Elfen Lied is a Japanese manga series written and illustrated by Lynn Okamoto. It was originally serialized in Shueisha's Weekly Young Jump from June 2002 to August 2005, with the 107 chapters collected into twelve tankÅbon volumes. 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.
