The Twilight Valley is the fifth studio album by Japanese group Garnet Crow.

Compared to the original single version, lyrics are performed in different ways and the melodies have a more psychedelic tuning.

[1] This is one of the two GARNET CROW studio albums (the other being Terminus) not to feature a theme song from Detective Conan.

[2] All tracks are composed by Yuri Nakamura, written by Nana Azuki and arranged by Hirohito Furui.
