Λucifer (sometimes spelled Aucifer, pronounced Lucifer because of the greek letter "L" lambda "Λ") is a Japanese rock group, best known for contributing several of their songs to the popular anime, Kaikan Phrase. The band was formed in 1999, and disbanded in early 2003. They officially debuted on 15 September 1999 with their big hit single Datenshi BLUE, and became increasingly popular thereafter.
Λucifer was put together for the Kaikan Phrase anime to promote it. The anime was based on the popular shoujo manga by Mayu Shinjo. The band members of real life Λucifer changed their names to match with their anime/manga counterparts, except for the vocalist. Several of Λucifer's songs were used in the anime, along with songs of other j-rock bands like GLAY, Feel and e.MU. However, the band decided to go on even after the anime had ended, and continued to release more music afterwards.
Then finally on 25 October 2002, over two and a half years after the anime had ended, they announced that they were breaking up. Following the announcement, they did their last tour entitled "Λucifer Last Live 2002-2003 Energy" from 16 December 2002 to 10 January 2003, which included 9 shows. After that, they appeared for the last time in a TV music show, PopJam, on 11 January and then did their very last show (which was also their first show done abroad) at the Impact Arena in Bangkok, Thailand on 19 January.
At first, on the first album, the music was written by Takuya Asanuma (JUDY AND MARY), Chisato (Penicillin) and IPPEI & TAIZO (FEEL) but after that, the members of the band started writing more. BEATRIP featured one song from Atsuro and one from Santa, and the rest were by Takuya and Chisato, but by the third album, nearly all the music had been done by members of the band, save for one song by Takuya, and two of the songs Makoto did that were done as a collaboration with Masaki. The lyrics on the first two albums were all done by Mori Yukinojo (except for one song on BEATRIP, when Makoto did them). On the third album, only the lyrics to the song by Takuya were made by Mori and the rest were done by the band members.
