Aoi Kage 「蒼い影」

Aoi Kage (蒼い影) is the ending theme for Casshern Sins (キャシャーン シンス), the 2008 anime series produced by Madhouse. Performed by Otoyakichiemon'Ju, the song was composed by the same artist and was included in the series soundtrack rather than issued as a standalone single.

Musically, it is a J-Pop track whose lyrics reflect the anime's themes of despair and hope.
