Nijiiro Crayon

An album containing several of the songs that Akiko Shikata made and sung for Ar tonelico Qoga: Knell of Ar Ciel, remixed to sound as if they were played from an orgel (music box). This also includes two original compositions, Au GuMu, whose original hasn't been released officially yet, and an extended version of Rainbow Crayon from the Ar tonelico Qoga: Knell of Ar Ciel Original Soundtrack, which also doubles as the titular track of the album.
