Paradise Lost is the fifth CD single by Minori Chihara. The single was used as the opening theme song to the anime Ga-rei -Zero- in which she voices the main character Kagura Tsuchimiya. Subsequently, in the 6th episode of The Melancholy of Haruhi Suzumiya-chan, the character Yuki Nagato (reprised by Minori Chihara herself) sang a muted version of Paradise Lost at the end of the episode. The single placed 15th on the Oricon charts in the month it debuted.
