Elfen Lied (エルフェンリート) is a Japanese manga series written and illustrated by Lynn Okamoto. Elfen Lied revolves around the interactions, views, emotions, and differences between human beings and the Diclonii, a mutant species similar to humans in build but distinguishable by two horns on their heads and “vectors”, transparent telekinetically controlled arms that have the power to manipulate and cut objects within their reach. The series is centered on the teenage Diclonius girl “Lucy” who was rejected by human beings and subsequently wants revenge.
The series’ title is German as well as Dutch for “Elves’ Song” or more formally “song of the elves'” and takes its name from the song “Elfenlied”, which is featured in the story. Elfen Lied involves themes of social alienation, identity, prejudice, revenge, abuse, jealousy, regret and the value of humanity. A 13-episode anime television series adaptation was produced by the studio Arms and broadcast on AT-X from July to October 2004.
