Ar tonelico: Melody of Elemia, known in Japan as Ar tonelico Sekai no Owari de Utai Tsuzukeru Shōjo (アルトネリコ世界の終わりで詩い続ける少女, Aru toneriko Sekai no Owari de Utai Tsuzukeru Shōjo?, literally "Ar tonelico: The Girl Who Continues to Sing at the End of the World") is a PlayStation 2 console role-playing game produced by Banpresto and Gust. There were other media releases based on the game, including the comic Ar tonelico -arpeggio-, the OVA Ar tonelico, and several drama CDs.
The story begins on the floating landmass named Sol Ciel (ソル・シエール). The setting for the game is an extremely tall tower named Ar tonelico and the plot is mainly about relationships between humans and an artificial race called Reyvateil (レーヴァテイル).
At E3 2006, Nippon Ichi Software America (NIS America) announced that it would pick up Ar tonelico, with an expected release date on October 31, 2006. However, that release was delayed until February 6, 2007 to provide more time for localization.
The European version was released by 505 Games on May 22, 2007. However, it was released in very limited quantities only in France and Italy and as such European copies of the game are rare and the very existence of the PAL-version remained widely unnoticed.
A sequel under the name Ar tonelico II: Sekai ni Hibiku Shoujotachi no Metafalica was released in Japan on October 25th, 2007, and will be released January 20, 2009 in the U.S. under the title Ar tonelico II: Melody of Metafalica.
