kagerou" was used as one of the ending theme songs to the show.

(Note that in the case of both track titles, the text that appears next to the title separated by a dash is just the same title written again in Kana. This is done to aid people who are unfamiliar with these words, letting them know how to properly read/pronounce the characters.)
