Aria (アリア) is an utopian science fantasy manga by Kozue Amano. The series was originally titled Aqua (アクア Akua) when it was published by Enix in the magazine Monthly Stencil, being retitled when it moved to Mag Garden’s magazine Comic Blade. Aqua was serialized in Stencil from 2001 to 2002 and collected in two tankōbon volumes. Aria was serialized in Comic Blade from November 2002 to April 2008 and collected in twelve volumes. The series has been adapted as an anime television series, with a first season broadcast in 2005, a second season in 2006, an OVA released September 2007, and a third season in 2008 that ended around the same time as the manga serialization. A new OVA, called Aria the Avvenire, was released in the 10th anniversary Blu-Ray Box sets of the anime series between 24 December 2015 and 24 June 2016.
