エデン (Eden)

Background
The song contains themes of life and rebirth. The biblical, from which the song borrows many concepts, is seen as a form of the afterlife in Abrahamic mythologies. Similarly, Arcadia, a term derived from the Greek province of the same name, is an ideal vision of a peaceful utopia in harmony with nature.

It was featured in the compilation album ELECTLOID feat.初音ミク.
