2nd Story CD Thanatos is the second doujin album released by Revo on August 11th, 2002. It contains 7 tracks and 8 bonus WAV tracks. It was released at the 62nd Comiket. The album retailed for ¥1,000 and was the first doujin release to feature narration and vocalizing, being provided by Aramary. 6 of the WAV files are compiled as a Windows Vocal Collection so fans can replace normal Windows sounds with Sound Horizon ones. These files can only be played using a computer. The story of Thanatos was expanded upon with the track "タナトスの幻想は終わらない･･･" on the 2003 Pleasure CD Pico Magic.
