Devil Soldier (戦慄の奇蹟, Senritsu no kiseki) is the second studio album by Japanese heavy metal band Loudness. It was released in 1982. The American Daniel McClendon (brother of Tommy McClendon) was called to engineer the sound of this album, because there was no Japanese technician experienced enough in heavy metal records at the time. The album won the award for Best Heavy Metal record of the year in Japan. The reissue in CD of 2005 contains two bonus tracks, coming from the second single of the band.
